Which hazards include fires, dangerous reactions, and explosions?

• A. Chemical Hazards
• B. Biological Hazards
• C. Physical Health Hazards
• D. Ergonomic Hazards

Answer: (C)

Fires, dangerous reactions, and explosions are characteristics of chemical hazards. These hazards arise from the properties of chemicals that can ignite, react violently with other substances, or release energy explosively. Handling and storage controls—like proper labeling, segregation of incompatible materials, grounding and bonding for flammables, and using appropriate PPE—are designed to prevent these outcomes. Biological hazards involve living organisms or their toxins, not chemical reactions or ignition. Physical hazards cover energy forms like radiation, noise, temperature extremes, and pressure that can harm health, while ergonomic hazards relate to how work is designed for the body. Therefore, the category that includes fires, dangerous reactions, and explosions is chemical hazards.
