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: Covers the same 13 carcinogens under the same regulated-area model; program for employees considered for assignment to, and authorized to enter, regulated areas [5209(g)]

Evaluation performed by: Licensed physician

🩺 Baseline / Pre-Placement

Before an employee enters a regulated area [5209(g)(1)(A)]

  • Preassignment medical examination by a licensed physician
  • Personal and family history with respect to genetic and occupational factors [5209(g)(1)(A)]
  • Physician consideration of conditions of increased risk — reduced immunological competence, steroid/cytotoxic treatment, pregnancy, cigarette smoking [5209(g)(1)(C)]
  • NOTE: no substance-specific laboratory panel mandated
🕒 Periodic / Routine

Interval-based while authorized — NOT result-triggered

Schedule: Periodic examinations not less often than annually [5209(g)(1)(B)].

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

Employee present at the time of an emergency [5209(d)]

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

Reporting Requirements

Who performs the evaluationLicensed physician
Reported to employerPhysician furnishes a statement of the employee's suitability for the specific exposure; no detailed limited-written-opinion content list as in substance-specific standards.
Reported to / for the employeeNo separate employee-notification timetable specified beyond records access under 8 CCR 3204.
Second-opinion / multi-physician reviewNo multiple-physician review mechanism specified.
RecordkeepingRecords maintained for the duration of the employee's employment; upon termination, retirement, or death, records (or notarized copies) are forwarded by registered mail to the Director, NIOSH [5209(g)(2)(A)].

Medical Removal Protection

No medical removal protection program — relies on physician suitability evaluation and increased-risk-factor consideration.

How this compares to Federal 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.)
