Types of fire extinguishers used
Fire events is a common thing nowadays, and as a result, you will come across various types of fire extinguishers used to control. These are explained as follows:
Water extinguishers
Water extinguishers are the best option for class A fires such as paper and wood and not for the case of class B (burning liquids), C (electrical fires), and D (reactive metal fires) type of fires. Here, the fires are likely to spread or make the hazard greater. There is also the water mist extinguishers which give a good alternative for class A and C. Water extinguishers offer a useful role when it comes to pool chemicals. However, you should keep them away from electrical equipment and hazards.
Dry chemical extinguishers
This types of extinguishers work best for either class BC or class ABC. Also, they give the best alternative to the most popular fore situations. The advantage of this type of fire extinguishers is that they feature a blanket leave of non-flammable part on the extinguished material which is essential in reducing the chances of re-ignition. There are two types of these fire extinguishers you’re likely to come across. They include; type ABC and type BC. Type ABC consists of ammonium phosphate as type BC consist of either potassium bicarbonate or sodium bicarbonate.
Carbon dioxide extinguishers
Carbon dioxide extinguishers are the best option for both class B and class C fires. For the class A case, they do not over the needed role since the material ignites in most cases. The unique thing with this extinguishers is that they never leave behind any harmful residue as for the example of dry chemical extinguishers. As a result, carbon dioxide is considered the best choice for an electrical fire that engages a computer or any other delicate equipment.
Metal extinguishers
These are the best for class D fires. They make the whole process of fire protection possible by smothering the fire. The most obvious extinguishing agent used is sodium chloride which matches well with any flammable metal. Under this, category, you will find extinguishing units like graphite based powders, sodium chloride, sodium bicarbonate based agent, and powdered copper metal.
Halotron I extinguishers
As for the case of carbon dioxide, this type of extinguishers never leaves a residue after discharge. Another unique factor with them is that Halotron I causes minimal damages to the ozone layer of the earth as opposed to Halotron 1211. Mostly, you will find this agent discharging as a liquid, and it always features high visibility during the process. No effects of static shock or thermal shock are experienced during its use. Also, no residue is left behind, and it’s non-conducting.
