What are the four primary categories of workplace hazards?

The four primary categories of workplace hazards include physical, chemical, biological, and ergonomic hazards.

Physical hazards encompass various environmental factors that can cause harm, such as machinery, noise, and slips or falls. Chemical hazards refer to substances that can lead to health issues through exposure, which includes fumes, vapors, and dust. Biological hazards involve organisms or pathogens that pose a risk, such as bacteria, viruses, or mold. Ergonomic hazards arise from workspace design and the physical demands placed on employees, which can lead to musculoskeletal disorders if proper practices are not followed.

This categorization is critical for establishing comprehensive safety and health programs within workplace environments, ensuring workers are protected from a wide range of potential risks. The other options focus on different aspects or combinations of hazards that do not fully encapsulate the recognized and systematic way hazards are addressed within occupational health.
