Frequently Asked Questions

What are the different types of fire extinguishers available in India?

India has six main types of fire extinguishers: ABC Dry Powder (most common, for Class A/B/C fires), CO2 (for electrical and Class B fires), Foam/AFFF (for Class A and B fires), Water/Water Mist (for Class A fires), Wet Chemical (for Class F cooking oil fires), and Clean Agent/Halotron (for sensitive electronics). Each type uses a different suppression mechanism and is suited to specific fire classes.

Which fire extinguisher is best for home use in India?

For home use in India, a 2 kg or 4 kg ABC Dry Powder extinguisher is the most practical choice — it handles ordinary fires (paper, wood), LPG/fuel fires, and electrical fires in a single unit. For kitchens with cooking oil or LPG, consider also keeping a 1 kg CO2 extinguisher near the stove. JSNM Engineers recommends ABC multipurpose extinguishers for Indian households starting at around ₹1,200.

Which fire extinguisher should I use for electrical fires?

For electrical fires (Class C), use a CO2 extinguisher or a clean agent extinguisher — both are non-conductive and leave no residue. Never use water or foam extinguishers on live electrical equipment as they conduct electricity and risk electrocution. ABC Dry Powder can be used on electrical fires but leaves corrosive residue that damages equipment. For server rooms and switch rooms, CO2 or clean agent is the recommended choice.

What does ABC fire extinguisher mean?

ABC refers to the fire classes the extinguisher can combat: Class A (ordinary combustibles — wood, paper, cloth), Class B (flammable liquids — petrol, diesel, paint, solvent), and Class C (flammable gases and electrical equipment). ABC extinguishers contain monoammonium phosphate dry powder that interrupts the chemical chain reaction of fire. They are the most versatile type for general commercial and industrial use in India.

How do I use a fire extinguisher correctly?

Use the PASS method: Pull the safety pin at the top of the extinguisher. Aim the nozzle at the base of the fire, not the flames. Squeeze the handle slowly and evenly. Sweep the nozzle from side to side at the base of the fire until it is out. Stand 2–3 metres from the fire. If the fire does not go out within 10 seconds or starts to spread, evacuate immediately. Never turn your back on a fire.

How often should a fire extinguisher be inspected in India?

As per IS 2190, fire extinguishers require a monthly visual check (pressure gauge, no physical damage, pin intact), a 6-monthly inspection by a certified technician, and an annual full service with refilling if needed. Every 5 years, extinguishers must undergo hydraulic pressure testing. JSNM Engineers' AMC covers all these inspections and provides dated, signed service records for regulatory compliance.

When should a fire extinguisher be replaced rather than recharged?

Replace a fire extinguisher rather than recharge it when: it is more than 10–12 years old, shows physical damage (dented cylinder, corroded body, cracked hose), has been used even partially (discharge resets the pressure and needs refilling), fails the hydraulic pressure test, or is an obsolete model no longer supported by the manufacturer. Cost comparison: refilling a 5 kg ABC extinguisher costs ₹400–₹600, while a new unit costs ₹1,200–₹2,500.

What is the cost of a fire extinguisher in Ahmedabad?

Current prices in Ahmedabad (2026): 1 kg CO2 extinguisher: ₹900–₹1,200; 2 kg ABC dry powder: ₹800–₹1,100; 4 kg ABC dry powder: ₹1,200–₹1,600; 5 kg ABC dry powder: ₹1,400–₹2,000; 9 kg ABC dry powder: ₹2,200–₹3,000; 5 kg CO2 extinguisher: ₹3,500–₹5,000. ISI-marked extinguishers from reputed brands cost 20–30% more than unbranded alternatives. Contact JSNM Engineers for bulk pricing on 10+ units.

How many fire extinguishers do I need for my office?

