Enclosed Space Entry: Why Confined Spaces on Ships Kill and How to Come Out Alive

Hey guys. No jokes today—this is a deadly serious topic. Every year, people die on vessels due to negligence and rushing. We're talking about working in confined spaces: ballast tanks, cofferdams, chain lockers, void spaces, fuel tanks.

Remember this: iron rusts—this process consumes oxygen. Cargo (coal, timber, chemicals) releases colorless, odorless gases. You open a tank hatch, think "I'll just take a quick look," take two breaths—and you're unconscious. Then the domino effect kicks in: your mate jumps to rescue you without gear—and collapses right next to you. That's how entire watch teams die.

Hard rule: no entry without a properly completed Enclosed Space Entry Permit, signed by the Master. The tank must be ventilated. Gas readings are strict: 20.9% oxygen, 0% flammable gases (LEL), no toxic gases (H2S, CO). There MUST be a person standing at the hatch on a safety harness with a radio and a first aid kit. If they're pushing you into a tank without readings—push back, citing safety regulations. You only get one life.

Has anyone had real incidents or tough training drills on this subject?
