Short note: Fire protection in building

Short answer

Fire protection in buildings includes passive measures like fire-resistant materials, fire walls, and escape routes with fire-rated staircases, and active systems like smoke/heat detectors, alarms, portable extinguishers, hydrants, sprinklers, and static water tanks. Fire prevention involves safe wiring, storage, and regular drills.

Write a short note on fire protection (system) in building.

Fire protection in a building means all the measures that prevent fire, limit its spread, protect occupants and extinguish it. It has passive and active parts (NBC 107, Provisional Recommendation on Fire Safety, covers fire safety in Nepal).

Passive protection (built into the structure)

  • Non-combustible, fire-resistant materials and structural members of proper fire rating (concrete cover, steel encasement).
  • Compartmentation by fire walls, fire doors and fire stops.
  • Means of escape: enough exits, fire-resistant protected staircases, exit signs and emergency lights; limits on travel distance.
  • Open spaces around the building and access for fire engines.
  • Smoke ventilation and enclosed shafts.

Active protection

  • Detection and alarm: smoke/heat detectors, call points, alarm panels.
  • Extinguishing: portable extinguishers, hose reels, hydrants, wet/dry risers, automatic sprinklers, static water tank and pumps, CO2 or foam systems.
  • Fire lifts and pressurised stairs in tall buildings.

Fire prevention

Safe electrical wiring, safe storage of flammable materials, no-smoking areas, and regular drills and inspections.
