What is the square footage requirement for an ordinary hazard?

An ordinary hazard classification, often used in fire safety, refers to areas where there is a moderate risk of fire due to the presence of combustible materials and processes. The square footage requirement of 130 square feet aligns with the established guidelines for what constitutes an ordinary hazard area. This size is significant because it helps ensure that the fire protection systems, such as sprinklers, are appropriately designed and installed to mitigate the risks associated with fire in environments where moderate hazards are present.

Understanding the square footage requirement is crucial for fire sprinkler fitters, as it informs them about the necessary coverage and design density needed for effective fire suppression in these areas. By recognizing that 130 square feet is the threshold for ordinary hazards, fire sprinkler fitting professionals can better assess the requirements for installing systems that meet safety standards and effectively protect property and occupants.
