At the beginning of a rescue shift, what is the first thing that must be done?

Checking in at the beginning of a rescue shift is vital for accountability and safety. This process ensures that all team members are present, aware of their roles and responsibilities, and briefed on the situation at hand. It strengthens communication and helps to establish a coherent operational structure, which is essential in rescue scenarios where coordination and teamwork are crucial.

When team members check in, they can also share critical updates on equipment and any potential hazards they may face during the shift. This initial step sets the tone for effective collaboration and helps in aligning the team's focus toward the mission objectives.

While size-up is indeed important as it involves assessing the situation and environment, checking in takes precedence as it lays the groundwork for the entire operation. Similarly, coordinating efforts and ensuring that everyone is on the same page will follow after the check-in process has been completed.
