What does 'occupancy' refer to in the context of fire safety?

In the context of fire safety, 'occupancy' specifically refers to the purpose for which a building is used. This concept is crucial because it determines the level of fire risk associated with the activities that occur within the building. Different types of occupancy, such as residential, commercial, industrial, or assembly, have varying fire safety regulations and codes that need to be followed. Understanding occupancy helps fire safety professionals assess hazards, implement appropriate fire prevention measures, and develop effective emergency response plans tailored to the specific risks of that environment. The classification of occupancy influences factors such as the design and construction of fire protection systems, egress routes, and the overall safety strategy for the building.
