Workplace Safety & OSHA Compliance Training
Advance your knowledge with Workplace Safety & OSHA Compliance Training through a self-paced program with certificate included.
Knowing how to report construction site injuries correctly is a legal obligation, not a best practice. Miss OSHA's 8-hour deadline for reporting a worker fatality, and you face a fine of up to $165,514. File your injury log late or leave fields blank, and every gap is its own citation. This guide covers every requirement — the right forms, the right deadlines, and the step-by-step procedure supervisors need to follow from the moment an injury happens to the day the annual summary comes down.
Construction records the highest number of workplace fatalities of any U.S. industry. According to the Bureau of Labor Statistics, 1,069 construction workers died on the job in 2024 — roughly one death every eight hours. The industry's fatality rate of 6.1 per 100,000 full-time workers is nearly double the all-industry average of 3.5, which is why OSHA enforces 29 CFR Part 1926 more aggressively than most general industry standards.
29 CFR Part 1926 governs construction safety — including scaffolding, fall protection, excavations, and electrical work on active job sites. 29 CFR Part 1904 governs injury and illness recordkeeping for all covered employers. Part 1926 defines what a safe site looks like; Part 1904 defines how every lapse gets documented and reported.

OSHA sets three different reporting deadlines, each triggered by a different level of injury severity. Supervisors and safety officers need to know all three before an incident occurs, not after.
A work-related fatality must be reported to OSHA within 8 hours of the employer learning about it. OSHA provides two reporting channels: the 24-hour hotline at 1-800-321-OSHA and an online reporting form at osha.gov/report. The clock starts when the employer — not just the on-site supervisor — becomes aware of the death. Reporting to a supervisor who does not immediately pass the information up the chain does not stop the 8-hour window from running.
A work-related inpatient hospitalization, amputation, or loss of an eye must be reported to OSHA within 24 hours. The same two channels apply — the OSHA hotline or the online form. One common mistake construction employers make is confusing "in-patient hospitalization" with any trip to an emergency room. An ER visit for evaluation and release does not trigger the 24-hour requirement. An admission to the hospital for overnight care does.
Reportable injuries must be reported to OSHA by phone or online within 8 or 24 hours. Recordable injuries go on OSHA Form 300 within 7 calendar days. Not every recordable case is reportable — a fracture, stitches, or a restricted-duty assignment creates a Form 300 entry but does not trigger a call to OSHA. Every reportable incident is also recordable.

