Fire Extinguisher Buying Guide - 10 Important Tips on Choosing the Extinguisher
Fire extinguisher capsules are one of the most widely used firefighting equipment available in public places, office buildings, gas
stations and more than any other fire extinguishing equipment.
But there is a need for a fire extinguisher in any fire place.
The use of fire extinguishers in some places may not be legally binding, but we may need them at any moment. Perhaps we do not
have a fire extinguisher in our car, workplace or life, but anyway, the presence of electrical and electrical equipment, gas supplies
and plumbing, etc. was somehow associated with fire and the possibility of fire in the place Increase.
Even if there is only one need for a fire extinguisher, it's worth it to be home for many years. Another thing is that shutting down the
fire at the start of the day is both easy and less damaging to our facilities and building.
Important parameters for choosing the correct types of extinguishers
If you plan to purchase a fire extinguisher for your home, work or car, the following tips will help you to buy this vital product:
1) Determine the type of extinguishing agent
The first is to determine the type of extinguishing agent for the fire extinguisher. The type of extinguisher should be appropriate to
the classification of the fire.
For example, for Fire Class E, which is related to the fire of electric and electric equipment, it is better to use dry powder extinguishers
or carbon dioxide, because the use of water and foam extinguishers may spark and connect, or Damage to other parts of your electric
vehicle that is susceptible to water. Water-based extinguishers are relatively cheaper but suitable for solid fires such as wooden materials
(fire class A).
For fire caused by flammable liquids such as gasoline, gasoline, ... (fire grade B), it is also better to use floor-based extinguishers.
The bulky floor with the presence of burning liquids actually interrupts the relationship between oxygen molecules and fuel molecules
and extinguishes the fire, more refractory foamers are used in refineries and fuel storage tanks.
2) Capacity of fire extinguisher
After determining the type of extinguisher it is necessary to determine the capacity (weight and number) required for your building.
Parameters such as the area of the building, the type of materials used, the number of electrical equipment and sources used in the site,
and ... are parameters that determine the weight, number and distance of extinguishers. In some places, you can use a 10 kg capsule of
two or more lighter capsules at closer distances, but in some situations, depending on the location and sensitivity of the place, it is necessary
to use a high-capacity capsule. The article "Legal Requirements and Practical Tips on the Use of Fire Extinguishers" explains some standards
in determining the appropriate number of fire extinguisher caps for buildings and vehicles. For other locations, it's best to advise safety experts
and firemen before buying.
3) Appearance and installation location
Fire extinguishers are usually cylindrical in shape, which are tailored to their type and capacity in a ratio of length to different diameters.
Lightweight capsules are usually mounted on the wall, and heavier caps are usually held in the stall, which is available in two wheeled and
non-wheel-mounted models. Dirt-type fire extinguisher caps are easier to move and are suitable for use in hazardous places and places with
fewer people and stairs without corridors.
4) Functional mechanism
Functionally, fire extinguishers are produced in two groups under pressure and balloon. In the upstream type, a smaller auxiliary capsule
is located adjacent to or inside the main reservoir. This small tank (balloon) contains pressurized gas, which is responsible for providing the
exhaust pressure from the main reservoir (the extinguishing powder is located inside the main reservoir). The advantage of balloon capsules
is that if you have additional balloons, you can easily recharge and recycle the original tank with a special powder. But these capsules are not
usually easy to use and are recommended for firefighters and trained people. For general use, pressurized fire extinguisher capsules
(the typical type that is a pressurized tank containing a powdered extinguisher and high pressure gas) is recommended.
5) Landing length and discharge time
The length of the fire extinguisher capsules is usually between 2 and 7 meters, depending on the volume of contents inside the reservoir,
the pressure inside the reservoir and the time of discharging the capsule (the time when the capsule is drained is usually between 8 and 60 seconds).
Of course, it is also necessary to pay attention to the length of the fire hose capsule. For example, a discharge time of 1 to 6 kg is typically
between 8 to 10 seconds and a throw length of between 4 and 6 meters. The length of the throw is actually the distance between the fire extinguisher
and the fire and some kind of a person's safety distance, and there is no need to move forward from the distance to shut off the fire.
6) Working temperature
This parameter also shows the temperature range of the capsule function under different environmental conditions.
Therefore, it is necessary to pay attention to the temperature range where the capsule is used when purchasing.
This temperature range is usually in the range of 20 to 60 degrees Celsius.
7) body shape and body pressure test
Body shape and body pressure test actually show the quality and life span of the tank and is an important parameter.
Fire extinguishers may not be used for many years on walls. But because they are always ready to use and pressurized, they should
have a high lifespan, good build quality and good welding. In addition, it is necessary to pay attention to the warranty period.
8) Pressure gauge or pressure gauge
This section shows in the fire extinguisher the pressure inside the tank (or inside the balloon). This barometer contains a handwheel
and a plate with two green and red dots. The middle green represents the capsule being recharged, the left red color indicating that
the capsule is empty and the red color on the right indicates the excessive filling of the extinguisher.
9) Body color
The body color of the fire extinguisher capsule usually represents the contents of the capsule. For example, bio-vapor capsules are
green, water and gas capsules are blue, powdered capsules and gas are red, and so on. Of course, the standard colors are different
in different countries and not very cited. So it's best to take into account the type of extinguisher inside the capsule, rather than the
body color of the capsule.
10) Body tag description
The information on the body of the capsule will usually include the following: manufacturer name, type of extinguisher, type of fire
(..., A, B), capsule weight, standard mark, charge and expiry date, instructions for using the capsule, etc. . LT is. You can actually
select the right capsule from the information on the label and the items in this article. The sticker instructions will help people use
the fire extinguisher correctly
This article is based on the years of experience and expertise of the energy company in the field of fire safety due to the
importance of recognizing all types of fire extinguishers and the parameters for choosing the right products for this important and
widely used product.
