LNRC Gravel in Valves

Incident Date

1906-12-05

Incident Description

LNRC 1971 - When diving with two sets it is customary to clip the spare second stage strap through the one in use. With open valve mouthpieces this allows grit to enter the spare second stage so that when the diver comes to swap gags grit enters the exhaust valve and may cause a leak.

Lessons Learned

A solution adopted in the 1980s is to fit a fine gauze across the mouthpiece to prevent the ingress of gravel. Ed.
