Stocking on mouth piece

Incident Date

1907-02-05

Incident Description

While diving in a very muddy short sump the stocking that I had put on my titon two 2nd stage became clogged in mud so much so that it was impossible to breath though it. The sump was very short and although getting out required reversing up a mud slope there was plenty of time to get out. The stocking was removed and diving continued.

Lessons Learned

A covering to protect the valve had always worked before protecting the valve from bits of grit but in very muddy conditions a fine mesh can get clogged. In a longer sump this could be more of a problem.
