IS 2546 : 1974Specification for galvanized mild steel fire bucket

IS 2546 is the specification for galvanised mild steel fire bucket — the simple but mandatory fire-fighting equipment specified for many premises (industrial, public, parking, godowns) where portable fire extinguishers may not be the primary first-response tool.

Use IS 2546 fire buckets where: - Fuel storage areas (oil drums, paint stores) - Vehicle parking (garages, transport depots) - Industrial premises with sand-suppressible fire risk (oil spills, light combustibles) - Construction sites (initial fire response) - Schools / colleges (supplementary to fire extinguisher per IS 2190:2010) - Religious places (open lamps, candles) - Statutory requirement under State Fire Service Acts in many premises

Fire bucket complements IS 2190:2010 portable fire extinguishers + IS 884:1985 hose reels in providing first-response fire-fighting capability. Filled with sand or water, fire buckets are simple, cheap, and effective for small Class A (solid) or Class B (small flammable liquid spill) fires.

Construction: - Galvanised mild steel sheet, ~22 SWG (0.7 mm) - Conical or cylindrical shape - Painted RED with white 'FIRE' lettering - Bail handle - Bucket capacity: 9 litres (standard) - Mass empty: ~1 kg; mass with sand: ~12-15 kg

Acceptance: - Galvanising thickness ≥ 70 g/m² (per IS 4759) - Watertight (no leakage) - Robust handle (5 kg load test) - Painted finish: weather-resistant red enamel + white 'FIRE' lettering

Filled with: - Dry sand (preferred for industrial / parking; works on Class A + small Class B) - Water (for Class A only; not for oil / electrical) - Mix of sand + water (rare; specific industrial use)

Placement (per State Fire Rules + project safety plan): - Adjacent to fire risk (fuel storage, parking, hot work area) - Mounted on bucket stand or wall hook (off floor; visible) - Cluster of 3-6 buckets (one bucket of sand insufficient) - Combined with bucket-stand sign 'FIRE BUCKETS — DO NOT REMOVE'

Fire bucket stand: - 3-tier stand for 6 buckets (typical) - Steel construction; painted red - Wall-mounted or floor-standing - IS 2546 specifies stand dimensions

Maintenance: - Monthly visual: bucket present, sand dry, no rust - Quarterly: replace water in water-filled buckets (stagnation) - Annually: replace damaged or rusted buckets - After use: refill immediately

Acceptance limits: - Bucket capacity: 9 ± 0.5 litres - Galvanising: ≥ 70 g/m² zinc coating - Sheet thickness: ≥ 0.7 mm (22 SWG) - Weight (empty): 0.8-1.2 kg - Handle (bail): can support 25 kg - Test: drop bucket from 1 m onto concrete; no permanent deformation

Quantity (per State Fire Service guidelines, typical):

| Premises | Fire bucket count | |---|---| | Petrol pump | 6-12 (per island + storage area) | | Vehicle parking (per 10 vehicles) | 6 buckets in cluster | | Industrial workshop | 6-12 per shop floor | | Construction site (per 1000 m²) | 6 buckets | | Religious place (with open flame) | 6 buckets | | School corridor | 4-6 per floor | | Godown / warehouse | per fire load (consult Fire Service) |

Cost (typical 2026): - Single fire bucket: ₹150-300 - Cluster of 6 with stand: ₹1500-3000 - Sand fill: nominal cost - Compared to portable fire extinguisher (₹1500-3000 each), fire buckets are very cheap

Limitations: - Effective only for very small fires (< 1 m²) - Not for electrical fires (water conductivity) - Not for oil / fuel (water spreads it; sand mostly suffocates) - Not for chemical fires - Single-use (must refill after each deployment) - Heavy when full (12-15 kg); deploying multiple buckets needs 2-3 people

Effectiveness: - IS 2546 fire bucket buys time for evacuation + portable extinguisher response - Not a replacement for IS 2190 portable extinguisher + IS 884 hose reel system

Marking: - 'FIRE' in white on red bucket - IS 2546 reference - Manufacturer + ISI mark - Year of manufacture

Replacement criteria: - Visible rust / corrosion (galvanising failed) - Dent / damage that compromises capacity - Handle broken - Painted lettering faded / unreadable - Routine: every 5-7 years (galvanising eventually fails)

Defence-in-depth fire-safety strategy:

1. Prevention — material selection, no-smoking zones, hot-work permits. 2. Detection — smoke / heat detectors per IS 2189. 3. First-aid response (very small fires): - Portable fire extinguishers (IS 2190:2010) - Fire buckets with sand/water (this code, IS 2546) 4. Active suppression — sprinklers (IS 15105). 5. Manual fire-fighting — internal hydrants + hose reels (IS 3844, IS 884). 6. Egress — fire stairs, exit signs, emergency lighting. 7. External response — fire department arrival, hydrant access.

Fire buckets are a small but practical layer — used for small spills, initial response while extinguisher is fetched, training drills, low-budget premises. Per NBC 2016 + State Fire Service Acts, fire buckets are mandatory in many premises despite the rise of portable extinguishers. Cost-effective + simple to maintain + effective at the right type of fire.
