What is the first step in changing a keg?

The first step in changing a keg is to pull the handle outward, then up. This action is crucial because it engages the disconnect mechanism that releases the coupler from the keg. The coupler connects the beer line and gas line to the keg, allowing for dispensing beer and pressurization. By pulling the handle outward and then lifting it, you ensure that the coupler disengages properly, which is essential for safely and effectively swapping out a keg without risking any spillage or loss of carbonation. Proper technique at this stage also helps maintain cleanliness and prevents over-pressurization.

Moving on to the other options, turning the handle clockwise typically wouldn't be the initial action required for keg changes, as it could imply trying to secure the coupler rather than disconnect it. Removing the keg from the fridge before disconnecting the coupler could lead to difficulties and is not an efficient first step. Disconnecting the gas line could follow after the keg has been properly disengaged and is a part of the later steps in the process. Understanding the exact sequence of actions helps in executing keg changes smoothly and safely.
