Pleural Plaques, Smoking, and an Expired Respirator Clearance
During a routine site visit at a manufacturing plant, a 47-year-old maintenance mechanic tells the safety manager that he has smoked one pack per day for 25 years and has increasing shortness of breath. He has worked in the plant for 14 years, regularly repairing steam traps and pipe insulation that the plant assumes contains asbestos. His last chest X-ray was three years ago and showed pleural plaques; the report was placed in his personnel file. He has never had a pulmonary function test at work. The employer provides a half-mask P100 respirator and fit-tests him annually, but the last medical clearance was four years ago. He is scheduled for a 30-day shutdown job removing valve insulation. He says he feels fine and does not want to see a doctor because he fears losing his job. The plant has no written medical surveillance program.
1. Is the mechanic entitled to medical surveillance, and what should the examination include and when should it occur?
Read the worked answer
He is entitled to medical surveillance. Under OSHA 29 CFR 1926.1101(m), medical examinations must be provided at no cost to employees who are exposed at or above the permissible exposure limit or who engage in Class I, II, or III asbestos work for 30 or more days per year. The scheduled 30-day valve insulation removal is Class I thermal system insulation work, so he meets the trigger even before considering his 14 years of maintenance exposure. The examination should be performed before assignment and annually thereafter, and it should include a medical and work history, physical examination, chest X-ray, pulmonary function test, and any additional tests the physician orders. The prior X-ray is three years old and is not a substitute for the current surveillance examination. His four-year-old respirator clearance is also insufficient because the standard requires annual medical evaluation for respirator use and the physician must determine fitness before the shutdown job. The employer cannot rely on the employee's statement that he feels fine, and the employee cannot waive the examination if the exposure triggers apply.
2. How should the safety manager respond to the pleural plaques, the smoking history, and the worker's fear of job loss?
Read the worked answer
The manager should not diagnose or interpret the plaques personally. The findings should be sent to the examining physician, who should receive the prior X-ray report, exposure history, smoking history, and job description. Pleural plaques are evidence of past asbestos exposure but do not by themselves establish current disability or cancer; the physician must determine whether further evaluation or work restrictions are needed. The manager should explain that the examination is confidential and is not a disciplinary action, and that the employer cannot retaliate against him for participating. Because smoking and asbestos act synergistically, the physician should discuss smoking cessation, but the employer should not make employment contingent on quitting. The respirator fit test should not proceed until the physician clears him for respirator use, and the fit test must be repeated annually. Records of the examination must be kept confidential and retained for 30 years. If the physician recommends restrictions, the employer should evaluate whether the shutdown task can be modified or reassigned rather than simply removing him from work.
