JIBC Fire Prevention and Safety 5

Question 1

Which ventilation technique involves cutting openings in the roof directly above the fire to allow heat and smoke to escape vertically?

Accepted Answer

Vertical (vertical/hydraulic) ventilation

Answer

Vertical ventilation removes superheated gases and smoke upward through roof openings, improving visibility and reducing flashover risk for interior crews.

Question 2

A building permit is issued for a new care facility. Under the BC Building Code, which occupancy group would this facility MOST likely fall under?

Accepted Answer

Group B – Detention, Care, or Treatment

Answer

Group B occupancies include facilities where occupants may need assistance evacuating, such as hospitals, nursing homes, and care facilities.

Question 3

When inspecting a paint storage room, an inspector finds no explosion-proof electrical fixtures. The MAIN hazard this creates is:

Accepted Answer

An ignition source for flammable vapors that may accumulate in the space

Answer

Standard electrical fixtures can produce sparks or arcs that ignite flammable vapors; explosion-proof fixtures are required in areas where such vapors may accumulate.

Question 4

The 'fire tetrahedron' adds which fourth element to the traditional fire triangle?

Accepted Answer

Chemical chain reaction

Answer

The fire tetrahedron adds the uninhibited chemical chain reaction to heat, fuel, and oxygen, explaining why some agents (like halon) extinguish fires chemically.

Question 5

Under the Workplace Hazardous Materials Information System (WHMIS 2015), a Safety Data Sheet (SDS) must contain how many sections?

Accepted Answer

16

Answer

WHMIS 2015 (aligned with GHS) requires a standardized 16-section SDS format to ensure consistent hazard communication.
