Coke Oven Emissions Medical Surveillance

Coke oven emissions (PAH-rich particulate) cause lung and kidney cancer; affects workers on coke oven batteries in steel production within regulated areas.

PEL0.15 mg/m³ (= 150 µg/m³) averaged over any 8-hour period [5211(c)]
Who is covered: Each employee employed in a regulated area at least 30 days/year [5211(s)(1)(A)]

Evaluation performed by: Licensed physician (employer-selected)

🚪 Exit / Termination

At termination of employment, if no qualifying exam was performed in the prior 6 months [5211(s)(3)(D)]

  • Work and medical history including smoking history and respiratory symptoms
  • PA chest X-ray with ILO U/C (UICC/Cincinnati) classification rating [5211(s)(2)(B)]

Reporting Requirements

Who performs the evaluationLicensed physician (employer-selected)
Reported to employerWritten opinion limited to: results of the examination; any detected condition placing the employee at increased risk from coke-oven emissions; recommended exposure limitations; and a statement that the employee was informed of the results and any condition needing further evaluation. Unrelated findings must not be revealed [5211(s)(5)(A)].
Reported to / for the employeeEmployer provides a copy of the written opinion to the employee; employee informed of results and of any condition needing further evaluation.
Time limitsThe standard does not specify an explicit deadline for furnishing the copy to the employee (see unverified note).
Second-opinion / multi-physician reviewNo formal multiple-physician review mechanism specified.
RecordkeepingMedical records retained per 8 CCR 3204 (duration of employment plus 30 years).

Medical Removal Protection

No medical removal protection scheme; physician's written opinion conveys results, risk assessment, and exposure limitations.

How this compares to Federal OSHA: Largest divergence of the four substances. California 8 CCR 5211 is materially more stringent than federal 1910.1029 in three ways: (1) it requires SPUTUM cytology (5211(s)(2)(G)), which federal 1910.1029 does not require at all (federal requires URINARY cytology only); (2) it mandates SEMI-ANNUAL (every-6-month) exams for the 45+/5-year group (5211(s)(3)(B)), whereas federal is ANNUAL for that group (federal adds urinary cytology annually, not on a 6-month interval); and (3) it mandates ILO U/C classification of the chest X-ray (5211(s)(2)(B)), whereas federal 1910.1029 requires the X-ray but not ILO classification. Both jurisdictions agree on the 150 µg/m³ PEL, the 30-days/year regulated-area trigger, and urinary cytology.
