Fire Extinguisher Usage Guide

 


This guide illustrates the types of fire that each kind of fire extinguisher is suitable for. Under the old standard, the whole of the body of the extinguisher was painted the appropriate colour code to indicate its use. The new standard is BS EN3 part 5, and an extinguisher is Signal Red with a band of colour above the instructions to signify the use of the extinguisher. For more information, call our customer support team on 01724 281044 or use our contact form.
