Which statement describes a thermal hazard?

• A. Excessive heat or excessive cold
• B. Lack of oxygen
• C. Exposure to a microorganism
• D. Electrical shock

Answer: (A)

Thermal hazards involve extreme temperatures, either very hot or very cold, that can injure people or damage materials. Excessive heat or excessive cold describes this precisely, since it highlights those dangerous temperature extremes and the kinds of harm they can cause—burns, heat illness, frostbite, hypothermia, and potential equipment damage from temperature stress. The other hazards relate to different dangers: lack of oxygen is an asphyxiation risk, exposure to a microorganism is a biological hazard, and electrical shock is an electrical hazard. Recognizing extreme temperatures helps you anticipate the need for temperature control, appropriate PPE, and time limits to prevent harm in hazardous environments.
