Final answer:
A fire prevention plan does indeed define the necessary training employees should receive. It includes various emergency preparedness training aspects such as using fire extinguishers, evacuation procedures, and specific roles during an emergency.
Step-by-step explanation:
The statement that a fire prevention plan defines the training required for all employees who have responsibilities in the plan is true. A comprehensive fire prevention plan not only outlines the measures necessary to prevent fires but also details the training that employees must undergo to ensure they are adequately prepared for an emergency. This training typically includes how to use fire extinguishers, understanding the different types of fires and extinguishing methods, evacuation procedures, and the roles and responsibilities of each employee during a fire emergency.
