An explosion occurred at the government dockyard on Stonecutters Island on the morning of March 2. Six men aboard the vessel were injured in the incident. Emergency crews responded to the scene and transported the casualties to hospital for treatment. It was reported that the explosion resulted from battery gas leakage during the vessel's annual inspection.

3月2日上午，香港昂船洲政府船坞发生一起船舶爆炸事故，造成六名海事部门工作人员受伤。事故发生后，伤者已被紧急送往医院救治。据悉，此次爆炸源于船只年度检查过程中的电池气体泄漏。

The Process of Incident

事件回顾：年度检查突发意外

Police received a report at around 10:30 a.m. that an explosion had occurred at the Stonecutters Island government dockyard. At the time of the incident, marine department personnel were conducting an annual routine inspection of one of their vessels. Unfortunately, during the inspection, a gas leak occurred in the ship's battery, which subsequently triggered a small explosion. The explosion injured six employees. Five of them were expected to be discharged later that day, while one was in serious condition.

据警方通报，上午10时30分左右接到报案，称昂船洲政府船坞发生爆炸。事发时，海事部门工作人员正在对一艘所属船只进行年度例行检查。不幸的是，检查过程中，船上的电池发生气体泄漏，随即引发小型爆炸。爆炸导致六名员工受伤，其中五人可能于当天晚些时候出院，另一人情况有待进一步观察。

Relevant authorities have launched a further investigation to determine the specific cause of the battery gas leakage.

目前，相关部门已展开进一步调查，以查明电池气体泄漏的具体原因。

Marine Battery Safety: A Hazard That Cannot Be Ignored

船用电池安全：不容忽视的隐患

While this incident did not result in more severe consequences, it underscores critical safety considerations for vessel maintenance and inspection operations. Marine batteries—particularly lead-acid types—can undergo electrolysis of water in the electrolyte during charging or fault conditions, generating hydrogen and oxygen gases. Hydrogen has a flammability range of approximately 4% to 75% in air. In the event of inadequate ventilation within a battery compartment, accumulated hydrogen may reach explosive concentrations and ignite upon exposure to electrical sparks, switching arcs, or even static discharge.

这起事故虽未造成更严重的后果，但却为船舶维护及检查作业敲响了警钟。船用电池，特别是铅酸电池，在充电或故障情况下，电解液中的水会被电解，产生氢气和氧气。氢气在空气中的爆炸极限仅为4%——75%，一旦电池舱室通风不良，氢气积聚达到爆炸浓度，遇到电火花、开关电弧甚至静电，即可瞬间引爆。

Such accidents are not uncommon in the shipping, submarine, and industrial sectors. From a technical analysis, the incident occurred while staff were conducting annual inspections, making it highly probable that battery maintenance or charging operations were involved. If the ventilation system was not activated or was faulty, a hydrogen gas pocket could have formed silently. Similar cases are not rare in maritime history, but most go unnoticed because they don't lead to severe consequences.

类似事故在船舶、潜艇乃至工业领域并不鲜见。但从技术角度分析，事故发生时，工作人员正在进行年度检查，极有可能涉及电池维护或充电操作。若通风系统未开启或存在故障，氢气球便悄然形成。类似案例在航运史上并不鲜见，只是多数未造成严重后果而被忽视。

Shipowners and crew members must clearly recognize: batteries are not "maintenance-free" components; their potential risks permeate the entire process of charging, usage, and inspection.

船东与船员必须清醒认识到：电池并非"免维护"部件，其潜在风险贯穿充电、使用、检查全过程。

During vessel inspections, the following details warrant particular attention:

在船舶检查过程中，以下几点细节值得特别关注：

Is Ventilation Effective? Are battery compartment ventilation openings blocked? Are fans operating normally? Does the ventilation rate meet the requirement of no less than 6 air changes per hour? As hydrogen is less dense than air, exhaust points should be located at the top of the compartment.

通风是否有效：电池舱室通风口有无堵塞？风机运转正常？通风量是否满足每小时不少于6次换气的要求？氢气密度低，抽风口应设置于舱室顶部。

Is the Charging Process Controlled? Does the charger have overcharge protection? Is someone on duty during charging? Simple charging setups on older vessels require heightened attention.

充电过程是否受控：充电器是否具备过充保护？充电期间是否有人值守？老旧船舶上的简易充电装置更需重点关注。

Are Electrical Devices Explosion-Proof? Do lighting fixtures, switches, and other electrical equipment inside the battery compartment meet explosion-proof requirements? Ordinary electrical devices can become ignition sources.

电气设备是否防爆：电池舱内的照明、开关等电气设备是否符合防爆要求？普通电气设备可能成为点火源。

Is Daily Inspection Thorough? Are terminals loose or corroded? Is the electrolyte level normal? Are there any cracks in the casing? These issues should be addressed in the monthly inspection checklist.

日常巡检是否到位：接线柱有无松动腐蚀？电解液液位是否正常？外壳有无裂纹？这些问题应在每月检查清单中体现。

Safety is No Trifle, Prevention is Key

安全无小事，防范于未然

The Stonecutters Island incident reminds us once again that vessel safety concerns not only navigation but also permeates every detail of daily maintenance. One oversight regarding gas leakage could lead to casualties. Hong Kong's Marine Department stated it would thoroughly investigate the cause and strengthen safety supervision of dockyard operations.

昂船洲事故再次提醒我们，船舶安全不仅关乎航行，更渗透于日常维护的点滴细节。一次气体泄漏的疏忽，就可能导致人员伤亡。香港海事部门表示将彻查原因，并加强船坞作业安全监管。

While the incident did not result in more severe consequences, it serves as a critical reminder to the industry: no aspect of vessel safety is insignificant, and battery safety is a shared responsibility. From investment by shipowners and daily inspections by crew members to corporate training and protocols, every link in the chain must be approached with systematic attention. This incident underscores the need for the industry to integrate battery safety into routine management, rather than treating it as an isolated concern.

事故虽未造成更严重后果，但足以警示行业：船舶安全没有小事，电池安全更不是"别人家的事"。从船东的资金投入，到船员的日常检查，再到公司的制度培训，每一个环节都需严阵以待。

As of now, the injured personnel are in stable condition, and the explosion has not caused significant damage to other facilities at the dockyard. The incident is under further investigation by the relevant authorities, who will review safety protocols to prevent future occurrences.

目前，受伤员工情况稳定，事故未对船坞其他设施造成严重影响。平安归港，靠的是每一次规范的作业，每一处隐患的排除。愿这起事故成为全行业重视电池安全的起点，而非又一次被遗忘的新闻。
