What are the three general types of toxic hazards encountered in an aviation environment?

• A. Physical, Chemical, Biological
• B. Mechanical, Thermal, Electrical
• C. Psychological, Social, Economic
• D. Radiological, Nuclear, Biological

Answer: (A)

Toxic hazards in aviation fall into three broad categories: chemical, biological, and physical. Chemical hazards come from exposure to toxic substances like fuels, solvents, deicing fluids, and cleaning agents that can affect the body if inhaled, absorbed, or ingested. Biological hazards involve exposure to organisms or biological toxins, such as microbes or bioaerosols from water systems, passengers, or contaminated surfaces. Physical hazards relate to energy forms or environmental conditions that can harm you through their physical effects—think extreme temperatures, high noise levels, vibration, or radiation at altitude. Together, these three categories cover the main ways substances or conditions can cause harm in an aviation setting. The other options mix categories that aren’t as inclusive or label hazards that aren’t typically grouped under these broad toxic hazard types.
