Which class of fire involves combustible metals such as magnesium, titanium, and sodium?
Answer: Class D
Class D fires involve combustible metals and require specialized dry powder extinguishing agents matched to the specific metal involved.
Which NFPA standard is known as the Life Safety Code, addressing means of egress and fire protection features in buildings?
Answer: NFPA 101
NFPA 101, the Life Safety Code, establishes minimum requirements for egress systems, fire protection features, and emergency lighting in all building types.
In fire safety assessment, the term 'fire load' (fuel load) refers to:
Answer: The total quantity of combustible material present in a given area
Fire load is the total quantity of combustible materials in a space, expressed in BTUs or pounds of wood equivalent per square foot, used to assess potential fire severity.
According to OSHA 29 CFR 1910.38, when must an employer review and update their Fire Prevention Plan?
Answer: Whenever it is no longer adequate or when workplace changes affect fire hazards
OSHA requires the Fire Prevention Plan be reviewed and updated whenever workplace changes affect its adequacy, rather than on a fixed time schedule.
What is the primary function of a designated fire watch following hot work operations?
Answer: To monitor the work area for smoldering fires for at least 30 minutes after hot work ends
Per NFPA 51B, a fire watch must monitor the area for at least 30 minutes after hot work ends because residual heat can cause smoldering fires to develop.
A multipurpose ABC-rated dry chemical fire extinguisher uses which primary extinguishing agent?
Answer: Monoammonium phosphate
ABC multipurpose dry chemical extinguishers use monoammonium phosphate, which melts and coats ordinary combustibles (Class A) while also suppressing Class B and C fires.
In fire development terminology, 'flashover' describes:
Answer: The rapid transition where all combustible surfaces in a room ignite nearly simultaneously
Flashover is the near-simultaneous ignition of all combustible materials in an enclosure, triggered when radiant heat raises room temperatures to approximately 1,100°F (593°C), marking the transition to a fully developed fire.
