Lifejacket Rearm Kits - Question

Hi Guys

Looking for some advice on rearming kits for my lifejackets.

Just ordered a couple of UML rearming kits from a proper online chandler to replace my out of date units. Problem is, they have just arrived and despite the “replace by” date on the auto release cap saying 2015, the cylinder is dated 2004. That’s only 2 years after my old 2002 dated cylinders that came with caps showing a 2005 repl date.

Surely that can’t be right?

I assume you mean 2014 not 2004. That's entirely possible as the cylinders would have originally come from a different supplier to the arming bit. You would think they would try and match them up but seems not. I guess you could either return them and ask for new ones or just buy a couple of new cylinders when the time comes. Now you raise the point, when I used to work for a major supplier of all this sort of stuff, we never used to check the dates to match them up.

No, the cylinders are definitely dated 2004, which I assume is manufacturing date not expiry date? (based on the fact my originals were dated 2002 with 2005 caps)

That isn't correct really. I have another company Universal Safety, so I know a bit about this. The date on the cylinder is the manufacture date and the date on the UM auto capsule is the expiry date. It is quite common to have a new cylinder that is a year old but not 9 years! The capsules should also have around 3-4 years life. If you want any other advise then please feel fee to call the guys at the office - 02380 987198.
Thanks
James

James, is it the case that the cylinders don't have a shelf life but are judged by physical condition and weight?

If not, what is the policy on replacing/retaining them? I have seven jackets to check soon and a pointer would be appreciated.

As a rule, we change cylinders if they are corroded, under weight or 5 years or older. We have noticed over the years that the older the cylinder despite the weight being correct, sometimes don't inflate the lifejackets as much as they should.

As a rule for leisure certainly, there is no shelf life only the weight to consider.

Make sure there is no corrosion on the thread or heavy corrosion on the bottle - if the cylinder is free from corrosion and has not been fired then there is no need to change it

There is minimum weight on the bottle as long as the bottle weighs more than at least this it is fine - you can use the PO scales they use for letters to double check very so often but I have never heard of one that "leaked"

This document should also help - your local Lifeboat Sea Safety Officer will only be too glad to offer anyone a free LJ check .

BTW Malcolm Houston is the LSSO for Lough Swilly which of course you knew

I've now had a response from the retailer apologising and promising to send me two new kits next week. He admitted that it looks like someone has cobbled together a kit from some separate parts.

It seems that the capsule is more critical in terms of date but 2 years expiry seems short so i've asked for at least 3-4 years, which i think is reasonable since my 2002 jackets originally had a 2005 expiry on the capsules...

I'll expect the new cylinders to be no more than a couple of years old but in line with the advice here it seems on these weight and condition is more relevant than age.

I haven't weighed any of mine but do I assume the 33g is the total weight I should expect (including the weight of the metal cylinder itself? (sorry if that's a stupid question!)

Not a stupid question but indeed a very important question

The 33g relates to the min weight of CO2 gas in the cylinder and is "normally" the weight associated with 150N LJs.

However there will be another "nominal" weight stamped on your cylinder which is the combined weight of the "liquid" gas and the metal cylinder ie I have one here that states the nominal weight as 139.0g.

I hope this is makes sense
