In Lockout/Tagout (LOTO) procedures, there are three categories of employees: Authorized, Affected, and Other. Authorized employees are trained and permitted to perform LOTO procedures on specific equipment, meaning they can apply and remove locks and tags. Affected employees are those who operate or work near the equipment being serviced under LOTO, but are not authorized to perform LOTO themselves. Other employees are those who work in the area where LOTO is in effect but are not directly involved in the operation or maintenance of the equipment.
