Medical Surveillance

    Malaysia is taking great steps to be an industrialized nation by the year 2020. This will entail heavy and extensive use of chemicals. The purpose of medical surveillance is for the early identification of conditions, if any, that could present an increased risk of adverse health effects related to the task being performed.


                Based on the type of work being performed, including consideration of factors such as the duration of the task, the materials being used, and the potential for exposure, medical surveillance is either recommended or required for the job.


                Specific test results and other personal medical information generated by these exams will be kept confidential between the employee and the physician. The physician will determine the scope of the exam, then inform the supervisor of their recommendations based on the exam results. The supervisor will discuss these recommendations, if any, with the employee. The employee can contact the physician who performs the exam with any questions regarding the test results.


                The Occupational Safety and Health (Classification, Packaging and Labeling) Regulations 1997 and the Manual of Chemical Health Risk Assessment 2000 requires employers to assess whether there is any significant exposure of the chemicals to the worker and further medical surveillance is necessary.


                The Occupational Safety and Health (Use and Standards of Exposure of Chemicals Hazardous to Health) Regulations 2000 is another attempt to further enhance the safe and healthy use of chemicals. Under this Regulations health surveillance is based on the Chemical Health Risk Assesment (CHRA) as stipulated in the regulations. Medical surveillance carried out under the USECHH Regulations must be conducted by an Occupational Health Doctor (OHD).
