Lockout Tagout

What is Lockout Tagout and What is its Purpose?

Lockout Tagout (29 CFR 1910.147) is an OSHA regulation and important safety practice that protects workers by de-energizing electrical circuits, closing valves, neutralizing extreme temperatures and securing moving parts so hazardous energy isn't re-introduced while equipment is being serviced.

Physically ensuring a machine is inoperable while repairs or adjustments are made with the use of a padlock and a suitable device.

Clearly communicating to workers that equipment is being serviced with labels and tags when lockout is not a viable option or to supplement a lockout device.
Lockout Tagout goes beyond locks, tags and devices. In fact, the majority of citations are a result of improper lockout procedures, program documentation, periodic inspections or other procedural elements.

Lockout Tagout Regulation Requirements

Since OSHA introduced its lockout tagout standard in 1989, it has played a vital role in keeping employees safe on the job.
 Here are the three primary regulatory standards that impact employers in the U.S.

OSHA 29CFR 1910.147 - Control of Hazardous Energy

This standard covers the servicing and maintenance of machines and equipment in which the unexpected energization or start up of the machines or equipment, or release of stored energy, could harm employees. This standard establishes minimum performance requirements for the control of such hazardous energy.

OSHA 29CFR 1910.333 - Electrical Safety

Safety-related work practices shall be employed to prevent electric shock or other injuries resulting from either direct or indirect electrical contacts, when work is performed near or on equipment or circuits which are or may be energized. The specific safety-related work practices shall be consistent with the nature and extent of the associated electrical hazards.

ANSI Z244.1-2003 - Lockout Tagout and Alternative Methods (related article here)

This is a voluntary national consensus standard that represents several industry hazardous energy control best practices and promotes greater flexibility through the use of alternative methods based on risk assessments and application of hazard control hierarchy.

How to Comply with the Lockout Tagout Standard

OSHA requires that, "The employer shall establish a program consisting of energy control procedures, employee training and periodic inspections to ensure that before any employee performs any servicing or maintenance on a machine or equipment where the unexpected energizing, startup or release of stored energy could occur and cause injury, the machine or equipment shall be isolated from the energy source and rendered inoperative."

Your company's energy control program is essential to detailing how you tailor your unique workplace to OSHA's requirements and guidelines. We have outlined six key elements that help define a successful program and are essential to lockout tagout.

These six elements include: Program/policy, procedures, identification, training/audits, lockout devices and sustainability.
