In a cartridge-operated dry chemical type fire extinguisher, when the CO2 cartridge is activated, the dry chemical is released from the extinguisher _______________.
AI Explanation
The correct answer is A) with the squeeze-grip on/off nozzle at the end of the hose.
In a cartridge-operated dry chemical fire extinguisher, when the CO2 cartridge is activated, it releases the pressurized gas that then forces the dry chemical powder out of the extinguisher through the hose and nozzle. The squeeze-grip on/off nozzle at the end of the hose allows the user to control the discharge of the dry chemical.
The other options are incorrect because: B) the squeeze-grip is on the nozzle, not the top of the container; C) the control valve handle is not used to activate the extinguisher; and D) the activating handle is not located on the bottom of the container in this type of dry chemical extinguisher.