29 CFR Part 1904 requires construction employers to maintain three forms. Each serves a different purpose, and a missing or incomplete form is a separate citation.
OSHA Form 300 — The Injury and Illness Log records every work-related injury or illness that meets recordable criteria. Entries must be made within 7 calendar days of learning about the case. The log captures the injured worker's name, job title, date of injury, where it happened, a description of the injury, and the outcome — days away from work, restricted duty, transfer, or other result.
OSHA Form 301 — The Incident Investigation Report provides detailed background on each recordable case. Form 301 captures how the injury happened, what the worker was doing, what object caused the injury, and what the medical treatment involved. Some employers substitute a workers' compensation first report of injury for Form 301, but only if it captures all of the fields OSHA requires.
OSHA Form 300A — The Annual Summary totals the prior year's cases and must be signed by a company executive. Form 300A must be posted in a visible location at each job site from February 1 through April 30 each year. OSHA requires the posting even in years with zero recordable incidents.
Construction employers with 10 or fewer employees are exempt from routine OSHA recordkeeping — Forms 300, 300A, and 301 — but not from fatality and severe injury reporting. Those phone-or-online obligations apply to every employer regardless of size. Construction is classified as a high-hazard industry, so the partial exemption available to low-hazard NAICS codes does not apply.
A compliant construction incident report contains eight elements: the date and time of the incident, the exact location on the jobsite, the full name and job title of the injured worker, a description of the injury or illness, the equipment or materials involved, witnesses' names and contact information, a description of what the worker was doing when the incident occurred, and the immediate actions taken. Vague entries like "worker fell and hurt their back" do not meet OSHA Form 301 standards. Specific entries, such as "worker fell approximately 8 feet from scaffolding on the third-floor north wall while installing formwork, landing on concrete below," create a defensible record.
A factual, specific incident report is also the strongest protection a company has during an OSHA inspection. Inspectors watch for reports written after the fact to minimize injuries or dodge recordability. Reports completed within hours, with consistent witness accounts and attached medical documentation, show good faith. Supervisors building a structured approach to documentation and OSHA recordkeeping often start with the Workplace Safety & OSHA Compliance Training course, which covers legal requirements alongside the documentation practices that hold up under inspection.
A construction incident follows four time-bounded stages, each with specific required actions.
Immediate response (within the first hour). Secure the scene to prevent a second injury. Get medical help for the injured worker. Notify the site supervisor and the company safety officer. Do not move equipment or alter the scene until OSHA has been notified of a fatality or severe injury.
Within 8 or 24 hours. If a worker died or was hospitalized, amputated, or lost an eye, call OSHA at 1-800-321-OSHA or report online at osha.gov/report within the applicable deadline.
Within 24 to 48 hours. Complete the internal construction incident report (OSHA Form 301 or an equivalent). Interview witnesses while accounts are fresh and photograph the scene before conditions change.
Within 7 calendar days. Enter the case on OSHA Form 300 if it meets recordable criteria. Recordable cases include any work-related injury resulting in days away from work, restricted duty, medical treatment beyond first aid, loss of consciousness, or diagnosis of a significant illness by a healthcare professional.
Falls are the most common cause of death in construction, accounting for 33.5% of all construction fatalities in 2024, per BLS data. OSHA's Fatal Four — falls, struck-by incidents, electrocutions, and caught-in/between accidents — together account for 58.6% of all construction worker deaths. Eliminating those four hazard categories alone would save approximately 625 workers' lives per year.
Falls, struck-by injuries, and electrocutions are frequently recordable and sometimes reportable from the same incident. A worker who falls from scaffolding and is hospitalized triggers a 24-hour OSHA report and a Form 300 entry within 7 days. Musculoskeletal injuries — sprains, strains, and back injuries — are the most common non-fatal recordable cases. They become recordable when treatment goes beyond first aid or a single diagnostic visit to a healthcare provider.
OSHA's anti-retaliation provisions under Section 11(c) of the Occupational Safety and Health Act prohibit the discharge, demotion, or other penalty of a worker for reporting a work-related injury. A worker cannot be disciplined for filing a workers' compensation claim or asking for an OSHA inspection. Workers who believe they faced retaliation have 30 days to file a complaint with OSHA.
OSHA's recordkeeping rule at 29 CFR 1904.35 prohibits employers from using drug testing or safety incentive programs in ways that discourage injury reporting. A blanket post-incident drug test policy may be acceptable if it applies consistently, but a zero-incident bonus program that discourages workers from reporting real injuries violates 29 CFR 1904.35. OSHA has cited both types of programs when they appear to suppress reporting.

OSHA typically responds to a fatality report with an on-site inspection within 24 hours. Severe injury reports — hospitalizations, amputations, eye loss — may result in a site inspection or in closure via a phone call and written documentation, depending on available resources. Recordkeeping inspections are triggered during programmed visits, fatality investigations, or employee complaints.
OSHA's maximum penalties in 2026 are $16,550 per serious violation and $165,514 per willful or repeat violation. Recordkeeping failures — late Form 300 entries, missing Form 300A postings, incomplete Form 301 records — typically draw other-than-serious citations with a maximum of $16,550 each. Late reporting of fatalities is treated as a serious violation. A company that previously missed the same reporting deadline and is cited again faces a willful violation of up to $165,514 for one missed phone call.
Twenty-two states and territories operate their own OSHA State Plans, which must meet or exceed federal requirements. Construction employers in those states follow State Plan rules, which often impose stricter standards, shorter deadlines, or higher fines.
California's Cal/OSHA requires construction employers to report any serious injury, illness, or death to the nearest district office immediately — not within 8 hours, but immediately upon learning of it. Cal/OSHA's maximum penalty for a serious violation is $25,000 per violation, compared to $16,550 under federal OSHA. Washington's Department of Labor & Industries requires a 24-hour report for any work-related hospitalization. Michigan's MIOSHA follows federal timelines but has its own citation and investigation process. Employers in multiple states need a separate reporting checklist for each State Plan jurisdiction.
