    Risk assessment is a detailed and careful assessment of potential harmful factors that are contained within the nature of an operation. It is expected to classify the work and identify high, low and tolerable risk elements to personnel within the working environment. It is meant to provide an action plan which would permit ongoing operations to within limits of a tolerable risk. Check lists are employed to assess the Initial Risk and subsequent detailed parameters effecting the overall final assessment, prior to commencement of the work.

    Pump rooms on tankers are protected spaces and covered by a fixed fire extinguishing system, which is operated from outside of the compartment. (Usually a CO2 operation. Note: Pump rooms are treated as enclosed spaces.) After July 2002, under SOLAS II-2 Regulations 4, 5.10.3/4, cargo pump rooms were required to be fitted with gas detection/bilge alarm systems.

    I would check the condition of all the web straps that they are not worn and that they are secure about the body. Inspect the air content gauge and ensure that the bottle is full. When turning on the air valve I would listen for the ‘whistle’ alarm signal. When placing the mask over the face an even tension must be applied to the mask straps in order to create an airtight/smoke seal. This would be subsequently checked by shutting the air valve so that the wearer would experience the mask ‘crushing’ onto the face, so creating a partial vacuum. This denotes that the wearer is not drawing air from around the sealed mask, and is therefore providing an effective smoke seal. I would then open up the valve to allow the wearer to breath on demand. Finally, communication with the wearer and the control position would be checked to ensure a safe entry.

    You should aim the rocket downwind – because the wind acts on the stretched line, not on the small rocket. This causes the line to ‘bow outward’ and allows the rocket to turn in towards the target area.

    The air in the bottle of the TEMSC is to allow the boat to clear the immediate area in a battened down condition so as to be free from toxics or harmful gases. Provided the boat is correctly battened down and sealed the air will last for a period of 10 minutes and will tend to pressurise the inside of the craft. This is expected to provide enough time for the boat to head upwind into a clean atmosphere.

    The function of the Safety Officer is to primarily promote a safety culture aboard the ship. This may be carried out by regular drills and training exercises. Promotion poster displays, holding active safety meetings or making use of the Training (Video) Manual. The Safety Officer would also be a member of the Safety Committee, under the Chairmanship of the Master, and could expect to draw up the agenda for the meeting. He would normally take the minutes of the meeting and give a safety report at this time. Such a report would include details of any investigation undertaken following an accident. Recommendations from accident findings would be a cause for deliberation by the Safety Committee. Accident reports, obtaining witness statements and taking photographs to support any incident, all fall to the duties of the Safety Officer. The position of the Safety Officer is an appointment and he/she cannot resign this position. In the event the Safety Officer observes unsafe activity on the vessel he has the authority to stop this work immediately. Only the Master can order the resumption of said work. His duty is also to maintain a log account and file of all accidents and accident reports.
