What is the minimum amount of time to escape after the alarm sounds for a fixed CO2 flooding system?

The minimum amount of time to escape after the alarm sounds for a fixed CO2 flooding system is recognized as 20 seconds. This timeframe is established to ensure personnel have sufficient warning to evacuate the area before the carbon dioxide is released, as CO2 can displace oxygen and create an immediate hazard to life.

The process is critical for safety, as the concentration of CO2 can increase rapidly, leading to a risk of suffocation or incapacitation. By allowing at least 20 seconds for individuals to exit the area, it enhances the likelihood of a safe evacuation. This duration aligns with safety protocols and guidelines established for environments where CO2 flooding systems are in use, ensuring that employees can act decisively in response to the alarm without putting themselves at unnecessary risk.
