......Life Jacket service continued.

So what did I do about my lifejacket (LJ) service? I wanted to weigh the CO2 cylinder to check it hadn't leaked any CO2. The unit was stamped 171g - the minimum weight which indicates it is sufficiently full. But where could I weigh it to a sufficient accuracy? I had a contact at a local commercial organisation and asked to use their scales - no problem; the scales indicated 170g! Hhmmm! Later I was visiting Morrison's in Stone and thought to ask the checkout lady to weigh the cylinder for me as a check - 175g! Hhmmm! Which reading to believe?

I checked the condition of the inflating part of the LJ. All looked well. I checked the reflecting tape sections - strangely one seemed a bit degraded, but still OK. One internet entry said to check the condition of the inflating section by inflating it with a pump, not by mouth because air from one's mouth will be damp and will not be good for the LJ; another advice column said that the modern materials from which LJ's and made can easily deal with a bit of damp air used to test a lifejacket. Which advice to believe? Hhhmmmm!

I needed to make a decision, so chose to use the 'old' gas cylinder to inflate the jacket (perhaps it was under weight anyway?), and send off for a replacement cylinder and trigger cartridge; the new cylinder did not cost that much more than the cartridge alone, and after all this is MY life we are talking about! I left the LJ inflated for 12hours to test for leaks then, after installing the new gas cylinder and cartridge, re-packed the LJ.

'What about the light?' I hear you say. You will recall that I couldn't withdraw the battery unit to check it's 'replace by' date. My LJ is only a few years old so the battery should fine since the battery life expectancy is 5 years. I tested the battery by short-circuiting the terminals on the activation lead that would in an emergency be short-circuited by the sea. The light flashed away brightly! Good!

Job's a good 'un!
