A hazard is a potential source of harm that can cause damage to health, life, property, or any other interest of value. Hazards can be substances, events, or circumstances that have the potential to cause negative consequences. The terms "hazard" and "risk" are often used interchangeably, but in terms of risk assessment, they have distinct meanings. A hazard is an agent that can cause harm or damage, while risk is the probability that exposure to a hazard will lead to a negative consequence.
In the context of workplace health and safety, a hazard is any source of potential damage, harm, or adverse health effects on something or someone. Hazards can be categorized into various types, such as physical, chemical, biological, ergonomic, and psychosocial. Hazard symbols or warning symbols are easily recognizable symbols designed to warn about hazardous materials, locations, or objects.
Here are some examples of hazards:
- Physical hazards: Noise, vibration, radiation, temperature extremes, and slips, trips, and falls.
- Chemical hazards: Toxic substances, flammable materials, and corrosive substances.
- Biological hazards: Infectious agents, such as bacteria, viruses, and fungi.
- Ergonomic hazards: Poorly designed workstations, repetitive tasks, and manual handling of heavy objects.
- Psychosocial hazards: Workplace violence, stress, and bullying.
