Ever heard someone say, “This product is OEB 4” and Wondered what that really means?
OEB stands for Occupational Exposure Band—a classification system that helps determine how potent a pharmaceutical compound is.
OEL stands for Occupational Exposure Limit—The maximum amount of that pharmaceutical compound; workers can safely be exposed to during work. It’s based on scientific studies and helps protect health. (Usually expressed as µg/m³ of air in 8-hour shift)
Here’s a quick breakdown:
- OEB 1 = OEL would be 1000 to 5000 µg/m³
- OEB 2 = OEL would be 100 to 1000 µg/m
- OEB 3 = OEL would be 10 to 100 µg/m³
- OEB 4 = OEL would be 1 to 10 µg/m³
- OEB 5 = OEL would be 0.1 to 1 µg/m³
- OEB 6 = OEL would be less than 0.1 µg/m³
The higher the OEB, the tighter the containment.
For Example:
- OEB 1–2 : Low-risk materials—PPE, Extraction systems and good practices may suffice
- OEB 3–4 : Moderate to high potency—requires engineered containment like isolators or RABS.
- OEB 5–6 : Extremely potent—strict controls, full isolator systems, and validated cleaning protocols are a must.
