Fire Extinguisher Placement

An extinguisher helps only if it is the right kind, in the right place, in working condition and in the hands of someone trained. It is not a substitute for getting out and calling 911.

What does an extinguisher do and not do?

A portable extinguisher is meant for a very small fire at the start. It holds a limited amount of agent and works for a short time. Once a fire grows, or if smoke is thick or the exit is not behind you, leaving is the right choice.

Call 911 for any fire. Having an extinguisher does not change that. Official guidance from NFPA and your fire department explains when to fight and when to flee.

Keep the extinguisher in plain sight and never block it with equipment, since a few seconds of searching can be the difference between a small and a large fire.

How do I choose the right type?

Extinguishers are classed by the types of fire they are made to put out, such as ordinary materials, flammable liquids and energized electrical equipment. A shop may have all three. The label and the maker's instructions say what each unit is for, and a fire protection professional can match them to your hazards.

Using the wrong type can make a fire worse, so ask your fire department or a licensed supplier instead of guessing.

Multipurpose units exist, and the label will say what they cover. Do not assume that a unit rated for one class works on all of them.

Where should extinguishers go?

Locate them where people can reach them quickly and on the way out, near exits and near higher-risk work such as welding and grinding, not in the corner where a fire would start. Mount them visibly and mark the location. Keep the area in front clear.

The number, spacing and mounting height depend on local code and the manufacturer's directions. Ask your fire marshal. Do not use a distance or height from memory.

Place them where you can reach them without passing through the fire, and consider whether a person in a loft or on a platform has one within reach.

• Near exits and risk areas.
• Visible, marked and unobstructed.
• Mounted as the maker and code require.
• Also in vehicles and outbuildings, if advised.

How do I keep them ready?

Look at each extinguisher regularly. Check that it is in place, the safety pin and tamper seal are intact, the gauge, if there is one, shows the correct range and there is no visible damage. Maintenance and servicing schedules are set by the manufacturer and by code, so follow them.

Have units serviced by qualified professionals and replace damaged ones. Keep a simple inspection tag or log.

Never use a unit that shows damage, a missing pin or a gauge outside the correct range. Replace it and have the old one handled by a professional.

What training do people need?

A written instruction on the label is not the same as practice. Many fire departments, suppliers and extension programs offer hands-on training with live extinguishers. Take it, and bring family and workers.

Teach everyone the rule: get out first, call 911, and only then consider using an extinguisher on a very small fire with a clear exit behind you.

Practice the sequence your trainer teaches, since in a real fire stress makes people forget steps. Repetition helps.

• Get out first and call 911.
• Learn from a qualified trainer.
• Refresh training regularly.

What about farm vehicles and outbuildings?

Tractors, combines, trucks, barns and hay storage have their own fire risks. Manufacturer manuals and fire officials can say which extinguishers to carry and where to mount them. Do not assume a shop unit will do for every setting.

Heat, dust and vibration are hard on extinguishers, so inspect them more often if conditions are rough.

Hay, grain dust and manure storage have specific hazards. Ask your fire department about fire detection and suppression for those buildings.

What after use?

Even if the fire is out, call 911 and have the fire department check the site, because fires can rekindle. An extinguisher that has been used, even partly, must be serviced or replaced as the maker directs.

Review what happened, and fix the cause.

Keep a record of each unit's service date and check it twice a year, perhaps at daylight saving changes, so the task is easy to remember.
