OEL / OEB
Occupational Exposure Limit / Occupational Exposure Band · oel · oeb · containment band
Toxicology-derived airborne-exposure limit for an API (OEL, µg/m³) and the banded category (OEB 1–5/6) used to specify containment and PPE.
The Occupational Exposure Limit is the airborne concentration a worker can be exposed to over an 8-hour TWA without adverse effect. OELs run from milligrams/m³ (low-potent) down to nanograms/m³ (highly-potent / cytotoxic). OEBs band these into 4–6 categories (1 = open handling acceptable, 5/6 = full isolator + decontamination required).
V5 stores OEL/OEB per API, drives PPE prompts at kiosk dispense, enforces isolator/contained-booth selection in routing, and blocks open weighing of OEB ≥4 materials in non-qualified rooms.
