Definitions Used In Occupational Health And Safety

Definitions Of Terms Used In Occupational Health And Safety

Understanding basic occupational health and safety definitions is crucial for any meaningful discussion of health and safety issues in the workplace. Here are some important terms and definitions to keep in mind:

1. Health

Health is a state of physical, mental, and social well-being and not merely the absence of disease or infirmity. It is a fundamental human right and a key component of sustainable development. The protection of the health of workers is an essential aspect of occupational health and safety.

Health protection involves identifying and preventing workplace hazards that can lead to illness or injury. This includes ensuring workers have access to safe working conditions, equipment, and procedures and providing education and training on workplace health and safety. It also involves monitoring workers’ health through health surveillance programs and providing medical care and support to workers who become ill or injured on the job.

2. Safety

Safety is the state of being free from harm or danger. In the workplace, safety refers to protecting workers from physical harm, injury, or illness while on the job. It involves identifying and controlling workplace hazards, such as machinery, equipment, chemicals, or environmental conditions, that can cause harm.

Safety is closely related to health, as both are concerned with protecting workers’ physical and mental well-being. While health focuses on preventing illness or injury from workplace processes, materials, or procedures, safety focuses on preventing physical harm or injury from workplace hazards.

3. Welfare

Welfare refers to providing facilities, services, and amenities necessary to maintain workers’ health, well-being, and comfort in the workplace. It includes a range of facilities such as sanitation, restrooms, drinking water, heating, lighting, seating, eating facilities, and first-aid arrangements.

Welfare facilities are important for promoting a healthy and productive workplace. They help ensure that workers are comfortable and safe and can meet their basic needs while on the job. They can also help improve worker morale and job satisfaction, increasing productivity and reducing turnover rates.

4. Hazard

A hazard refers to any potential source or situation in the workplace that has the potential to cause harm, injury, or damage to workers, property, or the environment. Hazards can be physical, chemical, biological, ergonomic, or psychosocial in nature, and they can arise from various sources such as machinery, equipment, materials, processes, work organization, and human behavior. Identifying and managing workplace hazards is important to occupational health and safety to prevent accidents, injuries, illnesses, and fatalities.

5. Risk

Risk refers to the probability or likelihood of harm or injury due to exposure to a hazard. In occupational health and safety, risk is the chance of an adverse event or outcome in the workplace, such as injury, illness, or property damage.

Risk is influenced by various factors, including the type and severity of the hazard, the frequency and duration of exposure, and the vulnerability of the individuals exposed to the hazard. Risk can be quantified or expressed in the probability or frequency of occurrence, the severity of harm, or a combination of both.

Health And Safety Definitions

6. Occupational Health

Occupational Health is a branch of public health that focuses on the identification and prevention of hazards in the workplace that may cause injury, illness, or disease. It is concerned with promoting and maintaining workers’ physical, mental, and social well-being in all occupations.

Occupational health aims to prevent work-related injuries and illnesses by identifying and evaluating workplace hazards and developing strategies to control or eliminate them. This can involve various activities, including risk assessments, health surveillance, and developing policies and procedures to ensure that workplaces are safe and healthy.

7. Accident

An accident is an unplanned or unforeseen event that results in injury, damage, or loss. It is an incident that occurs unexpectedly and can have negative consequences. Accidents can happen anywhere and anytime, including in the workplace, on the road, at home, or in public places.

In occupational health and safety, an accident is an event that results in injury or illness to a worker while on the job. It may also refer to an event that damages property, equipment, or the environment. Accidents can be caused by a variety of factors, such as human error, equipment failure, environmental conditions, or a combination of these factors.

8. Near Miss

A near miss is an incident that could have resulted in an accident or injury but was narrowly avoided. It is an unplanned event that could potentially cause harm but did not result in any harm or damage. Near misses are often considered an important indicator of potential safety hazards and risks in the workplace and can provide valuable information to help prevent future accidents.

The knowledge of near misses is critical in identifying potential safety hazards and preventing future accidents. By investigating and analyzing near misses, employers can identify areas where safety improvements can be made and take corrective action to prevent similar incidents from happening in the future.

9. Dangerous Occurrence

A dangerous occurrence is a specific type of incident defined in the Reporting of Injuries, Diseases, and Dangerous Occurrences Regulations 2013 (RIDDOR). It is an incident that results in a specific, serious outcome, such as a death, major injury, or serious damage to equipment or property.

Under RIDDOR, employers, self-employed individuals, and those in control of work premises have a legal duty to report dangerous occurrences to the relevant enforcing authority, such as the Health and Safety Executive (HSE), as soon as possible after the incident has occurred. Examples of dangerous occurrences that must be reported include:

  • The collapse or failure of load-bearing equipment, such as a crane or scaffolding
  • An explosion or fire causing damage or destruction
  • The uncontrolled release of a harmful substance, such as a toxic gas or biological agent
  • A dangerous incident involving electrical equipment or machinery
