What To Do if Asbestos is Found Onboard

There has been an increased focus on the potential existence of asbestos on board new and existing ships. The Dutch Shipping Department of the Human Environment and Transport Inspectorate (ILT/Scheepvaart) will be carrying out on-board checks for asbestos in the 3rd/4th quarter of 2012. Since the 1st of July 2002 the new installation or use of asbestos-containing materials (ACMs) on board sea-going vessels has been prohibited under SOLAS regulations II-1/3-5. From 1 January 2011, new installation of ACMs (Asbestos Containing Materials) is prohibited without exception for all sea-going vessels.
