Reporting an accident and recognition of its occupational nature are two different steps. A company must also act on prevention and not wait for an incident before reviewing risks.

When to contact them and what to prepare

In the event of an incident, gather the facts, dates, circumstances and information required for the official form. Keep an objective description and identify prevention measures to review. Coordination with payroll and other social declarations must avoid inconsistencies while limiting the circulation of personal data.
