Which of the following are hazards associated with onboard fires?

• A. Alarms going off and passengers panicking
• B. Breathing in smoke, injuries, exposure to chemicals
• C. Loss of oxygen from cabin
• D. Temperature extremes caused by fire

Answer: (B)

Onboard fires create danger primarily from what the fire releases and the heat it generates. The most immediate, pervasive hazards are smoke inhalation, injuries from heat, and exposure to chemicals released by burning materials. Breathing in smoke can injure the lungs and lead to hypoxia, while high temperatures can cause burns and heat-related stress. The chemicals released by burning fabrics, plastics, and other cabin materials can irritate or damage eyes, skin, and the respiratory system. Alarms and passenger panic are real effects of a fire, but they’re reactions to the situation rather than the intrinsic hazards produced by the fire itself. Oxygen depletion can occur in extreme cases, but it isn’t the defining danger in most onboard fires. Temperature extremes happen too, but the combination of smoke, heat, and chemical exposure best represents the core hazards crews must manage.
