Using either hand
A key, tool, special knowledge, or effort (Correct answer)

They require a key to exit (Correct answer)
They wear out faster
They cannot be rekeyed
They cannot be master keyed

Correct answer: They require a key to exit

Needing a key to exit violates egress requirements and traps occupants in an emergency.

Remove the label for access
Confirm the work stays within the door label's allowable preparations and uses listed hardware (Correct answer)

Paint over the label

Correct answer: Confirm the work stays within the door label's allowable preparations and uses listed hardware

Unapproved cutting or non-listed hardware can void the fire rating.

Deadbolt only, thrown by key
Positive latching that engages automatically on closing (Correct answer)
A hook bolt thumbturn
A magnet-only hold

Fire doors must self-latch every time they close, so a key-thrown deadbolt alone is not acceptable.

A stop-arm only
A listed self-closing device such as a closer (Correct answer)
A kick plate
A spring hinge on a wooden frame only

Deadbolts
Safes
Padlocks

Correct answer: Panic hardware

UL 305 covers panic hardware, while fire exit hardware also meets UL 10C fire testing.

Question 20: Which of the following is true about fire door labels?

They may be removed during painting
They must remain legible and not be painted over (Correct answer)
They apply only to wood doors
They are optional on rated openings

Correct answer: They must remain legible and not be painted over

Labels identify the rating and listing, so they must remain intact and visible.

Question 21: Fire door assemblies are tested to UL 10C, which evaluates doors under:

Negative pressure only
Positive pressure fire exposure (Correct answer)
Earthquake motion
Sound transmission

Correct answer: Positive pressure fire exposure
