OSHA Standard 29 CFR Part 1910.147

OSHA Standard 29 CFR Part 1910.147, commonly referred to as the Control of Hazardous Energy (Lockout Tagout) standard, is a regulation issued by the Occupational Safety and Health Administration (OSHA) in the United States. This standard is aimed at protecting workers from the unexpected release of hazardous energy during the servicing and maintenance of machinery and equipment. The purpose of the Lockout Tagout (LOTO) standard is to prevent the accidental startup or release of stored energy that could cause injury to workers. This standard applies to various industries, including manufacturing, construction, and general industry, where equipment and machinery are used. Key Definitions:

1. Hazardous Energy: Any type of energy source that can cause harm to workers, including electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other energy sources.
2. Lockout: The placement of a lockout device on an energy-isolating device, usually an electrical switch or valve, to prevent the release of hazardous energy. The lockout device physically prevents the machinery or equipment from being energized.
3. Tagout: The use of a warning tag attached to an energy-isolating device to indicate that it must not be operated or energized. A Tagout device is usually a prominent warning tag or sign that provides information about the person who applied it and the reason for its application.
