Competence: What does this mean? How can this be assessed

Competences for Core Criteria for demonstration of Competence: Companies, Contractors, Co-ordinators and Designers

The tables below should help to understand and assess the standards you are required to meet the standards set out in the core criteria table below.

·        Column 1 of the table lists the elements which should be assessed when establishing whether or not a company is competent for the work which they will be expected to do.

·        Column 2 lists the standards against which the assessment should be made.

·        Column 3 gives some examples of how a company might demonstrate that it meets these standards.

Companies do not have to produce all of the evidence listed in column 3 to satisfy the standard – but they need to produce enough evidence to show that they meet the standard in column 2, taking account of the nature of the project and the risks which the work entails. This requires you to make a judgement as to whether the evidence provided meets the standard to be achieved.

If your judgement is reasonable, and clearly based on the evidence you have asked for and been provided with, you will not be criticised if the company you appoint subsequently proves not to be competent when carrying out the work.

The assessments should focus on the needs of the particular job and should be proportionate to the risks arising from the work. Unnecessary bureaucracy associated with competency assessment obscures the real issues and diverts effort away from them.

If you’re an employer with less than 5 persons working for you, you do not have to write down your policy, organisation or arrangements under criteria 1 and 2. However, you do need to demonstrate that your policy and arrangements are adequate in relation to the type of work you do. Assessments of competence will be made easier if your procedures are clear and accessible.

‘Contractor’, ‘Designer’ and ‘Co-ordinator’ relate to your function, not to the type of organisation.

	Criteria	Standard to be achieved	Examples of the evidence that you could use to demonstrate you meet the required standard
	Stage 1 assessment
1	Health and safety policy and organisation for health and safety	You are expected to have and implement an appropriate policy, regularly reviewed, and signed off by the managing director or equivalent. The policy must be relevant to the nature and scale of your work and set out the responsibilities for health and safety management at all levels within the organisation.	A signed, current copy of the company policy (indicating when it was last reviewed and by whose authority it is published). Guidance on writing company policies for health and safety can be found in HSE free leaflet INDG 259.
2	Arrangements	These should set out the arrangements for health and safety management within the organisation and should be relevant to the nature and scale of your work. They should set out how the company will discharge their duties under CDM (2007). There should be a clear indication of how these arrangements are communicated to the workforce.	A clear explanation of the arrangements which the company has made for putting its policy into effect and for discharging its duties under CDM (2007). Guidance on making arrangements for the management of health and safety can be found in HSE free leaflet INDG 259.
3	Competent advice – corporate and construction related	Your organisation, and your employees, must have ready access to competent health and safety advice, preferably from within your own organisation. The advisor must be able to provide general health and safety advice, and also (from the same source or elsewhere) advice relating to construction health and safety issues.

You should also have in place a system for reviewing all incidents, and recording the action taken as a result. You should record any enforcement action taken against your company over the last five years, and the action which you have taken to remedy matters subject to enforcement action.	Evidence showing the way in which you record and investigate accidents and incidents. Records of the last two accidents/incidents and the actions taken to prevent recurrence. Records of any enforcement action taken over the last five years, and what action was taken to put matters right. (Information on enforcement taken by HSE over the last five years is available on the HSE website.) For larger companies, simple statistics showing incidence rates of major injuries, over three-day injuries, reportable cases of ill-health and dangerous occurrences for the last three years. Records should include any incidents that occurred whilst the company traded under a different name, and any incidents that occur to direct employees or labour-only subcontractors.

	Criteria	Standard to be achieved	Examples of the evidence that you could use to demonstrate you meet the required standard
9	Subcontracting/ consulting procedures (if applicable)	You should have arrangements in place for appointing competent subcontractors/ consultants.

Examples showing how risk was reduced through design. A short summary of how changes to designs will be managed. (Note: the emphasis here should be on practical measures which reduce particular risks arising from the design, not on lengthy procedural documentation highlighting generic risks.)

	Criteria	Standard to be achieved	Examples of the evidence that you could use to demonstrate you meet the required standard
11	Risk assessment leading to a safe method of work (Contractors only)	You should have procedures in place for carrying out risk assessments and for developing and implementing safe systems of work/method statements.	Evidence showing how the company will identify significant health and safety risks and how they will be controlled. Sample risk assessments or safe systems of work or method statements. If you employ less than five persons and do not have written arrangements, you should be able to describe how you achieve the above.
		The identification of health issues is expected to feature prominently in this system.	This will depend upon the nature of the work, but must reflect the importance of this risk area.
12	Co-operating with others and co-ordinating your work with that of other contractors (Contractors)	You should be able to illustrate how co-operation and co-ordination of your work is achieved in practice, and how you involve the workforce in drawing up method statements/safe systems of work.	Evidence could include sample risk assessments, procedural arrangements, and project team meeting notes. Evidence of how the company co-ordinates its work with other trades.
13	Welfare provision (Contractors)	You should be able to demonstrate how you will ensure that appropriate welfare facilities will be in place before people start work on site.

