What is the sprinkler coverage for an ordinary hazard classification?

For ordinary hazard classification, the accepted sprinkler coverage is 130 square feet per sprinkler head. This classification applies to areas where there may be moderate fire risks, such as factories or warehouses with some combustible materials. The coverage allows for effective water distribution to control and suppress fires in these environments.

Sprinklers designed for ordinary hazards are calibrated based on the need for a reliable and robust approach to fire suppression, balancing the size of the area they can cover with water flow rates and spray patterns to ensure adequate firefighting capability.

Understanding this standard is vital for fire safety planning and ensures that structures are equipped with sufficient fire protection systems tailored to their specific hazard classifications.
