🔍 Key Concepts

• Enclosed space / confined space entry procedures on ships • Difference between required safety precautions (what must be done) and optional equipment (what might be used in some cases) • Role of an attendant / standby person during tank entry

💭 Think About

• Think about what the standard safe-entry sequence is for a ballast tank that has been sealed: gas test, ventilate, then what personnel arrangements are required outside the space? • Ask yourself which option describes a normal, general requirement for any safe tank entry, and which options describe either special hazards, incorrect hazards, or over‑specific PPE (personal protective equipment). • Consider why having more than one person physically inside the space can increase risk during an emergency rescue.

✅ Before You Answer

• Verify which practice is universally recommended in enclosed‑space entry guidance (e.g., ISGOTT, company SMS) for having someone outside the space. • Check whether chlorine gas is actually the typical gas produced by seawater acting on steel, or if other gases are of greater concern in ballast tanks. • Check if regulations say you must always wear a gas mask, or if the protective equipment depends on the results of gas tests and the specific hazards identified.

Question 1 of 20

Which statement about entry into a water ballast tank that has been sealed for a long time is TRUE?

After ventilation and testing, and the tank is found safe for entry, someone should standby at the tank entrance while you are inside.

Sea water acts on the ship's metal and generates chlorine gas which may accumulate in poisonous quantities.

You should always wear a gas mask.

A "buddy system" should be used where someone enters the tank with you.
