MFOM Occupational Health Law Revision

MFOM occupational health law revision is mainly about understanding how UK health and safety, employment and civil law apply to workplace situations. The highest-yield areas include the Health and Safety at Work Act 1974, Management of Health and Safety at Work Regulations 1999, COSHH, DSE, noise and vibration legislation, RIDDOR, the Equality Act 2010 and the distinction between civil and criminal liability.

What occupational health legislation should you know for MFOM?

You do not need to approach occupational health law as if you were preparing for a law degree. For the MFOM, the important skill is recognising which legal framework applies to a workplace scenario and understanding the practical duty created by that framework.

A useful starting point is the Health and Safety at Work Act 1974, often abbreviated to HASAWA Act. It provides the broad statutory framework for occupational health and safety in Great Britain. The Act contains general duties relating to employers, employees, people who control premises and manufacturers and suppliers of articles and substances for use at work.

The legislation is supported by more specific regulations covering particular workplace hazards.

A useful revision map is:

Area	Key legislation
General health and safety	Health and Safety at Work etc. Act 1974
Risk assessment and management	Management of Health and Safety at Work Regulations 1999
Hazardous substances	Control of Substances Hazardous to Health Regulations 2002
Lead	Control of Lead at Work Regulations 2002
Asbestos	Control of Asbestos Regulations 2012
Work equipment	Provision and Use of Work Equipment Regulations 1998
Lifting equipment	Lifting Operations and Lifting Equipment Regulations 1998
Noise	Control of Noise at Work Regulations 2005
Hand-arm and whole-body vibration	Control of Vibration at Work Regulations 2005
Display screen equipment	Health and Safety (Display Screen Equipment) Regulations 1992
Manual handling	Manual Handling Operations Regulations 1992
Work at height	Work at Height Regulations 2005
Workplace incidents	Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013
Personal protective equipment	Personal Protective Equipment at Work Regulations 1992,
Disability and employment	Equality Act 2010

You should memorise the names but more importantly, try to connect each regulation with the occupational health question it helps answer.

For example:

Is the worker exposed to a hazardous substance? Think COSHH, or specific legislation such as lead or asbestos.
Is there a requirement for health surveillance? Consider the relevant hazard-specific legislation and whether the legal criteria for surveillance are met.
Is the concern excessive workplace noise? Think Control of Noise at Work Regulations 2005.
Is the worker using vibrating tools? Think Control of Vibration at Work Regulations 2005.
Is a worker struggling because of a disability? Think Equality Act 2010 as well as the occupational health assessment.
Has a serious workplace incident occurred? Consider RIDDOR.

The legislation is current only at a particular point in time, so candidates should check the current wording before the examination. This is particularly important because legislation can be amended after revision resources have been written.

What is the Health and Safety at Work etc. Act 1974?

The Health and Safety at Work etc. Act 1974 is one of the most important pieces of legislation for occupational medicine.

Section 2 establishes the employer's general duty towards employees, including a duty to ensure, so far as is reasonably practicable, their health, safety and welfare at work.

Section 3 extends duties to people other than employees who may be affected by the undertaking.

Employees also have duties under the Act. Section 7 includes a duty to take reasonable care for the health and safety of themselves and others who may be affected by their acts or omissions at work, and to co-operate with their employer so far as necessary to enable the employer to perform or comply with relevant statutory duties.

These provisions are important because an MFOM question may describe a workplace hazard and ask who has a legal duty.

Do not assume that occupational health is responsible for controlling the hazard. We are not. The employer has the primary responsibility for managing workplace health and safety. The occupational health professional may provide assessment, surveillance, advice and recommendations, but this does not transfer the employer's legal responsibilities to the occupational health service.

What does "so far as is reasonably practicable" mean?

This phrase is important in UK health and safety law.

It does not mean that an employer must eliminate every conceivable risk regardless of cost or difficulty. In broad terms, it involves balancing the risk against the sacrifice involved in taking further precautions. The precise legal interpretation is more nuanced than simply saying "do what is practical".

An SBA might present a significant workplace hazard and several proposed actions. The question may be testing whether the employer has properly assessed and controlled the risk rather than whether occupational health can simply declare the worker fit or unfit.

