🔍 Key Concepts

• Confined space hazards in boiler drums and tanks • What happens to oxygen levels in a closed steel space over a long, dry layup period • Difference between industrial gas hazards versus sewage/organic decomposition gases

💭 Think About

• Ask yourself: In a clean, dry boiler that has just been opened, what process inside the metal enclosure could change the air composition over time? • Which of the listed gases is most logically produced by steel surfaces and internal corrosion in a closed space, without any sewage or organic matter present? • Think about standard confined space entry training: what is the first atmospheric hazard usually checked before anyone goes inside?

✅ Before You Answer

• Verify which answer choice matches a lack or displacement of breathable air, rather than the presence of sewage or rotting material. • Confirm that a dry-laid-up boiler normally contains no organic waste, so some options are unlikely in that space. • Remember that the main life-support concern in drums and tanks is usually breathable oxygen level before checking for other specific toxic gases.
