OSHA Recordkeeping for Electrical Contractors

Electricians usually work on sites run by someone else. Your 300 log covers your own employees and any temporary workers you supervise day to day (29 CFR 1904.31(b)(2)); the general contractor and the other trades log theirs. When the job site isn't one of your establishments, a case goes on the log of the shop or branch the electrician normally works from (1904.30(b)(4)).

Who keeps and files OSHA records

NAICS 238210 is not on OSHA's partially exempt list, so the size rule decides the log (29 CFR 1904.1 (opens in a new tab)) and the filing appendices decide what goes to OSHA (1904.41 (opens in a new tab)).

2024 injury rates for electrical contractors

Cases per 100 full-time workers, as published by BLS for NAICS 23821, electrical contractors and other wiring installation contractors. The TRIR of 1.8 is below the private-industry rate of 2.3.

Your rate is recordable cases × 200,000 ÷ hours worked; the TRIR calculator works it out from your 300A.

Recordable or not: cases from electrical contractors

  • A shock that knocks a worker unconscious is recordable on its own, however short the loss of consciousness. (29 CFR 1904.7(b)(6))
  • A burn treated with a non-prescription ointment at non-prescription strength is first aid; a prescription ointment makes it recordable. (29 CFR 1904.7(b)(5)(ii)(A))

For a case of your own, the recordable checker walks through the same rules.

Electrical Contractors: recordkeeping questions

Does an electrical contractor with 11 employees keep an OSHA 300 log?

Yes. Electrical contractors aren't partially exempt, so the log is required once the company has more than 10 employees at any time during the last calendar year (29 CFR 1904.1). Apprentices and office staff count, and the number is the company's peak for the year.

Do electrical contractors file 300A data with OSHA by March 2?

Yes, from 20 employees per establishment: construction is in appendix A to 29 CFR 1904.41, so a branch with 20 or more employees at any time last year submits its 300A by March 2 through the Injury Tracking Application. Electrical contractors, NAICS 2382, aren't in appendix B, so 300 and 301 case data is not required.

What does the 300A add to the 300 log for an electrical contractor?

The 300 log lists each recordable case within 7 calendar days, with columns for the outcome, the days away or restricted and the injury type (29 CFR 1904.29(b)(3)). The 300A adds them up for the year, adds hours worked and average employees, and is certified by a company executive and posted from February 1 to April 30 (1904.32). The 2024 average for electrical contractors was 1.8 recordable cases per 100 full-time workers, below the private-industry 2.3.
