Hazards are sources or situations with the potential to cause harm to people, property, or the environment. A hazard is not an injury itself; risk combines the likelihood of harm with the severity of its consequences. Hazard identification and risk assessment are central to many safety frameworks and are used to prevent incidents before they occur.

Hazards can be categorized broadly as physical, chemical, biological, ergonomic, psychosocial, electrical, radioactive, or environmental. Physical hazards include noise, heat, and moving machinery. Chemical hazards involve toxic substances or flammable liquids. Biological hazards cover pathogens and toxins. Ergonomic hazards arise from repetitive tasks or poor workstation design. Psychosocial hazards include stress and harassment. Electrical hazards include exposed circuits, and environmental hazards involve extreme weather or poor air quality.

Hazard identification often uses checklists, inspections, reporting systems, and occupational exposure data. Risk assessment evaluates both the likelihood of harm and its potential severity, enabling prioritization. In many systems, a risk matrix or quantitative methods guide those judgments. Controls are then applied to reduce risk.

The hierarchy of controls places elimination or substitution of the hazard at the top, followed by engineering controls, administrative controls, and, finally, personal protective equipment. PPE alone does not remove the hazard but reduces exposure. Effective risk management also relies on training, maintenance, emergency planning, and ongoing monitoring.

Hazards are addressed across workplaces, healthcare, laboratories, construction, and public environments. Public health and safety standards encourage reporting of near misses and incidents to learn and improve, fostering a safety culture that emphasizes proactive prevention.
