The Lockout tagout procedure is the protective standard for dangerous energy control Lockout tagout (29 CFR 1910.147) issued by OSHA in 1989. The standard sets out the general industrial Lockout tagout requirements and requires authorized employees to confirm that isolation and power outages of the machine or equipment have been completed before starting work on the machine or equipment that has been locked or labeled. Studies have shown that the energy control program reduces the casualty rate by 25 to 50 percent. About 10% of all industrial accidents are due to improper control of hazardous energy. According to OSHA data, about 250,000 accidents are involved each year, of which 50,000 result in injuries and more than 100 are fatal.
