Workplace accidents: mistakes to avoid

10 September 2026

Doubt about the nature of an accident is never a reason not to report it. The deadlines, the traps, and what to do within the hour.

One sentence sums up this article: never skip reporting a workplace accident, even where you have doubts about its nature.

The reason is simple. Characterisation (workplace accident, commuting accident, or neither) does not belong to the employer: it is for the social security institution, which investigates the file. By not reporting because of doubt, the employer does not settle the question: it deprives the victim of the investigation and exposes itself alone to the consequences.

1. What is a workplace accident?

A workplace accident is any accident, whatever its cause, occurring by reason of or on the occasion of work.

Two phrases carry the whole definition. "Whatever its cause": the victim's clumsiness, carelessness, or the absence of a third party's fault do not remove the characterisation. "On the occasion of work": the accident need not occur during the task itself; it is enough that it relates to work, a business trip, an assignment, a movement within the establishment. Social Security Code, Article 62 (French).

2. The commuting accident

An accident occurring on the journey between home and workplace is also recognised, provided the route was not interrupted or diverted for a reason dictated by personal interest.

This is where most doubts arise: a stop to drop off a child, a detour to a shop, a car share. Such situations are assessed case by case, and that is precisely why they should not be settled internally. Doubt is reported, not resolved. Social Security Code, Article 63 (French).

3. The deadlines

Two distinct obligations, two short deadlines:

WhoWhatDeadline
The employee (or their dependants)Inform the employer48 hours after the accident, save force majeure or a justified legitimate reason
The employerReport the accident to the INPSImmediately, and at the latest within 48 hours

The second deadline does not start at the end of the internal enquiry: it runs from the accident. A report submitted after verifications is still late, however well prepared. Social Security Code, Articles 63 and 71 (French).

These statutory deadlines are a floor. Internal rules may require immediate notification of the line manager, which is the only realistic way to meet 48 hours in a multi-site company.

4. Mistake 1: not reporting when in doubt

This is the central mistake, and it always takes the same form: "we don't know whether it's a workplace or a commuting accident, so we'll wait until it's clear".

But the employer does not have to characterise anything. It reports the facts as they were relayed, with any reservations, and lets the investigation take its course. Reporting is not admitting: it is opening the file.

5. Mistake 2: waiting for a document

Waiting for the medical certificate, the site manager's report, or the employee's return before reporting leads mechanically to missing the deadline.

The report is made with the information available; supporting documents follow. A file initially incomplete but filed on time is always worth more than a complete file filed late.

6. Mistake 3: not recording the facts

The file is built in the hours following the accident, not weeks later. To record immediately:

  • the date, time and exact place of the accident;
  • the activity underway at the time;
  • a description of the circumstances, as reported by the victim;
  • the identity of witnesses and their written statements;
  • the first aid given and the medical route taken;
  • who in the company was informed, and at what time.

These elements serve twice: to complete the report correctly, and to answer the investigation's later questions without reconstructing events from memory.

7. Mistake 4: treating it as an ordinary absence

Sick leave following a workplace accident is not ordinary sick leave. Unavailability resulting from an occupational accident or disease suspends the employment contract, and benefits fall under the social security scheme: medical costs, hospitalisation, prosthetic appliances, transport, and daily allowances in case of temporary incapacity.

Treating the absence as non-occupational illness leads to an incorrect payroll calculation and a missing report. Labour Code, Article L.34 (French); Social Security Code, Article 85 (French).

8. What to do within the hour

PriorityAction
1Give first aid and get the victim medical care
2Secure the area and prevent a second accident
3Inform the designated manager and HR
4Record the facts and take witness statements while they are fresh
5Prepare and file the report, without waiting for missing documents
6Analyse the cause and correct what made the accident possible

The sixth line is the only one that prevents the next accident. The first five deal with the event; that one deals with the cause.
