OSHA’s Lockout/Tagout Standard – 29 CFR 1910.147

OSHA’s Control of Hazardous Energy Standard (29 CFR 1910.147) establishes requirements for protecting employees from the unexpected energization, startup, or release of stored energy during servicing and maintenance activities.

Cases involving OSHA’s lockout/tagout standard frequently require analysis of:

• Scope and application of the standard
• Energy control programs
• Written energy control procedures
• Lockout devices
• Tagout devices
• Authorized employees
• Affected employees
• Other employees
• Employee training and retraining
• Periodic inspections of energy control procedures
• Group lockout procedures
• Shift and personnel changes
• Outside contractor coordination
• Alternative methods of protection
• Release from lockout/tagout
• Testing and positioning of equipment
• Stored energy hazards
• Verification of isolation

Many workplace injury cases involve determining whether the employer properly identified hazardous energy sources, developed adequate procedures, provided appropriate training, and ensured effective implementation of energy control measures.

Hazardous Energy Sources Commonly Encountered

Lockout/tagout cases often involve one or more hazardous energy sources, including:

• Electrical energy
• Mechanical energy
• Hydraulic energy
• Pneumatic energy
• Thermal energy
• Chemical energy
• Gravity energy
• Stored or residual energy
• Spring-loaded systems
• Pressurized systems

A comprehensive lockout/tagout analysis often requires identifying all hazardous energy sources associated with a machine, process, or system.

Interplay Between Lockout/Tagout and OSHA Electrical Safety Standards

Many lockout/tagout incidents involve electrical hazards and require analysis of both OSHA’s Control of Hazardous Energy Standard and OSHA’s electrical safety standards.

Depending upon the facts of a case, applicable standards may include:

• 29 CFR 1910.147 – Control of Hazardous Energy
• 29 CFR 1910 Subpart S – Electrical
• 29 CFR 1910.303 – Electrical Systems Design
• 29 CFR 1910.333 – Selection and Use of Work Practices
• 29 CFR 1910.335 – Safeguards for Personnel Protection
• Construction electrical standards under 29 CFR 1926 Subpart K

Many incidents involve questions concerning de-energization, verification of isolation, electrical testing, exposed energized parts, qualified persons, and employee work practices.

OSHA Letters of Interpretation and Enforcement Directives

Proper evaluation of a lockout/tagout case often requires more than simply reading the regulatory text. OSHA’s enforcement policies have evolved through decades of Letters of Interpretation, compliance directives, enforcement guidance, and administrative and court decisions.

Mr. Chambers routinely evaluates:

• OSHA Letters of Interpretation
• OSHA Compliance Directives
• OSHA Field Operations Manual guidance
• OSHA enforcement policies
• Applicable consensus standards
• Industry-recognized practices

These materials often provide critical guidance regarding OSHA’s interpretation and enforcement of lockout/tagout requirements.

Common Lockout/Tagout Issues in Litigation

Cases involving OSHA’s lockout/tagout standard frequently involve allegations concerning:

• Failure to lock out equipment
• Failure to identify all energy sources
• Inadequate written procedures
• Inadequate employee training
• Improper use of tagout systems
• Failure to verify de-energization
• Failure to dissipate stored energy
• Inadequate periodic inspections
• Contractor coordination failures
• Machine guarding deficiencies
• Unsafe maintenance practices
• Electrical safety violations
• Failure to enforce safety procedures

Many cases also involve determining whether a hazard should have been addressed under OSHA’s lockout/tagout requirements, machine guarding standards, electrical safety standards, or a combination of these regulations.
