Using your fire extinguisher

The U.S. Fire Administration has a four-step guide to fire extinguisher use called PASSPASS acronym for fire extinguisher use
Pull the pin. Point the extinguisher away from you and pull the locking pin.
Aim. Point the extinguisher toward the base of the fire.
Squeeze. Squeeze the lever to activate the fire extinguisher.
Sweep. Spray the extinguisher in a side-to-side motion to cover the base of the fire.

Before you pick up a fire extinguisher:

  • Alert other people in your home
  • Call 911
  • Check your escape route
  • Smoke is deadly
  • Never try to put out a large fire
  • When in doubt, get out

Maintaining your fire extinguisher

In addition, fire extinguishers must be maintained annually in accordance with local, state, and national codes and regulations. This is a thorough examination of the fire extinguisher’s mechanical parts, fire extinguishing agent, and the expellent gas. Your fire equipment professional is the ideal person to perform the annual maintenance because they have the appropriate servicing manuals, tools, recharge materials, parts, lubricants, and the necessary training and experience.

Inspect fire extinguishers at least once a month (more often in severe environments). Fire extinguisher maintenance is important for everyone’s safety.

You must ensure that:

  • The extinguisher is not blocked by equipment, coats or other objects that could interfere with access in an emergency.
  • The pressure is at the recommended level. On extinguishers equipped with a gauge (such as that shown on the right), the needle should be in the green zone – not too high and not too low.
  • The nozzle or other parts are not hindered in any way.
  • The pin and tamper seal (if it has one) are intact.
  • There are no dents, leaks, rust, chemical deposits and/or other signs of abuse/wear. Wipe off any corrosive chemicals, oil, gunk etc. that may have deposited on the extinguisher.

Some manufacturers recommend shaking your dry chemical extinguishers once a month to prevent the powder from settling/packing.

Fire extinguishers should be pressure tested (a process called hydrostatic testing) after a number of years to ensure that the cylinder is safe to use. Consult your owner’s manual, extinguisher label or the manufacturer to see when yours may need such testing.

If the extinguisher is damaged or needs recharging, replace it immediately!

IMPORTANT: Recharge all extinguishers immediately after use regardless of how much they were used.

What is the difference between a fire extinguisher inspection and fire extinguisher maintenance?

INSPECTION: An inspection is a “quick check” to give reasonable assurance that a fire extinguisher is available, fully charged and operable. The value of an inspection lies in the frequency, regularity, and thoroughness with which it is conducted. The frequency will vary from hourly to monthly, based on the needs of the situation. Inspections should always be conducted when extinguishers are initially placed in service and thereafter at approximately 30-day intervals.

MAINTENANCE: Fire extinguishers should be maintained at regular intervals (at least once a year), or when specifically indicated by an inspection. Maintenance is a “thorough check” of the extinguisher. It is intended to give maximum assurance that an extinguisher will operate effectively and safely. It includes a thorough examination and any necessary repair, recharging or replacement. It will normally reveal the need for hydrostatic testing of an extinguisher.
