Anthony reference your comments on the P50 fire extinguisher, I am not sure where you are getting your information from ?
May I suggest you actually visit Britannia Fire and we can go through the benefits - or quite simply you can continue to comment via hear say.
Please either drop me an email andy.spence@britannia-fire.co.uk or call me on 01508 488416
The information is from your own latest brochure, I quote:
MAINTENANCE INSPECTION
The extinguisher maintenance programme is a simple
two step process which staff members can carry out on a
monthly basis.
-Visually check for damage
-Check the gauges are showing operational
pressure in green segment
"
Yearly inspection by trained personnel or a Britannia
appointed distributor (giving third party qualification).
- Visually check for damage
-Check the gauges are showing operational
pressure using a magnet to zero - on removal the
gauge will show it is operational. If the pressure is in
the red segment refill under the 10 year
maintenance instructions
-Check the base for damage and
check the manufactured indicator is
within the 10 year life span
-Record inspection detail on the back of the
extinguisher (using a permanent marker) and in the
company log book"
Now I thought that the great idea behind the P50 wasn't just the use of a corrosion proof body, but the initial press suggested it was maintenance free and the double gauge was to allow the user to check without the danger from seized needles.
Yet your latest literature implies an annual service inspection is still required and for most customers who won't be training in house staff this will usually entail the cost of a service visit. I have read the linked forum that says the user gets trained and gauge magnets issued on purchase though - if this is the case, then I can see how it is still an attractive option.
But if I read your brochure alone it doesn't make it clear If I bought one I'd be able to do the service.
So it's great for marine use and places with in house trained staff (which should be all?) and 10 years between extended service is a definite cost saver not seen since Nu Swift's factory sealed powders.
I have suggested a few sites where these would be great, I'm not totally anti them, just a little confused (not by hear say but by official literature).
Now if you bring out a CO2 as well you will be on to something (I always thought you couldn't put a gauge on a CO2 but I have seen it done by a reputable and innovative Indian manufacturer).
