CFPS Fire Hazard Management 3

Question 1

A fire protection specialist is reviewing a chemical plant that stores oxidizers. Which statement BEST describes why oxidizers increase fire hazard?

Accepted Answer

Oxidizers supply additional oxygen, accelerating combustion and potentially enabling burning without atmospheric oxygen

Answer

Oxidizers release oxygen during decomposition, which can sustain or accelerate combustion even in oxygen-depleted environments, significantly increasing fire severity.

Question 2

According to NFPA 652, which document must be completed for facilities that handle combustible dusts to determine whether a dust hazard exists?

Accepted Answer

Dust Hazard Analysis (DHA)

Answer

NFPA 652 requires a Dust Hazard Analysis (DHA) to identify, evaluate, and document fire, flash fire, and explosion hazards associated with combustible dust.

Question 3

A fire safety specialist is evaluating a spray paint booth. The MOST appropriate ventilation rate to maintain flammable vapor concentration below hazardous levels is:

Accepted Answer

Sufficient to keep vapor concentration below 25% of the LFL

Answer

NFPA 33 requires spray booth ventilation to maintain flammable vapor concentrations below 25% of the Lower Flammable Limit (LFL) as a safety margin.

Question 4

When assessing fire hazards in a cold storage facility, which factor presents the GREATEST ignition risk unique to these environments?

Accepted Answer

Ammonia refrigerant leaks creating a flammable atmosphere

Answer

Anhydrous ammonia used in refrigeration systems is both toxic and flammable (flammable range 15-28% in air), making refrigerant leaks a critical fire and explosion hazard.

Question 5

A risk matrix combines two primary variables to prioritize fire hazards. These two variables are:

Accepted Answer

Likelihood of occurrence and severity of consequences

Answer

A risk matrix evaluates hazards by plotting likelihood (probability) against consequence severity to determine overall risk priority.
