Programmes Efficace de Verrouillage et d'Etiquetage

Energy sources including electrical, mechanical, hydraulic, pneumatic, chemical, thermal, and others can be hazardous to workers. OSHA’s Title 29 CFR 1910.147, and NFPA 70E article 120, are general industry standards focused on addressing the practices and procedures necessary to disable machinery or equipment. Focused on preventing unexpected energization or release of hazardous energy during a maintenance activity that can result in serious injury or death.


Lockout is the placement of a lockout device on an energy isolation device, in accordance with an established procedure, ensuring that energy isolation device and equipment being controlled cannot be operated until lockout device is removed.

Tagout is the placement of a tagout device on an energy isolating device, in accordance with an established procedure, to indicate that energy isolating device and equipment being controlled may not be operated until tagout device is removed


LOTO Program Development

The first step is to create a written program that documents the LOTO energy control process within your facility. Our experienced professionals have written LOTO programs in nearly every industry. Each program is custom developed for compliance with the applicable OSHA regulations and standards as well as your company’s specific requirements and policies.


An Effective Lockout/Tagout Energy Control Program:


  • Energy Control Procedures (ECP) for affixing appropriate lockout devices and/or tagout devices to energy isolation devices (SEE IMAGE BELOW)

  • Trains on hazards or hazardous energy and lockout/tagout procedures, policies, and equipment

  • Conducts periodic audits of the system (at least annually).

A Lockout/Tagout procedure should include the following 6 steps:

  1. Preparation: This is a planning step. An authorized employee understands the types of hazardous energy and specific hazards that need to be controlled, and the means for controlling them.

  2. Shutdown: The machine or equipment that will be affected are shut down, and any affected employees is informed.

  3. Isolation: After the shutdown, the machine or equipment is isolated from any source of energy.

  4. Lockout/Tagout: After isolation, the authorized employee will attach lockout and/or tagout devices to each energy isolation device to ensure that it cannot be moved to the unsafe position. The tag must include the name of the person who performed the lockout and additional information.

  5. Stored Energy Check: Even after lockout / tagout is performed, it is critical to verify if any hazardous stored or residual energy is still within the machine or equipment. If so, it must be relieved, disconnected, restrained, or made non-hazardous in some other way.

  6. Isolation Verification: As a final step, an authorized employee verifies and confirms that the machine or equipment has been properly isolated and de-energized.

Annual Audits / Reviews

Annual Audit / Reviews are used to verify that ECPs are accurate, and that employees are able to demonstrate proper energy isolation of equipment to perform servicing and maintenance. SEAM's health and safety professionals can also complete an evaluation of authorized employees as an added service.

LOTO Compliance Gap Assessment

For companies that have implemented a LOTO program, we offer a LOTO Compliance Gap Assessment (CGA). Our experienced team will perform an in-depth review of your written LOTO program, ECPs, employee interviews, and compliance with applicable OSHA Regulations and Consensus Standards. Through the LOTO CGA process, you will have a detailed report of where your LOTO program stands, both for compliant items as well as for any gaps identified, with recommendations to close the gaps.

An effective LOTO approach will assist your company’s compliance with the elements of the LOTO regulation and give your employees a set of tools to work safely.
