Recurring enclosed space incidents serve as a stark reminder that entry into such spaces without proper training or following procedures can result in seafarers being killed or seriously injured. Far too often, we also see that seafarers who die in enclosed spaces do so in the course of attempting to rescue fellow crew members.

Spotting a pattern
The Republic of the Marshall Island (RMI) continues to publish new Marine Safety Advisories warning that accidents in enclosed spaces remains one of the most common causes of work-related fatalities onboard ships. According to the flag state’s records, six seafarers died in four enclosed space entry incidents onboard RMI-flagged ships during 2018-2019. Both tankers and bulk carriers have experienced such incidents and it is not only the seafarers’ lives that are at stake. In 2020, two seafarers and three shore personnel died in enclosed space entry incidents on RMI-flagged ships. Two incidents involved shore personnel entering cargo holds without a prior permission from the ship’s crew.
Investigations into the circumstances surrounding enclosed space entry incidents have shown that there are some repeating patterns with regard to how these accidents continue to occur in the same way and in the same locations onboard ship. Some of the similarities noted by the RMI are:
As highlighted by the RMI, these incidents serve as a stark reminder that failure to observe and understand simple enclosed space entry procedures can result in seafarers being killed or seriously injured. They are also reminders that a well-intentioned seafarer who enters an enclosed space to assist a fellow crewmember is likely to become a victim requiring assistance, as well as delay a proper rescue operation and increase the potential for additional deaths.
Dangerous enclosed spaces may not be easily identifiable
An enclosed, or confined, space is normally defined as one that:
Any enclosed space deprived of regular and constant ventilation may become a ‘dangerous space’. Such spaces may have atmospheres deficient in oxygen, and/or contain flammable or toxic fumes, gases or vapours, thus presenting a major risk to health or life for anyone entering the enclosed space. However, while cargo tanks, double bottoms, fuel tanks, ballast tanks, cofferdams, void spaces, etc. are the type of spaces that immediately spring to mind when thinking about enclosed spaces onboard ships, it is important to emphasise that not all dangerous enclosed spaces are easily identifiable.
Recommendation No.1: Review existing procedures
The RMI recommends that ship managers review their enclosed space entry procedures and, if necessary, revise them to ensure they comply with the applicable requirements. This includes adequately prohibiting entry into enclosed spaces by shore personnel prior to the necessary precautions being implemented.
Ship managers should ensure that a risk assessment is conducted to identify all enclosed spaces on board the ship and periodically revisit the assessment to ensure its continued validity. Gard also recommends establishing an inventory of all enclosed spaces on board that seafarers may enter and where there is any likelihood that they might become dangerous. The inventory should record the particular characteristics of the space, the likely hazard involved, and the measures taken to prevent entry unless safety procedures are followed. Any difficulties inherent in a rescue from the space should also be considered, and solutions identified, so that in the event of an emergency, the crew is in the best position to respond quickly.
Recommendation No.2: Ensure that procedures are fully understood and followed
The problem with procedures is that good intentions often become paper-pushing exercises. It is therefore important to ensure that those performing tasks involving entry into enclosed spaces understand that the purpose of the procedures is to prevent accidents and not simply to satisfy the regulators or their immediate superiors. Trying to do a job quickly can result in poor decision making. Never rush a task or minimise safety critical steps due to time pressure.
The RMI recommends that ship managers send a letter or bulletin to all ships in their managed fleet addressing:
Recommendation No.3: Provide proper onboard training
It is important that seafarers are given proper onboard training to help them recognise, evaluate and control hazards associated with entry into enclosed spaces. In addition to conducting mandatory enclosed space entry and rescue drills every two months, the RMI recommends that masters hold a special safety meeting with particular emphasis on enforcing the responsibility that all seafarers have to prevent enclosed space entry related incidents and the need for crew members to resist their natural urge to immediately enter an enclosed space in order to assist a fellow crewmember.
Gard regularly publishes Case Studies for safety meetings focusing on the risk assessment process and identification of the chain of errors that led to an incident. One of our Case Studies addresses entry into enclosed spaces and we encourages masters to use this Case Study as part of their training - for comparison, analysis and discussion among officers and crew onboard their ships.
Gard’s safety awareness campaign on enclosed space entry training
The above findings from RMI’s investigations correspond well with Gard’s own experience. Over the years we have handled numerous cases of death and injury resulting from enclosed space entries and in most such cases, a lack of knowledge of the hazards present and/or taking procedural shortcuts seem to be the prevalent causes.
A near fatal accident involving one of Gard’s own surveyors has also served as a real-life reminder to us that any enclosed space is potentially life threatening - and that even trained professionals make mistakes. Our surveyor entered a void space onboard a barge without testing the atmosphere first and collapsed due to the lack of oxygen inside the space. The story of our surveyor has been captured in one of Gard’s Loss Prevention awareness videos. By sharing an experienced surveyor’s near fatal-mistake we aim to warn crews not to become complacent about the risks associated with enclosed space entries and to emphasize the importance of training and following established procedures - even for those that “have done this a thousand times” and are certain that they “know the procedure from A to Z”.
