The reputation and consistency of the Underwriters Laboratory (UL) mark give manufacturers confidence that their fire extinguishers, parts, and agents adhere to the highest standards of performance and safety throughout the globe. Based on their demonstrated effectiveness in putting out particular types of fires, UL Listed extinguishers can be sold anywhere.
It is generally accepted that the UL Mark on a fire extinguisher and fire extinguisher agents and components denote that they adhere to the standards for performance and safety.
The UL classification can be found on the fire extinguisher label as well. UL checks all extinguishers for efficiency and safety. Using these numerical ratings, you may compare the relative fire extinguishing efficacy of various fire extinguishers. In other words, the figures indicate how small the amount of fire the extinguisher can put out.
Class A and B: C ratings make up the UL ranking. The number from 1-40 is next to the word A. It's the extinguisher's water equivalent, where one is equal to 1¼ liters. For instance, the fire extinguisher has the same efficacy as 5 liters of water if its rating is 4A.
The square feet the extinguisher can put out are indicated by the numbers before B and C. For instance, a fire larger than 20 square feet can be put out with a 20:BC fire extinguisher. The letter C denotes that you can use the extinguisher on electrically energized machinery.
Underwriters Laboratories is a nonprofit company that prioritizes public safety and uses the initials UL. When certain requirements are met, UL conducts product testing to assess performance values and safety risks on a huge range of products and offers third-party certification.
Once a product has the UL listing, it must have gone through testing to make sure it complies with the UL's requirements, which are founded on globally accepted safety procedures.
According to ANSI/UL 771: Fire Testing and Rating of Fire Extinguishers, fire extinguisher capacity is evaluated. Numbers define the ratings before the class (Class of fire) letter. Fire extinguishers are labeled with the classes of fire (Class A, B, C, D, or K) that they are effective against and their relative effectiveness or ability to put out fires. Class A and Class B: C ratings are two typical divisions of the UL rating. For instance, if the label of an extinguisher reads 6A:30B: C, it gives the following information:
A = Class A fire, and the quantity of chemicals or extinguisher agent is equivalent to 1.25 gallons of water in the extinguisher. The amount of equivalents is 6, before the letter A for class fire. Therefore, the 6A's water quenching capacity is 7.5 gallons (6 x 1.25 = 7.5).
B = is the area the fire extinguisher can put out or encompass square feet. The number of equivalents is indicated by 30 before the letters B and C. A 30B can therefore put out a Class B fire that is 30 square feet in size.
C = denotes a non-conductive substance that can also be used to put out a Class C fire.
Fires classified as Class C, D, or K do not have a numerical rating. The fire extinguishing agent for Class C fires should be non-conductive and based on the Class A or B component. Class C fires are either Class A or B fires involving energized electrical equipment. An extinguisher with a 4A: K rating would have 5 gallons of agent inside that was authorized for use on a Class K fire.
These extinguishers are constructed from materials of the finest caliber, including anodized aluminum valves with stainless steel handles, unique nozzles, steel cylinders with skirts, etc.
The extinguishers have been proven to withstand extreme weather conditions and are corrosion-resistant, making them adaptable enough to be used anywhere globally.
There are three different capacities of Kanex UL listed fire extinguishers: 2.5 lbs, 10 lbs, and 20 lbs. They are perfect for dealing with most fire risks usually present in commercial, industrial, and domestic uses, including fires involving burning solid materials, gasoline, oils, gas, and electrical equipment.
Understanding the meaning of the letters and figures on an extinguisher can save a life. But users can only go so far with this information. Extinguishers should be matched to a structure's risks according to important laws that direct building owners and others.
