What HASAWA stands for, what the Act requires, who it applies to, and how it is enforced — the foundation of all UK workplace health and safety law.
The short answer
HASAWA — also written HSWA or HASAW — stands for the Health and Safety at Work etc. Act 1974. It is the primary piece of health and safety legislation in Great Britain. It places general duties on employers, the self-employed, employees and others, and every set of health and safety regulations you will meet is made underneath it.
HASAWA, HSWA or HASAW?
This page covers the statute itself — its sections, who it binds and how it is enforced. If you want the broader picture first, start with what health and safety means in UK law and come back.
All three abbreviations refer to the same statute, and the inconsistency confuses people constantly. The Act’s full title is the Health and Safety at Work etc. Act 1974 — the “etc.” is genuinely part of the name, because the Act also covers matters beyond work itself.
| Abbreviation | Where you’ll see it |
|---|---|
| HASAWA | The most common form in training courses and workplace documents. |
| HSWA | Preferred in legal and regulatory writing, including by the HSE. |
| HASAW / HSW Act | Older or informal usage. Same Act. |
If you’re being assessed on it — in a NEBOSH or IOSH exam, for instance — use the full title once and then whichever abbreviation your course materials use.
Why the Act Exists
Before 1974, British health and safety law was a patchwork of industry-specific statutes built up over a century — separate rules for factories, mines, quarries, offices, shops and railway premises. Large numbers of workers fell outside all of them, and the rules that did exist were prescriptive: they told you what to install rather than what outcome to achieve, which meant they aged badly as technology changed.
The scale of the problem was stark. HSE puts the position at the time at roughly 1,000 work-related deaths a year, half a million injuries, and 23 million working days lost annually to industrial injury and disease.
A Committee on Safety and Health at Work, chaired by Lord Alfred Robens, was appointed in May 1970 and reported on 19 July 1972. It proposed something different: a single framework Act placing broad, goal-setting duties on everyone involved in work, supported by detailed regulations that could be updated without new primary legislation, and extending protection to almost all people at work.
The Health and Safety at Work etc. Act 1974 was the result. It received Royal Assent on 31 July 1974, created the Health and Safety Commission that year, and the Health and Safety Executive followed in 1975.
That structure is why the Act has lasted over fifty years with its core duties essentially unchanged. It sets standards rather than specifications.
Who the Act Applies To
Broadly, everyone involved in work in Great Britain. The Act reaches further than most people expect:
Employers
To their employees, and to anyone else affected by what the business does.
The self-employed
Where their work could put others at risk.
Employees
Duties of their own under sections 7 and 8, enforceable in the criminal courts.
People in control of premises
Landlords, managing agents and occupiers, in respect of non-domestic premises used as a workplace.
Designers and suppliers
Those who design, manufacture, import or supply articles and substances for use at work.
Directors and managers
Personally, under section 37, where an offence involved their consent, connivance or neglect.
In practice the Act’s general duties apply in Great Britain — England, Scotland and Wales — and are enforced by the HSE and local authorities. Northern Ireland has its own equivalent provisions under the Health and Safety at Work (Northern Ireland) Order 1978, enforced by HSENI. The duties are broadly the same, but the detail occasionally differs, so check with HSENI if you operate there.
The Key Sections
The Act runs to more than eighty sections, but a small handful account for almost everything an employer or manager encounters in practice.
