What is Occupational Health and Safety (OHS)?


What is Occupational Health and Safety (OHS)?
Occupational Health and Safety (OHS) is the practice of protecting people in the workplace by reducing the risk of accidents, injuries, and work-related ill health. It focuses on identifying workplace hazards, managing risks, and implementing safe systems of work to create healthier and safer working environments. In the UK, employers have a legal duty to provide a safe place of work and take actionable steps to protect the health, safety, and welfare of employees and anyone who may be affected by their work activities.
Understanding Occupational Health and Safety
Occupational Health and Safety is at the heart of every safe and successful workplace. From high-risk industries to IT hubs, OHS has transformed from protecting workers against physical hazards to supporting mental wellbeing, ergonomics, and sustainable workplace practices.
Whether you are an employer, employee, or aspiring health and safety professional, this guide covers the essentials of Occupational Health and Safety—including its organizational importance, legal frameworks, workplace applications, and the exact qualifications needed to accelerate your career.
Difference Between Occupational Health and Occupational Safety with examples
| Occupational Health | Occupational Safety |

| Focuses on employees’ physical, mental, and social wellbeing. | Focuses on preventing workplace accidents and injuries. |
| Aims to prevent work-related illnesses and occupational diseases. | Aims to eliminate or control workplace hazards. |
| Covers health surveillance, occupational hygiene, and employee wellbeing. | Covers safe systems of work, equipment safety, and hazard control. |
| Addresses long-term health risks, such as stress, noise, and chemical exposure. | Addresses immediate risks, such as slips, falls, machinery, fire, and electrical hazards. |
Example for Occupational Health and Safety

Importance of Occupational Health and Safety (OHS)
Occupational Health and Safety is a key driver of resilient, high-performing organizations. As workplaces evolve with new technologies, hybrid working, and changing employee expectations, businesses must proactively protect both physical and mental wellbeing.
The recent Health and Safety Executive (HSE) statistics show that 1.9 million workers in Great Britain experienced work-related ill health and 680,000 sustained a workplace injury during 2024/25. These numbers highlight exactly why Occupational Health and Safety (OHS) must remain a priority. Investing in robust safety measures directly supports employee wellbeing, maintains business continuity, and improves long-term organizational performance.
Evolution of Occupational Health and Safety (OHS) Legislation
Occupational Health and Safety legislation has evolved over the past two centuries to improve workplace safety, protect workers, and define employer responsibilities. Today, it provides the legal framework for creating safer and healthier workplaces across Great Britain.

Early Workplace Safety Reform
The Industrial Revolution that took place in the UK resulted in rapid economic growth as well as exposing employees to unsafe working conditions. To address these systemic risks, the government introduced a series of laws to improve workplace safety and worker welfare.
-
The Health and Morals of Apprentices Act 1802: The UK’s first major step toward worker welfare, introducing basic protections for young apprentices working in mills and textile factories.
The Factory Act 1833: A massive regulatory milestone that established the first-ever factory inspections, ensuring businesses were actually held accountable to the law.
The Employer’s Liability Act 1880: A vital legal shift that gave injured employees the formal right to seek compensation if an accident was caused by employer negligence.
Although these reforms represented significant progress, they applied mainly to factories and certain industries.
The Health and Safety at Work etc. Act 1974
A major turning point came with the introduction of the Health and Safety at Work etc. Act 1974, which established the primary legal framework for workplace health and safety in Great Britain. The Act also led to the creation of the Health and Safety Executive (HSE), the national regulator responsible for enforcing health and safety law.
Key OHS Health and Safety Legislation
| Legislation | Purpose |
|---|---|
| Health and Safety at Work etc. Act 1974 | Provides the primary legal framework for workplace health and safety in Great Britain. |
| Workplace (Health, Safety and Welfare) Regulations 1992 | Sets minimum standards for workplace facilities, including ventilation, lighting, temperature, cleanliness, maintenance, and employee welfare. |
| Management of Health and Safety at Work Regulations 1999 | Sets minimum standards for workplace facilities, including ventilation, lighting, temperature, cleanliness, maintenance, and employee welfare. |

Examples Across Different Industries
Every workplace has its own health and safety risks, depending on the industry, work environment, and activities being carried out. Recognizing these hazards early is the first step towards preventing injuries, reducing work-related ill health, and creating a safer workplace. Regular risk assessments help organizations identify potential risks and implement appropriate control measures.
| Industry | Common Occupational Health and Safety Issues |
|---|---|
| Construction | Working at height, falling objects, heavy machinery, manual handling, noise, dust exposure. |
| Manufacturing | Machinery hazards, chemical exposure, repetitive tasks, fire and electrical risks. |
| Oil and Gas | Confined spaces, hazardous substances, explosions, process safety, high-risk operations. |
| Healthcare | Infection control, sharps injuries, hazardous drugs, patient handling, workplace violence. |
| Warehousing & Logistics | Forklift operations, manual handling, vehicle movements, slips, trips, and falls. |
| Office & Corporate | Poor ergonomics, display screen equipment (DSE), stress, mental wellbeing, sedentary work. |
| Education | Fire safety, laboratory hazards, manual handling, safeguarding, stress management. |
| Hospitality & Retail | Slips and trips, hot surfaces, manual handling, workplace violence, food safety. |
Role of Risk Assessment in OHS
Risk assessment is an essential component of occupational health and safety (OHS). It enables organizations to identify workplace hazards, assess risk levels and implement appropriate control measures before harm occurs. Regular risk assessments not only protect employees but also improve legal compliance, operational efficiency, and overall workplace safety.
