After removing it from the wall bracket, what is the next step to use a fire extinguisher?

When preparing to use a fire extinguisher after removing it from the wall bracket, the first step is to pull out the pin. This pin serves as a safety mechanism that prevents accidental discharge of the extinguisher. By pulling the pin, you unlock the operating lever and make the extinguisher ready for use.

Once the pin is removed, the user can easily squeeze the handle to release the extinguishing agent. This step is crucial because it ensures that the extinguisher is in a position to work effectively during an emergency situation, allowing for a quick response to a fire. The actions that follow, like aiming the nozzle and squeezing the handle, come after pulling the pin, making it an essential step in the process.
