This code covers the requirements for the design, installation, water supply, and periodic maintenance of internal fire hydrants and first-aid hose reels inside buildings to facilitate early-stage fire suppression.
Covers requirements for the design, installation, testing, and maintenance of internal hydrant and hose reel systems in buildings.
Quick Reference Values

Practical Notes
Ensure dedicated firewater static tanks are always kept at full capacity and never integrated with domestic water storage.
Internal hydrants should be prominently located, ideally near staircase landings or exit routes, ensuring they are free from any physical obstruction.
Fire pumps must undergo regular weekly test runs to ensure they actuate automatically on a pressure drop without failure.
