Complete Guide to Fire Extinguisher Types, IS 2190 Placement & Refilling Protocols

1. Understanding Fire Classes (A, B, C, D, K)

Selecting the wrong fire extinguisher can be fatal. Applying water or standard foam on an energized electrical panel causes electrocution, while using water on a flammable solvent spill spreads the burning liquid pool.

2. Extinguisher Types & Operating Mechanisms

BSS Fire supplies genuine ISI/CE certified Kanex fire extinguishers across Jammu & Kashmir:

1. ABC Dry Powder (MAP 90%): Universal multi-purpose extinguisher for factories, schools, and offices.

2. Carbon Dioxide (CO2): High-pressure seamless steel cylinder with non-conductive discharge horn, ideal for electrical MCC rooms and server rooms.

3. Clean Agent (HFC-236fa / FK-5-1-12): Zero-residue waterless gas extinguisher for cleanrooms, laboratories, and server panels.

4. Mechanical Foam (AFFF): Forms an airtight aqueous film over hydrocarbon liquids, smothering vapor emission.

3. IS 2190 Placement & Travel Distance Standards

Under Indian Standard IS 2190 (Code of Practice for Selection, Installation and Maintenance of Portable First-Aid Fire Appliances):

- Extinguishers must be mounted on wall brackets with carrying handles positioned 1.0m to 1.5m above finished floor level.

- Maximum travel distance from any point inside a building to the nearest extinguisher must not exceed 15 meters.

- Clear, high-visibility photoluminescent operating instruction signs must be mounted above every unit.

4. Refilling Standards & Hydrostatic Testing

Refilling must be performed with genuine chemical agents and pressurized with ultra-pure industrial dry nitrogen (moisture content < 0.005%).

Under IS 2190, all portable extinguishers must undergo hydrostatic stretch testing at 30 bar to ensure cylinder shell structural integrity before being re-commissioned.