	Criteria	Standard to be achieved	Examples of the evidence that you could use to demonstrate you meet the required standard
	Stage 2 assessment
1	Work experience	You should give details of relevant experience in the field of work for which you are applying.	A simple record of recent projects or contracts should be kept, with the phone numbers and addresses of contacts who can verify that work was carried out with due regard to health and safety. This should be sufficient to demonstrate your ability to deal with the key health and safety issues arising from the work you are applying for. Where there are significant shortfalls in your previous experience, or there are risks associated with the project which you have not managed before, an explanation of how these shortcomings will be overcome.

Guidance for assessing competence of a co-ordinator for a larger or more complex project, or one with high or unusual risks.

Organisations do not have to produce all of the evidence listed in column 3 to satisfy the standard – they simply need to produce enough evidence to show that they meet the standard in column 2, taking account of the nature of the project and the risks which the work entails. This requires you to make a judgement as to whether the evidence provided meets the standard to be achieved.


If your judgement is reasonable, and clearly based on the evidence provided, you will not be criticised if the companyyou appoint subsequently proves not to be competent to carry out the work.

Remember that assessments should focus on the needs of the particular job and should be proportionate to the risks arising from the work.

Unnecessary bureaucracy associated with competency assessment obscures the real issues and diverts effort away from them.

Note 3      Open to any member of a construction-related institution.

The contents of the health and safety file

1.       When compiling the Health and Safety file, consideration should be given to including information about each of the following where they are relevant to the health and safety of any future construction work. The level of detail should allow the likely risks to be identified and addressed by those carrying out the work:

·         a brief description of the work carried out;

·         any residual hazards which remain and how they have been dealt with (e.g. surveys or other information concerning asbestos; contaminated land; water bearing strata; buried services etc.);

·         key structural principles (e.g. bracing, sources of substantial stored energy, including pre- or post-tensioned members) and safe working loads for floors and roofs, particularly where these may preclude placing scaffolding or heavy machinery there;

·         hazardous materials used (e.g. lead paint; pesticides; special coatings which should not be burnt off etc.);

·         information regarding the removal or dismantling of installed plant and equipment (e.g. any special arrangements for lifting, order or other special instructions for dismantling etc.);

·         health and safety information about equipment provided for cleaning or maintaining the structure;

·         the nature, location and markings of significant services, including underground cables; gas supply equipment; fire-fighting services etc.;

·         information and as-built drawings of the structure, its plant and equipment (e.g. the means of safe access to and from service voids, fire doors and compartmentalisation etc.).

2.       The file does not need to include things that will be of no help when planning future construction work, for example:

·         the pre-construction information, or construction phase health and safety plan;

·         construction phase risk assessments, written systems of work and COSHH assessments;

·         details about the normal operation of the completed structure;

·         construction phase accident statistics;

·         details of all the contractors and designers involved in the project (though it may be useful to include details of the principal contractor and planning supervisor);

·         contractual documents;

·         information about structures, or parts of structures, that have been demolished unless there are any implications for remaining or future structures, e.g. voids;

·         information contained in other documents, but relevant cross-references should be included.

3.       Some of the above items may be useful to the client for later work, or may be needed for purposes other than complying with the CDM regulations, but CDM (2007) does not require them to be included in the file. Including too much material may hide crucial information about risks.

The file does not need to include things that will be of no help when planning future construction work, for example:

·         the pre-construction information, or construction phase plan;

·         construction phase risk assessments, written systems of work and COSHH assessments;

·         details about the normal operation of the completed structure;

·         construction phase accident statistics;

·         details of all the Contractors and Designers involved in the project (though it may be useful to include details of the Principal Contractor and CDM co-ordinator);

·         contractual documents, F10 etc;

·         information about structures, or parts of structures, that have been demolished - unless there are any implications for remaining or future structures, for example voids;

·         information contained in other documents, but relevant cross-references should be included.

The Client’s duty in relation to the health and safety file - Regulation 17

·         The Client shall ensure that the CDM co-ordinator is provided with all the health and safety information in the Client’s possession (or which is reasonably obtainable) relating to the project which is likely to be needed for inclusion in the health and safety file, including information specified in regulation 4(9)(c) of the Control of Asbestos Regulations 2006(a).

·         Where a single health and safety file relates to more than one project, site or structure, or where it includes other related information, the Client shall ensure that the information relating to each site or structure can be easily identified.

·         The Client shall take reasonable steps to ensure that after the construction phase the information in the health and safety file

(1)     is kept available for inspection by any person who may need it to comply with the relevant statutory provisions;

(2)     and is revised as often as may be appropriate to incorporate any relevant new information.

·         It shall be sufficient compliance with paragraph (3)(a) by a Client who disposes of his entire interest in the structure if he delivers the health and safety file to the person who acquires his interest in it and ensures that he is aware of the nature and purpose of the file.

Working Safely

This article defines safe working, the meaning of hazard and risk, hazard identification techniques, basic qualitative risk assessment, selecting or seeking advice on workplace precautions and assisting managers to prepare risk assessments. It concludes with a reminder of statutory responsibilities for health and safety at work.

The term "WORKING SAFELY" may be defined as:

"The collective actions of employees and managers to identify potential hazards in their workplace and either eliminate or control them to an acceptable level, with the common goal of preventing accidents and minimising loss to the compa

In order to work safely employees and managers alike must adopt a proactive approach to health and safety in their workplace that will require a genuine, visible commitment together with personal ownership structured around a control strategy.

