Which of the following should NOT be used when training under WPS standards?

Training under the Worker Protection Standard (WPS) is designed to ensure that agricultural workers understand how to protect themselves from pesticide exposure and how to use pesticides safely. Utilizing current and effective training materials is essential to achieve these objectives.

The option that states using outdated materials is unsuitable highlights the importance of providing accurate and relevant information during training. Outdated materials may not reflect the latest safety protocols, regulations, or pesticide application methods, which could lead to misunderstandings or unsafe practices by workers. It is crucial that trainees receive information that is up-to-date to protect their health and safety effectively.

In comparison, in-person demonstrations, video-based learning, and hands-on practices with trainers are valid methods under WPS standards. These approaches promote engagement and retention of essential safety information, ensuring that workers can apply what they learn effectively. Therefore, outdated materials undermine the very purpose of the training, making this option the correct answer.
