What type of hazard area is an ordinary building or room used as a shop or storage facility?

The classification of an ordinary building or room used as a shop or storage facility as an ordinary hazard area is based on the typical risks associated with such environments. Ordinary hazard areas are those spaces where materials with moderate hazards are stored or used, which include everyday items commonly found in shops or warehouses.

These areas can contain materials that may pose some degree of risk, such as flammable liquids or items that could lead to slips, trips, and falls, but they do not typically involve the heightened risks associated with hazardous materials or specialized operations. This classification indicates that while there are hazards present, they are generally manageable and do not require the rigorous safety measures needed for areas deemed hazardous or high-risk.

In contrast, hazardous areas involve substances that pose significant fire, explosion, or chemical risks, while high-risk areas are designated for environments where there is a substantial chance of serious incidents. Special areas may include those with unique regulatory or safety requirements not found in ordinary environments. Therefore, the term "ordinary hazard area" accurately reflects the nature of shops and storage facilities that encounter common hazards recognized in building maintenance and safety practices.
