A new regulation aimed at protecting seafarers who need to enter enclosed spaces, by requiring ships to carry portable atmosphere testing equipment on board, entered into force on 1 July 2016.
The new regulation XI-1/7 Atmosphere testing instrument for enclosed spaces in the International Convention for the Safety of Life at Sea (SOLAS), requires ships to carry an appropriate portable atmosphere testing instrument or instruments, capable, as a minimum, of measuring concentrations of oxygen, flammable gases or vapours, hydrogen sulphide and carbon monoxide, prior to entry into enclosed spaces.
Enclosed spaces covered by the regulation include, but are not limited to, cargo spaces, double bottoms, fuel tanks, ballast tanks, cargo pump-rooms, cofferdams, chain lockers, void spaces, duct keels, inter-barrier spaces, boilers, engine crankcases, engine scavenge air receivers, sewage tanks, and adjacent connected spaces. The list is not exhaustive and enclosed spaces should be identified and listed on a ship-by-ship basis.
