Incident Description

This incident is based on true experiences onboard a vessel. Unfortunately, accidents similar to the one you are about to see do happen. Make sure to be careful, and always think twice before you start a dangerous procedure. This video will describe an incident when the chief was about to enter an enclosed space. When entering and enclosed space, there is a significant potential danger for people who are about to enter, this is due to the potential of low oxygen levels.

Unfortunately, do injuries and fatalities involving enclosed spaces happen quite frequently and often include serial deaths when the rescuers enter the enclosed space as well. Rescuing a person in need is usually a good thing, but when it comes to enclosed space, you have to resist the impulse of entering and rescue your colleague. In those cases, the right sort of equipment will be crucial for you and your colleagues' survival. Keep in mind that you might risk becoming two who need to be saved, and the rescue effort will be twice as demanding. The statistics are a bit disputed, but approximately 60% of deaths involve rescuers, and around 30% of fatalities occur in spaces that been tested and found to be safe to enter.

But why is it so dangerous with enclosed spaces? The reason is the lack of oxygen. In the air, there is about 21% oxygen, and between 19.5% up to 23.5% is when we have the best conditions for breathing. Between 16% and 19.5%, the body has great problems performing any physical activities, and already at 14% down to 10% the body is unable to breathe. In an oxygen content of 6% or lower, people die. Keep this in mind before entering an enclosed space.
