A fire protection specialist is reviewing a chemical plant that stores oxidizers. Which statement BEST describes why oxidizers increase fire hazard?
Answer: Oxidizers supply additional oxygen, accelerating combustion and potentially enabling burning without atmospheric oxygen
Oxidizers release oxygen during decomposition, which can sustain or accelerate combustion even in oxygen-depleted environments, significantly increasing fire severity.
According to NFPA 652, which document must be completed for facilities that handle combustible dusts to determine whether a dust hazard exists?
Answer: Dust Hazard Analysis (DHA)
NFPA 652 requires a Dust Hazard Analysis (DHA) to identify, evaluate, and document fire, flash fire, and explosion hazards associated with combustible dust.
A fire safety specialist is evaluating a spray paint booth. The MOST appropriate ventilation rate to maintain flammable vapor concentration below hazardous levels is:
Answer: Sufficient to keep vapor concentration below 25% of the LFL
NFPA 33 requires spray booth ventilation to maintain flammable vapor concentrations below 25% of the Lower Flammable Limit (LFL) as a safety margin.
When assessing fire hazards in a cold storage facility, which factor presents the GREATEST ignition risk unique to these environments?
Answer: Ammonia refrigerant leaks creating a flammable atmosphere
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.
A risk matrix combines two primary variables to prioritize fire hazards. These two variables are:
Answer: Likelihood of occurrence and severity of consequences
A risk matrix evaluates hazards by plotting likelihood (probability) against consequence severity to determine overall risk priority.
In the context of fire hazard management, 'inherently safer design' (ISD) is best exemplified by which action?
Answer: Substituting a flammable solvent with a non-flammable alternative
Inherently safer design eliminates the hazard at its source; substituting a flammable solvent with a non-flammable one removes the fire hazard entirely rather than controlling it.
Which NFPA standard specifically governs the storage, use, and handling of liquefied petroleum gases (LPG) to minimize fire and explosion hazards?
Answer: NFPA 58
NFPA 58, the Liquefied Petroleum Gas Code, governs the storage, handling, transportation, and use of LP-Gas to minimize associated fire and explosion hazards.
