Fire Extinguishers and First Aid Kits

Extinguisher class, agent and size: matching the fire

This area covers fire protection, first aid and protective gear. For fire, the class on the label says what the extinguisher is for: A for ordinary combustibles like wood and paper, B for flammable liquids, C for live electrical equipment, and K for cooking oils. A multipurpose (ABC) dry chemical unit covers A, B and C, while a water extinguisher is for class A only and must never be used on electrical or grease fires. A 5 lb unit is a typical size for a kitchen, garage or vehicle.

First aid kits: sizing by people, refills and specialist kits

First aid kits are sized by the number of people they serve, such as 25 people, and ANSI-labeled kits follow a published list of minimum contents. Pick the size for your headcount and the likely hazards, not only the room. Refill packs restock a kit after use. Specialist items serve narrow jobs: a bloodborne pathogen spill kit is for cleaning up body fluids safely, and a liquid bandage pipette seals small cuts. Check expiry dates on wipes, ointments and sealed items, and replace them when they lapse.

Questions about Fire Extinguishers and First Aid Kits

How often should I check a fire extinguisher?

Look at it monthly: the pressure gauge should sit in the green zone, the pin and seal should be intact and the nozzle clear. Many places also require a periodic professional inspection, so follow local rules. Replace or recharge it after any use, even a short burst.

Which extinguisher is right for a kitchen?

A multipurpose ABC unit suits general household use, while a class K unit is made for cooking oils in commercial kitchens. Never use a water type on cooking oil or electrical equipment. Mount the extinguisher near an exit, not beside the stove.

How many people should my first aid kit cover?

Count the people who normally use the space and add margin for visitors, then pick a kit rated for at least that many. Kits are marked with a people count, such as 25, and larger counts include more of each item. Add personal medication and any items specific to your hazards.
