Working at Height at Sea: What Fatal Accident Investigations Reveal About Cargo Hold Safety

The Green Future Incident: What Happened and What Was Found

On 20 August 2024, a seafarer died on board the cargo vessel Green Future while the vessel was drifting near Kii Suido, Japan. The crew were cleaning cargo holds when a seafarer fell from the pontoon deck to the bottom of the hold, sustaining fatal injuries.

The Marshall Islands Maritime Administrator published the investigation report into the incident in May 2026. The findings are significant not because the contributing factors are unusual — they are not — but because they are distressingly familiar. The same combination of factors appears in fall-from-height fatality investigations across the global fleet, year after year: inadequate PPE, insufficient temporary safety barriers, and no clear stop-work authority guidance.

This article uses the investigation findings as a framework for practical safety review. If you work in or around cargo holds, these are the conditions under which people die. Understanding them is not a compliance exercise — it is the difference between going home at the end of a contract and not going home at all.

Contributing Factor 1: Lack of PPE and Prescription Glasses

The investigation found that the seafarer was working without appropriate personal protective equipment. Notably, the absence of prescription glasses is cited as a specific contributing factor — indicating the seafarer may have had impaired vision during the task that contributed to a misjudgement of position or distance.

What This Means in Practice

PPE requirements for working in holds are specific: non-slip footwear, hard hat, high-visibility vest as a minimum; a harness and fall arrest system when working at height or near an unprotected edge. The critical failure is not usually a lack of available equipment — it is the culture that allows work to proceed without it, because “it’s only a short job” or “we’ve done this before without it.”

On medical requirements: the ENG1 or equivalent seafarer medical certificate covers vision requirements. But the gap between what the medical exam assesses and what a task actually demands can be significant in low-light, cluttered, or unfamiliar environments. If you have a vision impairment that requires correction, wearing your glasses or contact lenses is not optional — it is part of your fitness for the task.

Contributing Factor 2: Inadequate Temporary Safety Barrier

The investigation found that the temporary safety barrier in place was inadequate for the task and the environment. This is a consistent finding in hold fatality investigations: barriers are erected, but they are not assessed against the actual hazard level, the size of the working party, or the conditions at the time of work.

What a Compliant Temporary Barrier Actually Requires

A temporary safety barrier for work near an unprotected edge at height must:

• Be rated to withstand the impact of a person falling against it — a rope slung between two clips does not meet this standard
• Cover the full extent of the hazardous edge — partial barriers are among the most common non-conformances found during SMS audits
• Be inspected before work begins and re-inspected after any repositioning of equipment or personnel
• Be clearly visible, particularly in the low-light conditions typical inside cargo holds
• Not be removed or bypassed during the work for reasons of convenience

If the barrier in place does not clearly meet these standards, this is a stop-work situation. Raising it is not a challenge to authority — it is exactly what a good safety culture looks like in practice.

Contributing Factor 3: No Clear Stop-Work Authority Guidance

This is the finding that has the broadest implications. The investigation concluded that there was no clear guidance on who had authority to stop the work if unsafe conditions were identified. In practice, this means that even if a crew member recognised the inadequate barrier as a hazard, the cultural and procedural framework did not give them a clear mechanism to act on it.

Stop-Work Authority: What It Is and Why It Matters

Stop-Work Authority (SWA) is a formal policy provision that gives every worker — regardless of rank — the right and the responsibility to stop any operation they believe is unsafe, without fear of disciplinary action for doing so. It is a requirement under good SMS practice and is referenced in both ISM Code implementation guidance and major operator safety management frameworks.

The key word is “clear.” Vague authority does not work. A stop-work policy has to be explicit: any crew member who identifies an unsafe condition is authorised to stop work, raise the concern, and ensure the hazard is addressed before work resumes. That authority must be reinforced by management behaviour — because if the last person who used it got a hostile response from a supervisor, no one will use it again.

What to Do If Your Vessel Lacks Clear Stop-Work Authority

Check your vessel’s SMS documentation. Stop-Work Authority should be explicitly named. If it is not, raise it with your Master or safety officer as a gap. Under the ISM Code, the Master has explicit authority and obligation to stop any operation that poses a danger to the vessel or persons on board — and that authority cascades to crew through a compliant SMS.

If you raise an unsafe condition and are told to proceed anyway — document it. In writing, in the ship’s log if possible. A written record of a safety concern that was overridden is evidence in any subsequent investigation.

Cargo Hold Cleaning: A Higher-Risk Task Than It Appears

Cargo hold cleaning is frequently treated as routine, low-priority maintenance work — assigned to junior crew with limited supervision, often under time pressure between cargo operations. The Green Future incident is part of a pattern that shows this categorisation is wrong.

Hold cleaning involves working at height, often in low light, on deck surfaces that may be contaminated with cargo residue, in an enclosed or semi-enclosed space with limited emergency access. When you combine all of those factors with time pressure, inadequate PPE, and no clear stop-work framework, the risk level is substantially higher than “routine maintenance.”

Before any hold cleaning operation:

• Conduct a documented task risk assessment — not a verbal briefing, a written assessment
• Confirm PPE requirements for the specific task and ensure equipment is available and serviceable
• Inspect all temporary barriers before anyone enters the working area at height
• Establish and brief the stop-work authority explicitly — who can stop, how they communicate it, what happens next
• Ensure the standby provision is in place if the hold qualifies as a confined or semi-confined space

These are not bureaucratic requirements. They are the specific interventions that the Green Future investigation identifies as what was missing when a seafarer died. Applying them consistently is what prevents the next incident.
