Hazardous materials releases that involve excessive noise levels only cause psychological stress to personnel in specialized protective clothing.

Hazardous materials releases that involve excessive noise levels only cause psychological stress to personnel in specialized protective clothing.

• A. True
• B. False
• C. They cause only physical stress
• D. No effect

Answer: (B)

Noise during hazardous materials releases creates both psychological and physical stress. Excessive levels can mask alarms and radio messages, blur speech, and raise cognitive load, leading to poorer decision-making and slower reactions. At the same time, it can cause physical effects such as hearing damage, headaches, fatigue, and increased heart rate, all of which are worsened when wearing protective clothing that restricts heat dissipation. So the idea that noise only causes psychological stress is not accurate.