| Section | Subject | What it says |
|---|---|---|
| 2(1) | The general duty | Employers must ensure, so far as is reasonably practicable, the health, safety and welfare at work of all employees. Everything else flows from this. |
| 2(2) | What that covers | Safe plant and systems of work; safe use, handling, storage and transport of articles and substances; information, instruction, training and supervision; safe premises and access; a safe working environment with adequate welfare facilities. |
| 2(3) | Written policy | A written health and safety policy where five or more people are employed, brought to employees’ attention. |
| 2(6)–(7) | Consultation | Duty to consult safety representatives, and to establish a safety committee if asked. |
| 3 | Non-employees | Employers and the self-employed must not expose people who aren’t their employees to risk — contractors, visitors, volunteers, the public. |
| 4 | Premises | Duties on those in control of non-domestic premises used as a place of work. |
| 6 | Articles and substances | Duties on designers, manufacturers, importers and suppliers of equipment and materials used at work. |
| 7 | Employee duties | Take reasonable care for your own safety and that of others affected by your acts or omissions, and co-operate with your employer. |
| 8 | Interference | No person shall intentionally or recklessly interfere with or misuse anything provided in the interests of health and safety. Applies to everyone, not just employees. |
| 9 | No charging | Employers cannot charge employees for anything done or provided to meet a statutory health and safety requirement. PPE included. |
| 20 | Inspector powers | Entry, examination, taking measurements, photographs and samples, requiring documents, and requiring people to answer questions. Statements given can be used in evidence. |
| 21 | Improvement notice | Requires a contravention to be put right within a stated period — not less than 21 days. |
| 22 | Prohibition notice | Stops an activity involving a risk of serious personal injury. Can take effect immediately. |
| 37 | Personal liability | Directors and senior managers can be prosecuted personally where an offence was committed with their consent, connivance or neglect — connivance meaning they knew and allowed it to continue. |
| 40 | Burden of proof | Where a duty is qualified by “reasonably practicable”, it is for the defendant to prove it was not reasonably practicable to do more. The burden sits with you, not the prosecution. |
“So far as is reasonably practicable”
The phrase that qualifies most duties in the Act. It means weighing the level of risk against the time, money and effort needed to reduce it. Where risk is serious, very little counts as disproportionate; where it is trivial, an expensive control may not be required.
Section 40 is the sting. If you are prosecuted, the burden of showing it was not reasonably practicable to do more falls on you — a reversal of the usual position in criminal law, and the reason documented risk assessments matter so much in practice.
How the Act Is Enforced
The HSE enforces the Act in higher-risk sectors — construction, manufacturing, agriculture, healthcare. Local authority environmental health officers enforce it in retail, offices, hospitality, warehousing and leisure. The powers are the same either way.
Enforcement notices
| Improvement notice (s21) | Prohibition notice (s22) | |
|---|---|---|
| Trigger | A contravention is happening, or has happened and is likely to recur. | An activity involves a risk of serious personal injury. |
| Effect | Work continues; you must put the problem right by a stated date. | The activity stops, often immediately, until remedied. |
| Time to comply | Not less than 21 days. | Can be immediate. |
| Appeal | To an employment tribunal within 21 days. The appeal suspends the notice. | To an employment tribunal within 21 days. The appeal does not suspend the notice unless the tribunal directs it. |
Notices that stand are published on the HSE’s public register. Failing to comply with either is a criminal offence in its own right, separate from whatever prompted the notice.
Prosecution and penalties
Breaches are criminal offences. Sentencing follows the Sentencing Council’s definitive guideline, which sets penalties by reference to culpability, the seriousness of the harm risked, and the organisation’s turnover. The most serious offences carry unlimited fines, and imprisonment is available for individuals.
There is also Fee for Intervention. Where the HSE finds a material breach, it recovers the cost of its own investigation time from the duty holder — a charge that applies whether or not any prosecution follows.
Where a death results from a gross breach of a duty of care by senior management, an organisation may also face a charge under separate legislation — see corporate manslaughter.
The Regulations Made Under the Act
The Act itself rarely tells you what to do in specific terms. That work is done by regulations made under it, and this is where most day-to-day obligations actually live.
A common misunderstanding is worth clearing up here. Risk assessment is not, strictly, a HASAWA duty. The explicit requirement to carry out a suitable and sufficient assessment comes from regulation 3 of the Management of Health and Safety at Work Regulations 1999. It is how you demonstrate compliance with sections 2 and 3 of the Act, which is why the two are so often conflated — but if you are asked where the duty sits, the answer is the Management Regulations. See risk assessment guidance.
Management of Health and Safety at Work Regulations 1999
Risk assessment, competent persons, health surveillance, emergency procedures. See risk assessment guidance.
COSHH 2002
Substances hazardous to health — assessment, control and monitoring. See COSHH guidance.
