In firefighting terminology, what is an 'exposure'?
Answer: A structure or area adjacent to the fire that may be endangered by heat or flame spread
An exposure is any structure, vehicle, or property adjacent to the fire that is at risk of ignition due to radiated heat or direct flame contact.
What is the primary danger of carbon monoxide (CO) in a structure fire?
Answer: It is colorless and odorless, making it undetectable without instruments
Carbon monoxide is colorless and odorless, so victims can inhale lethal concentrations without any sensory warning.
Which nozzle pattern is BEST for cooling a superheated ceiling and slowing flashover development?
Answer: Wide fog pattern
A wide fog pattern directed at the ceiling rapidly converts water to steam, absorbing large amounts of heat and cooling the upper gas layer.
What does the 'two-in, two-out' rule require at a structure fire?
Answer: When firefighters enter an IDLH atmosphere, at least two must remain outside ready to assist
The OSHA two-in, two-out rule mandates that at least two firefighters remain outside in standby rescue mode whenever crews are operating inside an IDLH atmosphere.
What is a 'primary search' in firefighting operations?
Answer: A rapid, systematic sweep of a burning structure to locate and rescue victims before fire is controlled
A primary search is a fast, systematic search conducted in a burning structure to locate and remove victims as quickly as possible.
Heat transfer through the movement of heated gases or liquids is called:
Answer: Convection
Convection is the transfer of heat through the physical movement of heated fluids (gases or liquids) from one location to another.
