Introduction

There is a high chance of your encountering an out-of-control fire at

least once in your life, so knowing how to use a fire extinguisher is an

important skill to be able to resort to and knowing about fire control method

and fire protection method. Most of fire extinguishers operate by excluding

oxygen from the site of combustion.

Fire Safety

There are three (3) elements which can produce fire :

1. Fuel – Any combustible materials – solids, liquids, gases

2. Heat – The energy necessary to increase the temperature of

fuel to where sufficient vapours are given off for ignition to

occurs.

Oxygen – The fire only need 16% of oxygen to occur.

Tips For Fire Safety

1. Install Smoke Detectors

- smoke detectors can alert you to a fire in your home in time for you

to escape.

- install detectors on every level of your home.

- Test detectors every month and replace batteries once a year, or

whenever a detector "chirps" to signal low battery power.

2. Plan Your Escape From Fire

- sit down with your family and agree on an escape plan.

- decide on a meeting place outside where everyone will meet after

they escape.

- have your entire household practice your escape plan at least

twice a year.

3. Cook Carefully

- never leave cooking unattended.

- keep cooking areas clear of combustibles materials.

- wear clothes with short or tight-fitting sleeves when you cook.

4. Use Electricity Safely

- if an electric appliance smokes or has an unusual smell, unplug it

immediately.

- replace any electrical cord that is cracked.

- do not overload extension cords or run them under rugs.

5. Crawl Low Under Smoke

- during a fire, smoke and poisonous gases rise with the heat.

- the air is cleaner near the floor.

- if you must escape through smoke, crawl on your hands and

knees to the nearest exit.

- keep your head 12 to 24 inches (30 to 60 cm) above the floor.

Objective

i. Knowing how to use a fire extinguisher.

ii. Knowing about fire control method.

iii. Knowing about fire protection method.

iv. Apply all the method in life for safety.

Demonstrate the proper and safety methods of deploying portable fire

equipment.

Demonstrate to include extinguishers/ hose reels, particularly on the

different classes of real fires.

Fire extinguisher

Classes of fire

Class A

This is suitable for cloth, wood, rubber, paper, various plastics, and regular

combustible fires. It is usually filled with 2 1/2 gallons (9.46 litres) of

pressurized water.

Class B

This is suitable for grease, gasoline or an oil-based fire is usually filled with

a dry chemical. Extinguishers smaller than 6lbs (2.72kg) are not

recommended.

Class C

This is suitable for electrical fires caused by appliances, tools, and other

plugged in gear. It can contain either halon or CO2. Halon 1211 and 1301

is very expensive and depletes the ozone layer, but it is being replaced by

non-depleting agents such as FM200. Note that halon is now illegal in

numerous jurisdictions.

Class D

This is used for water-reactive metals such as burning magnesium and will

be located in factories using such metals. It comes in the form of a powder

that must cover the material to extinguish it.

Class K

This contains a special purpose wet chemical agent for use in kitchen fires

and deep fryers to stop fires started by vegetable oils, animal fats, or other

fats started in cooking appliances.

How to use a fire extinguisher?

Pull the safety pin from the handle. The pin is located at the top of the fire

extinguisher. Once removed, it releases the locking mechanism, allowing

you to discharge the extinguisher.

Aim the extinguisher nozzle or hose at the base of the fire. As explained,

this removes the source or fuel of the fire. Keep yourself low.

Squeeze the handle or lever slowly to discharge the agent. Letting go of

the handle will stop the discharge, so keep it held down.

Sweep side to side approximately 6in or 15cm over the fire until

expended. The sweeping motion helps to extinguish the fire. Stand several

feet or meters back from the fire: fire extinguishers are manufactured for

use from a distance.

Hose reel

How to use a hose reels?

Connect the hose to the outside wall faucet by threading the brass

hose nozzle counter-clockwise on the faucet. Turn on the water by

twisting the faucet knob counter-clockwise.

Open the cover on the hose reel by lifting straight up to pull out the

end of the fire hose.

Peel the hose from the reel as far as necessary to reach the desired

length for spraying the hose.

Turn the crank handle on the side of the hose reel counter-clockwise

to retrieve the hose and coil it back on the spool inside the reel when

finished watering the fire.

Shut off the water to the hose by turning the faucet knob clockwise

Conclusion

By knowing about fire control method and fire protection method, we can

improve our knowledge about fire safety. There is a high chance of we

encountering an out-of-control fire at least once in our life. All of this

method we can apply if fire happen and we can save our self and others

too.
