What should be the first step when using a fire extinguisher?

The first step when using a fire extinguisher is to pull the pin. This action allows the extinguisher to be activated and is essential for initiating the firefighting process. Pulling the pin releases a locking mechanism, enabling the user to discharge the contents of the extinguisher when the handle is squeezed. It is a critical initial action that prepares the device for use.

Understanding the order of operations is crucial in emergency situations. After pulling the pin, a user will typically aim the extinguisher at the base of the fire for maximum effectiveness. This sequence is vital because the fire needs to be addressed at its source, and the extinguisher must be ready for action before moving on to the subsequent steps.

While considering safety is important, such as ensuring an exit is visible or obtaining help, these actions are secondary to the immediate need to activate the extinguisher. Proper training in using extinguishers emphasizes the pin-pulling step as the necessary first action in responding to a fire situation effectively.
