What is the first action to take when lifting an object to the surface with a lift bag?

1. Test the buoyancy of the bag

2. Mark the object

3. Prepare the ascent line

4. Fill the bag with air

The correct answer is: Mark the object

The first action to take when lifting an object to the surface with a lift bag is to mark the object. This is critical for several reasons. Marking the object ensures that it is easily identifiable both for the diver and for any other divers in the water who may be assisting or observing. This identification helps to avoid confusion and potential hazards, especially if multiple divers are in the area. Additionally, marking the object provides a visual reference for tracking its position. This is particularly important when the lift bag is deployed, as the dynamics of lifting can sometimes cause the object to shift or move. Having a clear indicator allows divers to manage the lift more effectively, ensuring that everyone is aware of what is being lifted. While testing the buoyancy of the bag and preparing the ascent line are important steps in the lifting process, they should be performed after marking the object to maintain safety and clarity during the operation. Filling the bag with air can also be crucial, but it only makes sense once the object has been properly marked and secured for lifting.