A "HAZARD" is defined as "Anything with the potential to cause harm" Harm may include-injuries, ill-health or both. A "RISK" is defined as:

• "The likelihood that a particular hazard will give rise to harm (the extent of the risk covers the population affected and the consequences for them).

Risk therefore reflects both the likelihood and severity of the harm. Hazard Identification

Workplace hazards may be presented in many different forms according to their origin and their physical state. They may comprise of one or all of the following categories:

• Physical hazards - these may include excessive noise, extremes of temperature or exposure to other energy forms such as radiation and electricity. Alternatively, they may be mechanical in  nature such as traps, impact, contact and entanglement with machinery.

• Chemical hazards - these may comprise acids, alkalis, solvents, detergents or other substances known to be hazardous to health. They may produce toxic, harmful, corrosive or irritant effects when in contact with the human body.

• Biological hazards - diseases such as Hepatitis, Legionnaires, Leptospirosis and Anthrax may be contracted from humans or animals or transmitted by other media such as blood, water or the air.

Ergonomic hazards - consideration must also be given to the machine/operator interface. Hazards may include visual and postural fatigue, internal and external manual handling injuries and work related upper limb disorders associated with repetitive movement and strains.

The essential first step in risk control is to seek out and identify hazards. Relevant sources of information include:

• Legislation and supporting Approved Codes of Practice which give practical guidance and include basic minimum requirements.
• HSE guidance.
• Process information.
• Product information.
• Relevant British and international standards.
• Industry or trade association guidance.
• The personal knowledge and experience of managers and employees.
• Accident, ill health and incident data from within the organisation, from other organisations or from central sources.
• Expert advice and opinion and relevant research.

  There should be a critical appraisal of all routine and non-routine business activities.

People exposed may include not just employees but also others such as members of the public, contractors and users of the products and services. Employees and safety representatives can make a useful contribution in identifying hazards.

In the simplest cases, hazards can be identified by observation and by comparing the circumstances with the relevant information (for example single-storey premises will not present any hazards associated with stairs).

In more complex cases, measurements such as air sampling or examining the methods of machine operation may be necessary to identify the presence of hazards from chemicals or machinery.

In the most complex or high-risk cases (for example, in the chemical or nuclear industry) special techniques and systems may be needed such as hazard and operability studies (HAZOPS) and hazard analysis techniques such as event or fault-tree analysis. Specialist advice may be needed to choose and apply the most appropriate method.

  

Risk Assessment

A risk assessment is nothing more than a careful examination of what, at work, could cause harm to people, so that it can be established whether enough precautions have been taken or more should be done to prevent harm. The aim is to make sure that no one gets hurt or becomes ill.

Accidents and ill health can ruin lives and affect business too if output is lost, machinery is damaged, insurance costs increase, or if subject to prosecution.

The important things to be decided are whether a hazard is significant and whether it is covered by satisfactory precautions so that the risk is small. This must be done when assessing risks. For instance, electricity can kill but the risk of it doing so in an office environment is remote provided that 'live' components are insulated and metal casings properly earthed.

HSE Guidance - Five Steps to Risk Assessment STEP 1 - Look for the hazards

Start by walking around the workplace and looking afresh at what could reasonably be expected to cause harm. Ignore the trivial and concentrate on significant hazards that could result in serious harm or affect several people.

Ask other employees or safety representatives what they think. They may have noticed things that are not immediately obvious. Manufacturers' instructions or data sheets can also help spot hazards and put risks in their true perspective. So can accident and ill-health records.

Look for hazards that could reasonably expect to result in significant harm under the conditions in your workplace. Use the following examples as a guide:

• Slipping/tripping hazards (poorly maintained floors or stairs)
• Fire (flammable materials and sources of heat)
• Chemicals (battery acid)
• Moving parts of machinery (blades)
• Work at height (mezzanine floors)
• Ejection of material (plastic moulding)
• Pressure systems (steam boilers)
• Vehicles (fork-lifftrucks etc.)
• Electricity (poor wiring)
• Dust (grinding)
• Fumes (welding)
• Manual handling
• Noise
• Poor lighting
• Low temperature
    

STEP 2 - Decide who might be harmed, and how

Young workers, trainees, new and expectant mothers etc., who may be at particular risk

Cleaners, visitors, contractors, maintenance workers etc., who may not be in the workplace all the time
Members of the public, or people sharing the workplace, if there is a chance they could be hurt by work activities.

STEP 3 - Evaluate the risks and decide whether existing precautions are adequate or more should be done

Risk assessment requires assessment of two factors:

• Likelihood
• Severity

Likelihood

 A subjective assessment of the probability can be reduced to numbered categories as follows. (There are many versions of this technique).

