Powder fire extinguishers and use

Powder Fire Extinguisher (Multifunctional)ABC powder extinguishers (also called dry powder extinguishers), are suitable for fighting fires and fire hazards of classes A, B and C. This includes burning solids, liquid fires and gas fires. They have a very wide range of applications and are therefore used in engineering workshops, cars, boats and sometimes in homes. It is important that customers are aware that powder extinguishers are very powerful, but they also have disadvantages. The powder is very powerful and will spread everywhere when the powder extinguisher is activated. For example, furniture in contact with the powder is very difficult to clean and there is a risk of inhalation, especially in small spaces. Powder extinguishers have a very high extinguishing capacity and can be used to extinguish solid, liquid or gas fires (fire classes A, B and C). In addition, they can be used to extinguish live equipment. However, consequential damage from extinguishing powder on electronic and precision mechanical equipment must be taken into account. Contents of powder extinguishers The powder of an ABC fire extinguisher consists of a mixture of ammonium phosphate and ammonium sulphate. When extinguishing with a powder extinguisher, the remaining powder must be removed with an industrial vacuum cleaner and never cleaned with water.

What is the best use of my powder extinguisher? Powder extinguishers can be used on fires involving organic solids, liquids such as fat, grease, oil, paint, petrol, etc., but never on electrical fires, but certainly on gas fires. A powder extinguisher has a high extinguishing capacity, is suitable for many types of fires, is not electrically conductive and is not sensitive to frost. Attention Safe for use on electrical equipment, although it does not easily enter the spaces in equipment, which can cause the fire to recharge. The powder extinguisher ensures that the fire cools down, so care must be taken to ensure that the fire does not flare up again. There is a risk of inhalation if powder extinguishers are used inside buildings. As a result, powder extinguishers are no longer recommended for use in enclosed spaces. A disadvantage of a powder extinguisher is that the ABC powder is very difficult to clean up after using the powder extinguisher. As mentioned, the ABC powder must be removed with an industrial vacuum cleaner after using a powder extinguisher.

How to use powder extinguishersWhen using powder extinguishers indoors, keep in mind that the powder cloud will limit your view and you may not be able to find the exit. If you are using the powder extinguisher outdoors, check the wind direction. Extinguish with the wind so that the powder cloud and the smoke gases from the fire blow away from you.How does a powder extinguisher work?As with almost all extinguishing agents, the powder functions as a thermal ballast, making the flames too cool for the chemical reactions to continue. Some powders also provide a small chemical inhibition, although this effect is relatively weak. These powders thus provide a rapid knockdown of flame fronts, but may not suppress the fire.
