Final answer:
The employer must review the emergency action plan with each employee it covers when the plan is developed or the employee is assigned initially to a job, as well as when the plan is changed or when the employee's responsibilities under the plan change.
Step-by-step explanation:
According to the Occupational Safety and Health Administration (OSHA), the employer must review the emergency action plan with each employee it covers when the plan is developed or the employee is assigned initially to a job, as well as when the plan is changed or when the employee's responsibilities under the plan change. This ensures that employees are aware of the emergency procedures and their roles in case of an emergency.
For example, if a new employee joins the company, they should be provided with information about the emergency action plan and given appropriate training. Similarly, if there are any modifications to the plan or the employee's job responsibilities, the employer should review the plan with the employee to update them on any changes.
Therefore, the correct answer is option d. Both A and B.
