HiLink will explain this as concisely as possible, ensuring the content remains accessible-after all, establishing an effective and comprehensive lockout/tagout procedure involves numerous steps, and even minor oversights can lead to confusion or overwhelm. So, let's get straight to the point.

 

According to the U.S. Occupational Safety and Health Administration (OSHA) guidelines, a lockout/tagout procedure must include the following elements to be considered compliant:

 

1. Formal Written Procedures
2. Energy Control Procedures
3. Identification of Equipment Requiring Lockout/Tagout
4. Inspection of Lockout/Tagout Devices
5. Mandatory Training for All Personnel

 

Formal Written Procedures-Your procedures must include the following:

1.Company Policies
2.Assignment of Responsibilities
3.Lockout/Tagout Procedures
4.Equipment Restoration
5.Collective Lockout/Tagout and Shift Handover
6.Contractors and External Suppliers
7.Training
8.Appendices

 

Energy Control Procedure

This procedure ensures employees are not present in areas where they may be exposed to mechanical start-ups, unexpected energization of equipment, or hazardous energy releases, particularly when locks or tags have been removed. It also ensures proper shutdown, isolation, interlocking, and securing of machinery or equipment to control hazardous energy, and standardizes the procedures for setting up, removing, and transferring lockout/tagout devices.

 

Identify Equipment Requiring Lockout/Tagout

When developing lockout/tagout procedures and energy control protocols, it is essential to identify all machinery requiring lockout/tagout operations during maintenance, servicing, routine inspections, or regular testing. Additionally, it is strongly recommended to photograph all machinery and attach these images to the written procedures. This provides employees with clear visual references, enhancing their understanding and awareness. Finally, clearly mark the specific locations on the equipment where lockout/tagout must be applied in the photographs.

 

Inspection of Lockout/Tagout Devices and Procedures

In accordance with standards and Occupational Safety and Health Administration (OSHA) requirements, energy control procedures and devices must be inspected at least annually to assess their effectiveness, ensure integrity has not been compromised, and determine whether written procedures require or could benefit from updating.

 

1. Periodic inspections must be conducted by authorized personnel or individuals not involved in the hazardous energy control procedure being inspected.
2. When hazardous energy is controlled using lockout/tagout procedures, periodic inspections must include a joint review by the inspector and authorized personnel of their respective responsibilities within the hazardous energy control procedure being inspected.
3. Employers must document that periodic inspections have been completed. Documentation shall clearly indicate: the machinery or equipment subject to the hazardous energy control procedure, the inspection date, the list of employees involved in the inspection, and the personnel who performed the inspection.

 

Mandatory Training for All Employees

Two specific training programs must be conducted: one for authorized personnel and another for affected employees. The distinction between these two categories is straightforward. Affected employees cannot and do not perform lockout/tagout procedures, but they operate machinery or work in areas where machinery is present. Authorized personnel are capable of and do perform lockout/tagout procedures on machinery requiring repair or maintenance.

 

Authorized Users-All authorized users (employees) must receive training on all hazardous energy control procedures and understand the clearly defined hazards associated with power-driven machinery and equipment during cleaning, maintenance, repair, installation, adjustment, and troubleshooting operations.

 

Affected Personnel - All affected personnel must be trained on the hazardous energy control procedures, including the reasons for their implementation and their purpose. They must understand the prohibition against restarting or re-energizing machinery or equipment that has been locked out/tagged out. They must also be aware of the workplace hazards associated with working around locked-out/tagged-out conditions.

 

We hope this summary and guidance provide valuable insights to help you fully meet the compliance requirements necessary for a complete and effective lockout/tagout program.
