ABC Powder Fire Extinguishers

ABC powder fire extinguishers are the most versatile and size for size, the most powerful of fire extinguishers.  And in some countries, the USA in particular, they recommend powder alone. But here in the UK, regulations are slightly different, and powder is not recommended in areas where there are escape routes, because it can create a cloud, thus obscuring the escape route.  

And, powder can cause health problems, where there are persons suffering from asthma and other respiratory problems. 

As well as this, the powder creates a cloud of dust, which is very abrasive.  This can cause problems in machinery and create an awful mess to clear up. Because an extinguisher is much regarded as a first aid fighting device, we would normally recommend that powder is used along with other extinguishers which don’t create such a mess.  

Powder is certainly the best where it comes to vehicles.  And because are the most powerful size for size, they are the best choice for the cabs of vehicles.  

We would always recommend powder in cabinets for protecting the load of the vehicle as well. Powder also has the advantage that it is unaffected by low temperatures, so can be used in areas where it is freezing. 

For certain applications, it is also possible to get wheeled extinguishers of a larger size than the portable ones for specific risks.  But as always in these cases, these cases, you need specific advice for the actual circumstances.  

ABC powder fire extinguishers are versatile extinguishers that can be used on fires involving Class A (ordinary combustibles), Class B (flammable liquids and gases), and Class C (electrical) fires.
