The correct action to take first when using a fire extinguisher is to pull the pin off of the extinguisher. This step is essential as the pin serves as a safety device that prevents accidental discharge of the extinguisher. By pulling the pin, you enable the lever that releases the extinguishing agent, which is necessary to use the extinguisher effectively.

Once the pin is removed, the next steps would involve pointing the nozzle at the base of the fire and then squeezing the lever to spray the extinguisher. This sequence is crucial for proper and safe operation of the extinguisher in emergency situations, ensuring that the flames can be extinguished effectively. Safety protocols encourage ensuring the path to escape is clear before engaging the fire, which is why approaching the fire without first pulling the pin could be dangerous.
