Safety Alert – “Norfolk Range” large wheeled dry powder fire extinguishers manufactured before 2009 by UK Fire International Ltd

Health and Safety Executive – Safety Alert
Department Name:	Hazardous Installations Division, CEMHD, unit 1C
Bulletin No:	HID 1-2015
Issue Date:	12 August 2015
Target Audience:	All premises where large dry powder fire extinguishers are likely to be used for example: chemical industry, offshore industry, merchant shipping, nuclear industry, manufacturing, mining, warehousing, engineering, metals and minerals processing and production.
Key Issues:	‘Norfolk Range’ large dry powder fire extinguishers, manufactured before 2009, 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, consult Britannia Fire Ltd. Service engineers should closely examine, and if necessary, remove the elbow to confirm if there is evidence of water ingress to the discharge tube. If there is any doubt about moisture affecting the powder in the discharge tube, consider subjecting the extinguisher to an extended service including full replacement of the dry powder.
