Why should firefighters exit the IDLH before their low-pressure alarm activates? (436) [4.3.5, 4.3.9] The remaining air is insufficient to exit even if no emergencies occur. The remaining air is an average, not specific to each firefighter, so it may be insufficient to exit from both short and long distances. The remaining air is insufficient to exit from deep inside a large structure and does not take into account emergencies that may be encountered. Hearing the alarm may cause panic, which will speed up air consumption.
The remaining air is insufficient to exit from deep inside a large structure and does not take into account emergencies that may be encountered.
Why is it dangerous to work below the hot gas layer without attempting to cool it? (676) [4.3.10] The hot gas layer can break open windows, creating ventilation issues. The hotter the gas layer is, the more toxic the fumes are. The smoke contains fuel, and it may ignite at any time. The hot gas layer will continue to raise and cause damage to the ceiling and floors above.
The smoke contains fuel, and it may ignite at any time.
Which statement describes a fire in the incipient stage? (146) [4.3.11] The temperature is only slightly above ambient in areas that the fire, plume, and ceiling jet directly affect.

The fire has grown large enough for compartment configuration and amount of ventilation to influence it.
The temperature is only slightly above ambient in areas that the fire, plume, and ceiling jet directly affect.

What occurs during flashover? (154) [4.3.11] The volume of burning gases can increase to fill the room's entire volume and extend out of any openings from the room. The heat release rate of the fire will reach its peak. Flames propagate through the hot gas layer or across the ceiling. The compartment will fill with black smoke and slowly cooling fuel gases; the compartment will show no visible flames.
The volume of burning gases can increase to fill the room's entire volume and extend out of any openings from the room.
What may occur if water is added to a burning liquid that is less dense than water? (139) [4.3.10] The water may disperse the burning liquid instead of extinguishing it. The fuel's rate of vaporization will decrease due to the increased water pressure. The liquid fuel may vaporize much more rapidly as it draws thermal energy from the water.
