For Ordinary Hazard Group 1 sprinkler heads, what is the typical maximum coverage area allowed?

The typical maximum coverage area allowed for Ordinary Hazard Group 1 sprinkler heads is 130 square feet. This standard is based on the guidelines provided by the National Fire Protection Association (NFPA) in their standards for automatic sprinkler systems. Ordinary Hazard Group 1 includes areas where ordinary combustibles are present, such as offices and storage rooms.

The calculation of coverage area is crucial because it determines how many sprinkler heads are needed for effective fire suppression in a given space. If the coverage area exceeds this limit, additional sprinkler heads may be required to ensure adequate protection against fires. Understanding this standard helps ensure compliance with fire safety regulations and promotes effective risk management in building designs and fire protection systems.