• 5 = Certain or near certain 
• 4 = Very likely
• 3 = Likely
• 2 = Unlikely
• 1 = Very unlikely

Severity

This requires an assessment of the possible outcome of the hazard. Various factors will affect the severity. We can apply a similar procedure to the above and produce a numbered scale as follow:

• 5 = Death
• 4 = Major injury, disabling disease
• 3 = Lost time injury (over 3 days) 
• 2 = First aid injury
• 1 = Minor injury 

Risk Rating

Multiply the Severity number by the Likelihood number to arrive at the risk factor for each hazard. This produces a number on a scale of 1 to 25. These numbers provide an indication of priority and the extent of the risk, the higher the number the greater the priority and risk and therefore the more resources which may be needed to control the risk

This can easily be shown with the use of the risk matrix

Severity	Likelihood	5	4	3	2	1
5		25	20	15	10	5
4		20	16	12	8	4
3		15	12	9	6	3
2		10	8	6	4	2
1		5	4	3	2	1

 

As a rough guide:

16 to 25 is high risk and may require the provision of considerable resources involving special equipment, training, high levels of supervision and consideration of the most effective methods of eliminating or controlling hazards.

6 to 15 is significant risk and will require an appropriate level of resources.

1 to 5 is low risk but actions should still be taken to try to reduce these risks further if possible within reasonable limits

  

The aim is to make all risks small by adding to the precautions as necessary.

If it is found that something needs to be done, an "action list" can be drawn up to give priority to any remaining risks which are high and/or those which could affect most people. In taking action ask:

• Can we get rid of the hazard altogether?
• If not, how can the risks be controlled so that harm is unlikely?

In controlling risks, apply the principles below, if possible in the following order:

• Try a less risky option
• Prevent access to the hazard (by guarding)
• Organise work to reduce exposure to the hazard
• Issue personal protective equipment
• Provide welfare facilities (washing facilities for removal of contamination and first aid)

These are inexpensive precautions considering the risks. Failure to take simple precautions can cost a lot more if an accident does happen.

STEP 4 - Record your findings

If there are fewer than five employees an employer does not need to write anything down, though it is useful to keep a written record of what has been done. But if there are five or more people employed the employer must record the significant findings of the assessment.

This means writing down the significant hazards and conclusions. Examples might be

• Electrical installations - insulation and earthing checked and found sound
• Fume from welding - local exhaust ventilation provided and regularly checked
• Risk assessments ^-must be suitable and sufficient — this means showing that:
• A proper check was made by competent people to identify significant hazards
• Those who might be affected are identified
• All the obvious significant hazards were addressed, taking into account the number of people who could be involve

The precautions are reasonable and the remaining risk is low

STEP 5 - Review your assessment and revise it if necessary

Sooner or later new machines, substances and procedures that could lead to new hazards will be brought in. If there is any significant change, this should be added to the assessment to take account of the new hazard

Do not amend the assessment for every trivial change or for each new job, but if a new job introduces significant new hazards of its own, this must be considered in its own right and action taken to keep the risks down.

It is good practice to review the assessments from time to time to make sure that the precautions are still working effectively

Sources of Information

It is essential to keep abreast of new health and safety legislation and other developments in the health and safety field. Copies of the Acts and Regulations are sold by HMSO. These, however, generally give only a broad outline but it is useful to know the aim of the Act or Regulation.

Extensive health and safety information can be obtained from the Health and Safety Executive (HSE) telephone 01787 881165 (HSE Books), or via their website at http://www.hse.gov.uk/

Publications available include:

• Approved Codes of Practice
• Guidance
• Free leaflets on a wide variety of hazards

Information and advice on occupational health problems can be obtained from the Employment Medical Advisory Service (EMAS). The EMAS telephone numbers are available at local HSE area offices.

Local Authority Environmental Health Departments

Local authorities have responsibility for enforcing health and safety legislation in a wide variety of non-industrial premises, for example at various consumer services, launderettes, restaurants etc.

Organisations Involved in Safety

There are a number of organisations that are involved almost exclusively in Health and Safety and publish monthly journals that are valuable sources of information. These include:

• Institution of Occupational Safety and Health (IOSH) (see above)
• Royal Society for the Prevention of Accidents (RoSPA)
• British Safety Council 

Publications

There are a considerable number of books both general and specific on health and safety published and available from books shops.

British and European Standards
A number of these relate to safety such as BS EN 292 Safeguarding of Machinery and BS EN 166 Eye Protection. Whilst not having legal standing they will be used as yardsticks of good safety practice

Professional Institutes/Trade Organisations

These often produce codes of practice, for example the Institute of Electrical Engineers Regulations on Electrical Installations and Portable Appliance Testing.

Consultants and Specialists

Advice can be obtained from organisations such as Universities, Colleges, and Institutions who offer consultancy services as well as specialists in various areas.

Training Boards

Training Boards specify training standards but some of their publications provide substantial information on safety matters.

Manufacturers and Suppliers
Manufacturers, suppliers and importers have a duty under HASAWA Section 6 to provide information that will enable the users of their products to be able to use them with safety.

Manufacturers of Personal Protective Equipment (PPE) will meet the various British Standards relating to their products and provide the information on their levels of protection.

Trade Unions and the TUC

Unions and the TUC produce guides for Safety Representatives and many Unions also have full time Officers who deal with Health and Safety matters.

