FPE FPE Passive Fire Protection & Structural Fire Resistance

Question 1

What does a fire resistance rating of '2-hour' for a wall assembly mean according to ASTM E119?

Accepted Answer

The assembly withstands the standard fire test exposure for 2 hours without failure of load, integrity, or insulation criteria

Answer

The wall can withstand flames for 2 hours before igniting

Answer

The wall must be inspected every 2 hours during a fire

Answer

The wall reduces smoke density by 50% over 2 hours

Question 2

Which passive fire protection system subdivides a building into compartments to limit fire and smoke spread?

Accepted Answer

Compartmentalization using fire-rated barriers

Answer

Fire suppression zoning

Answer

Smoke control pressurization

Answer

Intumescent sprinkler baffles

Question 3

What is the primary fire protection function of an intumescent coating applied to structural steel?

Accepted Answer

It expands when heated to form an insulating char that slows heat transfer to the steel

Answer

It cools the steel by absorbing suppression water

Answer

It reflects radiant heat away from the steel surface

Answer

It bonds structural members together during high heat exposure

Question 4

According to IBC, a fire wall must have which structural characteristic that distinguishes it from a fire barrier?

Accepted Answer

It must have structural independence so the collapse of construction on one side does not cause collapse of the wall itself

Answer

It must include automatic suppression on both sides

Answer

It must be constructed of non-combustible concrete only

Answer

It must extend at least 36 inches above the roof

Question 5

What is the maximum allowable gap for a firestop penetration seal around an electrical conduit passing through a 2-hour fire-rated floor assembly?

Accepted Answer

Gaps must be completely filled per the listed firestop system with no allowable gap

Answer

There is no maximum; only the system listing matters

Answer

Up to 1/8 inch is permitted without a listed system

Answer

Up to 1/2 inch if metal conduit is used

Question 6

Which ASTM standard governs fire testing of through-penetration firestop systems in fire-rated walls and floors?

Accepted Answer

ASTM E814

Answer

ASTM E119

Answer

ASTM E1825

Answer

ASTM E2307
