Small-scale biomass power plants (less than 10 MW) pose a high risk of fire. A few comprehensive and systematic studies on fire risk assessment of power plants have been found, and it has been unclear what fire safety attributes need to be considered to constitute an acceptable safety level. This paper presents a proposed fire risk assessment method using a scoring system in small-scale biomass power plants (FRS-SBP). 34 fire safety attributes are classified into four criteria: building characteristics; fire safety systems; fire safety management; and operations and maintenance to identify fire safety performance characteristics. Pairwise comparisons are performed in Analytic Hierarchy Process (AHP) for weighting different fire risk attributes and creating a unique checklist provided by professional experts. This study demonstrates the successful implementation of the proposed FRS-SBP in a case study of two biomass power plants. Calculation results indicate that the fire risk of small-scale biomass power plants is high, and the accuracy of this study is considered reliable. The fire safety systems criterion has the lowest final scores and needs immediate improvements. Findings from this study can serve as a practical guide for biomass power plants and apply to other industrial sectors for enhancing fire safety performance.
