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

A 15-pound CO2 extinguisher will typically last around 40 seconds when used continuously. This duration is important to consider under the conditions of an emergency where rapid yet effective action is necessary. The CO2 acts by displacing oxygen, thus extinguishing the fire while also preventing re-ignition, and understanding the duration allows the operator to plan their approach effectively.

During its operation, it is crucial to aim at the base of the fire and move in a sweeping motion. The 40-second time frame allows sufficient delivery of the agent to effectively suppress typical small fires before re-application or other measures are necessary. Being aware of this timing ensures that users can manage their approach to firefighting without running out of the agent prematurely. This understanding is vital for effective fire response and damage control in Navy operations.