Posters and Signs
Employers must display certain statutory notices that provide information to employees. Other posters can be used to remind staff of general workplace hazards or to support specific safety campaigns. Signs remind employees of safety requirements and also draw to the attention of visitors who are not familiar with the workplace potential hazards.

Company Sources

• Company Safety Policy — a legal requirement with five or more employees in the company.
• Job descriptions — responsibilities, hazards and control measures.
• Accident statistics and records.

Health and Safety Statutory Legislation — Application to Employees

The following information is provided to remind people of their general health and safety legal responsibilities at work.

This information must also be provided at the workplace in the form of either:

• A poster prominently displayed in the workplace, entitled "Health and safety law — what you should know"; or
• An approved leaflet given to employees. The Health and Safety at Work etc. Act 1974 Section 7 - Duties of employees at work

1. To take reasonable care for the health and safety of themselves and others who may be affected by their acts or omissions.
2. To co-operate with their employer or any other person so far as is necessary to enable statutory duties or requirements to be complied with.

Section 8 - Duty on all persons

No person must intentionally or recklessly interfere or misuse anything provided in the interests of health, safety or welfare.

The Management of Health and Safety at Work Regulations 1999 Regulation 14— Employees' duties
Employees must use any machinery, equipment, substance etc in accordance with training and instructions given.

Employees must report to employers or others with responsibility for health and safety of employees:

• Work situations that represent serious and immediate danger to health and safety.
• Matters that represent shortcomings in the protection arrangements for health and safety.

Any failure to observe the duties outlined above could lead to individuals being prosecuted in the criminal courts

Wow at last here I am going to update this blog, well did I ever have the toils with the NEBOSH certificate, I passed the first two parts and flunked what I thought was the easy one, not to worry though 18 months later I finally sat the the one I missed and I now I am the proud owner of the NEBOSH Level 3 Certificate in Construction Health & safety

Time Out

Hi there could be a bit of a delay to new posts as I take a time out for study, we have exams in 4 weeks I need that time to concentrate on parts I'm a bit light in, ie practical assessment, so will finish all this later

Element 9 Physical & Psychological Health – Hazards & Control

A slightly different tack on this element as I am a bit behind on the course, but an excellent source of information is Andy Brazier's page http://healthandsafetycertificate.blogspot.com/ lots and lots of stuff here. I even bought his book for a £5 it's a bargain. Below is chapter 13 covering the relevant topic

Physical and psychological hazards

The following can cause physical and/or psychological harm:

Ionising and non-ionising radiation;

• Noise;
  
• Vibrations;
  
• High or low temperatures;
  
• High humidity;
  
• Poor ergonomics - body position;
  
• Repetitive actions;
  
• Fatigue;
  
• Stress.
  

Ionising radiation

Ionising radiation occurs as either electromagnetic rays (such as X-rays and gamma rays) or particles (such as alpha and beta particles). It occurs naturally (e.g. radon gas) but can also be produced artificially. Everyone receives some exposure to natural background radiation.

It is used or occurs in the following work settings

• Medicine (for diagnosis and treatment);
  
• Industry (for measurement and non-destructive testing);
  
• Power generation (nuclear power stations);
  
• Research and teaching.
  

Exposure to ionising radiation can alter human cells. It can cause radiation burns, poisoning and lead to cancer. It can be dangerous to unborn babies. Exposure can be directly from a source of ionising radiation. Consequences can be particularly severe when radioactive material is ingested as the exposure lasts as long as the material is inside the body.

Ionising Radiation Regulations 1999 require employers to make sure exposure is restricted as far as reasonable practicable and is kept below dose limits. Practices must be authorised by the HSE and suitable risk assessments need to be carried out prior to work commencing and reviewed at suitable intervals. Where radiation accidents are reasonably foreseeable, contingency plans need to be developed.

Employers need to appointment Radiation Protection Advisers (often an individual from a specialist company) who achieve competence in the management of risk due to ionising radiation. They should be consulted with to ensure regulations are being complied with.

The regulations specify circumstances when controlled areas need to be defined because people may be exposed to certain levels of ionising radiation within them. Where such areas are necessary it is a requirement to develop .Local Rules. And appoint Radiation Protection Supervisors who have a fundamental role in ensuring compliance with regulations and local rules. They do not need to be present at the worksite at all times, but are the first point of contact for help and advice and so need to be readily available.

People who have the potential to be exposed to certain levels of ionising radiation need to be designated as a .Classified Person. and their dose must be monitored and records kept. Action needs to be taken where someone is exposed to excessive doses of ionising radiation.

Non-ionising radiation

Non-ionising electromagnetic radiation (NIEMR) is the term used to describe the part of the electromagnetic spectrum covering two main regions

1. Optical radiation including ultraviolet (UV), visible light and infrared.
   

   Hazardous exposure may result from the sun, sunbeds, lasers and welding.
   

   
   

2. Electromagnetic fields (EMFs) including power frequencies, microwaves and radio frequencies.
   

   
   

Exposure of the eyes to UV radiation can damage the cornea and produce pain and symptoms similar to that of sand in the eye.

The effects on the skin range from redness, burning and accelerated ageing through to various types of skin cancer.

High-power lasers can cause serious damage to the eye (including blindness) as well as producing skin burns.

