The UK Health and Safety Executive (HSE) has published the following alert regarding a fault in older ‘Norfolk Range’ large dry powder fire extinguishers, manufactured in the United Kingdom before 2009. These extinguishers may be affected by moisture ingress at a threaded joint at the base of the unit, rendering the unit inoperable. The problem may not be identified during ‘routine’ service inspections.
Users should identify if their extinguishers are likely to be affected. If yes, and the extinguisher has been left exposed to adverse conditions since its last extended service, the condition of the elbow joint at the base of the unit should be examined by a competent service engineer.
If you are unsure if your extinguishers are affected by this safety alert, you may wish to consult your supplier.
