Approximately how long will a 15lb CO2 extinguisher last under continuous operation?

A 15-pound CO2 extinguisher is designed to discharge its contents effectively for a specific duration, allowing the user to control the situation in the event of a fire. In typical usage scenarios, such as against electrical fires or flammable liquids, a 15-pound CO2 extinguisher can be expected to last around 30 to 40 seconds under continuous operation.

A discharge time of 30 to 40 seconds is sufficient for applying the agent directly at the base of a fire, enabling users to extinguish the flames effectively. The answer of 40 seconds aligns with this expectation, as it allows for a comprehensive approach in applying CO2 to ensure the fire is fully suppressed. This duration is also impacted by factors such as the size and intensity of the fire, the technique used while discharging the extinguisher, and environmental conditions.

Understanding the operational time of a CO2 extinguisher is crucial for safety training and effective fire response, enabling individuals to make informed decisions when dealing with fire emergencies.
