Fireguard is important in any home or workplace. To create an effective plan of salvation, you need to know what type of fire might happen in your scene. Class A fires Burns Gomi, but class B fire burning flammable liquid or gas. Class B fires require a special flammable liquid fire extinguisher and could not burn out in the same way as a class A fire. We’ll learn everything about class B fires and the flammable liquid fire extinguisher to fight them.
What is a class B fire?
Class B fires don’t really differ from other fires in that they have a basic “fire tetrahedron” elements are the same. To have a fire, you need to fuel, oxygen, heat and chemical reactions. The only difference is the fuel.
Fuel for class B is flammable gas or liquid. One of the following possible sources of fuel for class B fires:
Petrol or diesel
These elements typically found in lacquers, solvents, oils, and oil-based paint. The oil also can serve as fuel for the fire class B. If you have these materials in use or in storage, then you must have a flammable liquid fire extinguisher available for fighting class B fires.
Flammable liquid fire extinguisher
If you have a liquid flammable and gas in your building, you have to save it from sources of ignition. You have not to bring an open flame, cigarette lighters, or other sources of ignition to your warehouse area. The best protection keeps the ignition and fuel sources a separate source. In this way, the fire cannot start. However, you have to provide a flammable liquid fire extinguisher in your warehouse area for emergency situation.
In many cases, this fire will burn out if the fuel source deleted. For example, a fire caused by a propane gas may be burned out if gas turned off. Then, it important to have an emergency shut-off in your workplace. So you can eliminate the source of fuel for the fire.
Problems occur when additional dangerous elements introduced. For example, gas leaks can cause flammable gas to build up in the room. Then when the ignition source is creating the necessary heat and chemical reactions, the fire will spread quickly and can be very damaging. The same applies to gasoline spills. That’s why you have to careful that contain fluids and gases causing class B fires.
Which class of fire extinguisher is appropriate for a fire involving a flammable liquid?
When fighting the fire class B, do not use water. In many cases, the water will only spread the fuel around and create more heat.
To put out the fire class B, you have to cut off the oxygen. You can use the carbon dioxide gas to liquefy oxygen available and stop the burning. Smothering the fire with bicarbonate or potassium carbonate will also work.
Of course, having fire extinguishers that equipped to handle a class B fire definitely ideal, especially in a work environment that vulnerable to class B fires.
Flammable liquid fire extinguisher for class B fires
When looking at a fire extinguisher for your workplace, you have to ensure that they assessed for fighting class B fires. The number before the B shows the area that can extinguish include in square feet. For example, the extinguishers rated 20B can cover 20 square feet. Make sure that your flammable liquid fire extinguisher can fairly cover the area in your workplace where class B fire may occur.
You have a number of different options when it comes to class B fire extinguisher:
There are carbon dioxide fire extinguishers containing compressed gas. The gas will dissolve so this fire extinguisher only effective from 3 to 8 feet.
Dry chemical fire extinguishers contain an extinguishing agent and non-flammable compressed gas extinguishing agent to push over a fire.
HALON fire extinguishers have been discontinued due to environmental concerns. They contain material that interferes with the chemical reaction that causes fires. The chemical called FM-200 replaces Halon but many people prefer other options.
Choose the right flammable liquid fire extinguisher
Armed with this information, you can put together an effective plan of salvation for your building if you at risk for class B fires. Make sure you consult with fire safety experts to ensure workplace safety.
