In a pre-action sprinkler system, water enters the distribution piping when:
Answer: Both a detection system activates AND a sprinkler fuses
A pre-action system requires a 'double interlock': both the detection system must activate and a sprinkler head must open before water discharges.
The 'fire tetrahedron' adds which fourth element to the classic fire triangle?
Answer: Chemical chain reaction
The fire tetrahedron expands the triangle by adding the chemical chain reaction, explaining why halogenated agents can suppress fires by interrupting this reaction.
Which document provides the authority for fire code enforcement and specifies required fire protection features in new construction in most US jurisdictions?
Answer: The International Fire Code (IFC) or adopted model fire code
Most US jurisdictions adopt the IFC or a similar model fire code as the legal authority for fire protection requirements in new and existing buildings.
A building's 'means of egress' consists of how many components under NFPA 101?
Answer: Three: exit access, exit, and exit discharge
NFPA 101 defines means of egress as three distinct components: exit access, exit, and exit discharge.
Sprinkler systems in cold storage or freezer warehouses typically use which system type to prevent water in pipes from freezing?
Answer: Dry pipe system
Dry pipe systems use pressurized air or nitrogen in the piping instead of water, preventing freeze-ups in cold environments until a sprinkler opens.
The density/area design method for sprinkler systems balances which two variables?
Answer: Water application rate (gpm/ft²) and the design area in square feet
The density/area method selects a design based on water application density (gpm/ft²) over a defined design area, ensuring adequate coverage for the hazard.
Under NFPA 10, portable fire extinguishers must be visually inspected at minimum how often?
Answer: Monthly
NFPA 10 requires that portable fire extinguishers be visually inspected at least monthly to confirm they are in their designated location and operable.
