The use and storage of hazardous materials within a structure can subject process operations to many regulatory and permitting requirements. One of the most overlooked and misunderstood requirements is how hazardous material utilization affects the International Building Code (IBC) and International Fire Code (IPC) occupancy classification of a facility and determines the allowable design and layout features of the structure. Occupancy classification can present significant operational issues when an existing facility plans to increase or change the type or quantity of hazardous materials being used, including the use and storage of combustible dust. The model building codes in the U.S., most commonly the International Code Council Series, establish strict requirements for the use of hazardous materials through the occupancy classification process. The intent is to set minimum requirements to ensure occupant and emergency responder safety and protect surrounding property ...e.g., minimize the spread of a fire). Since these codes are generally adopted by local and state governments, the model codes serve as legal requirements.
