How to Look After Your P50 Extinguishers

Once installed and commissioned, no annual visits are required by a 3rd party engineer for ten years. It is your responsibility to complete the simple annual visual inspection. The visual inspection includes making sure the extinguisher is in place, clean, not visibly damaged, gauge needles are both in green area and that the hose is not blocked. Safelincs will provide you and your staff with free training on this inspection process as part of the initial installation.

After 10 years, you can then contact Safelincs to arrange to swap out the extinguishers (for a fee) to factory-refurbish the P50 extinguishers so that they can be used for another ten years. You should also contact Safelincs if an extinguisher has been used, vandalised or the layout or use of the building is changing. Safelincs will replace P50 extinguishers free-of-charge if they have been used on a fire.

The annual visual inspection by the customer is recorded in the dedicated text boxes on the back of the extinguisher. The fire safety log book is also updated to make sure the customer can evidence that they are keeping their extinguishers in good condition and, very importantly, that the extinguishers are where they are supposed to be. Any business with any type of extinguisher, metal or P50, is of course also legally bound to carry out regular visual ‘present and correct’ inspections, where their staff will verify that the extinguisher is in place and the gauge needles are in the green. These walk-by checks are also recorded in the fire safety log book (again this is the same for metal and P50 extinguishers).

Safelincs offers customers free online fire safety log books to aid with the recording of annual visual inspections and additional ‘present and correct’ checks. The log book includes other fire safety equipment such as fire alarms, emergency lights etc. The online log book also automatically sends reminders to customers if required.
