What is the maximum floor area per unit of A for extra hazard occupancy?

In the context of fire safety regulations, extra hazard occupancies are defined as those spaces where the potential for fire is significantly increased due to the presence of flammable materials, processes involving combustion, or the storage of hazardous substances.

For extra hazard occupancy, the maximum floor area per unit of A, which refers to the area that can be effectively protected by a portable fire extinguisher within this type of environment, is set at 1000 square feet. This guideline ensures that the risks associated with higher fire loads can be addressed effectively through the appropriate placement and availability of fire extinguishers, allowing for a quicker response and better management of potential fire incidents.

Understanding the area limitations is crucial for compliance with fire safety standards and ensuring adequate fire protection measures within potentially hazardous settings. The other options represent larger areas, which do not align with the stringent safety requirements mandated for extra hazard occupancies.
