What should trainers do each time before entering the water?

The action of notifying senior management is not the primary responsibility trainers should focus on before entering the water. The correct approach would involve ensuring that all necessary preparations are in place for a safe and effective training session.

Gathering all equipment is crucial, as it ensures that trainers have everything they need to conduct the training safely and effectively. Ensuring that animals are calm is also vital, especially if live animals are involved, as this helps to create a safe environment for both the trainers and the animals. Clarifying signals with each other can prevent miscommunication during the training process, contributing to a smoother experience.

Overall, proper preparation and assessment of both equipment and conditions are essential steps that trainers should take before proceeding.
