Question 2

Which investigative approach does NFPA 921 require for determining fire cause?

Accepted Answer

The scientific method, including hypothesis formation and testing

Answer

NFPA 921 requires using the scientific method — forming and testing hypotheses — to objectively determine fire cause.

Question 3

What does 'fire load' refer to in fire inspection and investigation?

Accepted Answer

The total amount of combustible material in a given space

Answer

Fire load is the total quantity of combustible materials in a space, expressed in BTUs per square foot, affecting potential fire severity.

Question 4

A 'V-pattern' on a wall typically indicates what about fire origin?

Accepted Answer

The point of origin is likely located below the base of the V

Answer

A V-pattern points toward the area of fire origin below its base, as flames and heat naturally spread upward and outward from the source.

Low burn indicators below normal ignition height may suggest accelerant use or deliberate fire setting, as fires naturally burn upward.
