These tables are classified in three categories:

  • the morbid manifestations of acute or chronic intoxication presented by the employees exposed in a usual way to the action of the harmful agents (for example lead poisoning affection born from the manipulation of the lead: table n ° 1)
  • microbial infections, (tetanus: table n ° 7)
  • conditions resulting from work environments or specific attitudes arising from work (deafness: table n ° 42 or ocular affections …)

These tables establish a presumption of imputability between the malice described in a table and the work likely to cause the disease. In short, the affections listed and defined in the tables are presumed to be of occupational origin. Given this presumption, the employee who wants to obtain compensation will not have to prove the causal link between his affection and his work.

Thus, to be compensated, the occupational disease must be recognized as such, by means of tables establishing on the one hand a limiting list of occupational diseases and on the other hand the conditions of entitlement. benefits for each of these diseases.

The pathology of the employee must therefore meet certain conditions:

  • the disease must be included in one of the tables designating occupational diseases
  • the illness must be recorded within the period of care

A third condition relating to the performance of the work likely to cause the affection may also be necessary.

The conditions listed are presumed to be of occupational origin when it is established that the employee who suffers from them has been habitually exposed, during his professional activity, to the action of harmful agents.

For example, deafness of an employee is presumed to be attributable to work, since the noises to which he has been exposed during his professional activity appear on the list in Table 42 of occupational diseases.

Concerning the delay in taking charge of the illness, according to Article L 461-2 paragraph 5 of the Social Security Code, it is from the date on which the employee ceased to be exposed to the illness. action of the harmful agents in the tables that the diseases can be taken care of under the professional legislation provided that the first medical observation occurs during the time fixed by each table.

The employee must not have ceased to be exposed to the risk for a given period of time during the first medical observation.

It is therefore the cessation of exposure to risk that marks the starting point of the care period.

In addition, if one or more conditions relating to the delay in the period of taking over, the duration of exposure to the risk or the limiting list of the work are not fulfilled, the disease as it is designated in one of the tables occupational disease can be recognized as work-related when it is established that it is directly caused by the victim's usual work.

Indeed, the major drawback of the system was that a disease not listed on one of the tables of occupational diseases could not be supported as such.
