Workplace Incident Report: How to Document an Accident with Certified Evidence

What to do in the first minutes after a workplace accident

Help the injured person and make the area safe first, then leave the scene exactly as it is until someone has recorded it.

Call emergency services when the injury needs them, give first aid and stop whatever caused the harm: isolate the machine, cut the power, close off the area. ISO 45001 opens clause 10.2 the same way: react to the incident and take action to control it (ISO/TC 283, ISO 45001 FAQ).

Once nobody is at risk, the priority changes. The ILO code of practice on recording and notification asks the employer to keep the site undisturbed until the investigation begins (paragraph 10.2.4). If first aid or safety forces someone to disturb it, a competent person should record the site before any intervention, “including where necessary photographs, drawings and the identities of eyewitnesses” (paragraph 10.2.5). Then notify the safety manager, the workers’ representatives, the insurer and, where national law requires it, the competent authority.

A few habits destroy evidence for good:

• restarting, repairing or adjusting the machine before it has been recorded;
• cleaning up spills, debris or broken parts;
• moving tools, ladders, PPE or materials when safety does not require it;
• leaving witness statements until the next day;
• treating photos forwarded in a chat as the only record of the scene.

Workplace incident report: who files it, when, and what it records

The employer records and reports the accident; national law sets the deadline and the authority, while international standards describe what the report has to contain.

A workplace incident report is the employer’s written record of an occupational accident, a dangerous occurrence or a near miss: who was involved, what happened, where and when, the injuries and the first actions taken. TrueScreen gives that record what it usually lacks, images of the scene whose time of capture anyone who receives them can check.

The ILO Protocol of 2002 to the Occupational Safety and Health Convention defines an occupational accident as “an occurrence arising out of, or in the course of, work which results in fatal or non-fatal injury” (Article 1). Under the Protocol, national procedures make employers responsible for recording occupational accidents, keeping the records for prevention and refraining from retaliation against a worker for reporting (Article 3).

Notification is a separate duty. The Occupational Safety and Health Convention, 1981 (No. 155) calls for procedures for notification “by employers and, when appropriate, insurance institutions” (Article 11(c)), and the Protocol leaves “the time limits for notification” to national procedures (Article 4). Check the deadline in the national law that applies to you, usually that of the country where the accident happened.

What the report should contain

Article 5 of the Protocol sets out what a notification contains: the enterprise, establishment and employer, the injured persons and the nature of their injuries, and the workplace and circumstances of the accident. An internal report worth having also records:

• the date, time and exact location;
• the people involved and the witnesses present;
• the task, equipment and materials in use;
• the sequence of events as each witness describes it;
• the first aid given and the actions taken to make the area safe;
• the evidence collected and where it is kept.

Clause 10.2 of ISO 45001 asks the organization to “deal with the consequences” of an incident (ISO/TC 283 FAQ); a complete report supports that step.

Why the sequence of events gets disputed

Everyone who reviews an accident later rebuilds the scene as it was in the first minutes, and that is the moment most companies record worst.

Labor inspectorates look hardest at serious cases: Convention 155 calls for inquiries where occupational accidents “appear to reflect situations which are serious” (Article 11(d)). The insurer decides whether the injury is work-related and covered, and in a damages claim or criminal case a judge weighs each party’s version. In workplace safety inspections the questions are always concrete: where the guard was, whether the harness was clipped on, what the floor looked like.

Work accidents cause about 330,000 deaths a year and 395 million workers suffer non-fatal work injuries, according to ILO estimates published in 2023, and every serious case sends someone back to the same first hour.

Two hypothetical cases show how fast a scene loses its value. A worker falls from a scaffold: the company says the guardrail was in place and the worker had unclipped his harness, while the worker says a section of guardrail had been missing since the morning. By the afternoon the scaffold has been completed, and the only images are three shots from a supervisor’s phone. In the second case an operator’s hand is crushed in a press, and maintenance repairs the guard interlock the next day so production can restart. From then on nobody can show whether the interlock had been bypassed, had failed or was working.

In neither case does the doubt go away: when the sequence of events stays uncertain, the uncertainty weighs on the claim, the inspection or the court case, and it can weigh against either side.

Which evidence to collect, and where it weakens

Each kind of evidence has a weak point the other side will look for, usually the gap between when it was created and the moment it claims to show.

