FIRE ALARMS
READ EACH SCENARIO, THEN ANSWER THE QUESTION IN DETAIL.
Construction has just begun on a local plot where a major fast-food chain is building a new, wooden building. What dangers may this present?
Resturants of wood construction usually include trusses in their roof structures. Potential hazards include large areas of void, large dead loads, hidden fires, and quick collapse.
FIRE ALARMS
READ EACH SCENARIO, THEN ANSWER THE QUESTION IN DETAIL.
A house built in 1938 is on fire. What type of construction is this building most likely to be, and what hazards coud this construction present to firefighters?
Houses built around that time generally were baloon-frame. This house may not have any firestopping. Firefighters should anticipate that the wood may be damaged in some areas and that there may be voids. Additionally, sprinklers are probably not present or may not be effective. Basement fires may allow the fire to travel through the building quickly.
