Fire Suppression Procedures – Learn All About Them

Today, fire is much easier to make than it was. Throughout history, humans have spent quite some time grinding stones or wood to produce friction and make fire. Now, with more igniters at hand, it takes a second or two to light your grill during your summer barbeque party or your cozy fireplace during winter.

However, now that it’s easier to start, problems have become more common and it’s much harder to suppress.

Principles of Fire

Fire results from a chemical reaction when three elements are present: Heat, Fuel, and Oxygen. Take one element away, and the fire can be prevented, suppressed, or controlled. For more information about the Principles of Fire, click here.

Classifications of Fire

Different sources produce different fire types of fire, hence requiring different suppression techniques and equipment. Knowing what fire type you are facing is crucial to either successfully suppressing it or making it worse.

The 4 Basics of Fire Extinguishment

1. Removing the Fuel – Starve

This could be achieved in different ways depending on the fuel. It could be turning off engines and pumps, creating firebreaks through a forest, or simply turning off a gas supply.

2. Removing Heat – Cool

Cooling the fire drops the fuel below its ignition temperature. This could be cooling by water or switching off an element (stove/cooker)

3. Removing Oxygen – Smother

Smothering the fire can be achieved by the use of a fire blanket, foam extinguisher, or reducing the oxygen content by using carbon dioxide (CO2 Extinguisher)

4. Interfering with the Chemical Reaction

Interfering with the chemical reaction of combustion can be achieved using extinguishers like dry powder.

Workplace Suppression Techniques Checklist

  1. Never fight a fire alone
  2. Work with a buddy
  3. Always check before you enter an area (feel doors for heat)
  4. Plan your exit route (fire moves very fast)
  5. Always have two exits
  6. Confine the fire where possible (close doors and windows etc)
  7. Stay low to the ground (crawl if needed)
  8. Suppress only small fires
  9. Watch the fire after it is extinguished (it may re-ignite by itself)
  10. Most of all, DON’T PANIC!

Operating instructions for Fire Situations

  2. Run the hose out to the fire
  3. Turn on the nozzle
  4. Attack the fire if it is safe to do so


  1. Pull out the pin
  2. Aim the nozzle at the base of the fire
  3. Squeeze the handle or trigger
  4. Sweep side to side at the base the of fire

NOTE: Most fire extinguishers will only have between and 20 seconds of discharge. Use them wisely and accurately.

Fire is still one of the most common causes of mortality and property loss. Knowing all about the different Fire Suppression Procedures will enable you to know how to prevent fire and respond to fire situations with ease.

But bear in mind, the most important fire suppression technique that you should always remember is to NEVER PANIC. You know what to do, so keep calm, think well, and stay safe.
