🔍 Key Concepts

• CO2 systems used for fire extinguishing in machinery spaces and cargo holds • CO2 behavior in enclosed spaces compared to open deck • Effects on the human body when oxygen is displaced

💭 Think About

• Think about what happens to the air you breathe when a large amount of CO2 is released into a small, closed room. • Which of these options would most directly result from not getting enough oxygen? • Which dangers listed would more likely be associated with electricity, cold contact, or sudden loud pressure waves, rather than a gas release?

✅ Before You Answer

• Identify which choice is specifically related to breathing and oxygen supply. • Eliminate the options that are clearly related to temperature (cold), noise/pressure, or electrical current rather than gas concentration. • Remember that CO2 itself is not flammable, but it can displace breathable air in confined spaces.
