Cable lockout devices secure one or more power sources using a single padlock to prevent power from being restored while equipment is serviced. A cable passes through switches or handles and is pulled tight. A padlock is required to keep the device in place and prevent unintended activation. Cable lockouts are often used on gate valves, mechanical and disconnect switches, and electrical panels. These devices are an integral part of a facility lockout/tagout (LOTO) procedure designed to meet the OSHA standard for the Control of Hazardous Energy (Lockout/Tagout).
