29 CFR 1910.147
Control of hazardous energy for covered servicing and maintenance. Includes energy-control procedures, training, periodic inspection, group LOTO and shift-transition provisions. Scope exclusions must be checked.
Hazardous-energy control depends on more than a procedure or a completed checklist. Electrical assets, work boundaries, designated personnel, verification and historical evidence must be understood together.
ECOS's intended architecture connects program governance with the electrical context behind each work activity. The digital record supports the process; it does not perform the field work.
Identify the customer-adopted requirement, source edition and approved procedure.
Associate physical assets, potential sources, work zones and documented boundaries.
Record assigned roles, approval responsibility and personnel handover context.
Link field-entered verification, custody, inspection and transition history.
A facility can be operating while a particular crew performs construction. Commissioning, modifications and maintenance also involve different responsibilities. A lifecycle label alone cannot determine legal applicability.
Work on newly installed or modified electrical infrastructure can involve facility circuit controls or specialized utility T&D construction requirements. Scope, equipment and employer responsibilities need to be evaluated before procedures are selected.
These examples are orientation aids, not an automated legal determination. Confirm which provisions apply with the employer's authorized safety and legal personnel.
These resources support program research and requirements mapping. Federal regulations, consensus standards and contract specifications have different legal standing; customer adoption and applicable editions must be verified.
Control of hazardous energy for covered servicing and maintenance. Includes energy-control procedures, training, periodic inspection, group LOTO and shift-transition provisions. Scope exclusions must be checked.
Electrical safety-related work practices for covered electrical utilization work, including provisions for deenergized circuits, lockout/tagging and verification.
Construction requirements for tagging controls and deenergized equipment or circuits, including points at which the circuit could be energized.
Specialized electric power transmission and distribution construction requirements, including clearances, deenergizing, grounding, and substations.
Requirements for covered electric power generation, transmission and distribution operations and maintenance, including employer and employee coordination duties.
U.S. Army Corps of Engineers safety and occupational health requirements, including Chapter 12 hazardous-energy control. The 15 March 2024 manual may be contractually applicable on covered projects.
Electrical safety-related work practices, risk assessments, and electrically safe work conditions. NFPA lists a 2027 edition; the edition applicable to a customer program may differ.
Hazardous-energy control using lockout, tagout and alternative methods. The 2024 edition revises the 2016 (R2020) edition; alternative methods require case-specific technical evaluation.
Reference summaries are not reproductions of standards, legal advice, regulatory endorsements, or assertions of ECOS certification. This page does not determine which framework governs a particular employer or job.
The public ECOS Scenario Explorer depicts fictional equipment relationships. A colored status or linked record does not establish present voltage, physical isolation, grounding or permission to work.
Applicable regulations, approved procedures, qualified personnel and training remain employer-controlled responsibilities.
Isolation, device placement, testing, protective grounding and work boundaries are established through authorized field practices.
ECOS is designed to associate submitted records with the equipment, work activity and responsible person; digital records do not replace verification.
Bring electrical contractors, commissioning teams, facility owners and EHS leaders into the same conversation about responsibility and traceable evidence.
