Asbestos Medical Surveillance

Asbestos causes asbestosis, lung cancer, and mesothelioma; affects workers in construction/demolition, shipyards, insulation, brake/friction work, and abatement.

PEL0.1 fiber/cc (8-hr TWA); excursion limit 1.0 fiber/cc averaged over 30 minutes

General Industry

Who is covered: All employees exposed at or above the TWA and/or excursion limit [1910.1001(l)(1)(i)]

Evaluation performed by: Licensed physician (employer-selected)

🩺 Baseline / Pre-Placement

Pre-placement, before assignment to an asbestos-exposed occupation

  • Medical and work history
  • A standardized questionnaire about breathing symptoms, smoking history, and past job exposures (Part 1) (regulatory term: respiratory disease standardized questionnaire)
  • Complete physical examination of all systems — emphasis on the respiratory system, cardiovascular system, and digestive tract
  • Chest X-ray (posterior-anterior; 14×17-inch or other reasonably-sized standard film or digital) (regulatory term: chest roentgenogram, 29 CFR 1910.1001 Appendix E)
  • Pulmonary function tests — forced vital capacity (FVC) and forced expiratory volume in one second (FEV1)
  • Any additional tests deemed appropriate by the examining physician

A standardized respiratory-symptom questionnaire (initial and periodic versions) covering shortness of breath, cough, phlegm, wheeze, chest illness, smoking history, and occupational exposure history. The physician administers it to detect early respiratory impairment.

Appendix E — How the chest X-ray is read (B-reader / ILO) 29 CFR 1910.1001 / 1926.1101 / 1915.1001 App. E; 8 CCR 5208 / 1529 / 8358 App. E

The chest film is read by a physician certified by NIOSH as a "B-reader" and graded on the ILO International Classification 0-3 scale for small opacities and pleural changes. This standardized reading is what distinguishes the required film from an ordinary chest X-ray. Standard film or digital images are acceptable.

🕒 Periodic / Routine

Interval-based while covered (covered-status triggered) — NOT result-triggered

Schedule: Made available annually [1910.1001(l)(3)(i)]; chest X-ray at the frequency set by Table 1 (age × years since first exposure) — table shown in this section.

How this compares to Cal/OSHA: General industry standards are substantively aligned — same 0.1 f/cc PEL and 1.0 f/cc excursion limit, the same Appendix D respiratory questionnaire (Part 1 initial / Part 2 periodic), ILO-classified chest X-ray (Appendix E; standard film or digital), periodic examinations made available annually, and a termination exam within 30 calendar days of termination. They differ on chest X-ray frequency: federal Table 1 (1910.1001 only) reaches annual films only at age 45+ with 10+ years since first exposure (every other combination is every 5 years, except every 2 years at age 35+–45 with 10+ years), while California Table 2 requires annual films for every combination except employees under 40 with under 10 years since first exposure (every 3 years), and — California only — oblique x-rays need only be performed every 3 years. Outside general industry the gap widens: the federal construction (1926.1101) and shipyard (1915.1001) standards leave the chest X-ray to the physician's discretion, contain no X-ray frequency table, and require no termination examination, whereas all three California sections — 8 CCR 5208 (general industry), 1529 (construction), and 8358 (ship repairing, shipbuilding, and shipbreaking) — administer the X-ray in accordance with Table 2 and require a termination examination (examination content is prescribed only in 5208). Construction/shipyard coverage triggers match across jurisdictions: a combined total of 30+ days per year of Class I/II/III work or exposure at/above the PEL, plus a physician-supervised physical-ability determination for employees otherwise required to wear a negative-pressure respirator.
