Choosing the Right Fire Extinguisher
Handheld and cart-mounted fire extinguishers
Fire extinguishers come in many shapes and sizes. Handheld models can be portable and lightweight, while cart-mounted versions can be more powerful and valuable in more extensive facilities. These portable and cart-mounted devices can be used in various types of fires and are great for use on construction sites and vehicles. Hand-held fire extinguishers are usually lighter than cart-mounted units, and their weight ranges from 1.1 to 30.9 pounds. Cart-mounted extinguishers are typically more than 51 lb. Fire extinguishers are rated by size and weight, numbered from 10 to 80. The smaller B-rated units contain less extinguishing agent, while larger ones have more.
A fire extinguisher should be able to fight all class A and B fires and fires involving electrical equipment. The unit should be easy to use and have a dial that's easy to read. It should also have a tamper seal.
Picking a fire extinguisher depends on what types of fires you plan on extinguishing. Class A fires can be extinguished by water; Class Band C fires are extinguished by CO2 (deprivation of oxygen). ABC (Acid, Water, and Carbon dioxide) extinguishers are designed to extinguish class Band C fires. They usually have a label on them that says ABC.
Carbon dioxide fire extinguishers reduce the oxygen concentration in a closed space. Reducing the amount of oxygen surrounding the fire produces an asphyxiating effect. In contrast, dry chemical fire extinguishers use a powdery compound called ammonium phosphate salt as their extinguishing agent. This compound is straightforward to use in an extinguisher and comprises crushed additives and inorganic salts. It is very effective in combating the initial fire.
Halogenated fire extinguishers
Halogenated fire extinguishers are extinguishers that use halogenated agents to put out fires. UL regulates these extinguishers. They must meet specific standards and be subject to annual testing to maintain their status. They must also undergo maintenance procedures that require the removal of halogenated agents. Fire extinguishers are used in a variety of situations. They come in various sizes and are available in different types of chemicals. Some are dry powder extinguishers, while others use a wet chemical agent. Most of these extinguishers are used for Class A, B, and C fires. However, there are a few exceptions. Some are unsuitable near electrical equipment, such as computers, and therefore not recommended for use in these situations.
Halogenated fire extinguishers have a significant environmental impact. They are known to deplete ozone, so their use is discouraged in some areas. Because of halogens' adverse environmental effects, The United Nations passed the Montreal Protocol in 1987, which imposed stricter regulations on halon production.
Environmentally friendly fire extinguishers
Environmentally friendly fire extinguishers do not release any toxic gasses and are safer for use in the home and workplace. They do not require any specialized safety equipment and are easy to apply. These extinguishers carry a green label from the Environmental Protection Agency and are designed to comply with environmental regulations. Green fire extinguishers use environmentally friendly ingredients like potassium salt to fight fires. They do not release harmful gasses or water into the environment and are perfect for offices, public spaces, and sales. They also have a minimal environmental impact and can be recycled and reused.
Environmentally friendly fire extinguishers are made with clean agents that naturally occur in the environment. They do not contribute to ozone depletion or global warming and dissipate rapidly in the environment.
