Which statement is TRUE concerning a fire in a machinery space?

🔍 Key Concepts

• Fixed CO2 fire-extinguishing systems operation and safety precautions • Dangers of re-entering a CO2-flooded space (machinery spaces in particular) • The proper sequence of actions when a machinery space fire is discovered

💭 Think About

• Think about what happens to the oxygen level inside a machinery space after CO2 is released. Is it safe to open the space quickly? • Consider whether CO2 systems are intended as a first response or a last resort. When would you choose to use portable/local systems instead? • Ask yourself what using water (spray, fog, or solid stream) in a machinery space might do to burning fuel or hot machinery surfaces.

✅ Before You Answer

• Verify the required waiting period before opening a machinery space after CO2 discharge in current regulations or company procedures • Check how training materials describe the priority and timing of using a fixed CO2 system in machinery spaces • Confirm whether water fog or spray can ever be appropriate in machinery-space fires involving fuel and machinery, versus a blanket statement that water must never be used

Question 1 of 27070

Which statement is TRUE concerning a fire in a machinery space?

The space should be opened 5 minutes after flooding CO2 to prevent injury to personnel

Water in any form should not be used as it will spread the fire

The fixed carbon dioxide system should be used immediately, as it is the most efficient means of extinguishment

The fixed carbon dioxide system should be used only when all other means of extinguishment have failed
