At around 16:30 LT four crew members were found unconscious inside the ship’s void space no. 3 where the sewage tank is located. Apparently the crew members went inside the void space in order to dismantle and clean the sewage pump suction filter. When the filter cover was dismantled, poisonous toxic gases escaped from the sewage tank line and contaminated the void space causing the death of one crew member by asphyxia and the injury of the other three crew members. The physical and documentary evidence that was gathered during our investigation, lead to the following conclusions. The direct cause of the accident (death) was asphyxia. The contributing causes of the accident were: “Work risk assessment” for entering into enclosed spaces was not performed. The Safety Management System procedures for entering an enclosed space were not followed, nor were any pre-entry form completed and entry permit given. No safety measures were taken before and after the crew entered the void space for work. The void space is suspect of being already contaminated in some degree due to the poor maintenance of the sewage waste discharge pump The following recommendations were made to the Management Company: The Managers to review the casualty within the scope of the SMS and provide a relevant circular to the vessel (4) The Managers should review IMO Resolution A.1050(27) (and SOLAS III, Reg. 19.3.6) and implement to the Company’s SMS the new requirements which entered into force in 01.01.2015. The Managers to arrange for thorough cleaning of the void space floor from any sewage waste contaminants. Managers also to overhaul the sewage discharge pump. The following suggestions were made for consideration by the Department of Merchant Shipping, Cyprus: A permanent mechanical ventilation system to be installed in such enclosed spaces containing sewage tanks or plants. A piping line of permanent backwash with sea water to be installed on sewage filters, which should be used every time before dismantling of the filter cover is to take place. Tank lines to be required to be equipped with a double suction filtering system with isolation valves. The sewage treatment plants to be subjected to annual surveys by the Classification Societies in order to promote better maintenance by the shipowners.