Exposure of people to high levels of EMFs can give rise to acute effects. The effects depend on the frequency, with low frequencies affecting the central nervous system and high frequencies causing heating effects that can lead to a rise in body temperature. In reality, these effects are extremely rare and will not occur in most day-to-day work situations

Noise at work can cause hearing loss. This may be temporary, but continued exposure, or short term exposure to very high noise can cause permanent damage.

Also, exposure to high levels of noise can cause tinnitus (ringing, whistling, buzzing or humming in the ears) and working in a noisy environment makes communication difficult and can mean people cannot hear warnings and alarms.

Noise levels are measured in Decibels (dB). Control of Noise at Work Regulations

2005 set limits for short and long term exposure and require employers to:

Assess the risks to their employees from noise at work;

• Take action to reduce the noise exposure that produces those risks;
  
• Provide employees with hearing protection if the noise exposure cannot be reduced enough using other methods;
  
• Make sure the legal limits on noise exposure are not exceeded;
  
• Provide employees with information, instruction and training;
  
• Carry out health surveillance where there is a risk to health.
  

Legal limits are defined in three categories

1. Lower exposure action values which are a daily or weekly exposure of 80 dB or peak sound pressure of 135 dB . above these levels hearing protection must be available for employees (although they do not need to use it) and information and training must be given regarding the risks and controls;
   
2. Upper exposure action values which are a daily or weekly exposure of 85 dB or peak sound pressure of 137 dB . above these levels the noise must be reduced to as low as reasonably practicable and employees must wear hearing protection;
   
3. Maximum exposure limit values which are a daily or weekly exposure of 87 dB or peak sound pressure of 140 dB . exposure must not exceed these levels.
   

A key element of the regulations is that noise levels should be reduced before

considering hearing protection. Employees have a duty to co-operate with their

employers in protecting hearing, including wearing hearing protection provided.

Vibrations

There are two main concerns regarding vibration

1. Whole body vibration
   
2. Hand arm vibration
   

Whole-body vibration is shaking or jolting of the human body through a supporting surface (usually a seat or the floor), for example when driving or riding on a vehicle along an unmade road, operating earthmoving machines or standing on a structure attached to a large, powerful, fixed machine which is impacting or vibrating. It can cause back pain, often aggravating a previous problem.

Hand-arm vibration can be caused by operating hand-held power tools (e.g. road breakers), hand-guided equipment (e.g. powered lawnmowers) or by holding materials being processed by machines (e.g. using pedestal grinders). Regular and frequent exposure to hand-arm vibration can lead to permanent health effects (occasional exposure is unlikely to cause ill health).

Symptoms include:

• Tingling and numbness in the fingers;
  
• Not being able to feel things properly;
  
• Loss of strength in the hands;
  
• The fingers going white (blanching) and becoming red and painful on recovery (particularly in the cold and wet, and probably only in the tips at first).
  
• Continued exposure can mean people cannot use their fingers properly, especially in cold conditions.
  

The Control of Vibration at Work Regulations require employers to:

Assess the vibration risk to employees;

• Decide if they are likely to be exposed above the daily exposure action value (EAV), and if so introduce a programme of controls to eliminate risk, or reduce exposure to as low; and provide health surveillance
  
• Decide if they are likely to be exposed above the daily exposure limit value (ELV) and if they are take immediate action to reduce their exposure below the limit value;
  
• Provide information and training to employees on health risks and the actions you are taking to control those risks;
  
• Consult trade union safety representative or employee representative on your proposals to control risk and to provide health surveillance;
  
• Keep a record of risk assessment and control actions;
  
• Keep health records for employees under health surveillance;
  
• Review and update your risk assessment regularly.
  

The exposure action value (EAV) is a daily amount of vibration exposure above which employers are required to take action to control exposure.

For hand-arm vibration the EAV is a daily exposure of 2.5 m/s2 A(8) and for whole body vibration 0.5 m/s2 A(8)

The exposure limit value (ELV) is the maximum amount of vibration an employee may be exposed to on any single day. For hand-arm vibration the ELV is a daily exposure of 5 m/s2 A(8) and for whole body vibration 1.15 m/s2 A(8)

Temperature

Working in conditions that are too hot can cause heat stress that can affect a person.s ability to work, potentially leading to heat exhaustion and heat stroke (can result in unconsciousness and can be fatal). Also, dehydration.

Working in cold conditions can cause cold stress and hypo-thermia.

Temperatures in the workplace are covered by the Workplace (Health, Safety and Welfare) Regulations 1992. Employers must provide a .reasonable. temperature in the workplace.

It is suggested that the minimum temperature in workrooms should normally be at least 16 degrees Celsius, or 13 degrees Celsius if much of the work indoors involves severe physical effort. A meaningful figure cannot be given at the upper end of the scale because other factors have an affect including radiant temperature, humidity and air velocity.

Humidity

Humidity is the amount of water vapour in air. Levels are usually quoted as relative humidity, which is the ratio between the actual amount of water vapour in the air and the maximum amount of water vapour that the air can hold at that air temperature High relative humidity (>80%) starts to prevent evaporation of sweat from the body. This evaporation is a major way of regulating body temperature. Therefore, high humidity can contribute to heat exhaustion and heat stroke.

