 General terms and guidelines

1- The occupational disease listed in this schedule is the disease where the
contributor contracted as a result of exposure to substances and dangerous
conditions in processes, trades or occupations taking into account the
specific conditions set forth therein.

2- Two criteria were used to determine diseases for inclusion in the

schedule.

i. Strong causal relationship between the disease and occupational

exposure.

ii. The disease occurs among a group of exposed persons with a

frequency above the average morbidity of the rest of the population.

3- The main purpose of developing this schedule is for compensation of

approved occupational disease cases according to GOSI law.

4- The schedule is expected to help in attaining the following objectives:

i. Raise awareness to the importance of prevention and that measures

can be taken to reduce the incidence of occupational diseases.

ii. Assist in uniformity and reliability of identifying, recognizing, and

registering occupational diseases at a national level.

5- It should be considered that quitting work for any reason, or working

in other jobs in the same or other establishments, should not deprive
the worker from the right to evaluate and approve his condition or
illness as an occupational disease when special conditions of the
disease are met, provided that the disease appears within the maximum
periods set forth in this schedule or based on the most recent scientific
evidence. When there is no reference regarding the maximum period
for the disease to appear, the medical committee should decide that.

6- When evaluating occupational diseases, the medical committees

should base their decisions solely on medical and occupational history,
clinical symptoms, pre-placement and periodic examination, medical
reports, laboratory tests, in addition to occupational hygiene assessment
of the work environment, which should be based on the internationally
recognizable permissible limits.
