An Integrated Method for Fire Risk Assessment in Residential Buildings

Table 3

Classification of the building fire risk level.

Fire risk level	Risk interval	Risk description and measures
Very low	(0.00, 0.06]	Risks are negligible.
Low	(0.06, 0.25]	Risks are acceptable, but if cost-effectiveness is reasonable, measures can be taken to reduce risks.
Moderate	(0.25, 0.44]	Risks are tolerable and, if feasible, measures must be taken to reduce them.
High	(0.44, 0.72]	Measures must be taken to reduce risks.
Very high	(0.72, 1.00]	Risk is unacceptable. Measures must be taken to reduce the risk and control it effectively.
