What is the first step in operating the Water Fire Extinguisher?

The correct answer highlights an important initial action when operating a Water Fire Extinguisher. Turning the handle clockwise fully is crucial because it allows the user to activate the extinguisher and release the water. This step is essential for ensuring that the extinguisher is operational and that the water can be dispensed effectively onto the fire.

Before engaging with the fire, activating the extinguisher is necessary to ensure that the equipment is ready for use and can deliver the intended suppressive action. Other steps, such as assessing the size of the fire or checking additional components of the extinguisher, may be important, but without first activating the extinguisher, those assessments would be moot as the device wouldn’t be ready to combat the flames. This underscores the importance of proper operational sequence in emergency response situations.
