Emergency Ascent

I realize the swivels mentioned in this post are the type that allow movement of the second stage at angles other than in line with the hose. For sure there have been problems with these and in some cases recalls issued. However, it is important to know that ALL second stage hoses have swivels. There is a swivel that allows the regulator to rotate about the axis of the hose. This is accomplished by using a dynamic o-ring inside the hose fitting that mates with the second stage. The reason it is important to know this is because one can be easily fooled into believing everything is normal when in fact the fitting at the second stage (or the first stage) could be deceptively loose. We are all used to seeing our second stages rotate about the hose so we become complacent. ALL hose fittings should be checked to make sure they are AT LEAST hand tight.

Here are a few more checks everyone can do:
