Posted By JB We've just discovered a CO2 extinguisher that carries the warning "do not hold the extinguisher body during operation". It is well known that CO2 extinguishers can give you nasty freeze burns if you hold the discharge horn during operation, but has anyone come across similar with the main body? JB

Posted By TBC I haven't seen one with the warning about the body on before, but it does get a bit cold and frosts up.

Posted By Raymond Rapp Likewise, in my experience mostly through fire training, a person is instructed not to hold the nozzle for obvious reasons - but I do not recall the body as well. Ray

Posted By Allen Higginson I know that it has been relayed through through a hospital fire officer that there was an instance of a nurse who discharged a CO2 extinguisher while holding it by the body,with the result that she damaged her hand when she panicked and pulled her hand free.How true this is I don't know but in the large fixed extinguishers that we use (45KG of gas)your gloves stick to the bottom of the cylinder after discharge.

Posted By Robert K Lewis Allen I would have thought these would be trolley mounted at the size stated so why are people putting their hands on the cylinder? The problems with the body really occur if the gas is discharged from full to empty in long release periods, ie about 2 or 3 maximum to empty the charge. Bob

Posted By JB Thanks for the comments so far but it now transpires that there are 2 differing warning notices on similar extinguishers from the same supplier. One says don't hold the horn, the other says nothing about the horn, but warns not to hold the body. I'm now approaching the supplier to clarify the position because this is far from satisfactory. By the way, the extinguishers are from a well known supplier.

Posted By Robert K Lewis I think there are actually only a few manufacturers and everybody puts their on markings on

Posted By Mark Evans Just a quick point. You can get safety discharge horns fitted to your extinguishers, which work by using a gap between the inner horn and outer horn. Which helps if the horn is accidently touched during discharge (although most training makes a point of telling people not to..).

Posted By TBC The other thing you can get from the discharge tube is shock from static discharge. That will shift your hand :-)

Posted By JB We've completed our risk assessment into the use of extinguishers and this has highlighted a further issue with CO2 extinguishers. There are 3 similar CO2 extinguishers but they carry different warnings -1) do not hold the horn, 2) do not hold the body 3) do not hold the horn or the body. This is confusing and could lead to users holding a particular model incorrectly, resulting in freeze burns. In an emergency situation we can not expect users to read the warning to see which version of CO2 extinguisher they are using. Therefore, we have requested the supplier to change them all over to one version. This will enable us to issue clear instructions during our fire training programme. Has anyone else had similar problems?

Posted By TBC I would have been tempted to just put new labels on warning not to touch the horn and body, rather than change the extinguishers, especially if the extinguishers are already paid for. I think it's something to do with my Scots background. Regards
