A continuously discharged portable fire extinguisher can run out of extinguishing agent in:

A continuously discharged portable fire extinguisher can run out of extinguishing agent in seconds because these extinguishers are designed for quick response to small fire incidents. Once the discharge mechanism is activated, the agent is released at a relatively high rate to suppress the flames effectively and quickly. The amount of extinguishing agent contained in a portable fire extinguisher is limited and is generally enough for brief applications, typically ranging from a few seconds to a few minutes of discharge, depending on the type and size of the extinguisher.

It is essential for personnel to understand that portable fire extinguishers are meant for immediate action on small fires and should be supplemented by additional firefighting resources if the fire is beyond the extinguisher's capacity. This understanding helps reinforce the importance of training and preparedness in emergency response scenarios.
