Lock Out Tag Out (LOTO) is a safety procedure used in various industries to ensure the complete isolation of hazardous energy sources during maintenance, repair, or servicing of machinery and equipment. The primary goal of LOTO is to protect workers from accidental injury or death due to the unexpected release of energy, such as electrical, mechanical, hydraulic, or pneumatic energy, while they are working on machines or equipment. The Lock Out Tag Out procedure involves the use of physical locks and warning tags to prevent the accidental activation of machinery and energy systems.

The Importance of Lock Out Tag Out Accidental injuries caused by the unexpected activation of machines or the release of hazardous energy can result in serious harm, including electrocution, burns, crushing injuries, and even fatalities. According to the Occupational Safety and Health Administration (OSHA), thousands of workplace injuries and deaths occur every year due to improperly controlled hazardous energy sources. Implementing a comprehensive Lock Out Tag Out program significantly reduces the risk of such accidents, ensuring a safer working environment for employees. Furthermore, LOTO is essential for compliance with safety regulations in many industries, particularly in sectors like manufacturing, construction, and energy production. Regulatory bodies such as OSHA in the United States and similar organizations worldwide require that employers establish and enforce lockout/tagout procedures as part of their occupational safety standards.
