Enclosed space entry

Emergencies and rescue

Seafarers continue to be killed or injured in enclosed spaces. This is often because they either don’t recognise that they are entering an enclosed space, or that they either don’t know the correct entry procedures or that they have become complacent about the need to follow the correct procedures.
