Guest Cupar Womble Posted October 28, 2023 Report Share Posted October 28, 2023 Hi there. Looking at extinguishers for home and wondering why P50 water mist extinguishers are not rated for categories B and C fires unlike most other water mist extinguishers. Can anyone advise?

Rahel Lock Posted October 30, 2023 Report Share Posted October 30, 2023 Hi the manufacturer Britannia chose not to test for Class B and C as the rating would be quite low and people who actually have those fire risks would be better off with a different, more capable model like the A-Foam / B-Foam or Powder.

No water mist extinguisher can carry an official Class B rating as they can't meet the minimum performance requirements stated in the manufacturing standard EN3. They aren't unsafe but just poor performing - a 2L can obtain an 8B rating, 6 litre 21B, but the minimum they should achieve is 34B & 114B respectively. Likewise they can't claim official effectiveness against Class C fires as this is reserved for Powder extinguishers. They still represent a very good choice for the home as they cover all the main domestic fire risks - ordinary combustibles, electrical equipment and cooking oils Quote Link to comment Share on other sites More sharing options...
