13 Carcinogens Medical Surveillance

A group of 13 no-PEL carcinogens (e.g., benzidine, beta-naphthylamine, bis-chloromethyl ether) regulated by a regulated-area / no-detectable-contact model; affects research, chemical-manufacturing, and laboratory workers handling these substances.

Who is covered: Employees considered for assignment to enter regulated areas and authorized employees. No air PEL — regulation is by contact/regulated area wherever a covered carcinogen is manufactured, processed, used, repackaged, released, handled, or stored [1910.1003(c), (g)]

Evaluation performed by: Physician (licensed)

🩺 Baseline / Pre-Placement

Before an employee enters (is assigned to) a regulated area [1910.1003(g)(1)(i)]

  • Preassignment physical examination by a physician
  • Personal history of the employee and family and occupational background, including genetic and environmental factors [1910.1003(g)(1)(i)]
  • Physician consideration of conditions of increased risk — reduced immunological competence, treatment with steroids or cytotoxic agents, pregnancy, and cigarette smoking [1910.1003(g)(1)(iii)]
  • NOTE: the standard imposes NO substance-specific laboratory panel; specific tests are left to the physician's judgment
🕒 Periodic / Routine

Interval-based while authorized — NOT result-triggered

Schedule: Periodic physical examinations not less often than annually following the preassignment examination [1910.1003(g)(1)(ii)].

  • Physical examination by a physician
  • Updated personal/family/occupational history including genetic and environmental factors
  • Physician consideration of increased-risk conditions (reduced immunological competence, steroid/cytotoxic treatment, pregnancy, cigarette smoking)
  • NOTE: NO substance-specific laboratory panel is mandated
⚠ Emergency / Post-Exposure

Employee present in the potentially affected area at the time of an emergency [1910.1003(d)(2)(iii)]

  • Special medical surveillance by a physician instituted within 24 hours of the emergency
  • Examination and history as the physician determines (no enumerated lab panel)

Reporting Requirements

Who performs the evaluationPhysician
Reported to employerThe examining physician furnishes the employer a statement of the employee's suitability for employment in the specific exposure [1910.1003(g)(2)(iii)]. The standard does not prescribe a detailed limited written-opinion content list as the substance-specific standards do.
Reported to / for the employeeStandard does not specify a separate employee-notification timetable beyond access to records under 29 CFR 1910.1020.
Time limitsNo specific day-count for furnishing the suitability statement is stated in (g)(2)(iii).
Second-opinion / multi-physician reviewNo multiple-physician review mechanism specified.
RecordkeepingComplete and accurate records of medical examinations maintained for the duration of the employee's employment [1910.1003(g)(2)(i)].

Medical Removal Protection

No medical removal protection program. The standard relies on the physician's suitability statement and increased-risk-factor evaluation rather than result-triggered removal.

How this compares to Cal/OSHA: Substantively aligned — Cal/OSHA 5209 is a close analog of federal 1910.1003: same 13 substances, same preassignment + at-least-annual physical examination, the same genetic/family-history and increased-risk-factor framework, and the same 24-hour emergency surveillance. Critically, NEITHER standard mandates a substance-specific laboratory panel — exam content is physician-determined. (CA recordkeeping detail marked unverified — retention duration not separately confirmed in 5209 text.)
