This code establishes the fire safety requirements for electrical installations in buildings. It provides guidelines for wiring, switchgear, transformers, and emergency lighting to prevent electrical fires and ensure that installations do not facilitate the spread of fire or hinder safe evacuation.
Lays down general requirements for fire safety of buildings, including fire resistance, means of escape, and fire fighting provisions.
Quick Reference Values
fire resistance of transformer room walls4 hours
clearance for outdoor oil filled transformers6 meters (unless fire separating wall is provided)
transformer oil capacity requiring soak pit> 2000 liters
Practical Notes
Ensure all cable penetrations through fire-rated walls and floors are appropriately sealed with fire-retardant materials to maintain compartmentation.
Wiring for emergency lighting and fire alarms must be strictly segregated from normal power wiring to prevent simultaneous failure during a fire.
Oil-filled indoor transformers must be housed in dedicated rooms with 4-hour fire-resistant walls and adequate oil containment measures.
