Fire Sprinkler Preliminary Sizing
A first look at an automatic sprinkler system before anyone draws it. It answers whether the Fire Code requires one for your building, which standard governs it, and roughly how much water it will need.
- Whether a sprinkler system is required, from the Fire Code triggers for your occupancy.
- The hazard class of the main spaces.
- A preliminary design flow, and the water supply that flow implies over the required duration.
- A minimum estimate of the number of sprinkler heads.
- Follows: RA 9514 (Fire Code of the Philippines), Section 10.2.6.7, when a system is required; NFPA 13, the sprinkler design standard the Fire Code adopts.
- These are planning figures, not an engineered design. The flow a system is built to comes from a hydraulic calculation by a licensed engineer.
