How does this code classify building fire hazards?

Buildings are classified into Light, Ordinary, and High hazard categories based on the combustible materials and processes present.

Can domestic water storage be combined with fire fighting storage?

Yes, but the extraction point for domestic water must be at a higher level to ensure the minimum required fire fighting reserve is always maintained.

What dictates the number of fire extinguishers required in a building?

Table 1 dictates the scale based on the floor area, hazard classification, and the class of potential fire (A, B, C, or D).

This code provides comprehensive guidelines for the fire safety of buildings, focusing specifically on the classification of fire hazards and the scale, selection, installation, and maintenance of both first-aid fire fighting equipment and fixed installations like hydrants and sprinklers.

Specifies requirements for the selection, installation, testing, and maintenance of various fire fighting equipment in buildings.

Quick Reference Values

mounting height of extinguisherMax 1.5 m from floor level

max travel distance to extinguisher15 m for most hazard classes

minimum residual pressure at highest hydrant3.5 kg/cm²

minimum underground tank capacity light hazard50,000 Litres

Practical Notes

Always classify the building's hazard level (Light, Ordinary, or High) before sizing the underground water tank and pump capacities.

Fire fighting water storage must be independent, though it can be part of a combined tank provided the fire reserve cannot be drawn down by domestic pumps.

First-aid fire fighting equipment (extinguishers) must be placed in highly visible and accessible locations, ensuring the travel distance does not exceed 15m.
