Types of occupational accidents covered

The statistics covered reported occupational injuries due to all types of occupational accidents.

Statistics of occupational diseases are compiled separately. However, certain illnesses are recognized as equivalent to an occupational injury, for example, illness caused by solvents, asbestos or other minute particles, poisoning or other effects from chemicals, and allergic skin and lung diseases, and are covered as such in the statistics.

Commuting accidents are not included. Accidents occurring while employees are travelling by car or some other means of transport as required by the nature of their work are covered.

Method of data collection


National Insurance Act.

All occupational injuries should be reported within three days of the date of the accident to the local National Insurance Office.


The employer should report the injury or illness using a standard form comprising five copies. Copies 1, 2 and 3 are sent to the local National Insurance Office, which forwards copy 3 to the Directorate of Labour Inspection. The employer retains copy 4 and gives copy 5 to the injured person. Separate forms are used for accidents aboard ship or on fishing vessels. Instructions for completion are included on the forms.

Data reported:

The form consists of the following:
  1. information about the injured person: date of birth and national identity number, name, address, nationality, date from which employed, present position, duration of employment in present position;
  2. information about the employer: name, address, national employer identification number, economic activity, type of enterprise (description), accident site if the accident did not occur at the address of the employer;
  3. information about earnings: basic wage; sum of regular increments, overtime pay, etc., in present position during the last 12 months, type of employment at the time of the accident (regular, temporary, etc.);
  4. information about the time and place of the accident: date and time; whether the accident happened during daytime; whether the accident happened while working overtime; type of wages (fixed wage, piece rate, etc.); place of accident (regular workplace, on the way to or from work, during normal working hours, etc.); whether the accident was reported to the Labour Inspection (in the case of serious accidents), and whether the injury was fatal;
  5. information about how the accident happened and the nature of the injury: type of work at the moment the accident occurred: maintenance, repairs, assembly work using machines or cranes, etc., cleaning, handling of cargo, internal transport, production work, other;
  6. description of the accident (free text);
  7. signature of the reporting employer.

No changes are planned for the near future.

Additional information

Act No. 4 of February 1977 respecting workers' protection and the working environment, as amended to Act No. 2 of 6 January 1995 also sets out obligations for reporting occupational injuries. Employers should ensure that all injuries occurring during performance of work are registered. The register should be accessible to the Inspectorate of Labour, safety delegates, the working environment committee and the safety and health personnel. If, as a result of an occupational accident, an employee loses his life or is seriously injured, the employer should immediately, and by the quickest possible means, notify the Inspectorate of Labour and the nearest police authority. The employer should confirm its notification in writing, and the safety delegate should receive a copy of the confirmation. The Directorate of Labour may also require such notification to be given in other cases, such as acute poisonings and near accidents. Any medical practitioner who through his work gains knowledge of an employee suffering from an occupational injury should report this in writing to the Inspectorate of Labour.
