Power Generation & Distribution Work (1910.269)

OSHA 1910.269 sets the rules for the people who build and maintain the electric grid: power plants, substations, transmission and distribution lines. It builds on general electrical rules with stricter requirements for high voltage and line work.

• Utility Workers
• Linemen
• Contractors

Who it covers

• Operation and maintenance of generating plants, substations and electric lines owned by utilities or others.
• Construction of transmission and distribution lines is covered by 1926 Subpart V, which is closely aligned with 1910.269.
• Line-clearance tree trimming near energized lines is also covered. See Tree Work Near Lines.

Core requirements

• Training: workers must be trained and competent, and tested on the specific work. Qualified workers know how to separate energized parts from themselves. See Qualified vs. Unqualified Persons.
• Job briefing: before each job, the person in charge briefs workers on hazards, work procedures, special precautions, energy source controls and PPE.
• De-energizing and grounding: lines and equipment are isolated, locked or tagged, tested dead, and grounded where required. See Lockout/Tagout and Grounding & Bonding.
• Minimum approach distances: set by voltage, so workers and tools stay far enough away from energized parts. See Overhead Power Lines.
• Fall protection: required when working from poles, towers and structures, including pole climbing, with specific rules for harnesses and lanyards. See Personal Fall Arrest Systems.
• Rescue: employees trained in first aid and CPR, and in pole-top and manhole rescue.
• Arc flash: the employer must assess arc hazards and provide arc-rated clothing for exposed workers. See Arc Flash.

Field safety checklist

• Hold the job briefing and write it down for longer jobs
• Confirm what is energized and what is not, using test equipment
• Install protective grounds and keep them until work is done
• Use insulated tools, rubber gloves and sleeves that are tested on schedule
• Inspect pole condition before climbing, and use fall protection
• Keep vehicles and cranes clear of lines
• Know the emergency plan and who is trained to rescue
