The International Association of Oil & Gas producers (OGP) has published the attached safety flash (OGP safety alert number 227), entitled Subsea oxyarc cutting – risk of explosion. The information can also be found at info.ogp.org.uk/safety.
The safety flash recommends that double isolations that perform a complete break in both poles of the circuit should be used between the surface generator and the diver to form a more effective and dependable isolation.
Guidance contained within the diving supervisor’s manual includes that the knife switch should be mounted in such a way that it cannot fall or be knocked into the on position. Ideally it should be a double pole switch enclosed in a protective wood or plastic box with only the handle showing.
Members are also reminded that both IMCA D 003 and IMCA D 022 are currently under review.
IMCA Safety Flashes summarise key safety matters and incidents, allowing lessons to be more easily learnt for the benefit of all.