A photo forwarded through a messaging app often loses its original metadata on the way, so nobody can say which phone took it or when, whereas a photo captured with TrueScreen is created inside a controlled acquisition and its report states the certified time of capture. A file imported later from the phone gallery gets a certain date from the moment of import, which helps, but it is not a forensic acquisition of the scene.

Certified workplace safety records made before the accident, such as inspection photos or maintenance checks, show the prevention measures on a certified date, with any later change to the files detectable. On the day itself, a certified video shows where the machine guard was before anyone refitted it, which is usually the first detail to disappear.

How TrueScreen certifies the incident scene at the source

TrueScreen certifies the incident scene at the moment it is recorded, so the photos, video and statements in the report carry their own proof of when and how they were captured.

With the TrueScreen App, the supervisor or safety manager captures photos, video and audio live at the scene. The forensic acquisition prevents alteration while it is under way and makes any later change detectable. Photos are marked as live captures, video is certified in full, and every file gets a SHA-256 fingerprint. Location is recorded when the workflow is set to capture it (it can be off, optional or mandatory), and the device clock is checked, with any drift declared in the report. Certification needs a network connection, so check coverage in basements or remote yards.

Witness statements and documents join the same record through TrueFlow, a guided collection opened from its own link. A colleague who saw the accident can give a statement while it is fresh, in their own voice, and sign it with TrueScreen’s digital signature service, without an account when the flow does not require a login. The link can be set to single use, can carry an expiry date and can require an SMS code.

Every certification produces a package with a sealed XML file, a PDF report and the original files. Only as the last step does TrueScreen apply a qualified electronic seal and a qualified timestamp under the eIDAS framework (Regulation (EU) No 910/2014): the seal carries a legal presumption of the integrity and origin of the data, and the qualified timestamp fixes the time of the certification. Content certified with TrueScreen carries full legal and evidentiary value worldwide, and its weight in a given case is for the judge to assess. Anyone can verify the package without TrueScreen and without trusting whoever hands it over, for instance with the EU’s public DSS validator.

A certification attests how and when content was captured, not what happened: it does not prove the sequence of events, the causes, the truth of a statement or who the people on camera are, and a staged scene would be certified as an authentic recording of a staged scene. It does not replace the accident investigator or a technical expert, it cannot promise the outcome of an inspection, a claim or a trial, and it does not make a company compliant with ISO 45001 or any safety law.

Picture a hypothetical workshop where an operator’s hand is crushed in a press. After first aid, the safety manager records the press, the removed guard and the controls with TrueScreen before maintenance touches anything, and the supervisor sends the two colleagues present a statement flow with a voice recording and a signature. The package goes to the inspector and the insurer as it is, and each can check it alone.

How to write an incident report after a workplace accident, step by step

A report that holds up follows the order of events: safety, scene, witnesses, records, notification and one package that others can verify.

1. 1

   Make the area safe and help the injured person

   Give first aid, call emergency services when needed, stop the equipment and close off the area. Note the time of the accident and the time help arrived, because those two times anchor the rest of the report.

2. 2

   Certify the scene before anything is touched

   Record the place, the machinery and the equipment as they are: wide shots of the whole area first, then guards, controls, ladders, anchor points, PPE, floor and lighting. With the TrueScreen App you can certify a photo of the point where the worker fell before the area is cleaned up, then walk the scene on video.

3. 3

   Collect statements while memories are fresh

   Talk to each witness separately within the first hours and ask what they saw and heard, not what they think caused it. A certified audio recording fixes the witness’s words as they are spoken, and a TrueFlow sent to their phone can add a written statement and a signature to the same record.

4. 4

   Gather the company’s own records

   Pull the risk assessment, maintenance and inspection logs, training records and PPE issue records. Scan paper documents into the certified record as they stand on the day, so the version in force that day is documented.

5. 5

   File the report and notify within the national deadline

   Complete the internal workplace incident report and send the notification that national law requires to the competent authority and the insurer. The ILO Protocol of 2002 leaves time limits to each country (Article 4), so check the local rule.

6. 6

   Keep one package for inspectors, insurers and the court

   Keep the report, files, statements and records together. With TrueScreen, inspectors, insurers and judges receive the same package and can verify the certification on their own, without taking anyone’s word for it. Record near misses with the same care: ISO 45001 asks you to determine whether similar incidents have occurred (clause 10.2), and the next investigation may depend on them.
