Question 825Deck Safety70% to pass
In order to discharge a CO2 portable fire extinguisher, the operator must FIRST _______________.
AI Explanation
The correct answer is A) remove the locking pin.
To discharge a CO2 portable fire extinguisher, the operator must first remove the locking pin. This is a critical safety step that ensures the extinguisher is ready for use. The locking pin prevents the extinguisher from being discharged accidentally. Once the pin is removed, the operator can then squeeze the two trigger handles together to release the CO2 agent and extinguish the fire.
The other answer choices are incorrect because: B) squeezing the trigger handles without first removing the locking pin would not discharge the extinguisher, C) inverting the CO2 extinguisher is not necessary, and D) opening the discharge valve alone would not properly discharge the extinguisher's contents.