Humidity is particularly a concern when people are required to wear extra clothing (i.e. in the form of personal protective equipment PPE). In this case the humidity inside clothing can be significantly higher than outside.

Humidity is covered by the Workplace (Health, Safety and Welfare) Regulations 1992.

Managing the risks associated with physical hazards

Ergonomics

Ergonomics is the application of scientific information concerning humans to the design of objects, systems and environment for human use. The aim is to use this information to ensure comfort, efficiency, productivity and safety. Ergonomics comes into everything which involves people. In a phrase, the job must .fit the person. in all respects, and the work situation should not compromise human capabilities and limitations.

Ergonomics covers anatomy, physiology and psychology.

Neck and back pain

Neck and back pain can arise in many situations, but the following are known to cause problems:

• Heavy manual labour;
  
• Manual handling in awkward places;
  
• Repetitive tasks;
  
• Sitting at a workstation for a long time (especially if not set up properly);
  
• Stooping, bending over or crouching (poor posture);
  
• Pushing, pulling or dragging excessive loads;
  
• Stretching, twisting and reaching;
  
• Prolonged periods in one position, leading to postural strain;
  
• Situations where the whole body is subjected to vibration, jolting and jarring (including driving long distances or over rough ground).
  

As with many ill health conditions, some people are more susceptible to back pain than others.

HSE have dedicated web pages for neck and back pain at

http://www.hse.gov.uk/msd/backpain/index.htm

Work related upper limb disorders (WRULD)

WRULD, sometimes known as repetitive strain injury are problems with the shoulder and arm, including the forearm, elbow, wrist, hand and fingers, and can include neck pain. Any type of work that involves a worker using their arms to carry out tasks can lead to WRULDs, although they are frequently associated with computer use and assembly work. Symptoms include tenderness, aches and pain, stiffness, weakness, tingling, numbness, cramp and swelling.

• Risk factors include:
  
• Repeating an action;
  
• Uncomfortable working position;
  
• Using a lot of force;
  
• Carrying out a task for a long period of time;
  
• Poor working environment;
  
• Psychosocial issues (lack of control or status).
  

Finding solutions is not always easy, and it is important to recognise that people are different sizes, have different abilities and some are more susceptible due to disabilities. Certainly workstation and job design can have a significant impact, but behaviours are equally important, including posture, exercise and taking breaks. People need to be informed of the risks and how to minimise them. If someone contracts WRULD it may be sufficient for them to change their working methods. However, in some cases medical treatment and rehabilitation may be required.

Display screen equipment (DSE)

Poor physical layout of DSE workstations can cause WRULD. Also, screen glare and poor image quality can contribute to tired or sore eyes and headaches (especially for people who wear contact lenses or bi-focal glasses). People using

DSE can suffer from stress due to the expected pace of work or anxiety about new technology.

There is no evidence to suggest radiation from screens is a problem, even for pregnant women. A few people claim skin problems, but this is more likely to be with air quality (that may be affected by electrical equipment) rather than the DSE itself. A small number of epileptics may have problems.

The Health and Safety (Display Screen Equipment) Regulations 1992 require that operators or users have:

• Adequate training and information;
  
• Proper breaks or changes of activity;
  
• Work stations suitable for them which meet, where necessary, the standards in the schedule;
  
• Eye tests if they request them.
  

There are many devices available that are designed to minimise health impacts from using DSE. They include specialised computer mice, document holders and arm rests. As with WRULD, whilst these can assist it is often behaviour (combined with well design standard DSE) that can have the greatest impact.

Working environment

Welfare and hygiene

People cannot remain healthy at work if their basic welfare needs are not catered for. This includes the following:

• Toilets;
  
• Facilities to wash (including showers where necessary);
  
• Drinking water supply;
  
• Places to eat;
  
• Places to change and store clothes (if work clothes are required);
  
• Rest facilities for pregnant women (i.e. reasonably practicable).
  

It is important to recognise that people eating with dirty hands can result in them ingesting hazardous materials. Also, that dirty clothes can mean people taking hazardous materials into their car and possibly home to their family.

Facilities have to be kept clean, in good condition and supplied with materials (e.g. toilet paper, soap). Also, rooms need to be well ventilated and at a reasonable temperature (not too hot or cold).

These requirements are all covered by the Workplace (Health, Safety and Welfare) Regulations 1992.

A safe place to work

The following fall into the category of general safety:

• Lighting must be sufficient for people to work safely;
  
• People need enough space. As a minimum there should be 11m3 per person (with any height above 3m being considered as 3m for this calculation);
  
• Floors and traffic routes must be sound and strong enough. They must not have holes, not be slippery or obstructed;
  
• Handrails must be provided for stairways;
  
• Clear/glass doors must be arranged so people are not liable to walk into them, and they need to be protected against breaking;
  
• It must be possible to clean windows safely;
  
• Doors that swing both ways must allow people to see through so people behind them are not hurt;
  
• Escalators and moving walkways must be of safe design and condition, and have emergency stop buttons.

