[Patch tests performed with Epidian in workers exposed to epoxy resins]

The patch tests according to the Jadassohn-Bloch's method were made with five Polish epoxy resins--"Epidian"--in 487 workers exposed to their action, and in 113 persons of the control group. The percentage of sensitized persons among 487 examined amounted to 22,8%, the results of test in the control group being negative. It has been found that particularly sensitizing action is produced by the non hardened resins (the percentage of persons sensitized in the group working at non hardened resins was 26,7, at hardening ones--2.6).