What are the Management of Health and Safety at Work Regulations?

The Management of Health and Safety at Work Regulations 1999 provide a more detailed framework for managing workplace health and safety.

For MFOM purposes, risk assessment is particularly important.

Regulation 3 requires employers and certain self-employed people to undertake suitable and sufficient assessments of risks to employees and others arising from their work.

Where the employer has five or more employees, the significant findings of the assessment and any group of employees identified as being especially at risk must be recorded.

The Regulations also cover arrangements for effective planning, organisation, control, monitoring and review of preventive and protective measures, health and safety arrangements, health and safety assistance, information, co-operation and co-ordination, and specific considerations for certain groups of workers.

For an occupational physician, this matters because a clinical assessment is only one part of the risk management process.

For example, if a worker develops occupational asthma, the occupational health assessment may identify a relationship between symptoms and workplace exposure. The employer must then consider the workplace risk, exposure controls and whether further measures are required. Health surveillance should not simply become a mechanism for detecting disease while leaving the exposure unchanged.

What is COSHH and when does it apply?

The Control of Substances Hazardous to Health Regulations 2002, commonly known as COSHH, cover risks to health from hazardous substances at work.

COSHH is highly relevant to occupational medicine because it connects workplace exposure, risk assessment, control measures and health surveillance.

A COSHH assessment should consider:

What hazardous substances are present?
How are workers exposed?
Who may be exposed?
What are the health effects?
What control measures are already in place?
Are the controls adequate?
Is exposure monitoring required?
Is health surveillance required?
Are workers appropriately informed and trained?

Hazardous substances are not limited to chemicals supplied with hazard labels. Workplace processes can generate hazardous dusts, fumes, vapours and gases.

Examples include:

Welding fume
Wood dust
Respirable crystalline silica
Isocyanates
Solvents
Biological agents
Certain substances causing occupational dermatitis or asthma

HSE guidance explains that health surveillance under COSHH is appropriate in particular circumstances where there is a recognised disease associated with the substance, it is possible to detect the disease or adverse change and workplace conditions make disease reasonably likely.

A key exam distinction is that health surveillance is not the same as general health screening.

The purpose of occupational health surveillance is to detect adverse health effects related to workplace hazards and evaluate whether control measures are working.

Lead and asbestos have their own specific legislation, so do not automatically treat every hazardous substance question as a COSHH question.

What legislation covers noise and vibration?

Noise and vibration are common occupational health examination topics.

The Control of Noise at Work Regulations 2005 establish exposure action values and an exposure limit value. The lower daily or weekly exposure action value is 80 dB(A), the upper exposure action value is 85 dB(A), and the exposure limit value is 87 dB(A), taking account of the protection provided by hearing protection where applicable.

The Regulations also specify peak sound pressure values.

For MFOM questions, understand what the different thresholds mean rather than simply memorising numbers.

A question may ask what action is required when exposure reaches a particular level. The answer may involve risk assessment, information and training, hearing protection, hearing protection zones, exposure reduction or health surveillance depending on the circumstances.

For vibration, the Control of Vibration at Work Regulations 2005 apply to risks from hand-arm and whole-body vibration. For hand-arm vibration, the exposure action value is 2.5 m/s² A(8) and the exposure limit value is 5.0 m/s² A(8).

This connects directly with occupational health practice because health surveillance may be relevant for workers at risk of hand-arm vibration syndrome.

Our MFOM Occupational Hygiene Revision Essentials covers occupational hygiene concepts that complement the legal framework, including exposure assessment and workplace controls.

What should you know about RIDDOR for MFOM?

The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013, known as RIDDOR, require certain work-related incidents, injuries, diseases and dangerous occurrences to be reported to the relevant enforcing authority - the HSE.

Not every workplace accident is reportable.

For example, RIDDOR includes specified injuries to workers, certain occupational diseases and specified dangerous occurrences. The HSE website has a list of RIDDOR reportable conditions.

A useful exam approach is to distinguish between:

A worker becoming unwell
A worker suffering a reportable occupational disease
A work-related accident causing a specified injury
An accident resulting in more than seven consecutive days' incapacitation
A dangerous occurrence

For certain reportable occupational diseases, the disease must be diagnosed and linked to specified occupational exposure or work activity.

