The employer shall institute a medical surveillance program for all employees who,for a combined total of 30 or more days per year, are engaged in Class I, II, and III workor are exposed at or above the permissible exposure limit. For purposes of thisparagraph, any day in which a worker engages in Class II or Class III operations or acombination thereof on intact material for one hour or less (taking into account the entiretime spent on the removal operation, including cleanup) and, while doing so, adheresfully to the work practices specified in this standard, shall not be counted.B.

This determination shall be made under the supervision of aphysician.When are asbestos medical surveillance physical exams required ?1. Prior to assignment ofthe employee to an area where negative-pressure respiratorsare worn;2. When the employee is assigned to an area where exposure to asbestos may be at orabove the permissible exposure limit for 30 or more days per year, or engage in Class I,II or III work for a combined total of 30 or more days per year, a medical examinationmust be given within 10 working days following the thirtieth day of exposure;3. And at least annually thereafter.4. If the examining physician determines that any of the examinations should beprovided more frequently than specified, the employer shall provide such examinationsto affected employees at the frequencies specified by the physician.5.
