After what interaction should trainers ensure all materials are accounted for?

It's crucial for trainers to ensure that all materials are accounted for before sessions begin to establish a safe and organized training environment. Proper preparation helps prevent potential accidents or safety violations during the training activities. Ensuring that all necessary equipment and materials are present and in good condition allows for a seamless flow during the session and minimizes distractions or delays that could disrupt learning. This practice also enhances the experience for participants by allowing trainers to focus solely on instruction and safety, ensuring that everyone is equipped with the tools they need right from the start of the training.