Work at Height Regulations 2005
Any height where a fall could cause injury, including ladders. See working at height guidance.
CDM 2015
Construction projects — client, designer and contractor duties. See CDM guidance.
PPE at Work Regulations 1992 (amended 2022)
Duties now extend to casual and agency workers. See PPE guidance.
RIDDOR 2013
Reporting injuries, diseases and dangerous occurrences to the enforcing authority. See RIDDOR guidance.
DSE Regulations 1992
Workstation assessments, including for homeworkers. See DSE guidance.
Manual Handling Operations Regulations 1992
Avoid, assess and reduce the risk of hazardous manual handling. See manual handling guidance.
Fire safety is the notable exception. It sits outside this structure, under the Regulatory Reform (Fire Safety) Order 2005 in England and Wales, with separate legislation in Scotland and Northern Ireland.
Training That Covers the Act
Section 2(2)(c) makes information, instruction, training and supervision a legal duty, not a nice-to-have — and regulation 13 of the Management Regulations repeats it. What level you need depends on the role.
| Who | Usual route |
|---|---|
| Everyone, as a baseline | IOSH Working Safely or a general health and safety course. |
| Managers and supervisors | IOSH Managing Safely — three days in the classroom, covering the legal framework, risk assessment and incident investigation. |
| Anyone in a formal H&S role | NEBOSH General Certificate, which examines the Act directly. |
| Construction supervisors | SSSTS, or SMSTS for site managers. See also construction safety courses. |
| Construction specialists | NEBOSH Construction Certificate or the NEBOSH Fire Certificate. |
| Environmental duties alongside | Environmental management and awareness training. |
Remember section 9: you cannot pass the cost of legally required training on to the employee.

Frequently Asked Questions
What does HASAWA stand for?
The Health and Safety at Work etc. Act 1974. You will also see it abbreviated as HSWA, HASAW or the HSW Act — all the same statute.
What does the Health and Safety at Work Act cover?
It sets general duties for protecting people from harm arising out of work: employers to employees (section 2), employers and the self-employed to everyone else affected (section 3), those in control of premises (section 4), suppliers of work equipment (section 6), and employees themselves (sections 7 and 8). It also creates the HSE, gives inspectors their powers, and provides the framework under which all health and safety regulations are made.
Is HASAWA still in force?
Yes. It has been amended in places over fifty years, but the general duties in sections 2 to 9 are essentially unchanged from 1974 and remain the foundation of UK workplace health and safety law.
Why is there an “etc.” in the title?
Because the Act does more than regulate work. Its long title also covers protecting people who are not at work, controlling the keeping and use of dangerous substances, controlling certain emissions into the atmosphere, the employment medical advisory service, and amendments to building regulations. The “etc.” stands in for all of that, and it is part of the formal name rather than an abbreviation of it.
Does the Act apply to Northern Ireland?
Not for the general duties. Those apply in Great Britain — England, Scotland and Wales. Northern Ireland has its own equivalent provisions under the Health and Safety at Work (Northern Ireland) Order 1978, enforced by HSENI rather than the HSE. The duties are broadly the same but the detail occasionally differs.
Are risk assessments required by HASAWA?
Indirectly. The explicit duty to carry out a suitable and sufficient risk assessment comes from regulation 3 of the Management of Health and Safety at Work Regulations 1999, made under the Act. Risk assessment is how you demonstrate you have met the section 2 and 3 duties, which is why the two get conflated. Significant findings must be recorded once you employ five or more people. See how to conduct a risk assessment.
Can I be prosecuted personally as a director?
Yes, under section 37, where an offence by the organisation was committed with your consent or connivance, or was attributable to your neglect. Connivance means you knew about it and allowed it to continue. Employees can also be prosecuted under sections 7 and 8 in their own right.
What’s the difference between an improvement notice and a prohibition notice?
An improvement notice (section 21) says something is wrong and gives you at least 21 days to fix it — work carries on meanwhile. A prohibition notice (section 22) stops the activity, often immediately, because it involves a risk of serious personal injury. Both can be appealed to an employment tribunal within 21 days, but only an improvement notice appeal suspends the notice in the meantime.