Per IS 2190, one 5 kg ABC extinguisher covers 200 sq metres of office space. A typical 1,000 sq ft (93 sq m) office needs minimum 1 extinguisher; a 3,000 sq ft office needs 2–3 units. Additional extinguishers are required near high-risk areas: one near the electrical panel, one in the server room (CO2 type), and one in the kitchen or pantry area. Stairwells and lobbies of multi-floor offices need additional coverage.

Where should fire extinguishers be placed in a building?

IS 2190 specifies: extinguishers must be within 23 metres travel distance for Class A risks, 15 metres for Class B risks. Mount on wall brackets at 1–1.5 metres height (to handle, not base). Place near exits and escape routes — not deep inside rooms. Avoid placement near potential fire sources where heat could damage the cylinder. Each extinguisher must be clearly visible with a red location sign above it. Never store behind furniture or in locked rooms.

What is the difference between CO2 and dry powder fire extinguisher?

CO2 extinguishers discharge carbon dioxide gas — they are non-conductive, leave no residue, and are ideal for electronics and enclosed spaces. Dry powder (ABC) extinguishers discharge monoammonium phosphate powder — they work on more fire classes but leave corrosive residue that damages equipment. CO2 is preferred for server rooms, electrical panels, and laboratories. Dry powder is preferred for general factory floors, vehicle bays, and outdoor use.

How do I know if my fire extinguisher is still good?

Check these indicators: pressure gauge needle should be in the green zone (if equipped), pull pin should be intact with tamper seal, cylinder should have no dents, rust, or corrosion, hose should be crack-free, and the last service date tag should be within the past year. For CO2 extinguishers (no pressure gauge), weigh it — if the weight is less than 10% below the marked full weight, it needs refilling. A 5 kg CO2 should weigh approximately 13–15 kg full.

Can I recharge a fire extinguisher myself?

No. Recharging fire extinguishers requires certified technicians, specialised filling equipment, and pressure testing. DIY recharging is dangerous and illegal — a cylinder recharged incorrectly can rupture. IS 2190 requires that recharging be done by licensed service centres using manufacturer-approved agents. All recharging must be documented with a service certificate. Contact JSNM Engineers at +91 94267 68694 for certified recharging in Ahmedabad.

What is the lifespan of a fire extinguisher?

A well-maintained fire extinguisher has a service life of 10–12 years. After this, cylinders must be condemned regardless of apparent condition. At the 5-year mark, the cylinder must pass a hydraulic pressure test (hydrostatic test) to continue in service. The manufacture date is stamped on the cylinder body. Extinguishers that have failed pressure tests, show corrosion, or have been in service for 12+ years should be replaced immediately.

What fire extinguisher is required for kitchen or cooking oil fires?

Kitchen fires involving hot cooking oil (Class F fires) require a Wet Chemical extinguisher — not ABC powder or CO2. Wet chemical forms a soapy foam layer that cools and seals the oil surface, preventing re-ignition. Commercial kitchens in restaurants, hotels, and canteens are required to have a 6-litre wet chemical extinguisher for each cooking station. Home kitchens using deep fryers should also have a small wet chemical unit.

What is an ISI mark on fire extinguishers and why does it matter?

ISI mark on a fire extinguisher means it has been tested and certified by the Bureau of Indian Standards (BIS) against IS 2878 (for CO2) or IS 15683 (for portable extinguishers). ISI-marked extinguishers meet mandated quality, performance, and safety specifications. For Fire NOC compliance in Gujarat, only ISI-marked extinguishers are accepted by fire inspectors. Non-ISI extinguishers may not perform correctly in an emergency and will fail compliance inspections.

How heavy is a standard fire extinguisher and can anyone operate it?

A common 5 kg ABC dry powder extinguisher weighs approximately 8–10 kg total (cylinder + agent). It can be operated by most adults. Larger 9 kg models weigh 14–16 kg and may be heavy for some users — consider using trolley-mounted units for ease. All employees should be trained annually in extinguisher operation so anyone can respond immediately to a small fire. JSNM Engineers provides on-site training as part of AMC packages.
