What is a key factor in distinguishing between different types of occupancy?

The function of the space is a key factor in distinguishing between different types of occupancy. This pertains to understanding how a building or area is used, as different functions have varying risks, hazards, and requirements for safety and fire protection. For instance, a residential occupancy, such as a single-family home, has very different characteristics and needs compared to a commercial occupancy like a retail store or an industrial facility.

The occupancy type determines not only the building codes and regulations that apply but also influences fire protection strategies, emergency response plans, and the placement of firefighting resources. Recognizing the purpose of a space allows fire officers to make informed decisions on fire prevention, response tactics, and overall safety considerations tailored to that specific environment.

While the size of the building, the age of the occupancy, and the presence of fire suppression systems are all relevant elements in the context of fire safety and management, they do not inherently define the classification of an occupancy. The primary factor in the classification hinges on its function, which in turn dictates the associated fire risks and safety protocols.
