Enclosed space entry
Recently the Association noted a crew fatality incident caused by entering an enclosed zinc concentrate cargo hold. A chief officer of a bulk carrier was found lying unconscious in the cargo hold after he entered the hold alone without ventilation and tragically lost his life. It was later established that the cause of death was asphyxiation. Measurements performed the day after the accident showed that the level of oxygen in the air at the stairwell was 2.6%.

Lessons learned
Due to the cargo’s nature of oxidation, ventilation and atmosphere tests are vital before entering holds and breathing apparatus is needed. At sea-level, humans require air that contains minimum 19.5% oxygen. Below that an environment will be unsafe for human life.

进入密闭空间的警示

进入密闭空间
最近协会获悉一起因进入锌精矿货舱引起的船员死亡事故。一艘散货船的大副在没有通风的情况下单独进入货舱后，晕倒在货舱中，不幸遇难，后经证实该名大副因窒息而死。事发当天，测量楼梯井区域空气中的含氧量为2.6%。

经验教训
由于货物氧化的特性，因此在进入货舱前，进行通风和空气测试至关重要，且须佩戴呼吸面具。在海上时，空气中含氧量至少达到19.5%才能满足人类的需求，空气环境低于这个值对于人类生命来说是不安全的。
