I have a contract with Crewsaver for work and we discovered that when staff have jackets in the boot of their cars the cylinders, not the firing mechanisms were vibrating loose over time. Consequently when staff were putting them on the cylinders were not firing or dropping onto the floor as they put them on.

Also several people were wearing (Autos) them in vehicles whilst recovering boats which the HSE say is a big big no no for obvious reasons!

For years we have ordered lifejackets with a auto salt crystal heads and a harness and only one has come back to me after being accidentally set off. Thats 200+ lifejackets over 2 years!

I doubt very very much there is any substance into the realiability of the autos vs the manuals. Surely the added minor expense is worth it particularly with the redundancy of being able to over ride the auto side of it.

I took part in a water safety course at Nene Valley Whitewater Centre (Dodgy water keep your gob shut if you fall in!) and was alarmed that most people who fall into the sea die from Secondary Drowning, i.e. the inhalation of tiny amounts of water even if they have a lifejacket. The guys running the course strongly recommended the face shield things if you were any distance away from land. Worth considering if you go on any trips!

Absolutely. They are small and can be tied to the bladder and folded into the jacket sleeve ready for use after it inflates.

I think it depends on what you are doing with them, I take it you are issuing these for use on ship which I would argue is a very different environment to a rib.

If you have one firing mechanism one thing can go wrong, if you have two firing mechanisms two things can go wrong, which makes it less reliable than the first system.
Equally you could argue that it makes it twice as likely to work when operated. I think that like a lot of safety systems you only really want a lifejacket to work once, the time you are drowning and there is nothing else to help you. But a lifejacket spends most of its time waiting for that moment and how well it waits is the critical thing.
If you think of smoke alarms most of the time you are waving a newspaper at them when you’ve burnt the toast or you are pulling out the battery cos it has spent half the night beeping at you because the battery is going flat. Both of these features make the alarm less reliable, in other words you can not rely on it. If smoke alarms only went off when the house was on fire and you were going to die they would be 100% reliable.
