OSHA recordkeeping for contractors

Most construction companies with more than 10 employees must keep the OSHA 300 log, 301 incident reports, and the 300A annual summary under 29 CFR Part 1904. Every employer, even a small one, must report a fatality within 8 hours and an inpatient hospitalization, amputation, or loss of an eye within 24 hours.

OSHA recordkeeping for contractors comes down to four duties under 29 CFR Part 1904: record each work-related injury or illness that meets the recording criteria on the OSHA 300 log and a 301 incident report within 7 calendar days, post the 300A summary from February 1 to April 30, keep the records for 5 years, and report the most serious events to OSHA within hours. Construction is not on the list of partially exempt industries, so if your company had more than 10 employees at any time last year, the rules apply.

The rules are not hard. What trips up contractors is the job-site reality: crews spread across a dozen short projects, temp laborers, subs on the same site, and a foreman who treats an injury with a bandage and never tells the office.

Who has to keep OSHA injury records

Under 29 CFR 1904.1, a company with 10 or fewer employees at all times during the last calendar year is partially exempt. The count is company-wide peak employment, not per job site. Cross 10 for a single week during a busy summer and you keep records for the next year. Even exempt employers must still report fatalities and the other severe events described below.

Temps, leased workers, and subcontractor employees

29 CFR 1904.31 turns on day-to-day supervision. If you supervise a staffing agency's laborer day to day, the injury goes on your log. If a subcontractor directs its own crew, the sub records its own injuries. If your superintendent directs a sub's worker day to day, you record it. Seasonal workers on your payroll are covered like anyone else.

What makes a case recordable

Under 29 CFR 1904.4, you record a case when it is work-related, it is a new case, and it meets a recording criterion. The general criteria in 1904.7 are death, days away from work, restricted work or job transfer, medical treatment beyond first aid, loss of consciousness, or a significant injury or illness diagnosed by a physician or other licensed health care professional. Separate rules cover needlesticks, hearing loss, tuberculosis, medical removal, and musculoskeletal disorders.

First aid is a defined list. It includes non-prescription medication at non-prescription strength, cleaning and covering surface wounds, hot or cold therapy, non-rigid supports like elastic wraps, removing splinters by simple means, finger guards, and drinking fluids for heat stress. Stitches, a prescription, or a rigid splint for support take the case past first aid.

How construction sites fit the establishment rules

OSHA logs are kept by establishment. Under 29 CFR 1904.30, short-term establishments expected to last less than a year do not need separate logs. You can keep one log for all of them, or one per division or region. Records can live at headquarters if each case reaches the central office within 7 calendar days and you can produce the records on time when asked. Employees who travel or have no fixed location must be linked to one of your establishments for recordkeeping. In practice, most small and midsize contractors keep a single company log for field work plus a separate one for the shop or yard if it is a permanent establishment.

Severe injury reporting

29 CFR 1904.39 requires reporting a work-related fatality within 8 hours, and an inpatient hospitalization, amputation, or loss of an eye within 24 hours. Report by phone or in person to the nearest OSHA area office, by calling 1-800-321-OSHA (1-800-321-6742), or through OSHA's online reporting application. Voicemail, fax, or email does not count. Motor vehicle crashes on a public road are reportable only if they happen in a construction work zone, which catches road and utility contractors.

Electronic submission

29 CFR 1904.41 requires establishments with 20 to 249 employees in industries listed in Appendix A to submit the 300A electronically each year, and Construction (NAICS 23) is on Appendix A. Establishments with 100 or more employees in Appendix B industries must also submit 300 and 301 data. In construction, Appendix B lists NAICS 2381 (foundation, structure, and building exterior contractors). Submissions are due by March 2 of the following year and must include the company's legal name and EIN.

Who can ask to see the records

Records have to be retrievable fast. Under 29 CFR 1904.35, a current or former employee, a personal representative, or an authorized employee representative who asks for the 300 log must get a copy by the end of the next business day. Under 1904.40, when an OSHA compliance officer asks for Part 1904 records, you have 4 business hours to produce them. A log that lives in one person's truck does not meet either deadline.

Worked example: a 45-person concrete contractor

Say a concrete contractor (NAICS 2381) peaks at 45 employees. It keeps a 300 log because it exceeds 10 employees. In April, a finisher cuts a hand on rebar and gets four stitches: recordable as medical treatment. In July, a laborer gets a heat cramp and is treated with fluids and rest: first aid, not recordable. In October, a temp from a staffing agency, directed daily by the company's foreman, sprains an ankle and the doctor restricts him to light duty for 10 days: recordable on the contractor's log.

At year end, an officer certifies the 300A, it goes up on the shop bulletin board by February 1, and because the company has 20 to 249 employees in construction, the 300A is submitted electronically by March 2. It does not reach the 100-employee threshold for submitting 300 and 301 data.

Mistakes to avoid

  • Counting employees per site instead of company-wide when deciding if you are exempt.
  • Leaving supervised temp workers off your log.
  • Waiting for the workers comp claim to decide whether a case is recordable. The OSHA criteria are separate.
  • Missing the 8-hour and 24-hour reporting windows because nobody in the field knows they exist.
  • Discouraging reports. 29 CFR 1904.35 requires a reasonable reporting procedure and bars retaliation against employees who report injuries.

Frequently asked questions

Do construction companies have to keep an OSHA 300 log?

Yes, unless the company had 10 or fewer employees at all times during the last calendar year. Construction is not one of the partially exempt industries, so the size exemption is the only way out.

How long do I have to record an injury on the OSHA 300 log?

Seven calendar days from receiving information that a recordable injury or illness occurred, under 29 CFR 1904.29.

Do I need a separate OSHA log for every job site?

No. Sites expected to last less than a year are short-term establishments, and 29 CFR 1904.30 lets you keep one log for all of them or group them by division or region.

Who records an injury to a subcontractor's employee?

Whoever supervises that worker day to day. Normally that is the subcontractor. If your superintendent directs the worker's daily work, you record it.

When is the OSHA 300A due?

Post it from February 1 to April 30 of the year after the year covered. If your establishment must submit electronically, the deadline is March 2.
