Federal vs. California: California's 2025 revision slashed the AL to 2 µg/m³ and PEL to 10 µg/m³ (vs federal 30/50) and lowered the MRP removal/return thresholds dramatically (removal at BLL ≥30 vs federal 50–60) — far more protective than federal. California also adds tiered accelerated-monitoring triggers (10–19, ≥20) and a written elevated-BLL response plan.

Construction
No separate Cal/OSHA construction inorganic-arsenic standard exists; California regulates inorganic arsenic for general industry under 8 CCR 5214. Construction work in California involving inorganic arsenic is addressed through general Title 8 toxic-substance and exposure-control provisions rather than a dedicated arsenic construction section.
Federal vs. California: Materially different on periodic surveillance and required tests. Federal (1910.1018 / 1926.1118) sets a single periodic frequency of 'at least annually' with NO age/tenure split and mandates only history, posterior-anterior chest X-ray, and nasal/skin exam — sputum cytology, CBC, and lymph-node exams are NOT required by the federal regulatory text. California 8 CCR 5214 imposes a two-tier periodic frequency (annual for age <45 AND <10 years; semi-annual for age ≥45 OR ≥10 years), a broader physical exam (skin, nose, respiratory tract, lymph nodes, nervous system, liver), and a mandatory sputum cytology examination at the initial exam and at each semi-annual (high-risk) exam. AL (5 µg/m³) and PEL (10 µg/m³) are identical; neither jurisdiction has automatic medical removal protection. California has no separate construction arsenic section.
Beryllium
Beryllium causes chronic beryllium disease (CBD), beryllium sensitization, and lung cancer; affects workers in machining, foundry/smelting, ceramics, dental labs, and aerospace/defense manufacturing.

Federal vs. California: 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.

Federal vs. California: Essentially aligned — California adopted the federal BD standard nearly verbatim (identical AL/PEL/STEL, annual CBC + questionnaire, triennial physical, 48-hour emergency CBC + monthly-for-3-months protocol). The meaningful jurisdictional note is structural: federal has NO construction variant (1926.1151 does not exist), so the requirement lives only in general industry; California likewise has a single general-industry section (5201).

4,4'-Methylenebis(2-Chloroaniline) (MBOCA/MOCA)
Other Organics & CarcinogensMBOCA (MOCA) is a probable bladder/liver carcinogen absorbed through skin; affects workers in polyurethane elastomer/casting and curing-agent operations. Surveillance keys on a urinary biological exposure limit rather than airborne sampling.
Federal OSHA osha.gov
General Industry
No direct federal OSHA substance-specific MBOCA standard exists. (MBOCA was among substances OSHA addressed by separate rulemaking that did not survive as a discrete substance standard.) Federal coverage is general only — Hazard Communication (1910.1200) and the General Duty Clause. Documented here primarily to prevent citation confusion: Cal/OSHA regulates MBOCA at 8 CCR 5215, which is distinct from DBCP at 8 CCR 5212.
Cal/OSHA dir.ca.gov
All Covered Work
| Action Level | Use-based trigger (no airborne AL/PEL framework). Biological exposure limit: urine MBOCA ≤ 100 µg per liter of urine, specific gravity adjusted to 1.024 [5215(c)(1)] |

Construction
Construction noise standards (29 CFR 1926.52 permissible exposure and 29 CFR 1926.101 hearing protection) require feasible controls and provision/fitting/use of hearing protectors (plain cotton not acceptable) when exposures exceed Table D-2 (90 dBA/8 hr). They reference a 'continuing, effective hearing conservation program' in the abstract but PRESCRIBE NO audiometric monitoring program — no baseline/annual audiograms, no STS provisions, and no PLHCP medical evaluation. From a medical-surveillance standpoint there is NO mandated audiometric exam requirement in construction.

Construction
California construction noise is governed by Cal/OSHA construction safety orders; the audiometric/hearing-conservation medical provisions are set out in the general-industry noise sections (8 CCR 5095-5100, audiometric content in 5097) applied to covered employees at/above the 85 dBA Action Level. A construction-specific audiometric carve-out is NOT separately detailed here; confirm the precise construction cross-reference against the enrolled construction safety orders before relying on it for a construction-only employer.
Federal vs. California: Essentially aligned for the medical/audiometric requirements — 8 CCR 5097 tracks 29 CFR 1910.95 (same 85 dBA Action Level, same baseline-within-6-months and annual-audiogram timing, same STS definition of avg ≥10 dB at 2000/3000/4000 Hz). Key structural differences: California splits the noise rule across 5095-5100 (audiometric content in 5097) whereas federal packs it into a single 1910.95; and federal CONSTRUCTION (1926.52/1926.101) mandates only hearing protectors with NO audiometric program — the largest sector gap.

