Construction Incident Reporting: What to Do in the First Hour, Day and Week
When an incident happens on a construction site: get care for the injured person, make the area safe, notify the superintendent and the injured worker's employer right away, preserve the scene, and record the facts the same day (who, what, where, when, witnesses, photos). The employer must report a work-related fatality to OSHA within 8 hours and an in-patient hospitalization, amputation or loss of an eye within 24 hours (https://www.osha.gov/report). Then investigate root cause and assign corrective actions with owners and due dates.
This is general guidance. Follow your company safety program, your state's rules and your counsel.
The first hour
- Care. Call 911 when needed. Give first aid within training.
- Make it safe. Stop the work, de-energize, barricade. Do not create a second victim.
- Notify. Superintendent, the injured worker's foreman and employer, the general contractor safety lead.
- Preserve the scene. Leave equipment and materials in place unless they create more danger. Take photos and video from several angles before anything moves.
- Identify witnesses. Get names and phone numbers before people leave.
The first day
Record the facts
- Date, time and exact location (level, gridline, room)
- Injured worker's name, employer, trade
- Task being performed and equipment involved
- What happened, in plain sequence
- Injury type and body part
- Treatment given and where the worker went
- Witnesses and short statements in their own words
- Conditions: weather, lighting, housekeeping
- Photos
Decide on outside reporting
The injured worker's employer determines OSHA reporting:
| Event | Report to OSHA within | Source |
|---|---|---|
| Fatality | 8 hours | 29 CFR 1904.39 |
| In-patient hospitalization | 24 hours | 29 CFR 1904.39 |
| Amputation | 24 hours | 29 CFR 1904.39 |
| Loss of an eye | 24 hours | 29 CFR 1904.39 |
OSHA notes that emergency room treatment alone is not an in-patient hospitalization. Details and how to report: https://www.osha.gov/report
Also check your owner contract and insurance carrier; many require notice within hours.
Put it in the daily report
The day's report should state that an incident occurred, the basic facts, and that an incident report is in progress. Keep the narrative factual and avoid guessing at cause on day one.
The first week
Investigate root cause
Ask "why" until you reach something you can fix. A cut hand might trace back to a dull blade, which traces back to no blade-change routine, which is the actual fix.
Assign corrective actions
Each action needs an owner, a due date and a way to verify it is done. See corrective actions in construction safety.
Share lessons
Share what happened and what changed (without blame or personal details) at the next crew huddle and the weekly sub meeting.
Recordkeeping
Employers covered by OSHA recordkeeping must decide whether the case is recordable on the 300 Log and keep the 300 Log, annual summary and 301 forms for five years after the end of the calendar year (https://www.osha.gov/laws-regs/regulations/standardnumber/1904/1904.33).
Sample incident report entry
Incident #014, Thursday 10:20 AM, Westgate Senior Living, Building 2, Level 2 unit 214. Injured: carpenter, Ridgeline Framing. Task: cutting sheathing with utility knife. What happened: Knife slipped while cutting toward hand holding the sheet. Laceration to left palm. Treatment: First aid by Ridgeline foreman, sent to urgent care at 10:45 AM for evaluation, 4 stitches, returned to work 1:30 PM with no restrictions. Witnesses: J. Morales (Ridgeline), A. Chen (Ridgeline). Conditions: Indoor, adequate light, cluttered cut area. Immediate actions: Area cleaned, cut table set up on Level 2. Corrective actions: Ridgeline to provide cut-resistant gloves for all sheathing cuts by Friday (owner: Ridgeline foreman). Knife safety review with Ridgeline crew Monday (owner: general contractor super). Verify at Monday walk. Photos: 5.
Near misses count too
Most sites get far fewer near-miss reports than actually happen. Treat them as free lessons. See near-miss reporting in construction.
Roles on a multi-employer site
On a general contractor-run job, several parties have reporting duties at once. Sort them out before the first incident, not during it.
| Role | Typical responsibility |
|---|---|
| Injured worker's foreman | Immediate care, notify own employer and general contractor superintendent |
| Injured worker's employer | OSHA reporting and recordkeeping, workers' compensation |
| General contractor superintendent | Secure the area, notify general contractor safety and PM, document in the daily report |
| General contractor safety lead | Investigation support, owner and insurer notice per contract |
| Project manager | Owner notification as the contract requires |
Put the contact list and these roles in the site safety plan and review them at the subcontractor kickoff meeting.
Mistakes to avoid
- Moving equipment or cleaning up before photos
- Waiting until end of shift to write anything down
- Guessing at cause in the first report
- Letting witnesses leave without contact details
- Treating first aid cases as not worth recording
Make incident reporting as fast as a text
The first report on an incident is usually a phone call or a text anyway. Cascade is SMS-first field intelligence for general contractors and subcontractors: superintendents and foremen text in their day, along with their subs, and Cascade builds the daily report, including safety incidents and corrective actions with photos and follow-up. Coverage: Daily reports, manpower and hours by sub, photos, toolbox talks, pre-task plans (JHA), safety incidents and corrective actions, project + schedule planning, automatic sub reminders, analytics and plain-English answers.
Subcontractor access is free. See why Cascade and SMS daily construction reports. Free onboarding and integration, a one-month pilot on the general contractor plan with no contract lock-in, and a price below Raken, Procore and ACC, guaranteed.
Frequently asked questions
When must a construction incident be reported to OSHA?
Under 29 CFR 1904.39, employers must report a work-related fatality within 8 hours and an in-patient hospitalization, amputation or loss of an eye within 24 hours. State plan states may have their own rules.
Who reports an incident involving a subcontractor's worker?
The employer of the injured worker is responsible for OSHA reporting and recordkeeping. On a general contractor site, subcontractors should also report to the general contractor immediately so the general contractor can secure the scene, document it and follow site and owner requirements.
How long must injury records be kept?
OSHA requires the 300 Log, annual summary and 301 incident reports to be kept for five years following the end of the calendar year they cover (29 CFR 1904.33).
Should first-aid-only injuries be documented?
Yes, on the daily report and in your internal incident log, even if they are not OSHA recordable. They help spot patterns and show your program works.
