Question 1 of 27070

Q

The air cylinder bottles in the survival craft should be refilled with __________.

🔍 Key Concepts

• Type of gas used in breathing air systems for survival craft and SCBA (self-contained breathing apparatus) • Fire and explosion risk when using high concentrations of oxygen in enclosed spaces • Relevant SOLAS/USCG standards for breathing apparatus and air cylinders

💭 Think About

• Which gas (or mixture) is safe to use at high pressure in confined spaces without greatly increasing fire risk? • What is normally inside SCBA or survival craft air cylinders used for breathing – a special gas, or something very similar to what we breathe normally? • Would a pure gas or a specific mixture be more likely used on a ship to simplify refilling and compatibility with standard compressors?

✅ Before You Answer

• Verify which option could greatly increase flammability in the survival craft environment • Consider what gas is commonly used in SCBA cylinders for firefighters and marine use • Check which choices represent normal breathable gas vs. industrial/inert gases