There is no federal baseline/annual TB testing or post-exposure ATD evaluation mandate. (California analog: 8 CCR 5199.)

All Covered Work
| Covered | Health care facilities (hospitals, skilled nursing, clinics, outpatient medical offices, home health, hospice, paramedic/EMS); high-risk facilities (correctional facilities, homeless shelters, drug-treatment programs); public-health operations (contact tracing, screening); police during transport/detention of suspected ATD cases; laboratories handling aerosol-transmissible pathogens; cadaver-handling operations (pathology labs, medical examiners, coroners, mortuaries); and contaminated air-handling maintenance. Limited exceptions for certain outpatient dental/specialty practices with screening — 8 CCR 5199(a). |
|---|---|
| Physician Type | PLHCP knowledgeable in occupational TB/ATD evaluation (TB management referrals to a PLHCP knowledgeable in TB diagnosis/treatment) |
| Removal (MRP) | No MRP. Program is baseline + annual TB surveillance plus event-triggered TB-conversion evaluation and post-exposure response (see abnormal_protocols). Medical records may be combined with the 5193 (bloodborne) medical record — 8 CCR 5199(j)(1)(A) — though the two standards cover non-overlapping disease routes (airborne vs. bloodborne). |
🩺 Baseline / Pre-Placement
On hire/assignment into an ATD exposure-risk classification — 8 CCR 5199(h)
- Baseline TB screening/testing for new hires in exposure-risk job classifications (TB skin test or IGRA blood test, per the facility's program) — 8 CCR 5199(h)
- Vaccines listed in Appendix E (e.g., for susceptible exposed workers) made available at no cost within 10 working days of assignment — 8 CCR 5199(h)(5)
- Medical-history/screening as part of program enrollment
🕒 Periodic / Routine
Interval-based for exposed employees — NOT result-triggered
Schedule: Annual TB testing/assessment for all exposed employees — 8 CCR 5199(h)(3)
- Annual TB testing/assessment (symptom screen and/or TB test per program and risk level) for exposed employees — 8 CCR 5199(h)(3)
Abnormal Results & Exposure-Event Protocols
- Employee TB test conversion (new positive) 8 CCR 5199(h)(3): Provide a medical evaluation and refer the employee to a PLHCP knowledgeable in the diagnosis/treatment of TB for further evaluation and management. Tests: Medical evaluation of the TB conversion, Referral to a PLHCP knowledgeable in TB diagnosis and treatment, Symptom assessment and chest imaging as clinically indicated by the PLHCP
- Significant exposure incident / suspected or confirmed ATD case exposure 8 CCR 5199(h)(6): Conduct an exposure analysis within 72 hours; provide a post-exposure MEDICAL EVALUATION within 96 hours of the exposure; report suspected reportable ATD cases to the local health officer; notify other potentially exposed employers within 72 hours. Tests: Exposure incident analysis within 72 hours, Post-exposure medical evaluation within 96 hours, Reporting of suspected case to the local health officer, Notification of other potentially exposed employers within 72 hours, Post-exposure prophylaxis/treatment as recommended by the PLHCP
Reporting Requirements
| Who performs the evaluation | PLHCP (referrals for TB conversion to a PLHCP knowledgeable in TB diagnosis/treatment) — 8 CCR 5199(h). |
|---|---|
| Reported to employer | Employer receives the PLHCP's written opinion/recommendation on work status and any work restrictions related to ATD exposure; clinical details remain confidential. |
| Reported to / for the employee | Employee informed of TB test results, conversion status, exposure-incident findings, and any need for further evaluation/treatment; copy of the written opinion provided. |
| Time limits | Exposure analysis within 72 hours; post-exposure medical evaluation within 96 hours; suspected-case report to the local health officer; notification of other potentially exposed employers within 72 hours — 8 CCR 5199(h)(6). |
| Recordkeeping | Confidential ATD medical records retained per 8 CCR 3204 (duration of employment plus 30 years); may be combined with the 5193 medical record — 8 CCR 5199(j)(1)(A). |
Federal vs. California: California-only standard. 8 CCR 5199 mandates baseline and ANNUAL TB testing/assessment, TB-conversion medical evaluation/referral, Appendix E vaccination offers, and a structured post-exposure pathway (72-hour exposure analysis, 96-hour post-exposure medical evaluation, local-health-officer reporting). There is NO federal OSHA equivalent — federal airborne-pathogen risk is covered only indirectly via 1910.134 and the General Duty Clause.