Stress

Stress is the adverse reaction people have to excessive pressures or other types of demand placed on them. Whilst pressure is an integral part of work and helps to keep people motivated, when it is excessive it can lead to stress. Stress causes chemicals to be released into the body that impact on how the body works. Overtime this can cause significant health problems. Also, stress affects peoples. concentration, information processing and decision making, which undermines their performance and can cause them to commit errors or behave unsafely.

The primary sources of stress at work include:

• High demands, excessive workload, unhealthy work patterns and working poor environment;
  
• Lack of control, no say in the way they do their work;
  
• Lack of support, lack of encouragement and resources from the organisation;
  
• Poor relationship, tension with management or colleagues and a failure to deal with unacceptable behaviour such as bullying;
  
• Poorly defined roles .people not understanding their responsibilities or the scope of their job;
  
• Poorly managed change . people not considered in the change management process or not given sufficient information about what is happening or why.
  

Organisations should have systems in place to manage stress. They should include a policy, organisation and arrangements to identify potential stress (through risk assessment), actual stress (sickness rates) and deal with it. Proactive monitoring of stress, often through the use of staff surveys, should be part of the arrangements. The HSE have a website dedicated to stress at

http://www.hse.gov.uk/stress/index.htm

Fatigue

Fatigue occurs when people get very tired over a long time and/or are unable to rest. It significantly increases the likelihood of human error and over the long term can cause of contribute to stress (with subsequent health problems). Poor working conditions (e.g. noise, lighting, DSE) tend to increase levels of fatigue.

Shift and night work

Shift and night workers are particularly prone to fatigue because their workingpatterns differ from natural .circadian rhythms,. meaning they have to be awake when their body wants to be asleep. They are known to be prone to stomach, heart and psychological problems. Also, working unusual hours can impact on relationships causing stress.

People working at night are likely to be tired and so prone to errors. Also, it is likely to be dark and there is usually less support (e.g. technical), which can create problems.

Good shift patterns and controls over hours actually worked can minimise fatigue.

Plenty of exercise, a healthy diet and getting sleep whenever possible are particularly important for shift and night workers to minimise the risks due to their patterns of work.

Typical Examination Questions based on Element 8

	Factors can include: Blocked filters. Hood placed too far from source of contaminant. Lack of maintenance and testing. Unauthorised alterations. Wear or corrosion of fan blades. Incorrect settings. System overwhelmed by increase in contaminant. Inadequate design
2.	Identify the information that should be included on a hazard data sheet supplied with a hazardous substance.	(8)
	Information should include: The name of the substance. It's chemical properties and composition. The nature of hazards. Relevant standards (e.g. Occupational exposure limits). Precautions to be observed in its transport, handling and use. Measures to take in an emergency (e.g. spillage or accidental exposure) including first-aid treatment and disposal requirements.
3.	a) List the elements of a hierarchy for the control of airborne contaminant (b) Outline TWO reasons why a cartridge-type respirator may in practice fail to provide a sufficient level of protection.	(6) (2)
	Control measures in correct order of use are: Elimination of the substance or its substitution with something less harmful. Possibility of reducing exposure by introducing changes in working methods (e.g. use of brush instead of spray or, pellets instead of dust), or to work patterns. Segregation or enclosure of the process and provision of LEV). Lastly, the provision of PPE. Reasons include: Poor fit of the respirator, either because of the use of other PPE at the same time or facial hair. The use of incorrect cartridge. The cartridge not being properly fitted. Failure to change the cartridge at appropriate intervals. Inadequate storage facilities leading to respirator being damaged or contaminated.
4.	(a) Describe the typical symptoms of occupational dermatitis. (b)State the factors that could affect the likelihood of dermatitis occurring in workers handling dermatitic substances. (6)	(2) (6)
	Symptoms are reddening, blistering and cracking of the skin with a possibility of infection and ulceration. Factors include; the nature of the agent, concentration levels and the duration and frequency of exposure when dermatitis substances are handled. Additional factors that could increase the risks include cuts and abrasions that would allow the chemical to be absorbed more readily. Existing skin conditions, the type of skin and its sensitivity, the specific site of skin contact, poor personal hygiene and the misuse of protective measures are other factors
5.	Outline the Factors to be considered in the selection of respiratory equipment for persons carrying out welding activities
	Factors to be considered include: The nature and concentration of contaminants released from the welding process. The material to be welded including any surface coatings (eg lead paint) and the constituents of the filler materials must all be assessed. Once this has been done a range of suitable respiratory protective equipment that would offer adequate protection can be considered. In doing so consideration would be given to the compatibility of the equipment with the work to be done and any other PPE, ergonomic considerations (Bulkiness, comfort etc.), the level of training required, the duration and use, the ease of maintenance and the costs
6.	(a) Define the term 'target organ' within the context of occupational health. (b) Outline the personal hygiene practices that should be followed to reduce the risk of ingestion of a hazardous substance.	(2) (6)
	(a)Target organs are , the organs of the human body upon which a toxic material exerts it effort. (b) Personal hygiene practices would include, washing hands before eating , the avoidance of eating or drinking and smoking in the workplace, utilising facilities for contaminated clothing, appropriate use of gloves and avoiding hand to mouth contact
