Health and Safety and Industry Practices

Lesson Overview

Understanding UK health and safety legislation is essential for every plumbing operative. This lesson covers statutory acts, enforceable regulations, advisory guidance, and the powers of enforcing authorities.

Learning Objectives

Distinguish between statutory legislation and advisory health and safety guidance.

Identify the core purpose and main objectives of the Health and Safety at Work etc. Act 1974.

State the roles, powers, and enforcement notices issued by Health and Safety Executive inspectors.

The Health and Safety Legal Framework

Health and safety documentation in the United Kingdom is split into two distinct categories: mandatory (statutory) documents and advisory (non-statutory) guidance. You must follow mandatory legislation to comply with the law and avoid criminal prosecution.

Key TermLegislation

A law or group of laws passed by Parliament that are legally enforceable, such as the Health and Safety at Work etc. Act 1974.

Type of DocumentLegal StatusDescription & Examples
Acts of ParliamentMandatory (Statutory)Primary laws passed by Parliament (e.g. HASAWA 1974). They create legal frameworks and duties.
RegulationsMandatory (Statutory)Specific rules and administrative codes enforced under an Act (e.g. PUWER 1998, EAW 1989, COSHH 2002).
Approved Codes of Practice (ACOPs)Advisory / Quasi-legalPractical guidance on complying with regulations. Proof of ignoring an ACOP can be used as evidence of guilt in court.
Guidance NotesAdvisory (Non-statutory)Technical guidance published by the HSE to help interpret the law. Following them is usually enough to comply with legislation.

Exam Tip

In City & Guilds exams, remember that while failing to follow an ACOP is not an offence in itself, failing to follow it will be used in court as evidence that you failed to comply with statutory regulations unless you can prove you complied by other means.

The Health and Safety at Work etc. Act 1974 (HASAWA)

The Health and Safety at Work etc. Act 1974 is the principal piece of occupational health and safety legislation in the UK. It acts as an umbrella or 'enabling' act, providing the foundations from which more specific regulations (such as COSHH or PPE regulations) are developed.

The Act applies to all work activities and covers employers, employees, and self-employed people. It covers all people at work except domestic servants in private employment. Furthermore, it protects members of the public who may be affected by workplace activities.

The Four Main Objectives of HASAWA

  • To secure the health, safety, and welfare of all people at work.
  • To protect members of the public and others from risks arising out of work activities.
  • To control the obtaining, keeping, and use of explosives and highly flammable substances.
  • To control emissions into the atmosphere of noxious or offensive substances.

British Standard / Regulation

HASAWA 1974 covers people and their activities rather than specific buildings or processes. Its general duties require everyone on site—from the client and architect down to the plumber and apprentice—to take responsibility for site safety.

Enforcing Authorities

Health and safety law is enforced across the UK by two bodies working in partnership: the Health and Safety Executive (HSE) and local authorities. Their joint liaison is managed through the Health and Safety Executive/Local Authorities Enforcement Liaison Committee (HELA).

Key TermHealth and Safety Executive (HSE)

The UK government body responsible for the encouragement, regulation, and enforcement of workplace health, safety, and welfare.

Inspector Powers and Enforcement Actions

Appointed health and safety inspectors have wide-ranging legal powers. They have the right to enter any workplace at any time without giving notice. During a visit, an inspector can inspect work, take photographs, take samples, examine records, and interview employees.

Action TypeSeverity of BreachDetails & Legal Consequences
Informal ActionMinor / SmallWritten or verbal advice given to the duty holder on how to conform with the law.
Improvement NoticeModerate / SeriousDirect order to remedy a breach. Gives a minimum of 21 days for the duty holder to take corrective action or appeal to a tribunal.
Prohibition NoticeImmediate Serious DangerImmediately stops an activity involving risk of serious personal injury. Work cannot resume until the specified danger is rectified.
ProsecutionSevere / Non-complianceCarried out in court. Summary offences carry fines up to £20,000 or six months' imprisonment; higher courts can impose unlimited fines.

Safety Hazard

A Prohibition Notice takes effect immediately or after a specified time. It completely halts the identified work activity. You must not restart work until corrective action has satisfied the inspector and the notice is lifted.

Key Takeaways

HASAWA 1974 is the primary enabling Act that covers all workers (except private domestic servants) and the general public.

Regulations and Acts are statutory (compulsory), whereas ACOPs and Guidance Notes provide advisory guidance.

Health and safety law is enforced jointly by the HSE and local authorities via the HELA liaison committee.

Inspectors have the legal power of unannounced entry and can issue Informal Action, Improvement Notices (minimum 21 days), or immediate Prohibition Notices.