A common trap is assuming that every occupational illness automatically requires a RIDDOR report. The reporting criteria must actually be met.

The occupational health physician may be involved in identifying or diagnosing occupational disease, but the legal reporting duty falls on the person specified by RIDDOR, such as the responsible employer or self-employed person, depending on the circumstances.

What should you know about the Equality Act 2010?

The Equality Act 2010 is particularly important for occupational physicians because many management referrals involve disability, long-term health conditions and reasonable adjustments.

The Act defines disability using the concept of a physical or mental impairment having a substantial and long-term adverse effect on the person's ability to carry out normal day-to-day activities.

The Act provides protection against several forms of discrimination, including direct discrimination, indirect discrimination, discrimination arising from disability, harassment and victimisation.

For occupational health, reasonable adjustments are particularly important.

The duty to make reasonable adjustments can apply where a provision, criterion or practice, physical feature or lack of an auxiliary aid places a disabled person at a substantial disadvantage compared with people who are not disabled.

An occupational health physician should therefore avoid reducing an assessment to:

"Is this person fit or unfit?"

A better occupational health assessment considers the person's functional limitations, the essential requirements of the role, workplace factors and whether reasonable adjustments could reduce a disadvantage.

What is discrimination arising from disability?

Section 15 of the Equality Act concerns discrimination arising from disability. This is one of the commonest claims seen at employment tribunals.

This can arise where a disabled person is treated unfavourably because of something arising in consequence of their disability, unless the treatment can be justified as a proportionate means of achieving a legitimate aim. The protection also has a knowledge requirement concerning the disability.

This is different from direct discrimination because the unfavourable treatment does not necessarily have to be because of the disability itself.

For example, absence associated with a disability may constitute something arising in consequence of disability. The occupational health physician should therefore be careful when advising managers about disability-related absence, capability and adjustments.

What is the difference between civil and criminal law?

This distinction is a frequent occupational medicine revision area.

Criminal law is concerned with offences against the state and is generally enforced by bodies such as the HSE or other enforcing authorities in appropriate circumstances. Prosecution may follow a breach of health and safety legislation.

Civil law is concerned with disputes between individuals or organisations and can include claims for compensation following injury or loss.

A workplace injury can therefore potentially involve both criminal and civil legal considerations.

A useful distinction is:

Civil law	Criminal law
Usually concerns liability between parties	Concerns offences
Compensation is a common remedy	Punishment or other criminal sanctions may result
Negligence is an important concept	Breach of statutory requirements may constitute an offence
Claims may be brought by an injured person	Prosecution is generally brought by an enforcing authority

The exact rules vary according to the cause of action and legislation involved, so avoid assuming that every breach automatically creates a civil claim.

What common law principles should you know?

Not all occupational health law comes from Acts and Regulations.

Common law principles are also relevant, particularly negligence and employer liability.

For negligence, a claimant generally needs to establish the relevant legal elements, including a duty of care, breach, causation and damage.

MFOM questions may also test concepts such as vicarious liability, where an employer may be legally responsible for certain wrongful acts committed by an employee in the course of employment. The precise circumstances are important.

Two classic legal concepts that can appear in occupational medicine revision are volenti non fit injuria and the eggshell skull rule.

Volenti concerns voluntary assumption of risk and is subject to important limitations. Simply knowing that a workplace is hazardous does not automatically establish a successful volenti defence.

The eggshell skull principle means that a defendant generally takes the claimant as they find them. A pre-existing vulnerability does not necessarily protect a defendant from liability for the consequences of an injury.

These concepts are worth understanding because exam questions may use a short workplace vignette to test the underlying principle rather than asking for the name of a case.

How should you approach an MFOM occupational health law SBA?

Legal questions can be challenging because several answers may sound reasonable. The key is to identify the precise legal issue being tested.

Use a structured approach:

Identify the hazard or employment issue. Is this about chemicals, noise, disability, an accident, negligence or confidentiality?
Identify the legal framework. Which Act or Regulations apply?
Identify who has the duty. Is it the employer, employee, occupier, manufacturer, responsible person or another party?
Identify what the duty actually requires. Do not infer more from the name of the legislation than the legislation says.
Look for exceptions or qualifications. Many legal duties are conditional.
Separate legal duties from good practice. A recommendation may be sensible without being a specific statutory requirement.
Read the question carefully. If it asks for the most appropriate legal action, do not answer with a general occupational health recommendation.

