CHMAS provides specialist technical services to a couple of companies on a regular basis whether this be in form of routine kit checks or updating their risk assessments & operating procedures. As a result, I spent a day float testing buoyancy aids (BA) to ensure they are safe to use.
The test is quite simple, you attach a prescribed weight to the BA pop it in some water and wait to see what happens. If it stays afloat the then thats good but if it sinks then its the end of the line for the BA and its discarded. I tested over a hundred BA’s and I’m pleased to say apart from wet feet and the weight falling off a few times that they all passed.
