What are the four categories of workplace hazards?

Hazard classification in the workplace is commonly grouped into four broad categories. Biological hazards cover living organisms and their byproducts that can cause illness, such as bacteria, viruses, fungi, and bloodborne pathogens. Chemical hazards include hazardous substances like solvents, acids, gases, fumes, and vapors that can harm health or safety. Ergonomic hazards arise from the design of tasks, tools, and workstations that strain the body—think repetitive motions, awkward postures, heavy lifting, and vibration that can lead to musculoskeletal disorders. Physical hazards involve energy forms that can cause harm, such as noise, extreme temperatures, radiation, electrical risks, and hazards from moving machinery or objects. The set Biological, Chemical, Ergonomic, Physical matches the standard four-category framework used in most workplace safety training and risk assessments. It provides a comprehensive view of the main types of hazards workers face and guides both prevention strategies and inspection focus. Other terms like Environmental, Industrial, or Mechanical aren’t used as the four primary categories in this framework. Environmental hazards are broader and not typically cited as one of the four core groups; Mechanical hazards are usually encompassed within Physical hazards or considered a subset related to machinery.
