What is the proper storage method for flammable liquids in a shelter?
Answer: In an approved flammable storage cabinet, away from ignition sources, in limited quantities
Flammable liquids must be stored in approved flammable storage cabinets (typically yellow, self-closing doors), away from ignition sources, heat, and direct sunlight. Only the quantities needed for immediate use should be kept outside the storage cabinet. Excess quantities require separate storage rooms.
What is the danger of compressed gas cylinders in a fire?
Answer: They can explode or rocket when exposed to heat, and their contents may be toxic or flammable
Compressed gas cylinders exposed to fire heat can BLEVE (boiling liquid expanding vapor explosion), turning the cylinder into a projectile. Additionally, the released gas may be flammable (propane, acetylene), toxic (chlorine, ammonia), or an asphyxiant (nitrogen, carbon dioxide).
What does the blue section of the NFPA 704 diamond indicate?
Answer: Health hazard
The blue section (left side) of the NFPA 704 diamond indicates health hazard severity on a scale of 0-4. A rating of 4 means very short exposure could cause death or major residual injury, while 0 means no hazard beyond that of an ordinary combustible material.
What is the Fireguard's responsibility regarding hazardous material storage in a shelter?
Answer: Ensure hazardous materials are properly stored, labeled, and not accumulating in unauthorized areas during patrols
During patrols, the Fireguard should verify that cleaning chemicals and other hazardous materials are properly stored in designated areas, containers are labeled, no incompatible materials are stored together, and quantities are within approved limits. Unauthorized accumulations must be reported.
What should the Fireguard do if they encounter an unknown chemical spill or leak?
Answer: Treat it as dangerous, evacuate the area, prevent entry, and call 911 without attempting to identify or clean it
An unknown chemical should always be treated as dangerous. The Fireguard should avoid contact, evacuate the area, prevent others from entering, call 911, and wait for trained hazmat responders. Attempting to identify unknown chemicals through touch, smell, or taste can result in serious injury or death.
What is a flammable liquid's flash point?
Answer: The lowest temperature at which the liquid produces enough vapor to ignite when exposed to an ignition source
The flash point is the minimum temperature at which a flammable liquid produces sufficient vapor above its surface to form an ignitable mixture with air. A lower flash point means the liquid is more dangerous because it can ignite at lower temperatures. Gasoline has a flash point of about -45°F.
