Instructions on how to use powder extinguishers for fire fighting

The following content will guide you how to use powder extinguishers for fire fighting for 2 types of extinguishers: portable and trolley type:

1. For portable type

In the event of a fire, carry the extinguisher to the fire site.

Shake the jar 3-4 times to loosen the powder, pull the lead clamp, choose the wind direction to direct the speaker to the source of the fire.

Keep the bottle at a distance of 1.5m depending on the type of bottle, squeeze the valve to let the fire extinguishing powder spray out, when the gas is weak, approach and move the spray speaker back and forth to completely extinguish the fire.

2. For trolley tank

+ Push the car to the place of fire, pull the nozzle to lead the powder, direct the spray nozzle to the source of the fire.

+ Pull the safety pin (lead clamp), pull the main valve on the mouth of the tank perpendicular to the ground.

+ Hold the nozzle tightly, choose the wind direction and pull the trigger, the powder will be sprayed.

3. Attention

Read the instructions, carefully grasp the function of each type of bottle to arrange the bottle accordingly.

When spraying, must stand at the wind direction (external fire); stand near the door (fire inside). When spraying, it must be turned off completely to stop spraying.

When extinguishing liquid fires, it is necessary to spray extinguishing agent to cover the fire surface, avoiding direct spray on the liquid to prevent them from splashing out, causing a bigger fire.

When spraying, depending on each fire and the amount of propellant remaining in the tank, choose the appropriate position and distance to spray.

Used fire extinguishers should be kept separate to avoid confusion.

When spraying, keep the can in an upright position

4. Notes when using and storing fire extinguishers

Put in a place that is easy to see, easy to get, and convenient for fire fighting.

Place in a dry, ventilated place, avoid places with strong sunlight and heat radiation, the highest temperature is 500C. If left outside the house must have a roof.

When moving, need to be gentle. Avoid direct exposure to high temperature, vibration equipment.

The tank must be checked regularly according to the manufacturer’s regulations or at least every 3 months. If the needle is below the red line, the gas must be refilled.

Check the propellant through a manometer or balance and compare it with the original mass. Check the dough mass by weighing comparison.

Regularly check, maintain, and replace if damaged parts of the tank are found: Spray speakers, nozzles, locking valves. Replace leaky cylinders.

How to use a CO2 . gas fire extinguisher

Do you know how to use a CO2 fire extinguisher? The following content will guide you how to use and some notes when using CO2 cylinders for fire fighting:

1. Instructions for safe and effective use of CO2 fire extinguishers

Step 1: When a fire occurs, bring the CO2 tank to approach the fire.

Step 2: One hand holds the spray speaker towards the fire source at least 0.5m, the other hand unlocks the cylinder valve

Step 3: Squeeze (or turn) the valve so that the gas spontaneously sprays out to extinguish the fire.

2. Some notes when using CO2 fire extinguishers

The fire was completely extinguished before it stopped spewing.

Read the instructions carefully, understand the features of each type of extinguisher to put out fires accordingly.

For liquid fires, must be sprayed on the burning surface, avoiding spraying on the liquid.

Depending on each fire, choose the appropriate location and distance to spray.

Note that CO2 cylinders should not be used to extinguish outdoor fires. When using, must choose the wind direction. Never stand against the wind. Only handle the plastic and rubber parts on the nozzle and the sprayer to avoid frostbite.

– If spraying in a closed room, must notify everyone to leave the room, plan an exit after spraying.

Principles of extinguishing fire with a fire extinguisher

• Read the instructions carefully, understand the features and effects of each type of bottle to arrange the bottle accordingly.
• When spraying, must stand at the wind direction (external fire); stand near the door (fire inside).
• When spraying, you have to wait for the fire to go out before you stop spraying.
• When extinguishing liquid fires, it is necessary to spray extinguishing agent to cover the fire surface, avoid spraying directly into the liquid to prevent them from splashing out, causing a bigger fire.
• When spraying, depending on each fire and the amount of propellant remaining in the tank, choose the appropriate position and distance to spray.
• Used fire extinguishers should be kept separate to avoid confusion.
• When spraying, keep the can in an upright position

How to check, store and maintain fire extinguishers

– Put it in a place where it is easy to see, easy to get, and convenient for fire fighting.

– Put in a dry, ventilated place, avoid places with strong sunlight and radiation, the highest temperature is 50 degrees Celsius.

– If left outside the house must have a roof.

– Be gentle when moving. Avoid direct exposure to high temperature, vibration equipment.

– Must regularly check the bottle according to the manufacturer’s regulations or at least every 3 months. If the needle is below the green line, the gas must be refilled.

– After opening the valve, it is necessary to refill the fire extinguisher, before loading and unloading the sealing components, remove and clean the parts that have been contaminated with powder.

– If there is still pressure, before removing the pressure must reduce the pressure by squeezing the valve slowly to let the gas out gradually, the manometer needle indicates the value of O. When opening the “hissing” sound, must immediately stop and check again.

– Before each new gas charge and after 5 years of use, the tank shell must be hydraulically tested, after reaching the required strength, it is allowed to use, at least 30 MPa.

– Check the propellant through a manometer or balance and compare with the original mass.

– Check the powder weight by comparison weighing.

– Check faucet, spray speaker
