Is there an MSA approved list of manufacturers or is it a case that it is only the AFFF content which is mandatory?
I ask because there is a huge difference in price (under £20.00 delivered for a 1 litre hand-held and CE marked, around £35.00 for a 2 litre to three or four times as much) and I suspect that most are just priced to match the badge! The plumbed in units are far more expensive of course but probably because there is no mass market to keep prices down.
Nobody questions the need or value of a fire extinguisher within easy reach, but if there are no MSA/FIA stickers needed then perhaps this is one item where money can be saved.
Puts on hard hat and awaits storm of criticism about "You can't put a price on safety".
