Lockout tagout programs are workplace safety procedures to protect workers from hazardous energy during maintenance, repair, and servicing of machines and equipment. These energy sources include electrical, mechanical, hydraulic, pneumatic, chemical, and thermal sources. An energy control program dictates specific procedures for hazardous energy lockout tagout.
LOTO is governed by the occupational safety and health administration (OSHA).
LOTO programs aim to ensure that these energy sources are isolated or controlled before any maintenance or servicing activities are undertaken. This is achieved by using locks and tags attached to the energy sources, isolating switches, and other control mechanisms.
A typical LOTO program involves the following steps:
Preparation: Before any maintenance or servicing activity, the authorized employee responsible for the work must identify all the energy sources that need to be controlled or isolated. This includes identifying the type and magnitude of the energy source, its location, and any hazards associated with the work.
Shutdown: The authorized employee must ensure that all the energy during servicing is shut down or isolated according to the established energy control procedures. This may involve turning off switches, closing valves, or disconnecting electrical or mechanical connections.
Lockout/tagout: Once the energy sources are shut down or isolated, the authorized employee must lock and tag them to prevent them from being turned on or re-energized. Each lock and tag must be uniquely identified and attached to the energy source.
Verification: Before any maintenance or servicing activity begins, the authorized employee must verify that all the energy sources have been properly shut down, isolated, and locked out/tagged out. This may involve testing the equipment or using specialized equipment to verify no energy flow.
Release: Once the maintenance or servicing activity is complete, the authorized employee must remove the locks and tags and restore the energy sources to their normal operating condition.
Overall, LOTO programs are critical for ensuring the safety of workers who perform maintenance or servicing activities on machines and equipment. Employers are responsible for developing and implementing LOTO programs and providing adequate training and resources to ensure employees can use the program effectively.

What are the key elements of lockout tagout programs?
The key elements of a lockout tagout (LOTO) program include the following:
Written LOTO procedures: Employers must develop and document procedures for controlling the release of hazardous energy during maintenance, repair, and servicing activities. These procedures must include the specific steps for shutting down, isolating, and locking out or tagging out each energy source. The procedures must also specify the roles and responsibilities of authorized and affected employees and provide training and auditing requirements.
Training and education: Employers must ensure that all authorized, and affected employees are trained and educated on the hazards of energy sources, the purpose and use of the LOTO procedures, and the safe practices for controlling hazardous energy sources. The training should be provided in a language and format that all employees easily understand.
Identifying energy sources: Employers must conduct an energy audit to identify all hazardous energy sources that need to be controlled or isolated during maintenance, repair, or servicing activities. This includes identifying the type and magnitude of the energy source, its location, and any hazards associated with the work.
Lockout and tagout devices: Employers must provide and maintain appropriate lockout and tagout devices, including locks, tags, chains, blocking devices, and other hardware needed to isolate energy sources.
Periodic inspections: Employers must conduct periodic inspections of the LOTO procedures, including the lockout and tagout devices, to ensure they are in good condition and functioning properly.
Review and update: Employers must periodically review and update the LOTO procedures to ensure they remain effective and current with changes in equipment, technology, or work processes.
Overall, the elements are critical for protecting workers from releasing stored energy during servicing or maintaining equipment, repair, and servicing activities. Employers are responsible for implementing and maintaining a LOTO program and providing the necessary resources and training to ensure their employees can use it effectively.
What goes into an effective lockout tagout safety program?
An effective lockout tagout (LOTO) safety program should be comprehensive and designed to ensure the safety of workers during maintenance, repair, and servicing activities. Here are some key components that should be included in an effective LOTO safety program:
Hazard assessment: A hazard assessment should be conducted to identify all the potential sources of hazardous energy and the level of risk associated with each source. This assessment should be conducted regularly and updated to ensure all hazards are identified.
Written procedures: Written procedures that specify the steps for controlling hazardous energy sources during maintenance, repair, and servicing activities should be developed. The procedures should include clear and concise instructions for each energy source and be readily available to employees.
Employee training: All employees who may be exposed to hazardous energy sources should receive training on the LOTO program, including the procedures, device usage, and the importance of the program for their safety. Employees should be trained at least annually and more frequently if necessary.
Equipment and device selection: Employers should select and provide appropriate equipment and devices for LOTO purposes, including locks, tags, blocking devices, and other hardware to isolate energy sources.
Periodic inspections: Regular inspections of the LOTO program, including the devices and procedures, should be conducted to ensure they are effective and functioning properly.
Audits and reviews: Regular audits and reviews of the LOTO program should be conducted to ensure that it remains effective and up-to-date with changes in equipment, technology, or work processes.
Record keeping: Accurate records should be maintained for all LOTO activities, including training, inspections, and audits. These records should be readily available for review by management and regulatory agencies.
Employers can effectively protect their workers from hazardous energy during maintenance, repair, and servicing activities by including these components in a LOTO safety program. However, it is important to note that compliance with LOTO regulations and standards is critical. Employers should seek expert advice to ensure their program is effective and compliant.
