What is the first step to operate the H2O fire extinguisher?

Explanation:
For an H2O extinguisher, the first step is to puncture the pre-charged cartridge by turning the handle fully clockwise. This type of extinguisher stores water behind a sealed cartridge; turning the handle ruptures that cartridge and opens the valve so water can be released when you squeeze the lever. Without puncturing, pressing the lever won’t discharge anything. Once punctured, you discharge by squeezing the lever, aim at the base of the fire, keep the extinguisher upright (not more than about 45 degrees), and sweep from side to side to blanket the base of the flames.
