LOTO Training

By R.W. Hurst, Editor

LOTO training is crucial in maintaining workplace safety and ensuring OSHA compliance. Companies can significantly reduce the risk of accidents and injuries by teaching employees how to control hazardous energy, isolate energy sources, and apply lockout devices and tagout procedures. Furthermore, understanding the differences between authorized, affected, and other employees helps create a safe and efficient lockout/tagout process that benefits the entire organization.


Lockout/Tagout (LOTO) training is particularly important for industries where electrical safety is a significant concern. According to the Occupational Safety and Health Administration (OSHA), failure to control hazardous energy accounts for approximately 10% of serious accidents in various industries. By providing adequate LOTO training, companies can reduce the risks associated with uncontrolled energy release and protect their employees.

One of the main objectives of lockout instruction is to help employees understand the procedures for energy isolation. This process involves identifying, securing, and isolating energy sources to prevent equipment from unexpectedly starting up or releasing hazardous energy during maintenance or servicing activities. By learning these procedures, workers can prevent accidents and maintain a safe working environment.

Another essential aspect is teaching employees how to use lockout devices and tagout procedures. Lockout devices are physical mechanisms that prevent equipment from being energized, while tagout procedures involve attaching warning tags to energy isolation devices to indicate that equipment should not be operated. Proper lockout/tagout practices ensure that hazardous energy is effectively controlled, preventing unintended equipment activation and subsequent accidents.

OSHA compliance is a critical reason for implementing lockout tagout safety. For example, OSHA Standard 29 CFR 1910.147, also known as the Control of Hazardous Energy standard, requires employers to establish a comprehensive lockout/tagout program to protect employees from hazardous energy sources. Companies can comply with these regulations and avoid fines and penalties by providing them to employees.

A successful program should cover several key components. These include understanding the various types of hazardous energy, such as electrical, mechanical, hydraulic, pneumatic, and thermal energy; recognizing the potential hazards associated with these energy sources; learning how to identify and isolate energy sources; and understanding how to apply lockout devices and tagout procedures correctly.

The frequency of instruction depends on the organization's and the employee's needs. OSHA requires that training be conducted when employees are hired, when changes in job assignments or procedures occur or when there is reason to believe that an employee's knowledge or understanding of lockout/tagout procedures needs improvement. Regular refresher courses are also recommended to ensure employees remain knowledgeable about LOTO practices.

Employees are typically classified into three categories: authorized, affected, and other employees. Authorized personnel have received specialized training and are responsible for implementing lockout/tagout procedures. Affected employees operate or use equipment being serviced under lockout/tagout but do not perform the lockout/tagout procedures themselves. Finally, other employees include anyone near equipment undergoing lockout/tagout but not directly involved.
