Health & Safety Legislation Explained

UK, EU, US, Canada, Australia & Other Key Markets

Health & Safety legislation exists to prevent harm and ill health at work, setting out employer responsibilities, worker duties, and penalties for non-compliance under health and safety law.

Across different countries, the legal systems differ, but the core idea remains the same: employers must proactively manage risk, protect workers and others, and demonstrate compliance.

Because UK Health & Safety law is widely regarded as one of the most mature and risk-based frameworks, many organisations use it as a benchmark when designing global compliance systems.

What Is Health & Safety Legislation?

Health & Safety legislation sets out:

  • Who must manage risk
  • What duties they have
  • How risk must be assessed and controlled
  • What training and information must be provided
  • How incidents must be reported

Across jurisdictions, this can include:

  • Employer duties
  • Employee duties
  • Competent person requirements
  • Training and supervision
  • Recordkeeping and reporting
United Kingdom (UK)

Primary Legislation

Health and Safety at Work etc. Act 1974 – the fundamental piece of UK legislation setting out general duties on employers and workers alike.

Health and Safety Executive

Employee Thresholds

  • 1+ employees → general statutory duties apply
  • 5+ employees → written Health & Safety policy required
  • A competent person is required regardless of size

Key Requirements

  • Suitable and sufficient risk assessments
  • Appointment of a competent person
  • Health and safety policy (5+ employees must be in writing)
  • Display the health and safety law poster or provide leaflet
  • Safe systems of work
  • Information, training and supervision
  • Fire risk assessment (Fire Safety Order)
  • Incident reporting (RIDDOR — Reporting of Injuries, Diseases and Dangerous Occurrences)

Secondary Regulations (Common Examples)

  • Management of Health and Safety at Work Regulations 1999 (MHSWR)
  • Regulatory Reform (Fire Safety) Order 2005
  • Electricity at Work Regulations 1989
  • Workplace (Health, Safety and Welfare) Regulations 1992
  • Manual Handling Operations Regulations 1992
  • PUWER 1998

  • DSE Regulations 1992
  • Noise at Work Regulations 2005
  • PPE at Work Regulations 1992
  • Health and Safety Information for Employees Regulations 1989

These regulations support the core duties and address specific hazards.

Why the UK Is Seen as the Leading Standard

  • Risk-based rather than prescriptive
  • Applies equally to offices, remote work, and high-risk sectors
  • Strong enforcement and case law history
  • Frequently used as the baseline model for global H&S frameworks

Many international organisations adopt UK-style systems to ensure consistency across borders.

European Union (EU – Central & Western Europe)

Framework Law:

EU Framework Directive 89/391/EEC

Implemented through national legislation in each member state.

General Applicability

  • Applies from 1 employee
  • Risk assessment is mandatory
  • Worker consultation and training required
  • Use of competent persons required

Common EU Requirements

  • Written risk assessment documentation
  • Preventive and protective measures
  • Training and information for employees
  • Consultation with workers or representatives
  • Periodic review of risk controls

Country-Specific Notes

Germany

  • Law: Arbeitsschutzgesetz (ArbSchG)
  • Applies from 1 employee
  • Requires risk assessments and preventive measures
  • Mandatory occupational health support for many employers

France

  • Law: Labour Code (Code du Travail)
  • Applies from 1 employee
  • Mandatory DUERP risk assessment document
  • Strong enforcement focus on documentation

Netherlands

  • Law: Working Conditions Act (Arbowet)
  • Applies from 1 employee
  • Mandatory risk inventory (RI&E)
  • Special focus on psychosocial risk and remote work

Note: EU compliance does not automatically align with UK law, but UK systems are often used as a strong baseline and adapted locally.

United States (USA)

Primary Law: Occupational Safety and Health Act of 1970 (OSHA)

Applies to: Most private-sector employers.

1+ employees → General Duty Clause applies

10+ employees → injury and illness recordkeeping (with some exemptions)

Provide a workplace free from recognised hazards

Comply with applicable OSHA standards

Maintain OSHA injury and illness logs

Provide training where required by standards

Key Difference vs UK

Many US tech and SaaS businesses adopt UK-style risk assessments voluntarily to strengthen governance.

Canada

Legal Structure: Federal + Provincial / Territorial legislation

1+ employees → duties apply

Thresholds vary by province for joint safety committees

Identify and control workplace hazards

Provide training and supervision

Establish emergency procedures

Report serious incidents

In some provinces: joint health & safety committees or representatives

Canadian systems align closely with UK and EU risk-based approaches, making UK frameworks relatively easy to adapt.
