How long will a H2O fire extinguisher typically discharge?

A typical H2O fire extinguisher discharges for about 30 seconds, making it essential for users to be aware of the duration when managing a fire emergency. Knowing that the discharge time is around half a minute gives the operator a crucial time frame to effectively target a fire while also considering the need to ensure personal safety and possibly retreat if the fire cannot be controlled within that period.

This understanding allows for better planning and execution when using the extinguisher, such as selecting the right approach to extinguish the flames and ensuring that there is enough time to evacuate if necessary. The other options suggest shorter or longer discharge times, which would not provide the same level of effectiveness or assurance in an emergency situation.