A useful revision technique is to create a one-page table linking each major regulation to:

The hazard
Who it applies to
The main employer duty
The occupational health relevance
Whether health surveillance may be relevant
Common examination traps

This turns a large body of legislation into a practical revision framework.

What are the common occupational health law traps in MFOM questions?

The most common errors are often caused by choosing an answer that is broadly sensible but does not answer the specific legal question.

Watch for these traps:

Confusing COSHH with specific legislation: lead and asbestos have specific regulatory frameworks.
Assuming every accident is RIDDOR-reportable: the reporting criteria must be met.
Assuming occupational health owns the risk assessment: workplace risk management remains an employer responsibility.
Confusing health surveillance with screening: surveillance should relate to occupational health risks and form part of an appropriate control strategy.
Assuming a disability automatically means someone cannot perform a job: the Equality Act requires consideration of reasonable adjustments.
Confusing civil and criminal liability: compensation and prosecution are different legal processes.
Assuming an employee accepting a risk removes the employer's duties: this is not a reliable interpretation of UK health and safety law.
Treating an ACOP as legislation: an Approved Code of Practice is not itself the same thing as a statutory regulation, although it has a special legal status and may be used in enforcement proceedings.
Memorising outdated figures: exposure limits, statutory provisions and guidance can change, so check current sources before the examination.

How should you revise occupational health law for MFOM?

A good law revision strategy is to move from broad principles to scenario-based questions.

Start by learning the major legislation and what problem each piece of legislation addresses. Then add the high-yield details that are repeatedly applied in occupational medicine.

Your revision list could include:

HSWA 1974 and general duties
Reasonably practicable
Management of Health and Safety at Work Regulations
Risk assessment
COSHH
Lead
Asbestos
Noise
Vibration
DSE
Manual handling
Work at height
PUWER
LOLER
RIDDOR
Equality Act
Civil versus criminal liability
Negligence
Vicarious liability
Confidentiality and occupational health information
Consent and disclosure
Common law principles

You should then practise applying the law to realistic occupational medicine scenarios.

For example, rather than asking yourself "What is COSHH?", ask:

"A worker develops occupational asthma while using a respiratory sensitiser. What should the employer and occupational health service consider?"

That forces you to integrate legislation, risk assessment, exposure control, health surveillance and clinical assessment.

Frequently asked questions

Do I need to memorise every UK occupational health regulation?

No. You should know the major legislation and understand which workplace hazards and duties it addresses. The exam is more likely to reward accurate application of legal principles to a scenario than indiscriminate memorisation of legislation names.

Is the Health and Safety at Work Act the same as COSHH?

No. The Health and Safety at Work etc. Act 1974 provides a broad statutory framework for workplace health and safety, while COSHH provides specific requirements concerning risks from hazardous substances. Other hazards, such as lead and asbestos, are also subject to specific legislation.

Does occupational health have responsibility for workplace risk assessments?

Occupational health can contribute specialist advice about health risks, surveillance and individual workers, but the employer retains responsibility for managing workplace health and safety risks. The exact allocation of duties depends on the circumstances and applicable legislation.

What is the most important Equality Act issue for occupational physicians?

Reasonable adjustments and discrimination arising from disability are particularly relevant to occupational health practice. The occupational health physician should provide functional, evidence-based advice that helps the employer consider adjustments without making the employment decision on the employer's behalf.

Do all workplace injuries need to be reported under RIDDOR?

No. RIDDOR applies to specified categories of work-related incidents, injuries, diseases and dangerous occurrences. The specific reporting criteria need to be checked rather than assuming that every workplace accident is reportable.

Should I revise occupational health law by memorising sections and regulation numbers?

Knowing a few important provisions can be useful, but understanding the principle is more valuable than memorising large numbers of section references. Build your knowledge around the hazard, legal duty, responsible person and practical occupational health implication, then use SBA questions to test whether you can apply it.

Occupational health law becomes much more manageable when you revise it as a set of practical workplace scenarios rather than as a list of legislation.
