1469. If you hear a CO2 activated alarm warning you to evacuate the engine room, how much time do you have to evacuate before the CO2 gas is released into the engine room?

The standard time delay between a CO2 evacuation alarm and system discharge in the engine room is 20 seconds, allowing crew to escape before asphyxiating gas is released; this delay is designed solely for personnel evacuation and is not intended for continued work or firefighting.
