What is the fire tetrahedron?

To understand how to prevent fires, it is important to know how a fire can occur. Four elements must be present at the same time for a fire to take place:

1. Fuel or combustible material - something to burn, such as paper or wood.
2. Heat - to raise the material to its ignition (burning) temperature.
3. Oxygen - to sustain combustion (the fire).
4. Chemical reaction - the process of burning.

If you remove any of these four elements, the fire will not be able to burn.

What should I know about fighting fires?

Never fight a fire if:

• You do not know what material is burning.
• You do not know what type of fire extinguisher to use.
• You do not know how to use the fire extinguisher.
• The fire is spreading beyond the spot where it started.
• Your instincts tell you not to.

If you are not confident about your ability to handle the situation (even if you are trained in fire fighting), or if you do not have the correct type of fire extinguisher, do not fight the fire. Pull the fire alarm, evacuate the area, and then call the fire department.

What are the different classes of fires?

Fires are grouped into classes which depend on the material or substance that is present.

• Class A - Fires involving ordinary combustibles such as paper, wood, cloth, rubber, or plastics.
• Class B - Fires involving flammable liquids, gases, oil, paints, or lacquer.
• Class C - Fires involving energized (live) electrical equipment such as motors, appliances, or power tools.
• Class D - Fires involving combustible metals such as magnesium, titanium, sodium, and potassium.
• Class K - Fires involving combustible cooking oils, or fats in cooking appliances.

What are the different types of portable fire extinguishers?

To fight the different classes of fires, there are different types of fire extinguishers. Each has its own characteristics, capabilities, and limitations.

Three main types of portable fire extinguishers include:

Water extinguishers: Water extinguishers are filled about two-thirds with water and then pressurized with air. When used for Class A fires, these extinguishers remove the heat from the burning materials.

• Do not use water to extinguish an electrical fire. Water is a good conductor and can increase the possibility of electrocution.
• Do not use water to extinguish flammable liquid or cooking oil fires. Water is ineffective as it helps to spread the liquid and the fire.

Carbon Dioxide (CO₂) extinguishers: The extinguishing media is pressurized CO₂. When used for Class B and C fires, the CO₂ covers the fuel by blanketing it, and stops the reaction at the surface by displacing oxygen. Be thorough when using a CO₂ extinguisher. It has a moderate spray range and last only 10 to 30 seconds. A hard horn attached to the end of the spray tube helps to contain and aim the spray at the target area.

• Do not use CO₂ extinguishers in confined spaces as CO₂ can displace the oxygen in the air, making breathing difficult. Only use in a confined space if workers have appropriate respiratory protection.
• Do not use CO₂ extinguishers for Class A fires because the fire may continue to smolder and re-ignite after the CO₂ disperses.

Dry Chemical extinguishers: Dry chemical extinguishers are the most common and available in few types. These extinguishers will be marked for the classes they are designed to extinguish (e.g., ABC type extinguisher will put out Class A, B and C fires). The extinguishers discharge a blanket of fine powder which creates a break between the fuel and the oxygen in the air. The powder also works to break the chemical reaction. Be accurate when using as they have a short to moderate spray range and last only 10 to 25 seconds.

Be cautious of the residue after using dry chemical extinguishers. The residue can damage motors, computers and other electrical equipment.

Below is a summary of these and other common extinguishers.

How will portable fire extinguishers be marked?

Portable fire extinguisher may use the following markings to indicate which class of fire they are designed to fight. These symbols are recommended by the National Fire Protection Association (NFPA) in the USA. The symbols may be shown using colours.

What you should know when using a portable fire extinguisher?

Always:

• Be sure that you are trained to use a fire extinguisher before you try to fight a fire.
• Know what type and class of material is burning.
• Use the correct fire extinguisher type to fight the fire.

Remember, if you feel that you cannot safely extinguish the fire using the portable extinguisher available and if you have not already done so, pull the fire alarm, evacuate the area, and then call the fire department.

When using an extinguisher, use the PASS system - Pull, Aim, Squeeze, Sweep.

1. Pull the pin on the extinguisher.
2. Aim the extinguisher.
3. Squeeze the trigger or top handle.
4. Sweep the fire area with the extinguisher's spray until the fire is completely out.

For floor fires, sweep from the edges in. For wall fires, sweep from the bottom up.

• Never walk away from a fire, even if you think it is out. The residue may reignite.
• Always stand between the escape route and the fire so you can leave safely if the fire grows.
• If the fire grows too large, leave the area. Activate the fire alarm to evacuate the area.

What you should know about selecting, locating, and maintaining portable fire extinguishers?

As an employer/contractor, you must:

• Use the proper size of extinguisher.
• Install extinguishers according to the height requirements stated in your jurisdiction's Fire Code.

• Service portable fire extinguishers at least once a year, or when the monthly inspection indicates servicing is necessary.
• Keep written records showing maintenance items such as serial number and type of extinguishers, location, inspection date, description of tests, date of next inspection, date of annual servicing, comments and inspector's signature.
• Only allow service by trained persons with suitable testing equipment and facilities.

Do portable fire extinguishers require WHMIS labels?

Depending upon what type of extinguisher it is, a fire extinguisher may be classified as a hazardous product under WHMIS 2015. Many extinguishers will meet the compressed gas criteria and will therefore require a WHMIS label. Other extinguishers may also be classified in other WHMIS classes due to the physical or health effects of the extinguishing media.
