outward
Which factor is likely to affect the speed with which a steel structural member fails under
fire conditions? - ANSWER-Size
How does reinforced concrete react to exposure to fire? - ANSWER-It performs well but
can lose strength through spalling
Which type of building material is used to protect other materials because its moisture
content gives it excellent heat resistance? - ANSWER-Gypsum wallboard
What is a concern about lath and plaster during a fire? - ANSWER-Conceals hidden fire
and adds fuel to the fire
Which statement best describes how glass will react under fire conditions? - ANSWER-

- ANSWER-Bar screw jack
Which rescue tool is the least stable of jacks and is prone to fail under heavy loads? -
ANSWER-Ratchet-lever jack
What is the purpose of a tensioned buttress system? - ANSWER-Stabilize vehicles
resting on their sides or roofs
Which is a characteristic of plastic cribbing? - ANSWER-Resist contamination from fuel,
oil, or other substances
Which rescue tool is typically used when objects must be pushed further than the
maximum opening distance of hydraulic spreaders? - ANSWER-Extension rams
