Dermatitis Check All employees who are exposed to substances that are hazardous to their health must have a dermatitis check to comply with the health surveillance monitoring outlined in the COSHH (Regulation 11). A full list of the substances that may cause occupational dermatitis can be supplied on request. The list will include epoxy resins, solvents, paints and engine oil. The employee will be requested to complete a questionnaire before his/her hands are checked to establish whether dermatitis is present. If dermatitis is suspected or detected will issue a letter for the employee to give to his/her family doctor. Information and instruction is given in good skin care practices, and the necessary steps to take if skin problems occur. The dermatitis check should be carried out annually.
