FPE Fire Prevention & Hazard Analysis 3

Question 1

The flash point of a flammable liquid is best defined as the:

Accepted Answer

Minimum temperature at which vapor ignites momentarily with an applied ignition source

Answer

Flash point is the minimum liquid temperature at which sufficient vapors are produced to form an ignitable mixture that briefly ignites when exposed to an ignition source.

Question 2

Which NFPA document provides the classification system for flammable and combustible liquids (Class I, II, III)?

Accepted Answer

NFPA 30

Answer

NFPA 30, the Flammable and Combustible Liquids Code, classifies liquids into Class I (flash point < 100°F) and Classes II and III based on flash point thresholds.

Question 3

When conducting a Layer of Protection Analysis (LOPA), the term 'Initiating Event Frequency' refers to:

Accepted Answer

The likelihood per year that the hazard scenario begins without any protective layer acting

Answer

In LOPA, the initiating event frequency is the unmitigated rate at which the loss event scenario is initiated before any independent protection layers reduce the risk.

Question 4

Which fire hazard analysis method uses inductive logic to trace all possible outcomes from a single initiating failure?

Accepted Answer

Event Tree Analysis (ETA)

Answer

Event Tree Analysis is an inductive method that starts from an initiating event and branches forward through success/failure of barriers to determine possible outcomes.

Question 5

Under NFPA 30, an inside liquid storage room for flammable liquids must have a liquid-tight raised sill or ramp at least how high?

Accepted Answer

4 inches (100 mm)

Answer

NFPA 30 requires inside liquid storage rooms to have a liquid-tight raised sill or ramp at least 4 inches (100 mm) high at each door opening to contain spills.
