15

Tower ladders and aerial ladders should not be tied up stretching lines up them. TRUE OR FALSE

TRUE

16

Hose lines should not be operated into VENTILATION holes from the roof as this decreases ventilation and nullifies the action of lines operating on the top floor. What are the 3 operations a line on the roof should be used for?

Prevent fire from extending past a trench
Protect exposures
Extinguish fire that cannot from below, such as fire in a cornice

As a general rule outside streams should not be directed into occupied buildings. OCCUPANTS should be removed first. However, in some cases, life safety or fire conditions may require that outside streams be used in occupied buildings. What are they?

Protect people of fire escapes
Heavy fire in a store

Only the IC can order the use of outside streams This may be the officer arriving 1st!

A charged hose line MUST be ready before the store is ventilated

Cockloft fires on OLT's are much smaller than in NLT;s and are therefore not much of a problem. Usually these fires are extinguished via?

From below AFTER an adequate vent hole is cut over the fire

25

A hoseline should be stretched to the nearest point from which water can be directed onto fire in the shaft. For fires in rooms in the vicinity of a shaft, after the fire has been______, the line should be operated up the shaft to ______ the fire and cool the shaft.
