An evergreen source briefing on the distinction between the safety basis and routine cleaning limits.
What happened?
EMA’s 2018 Q&A distinguishes health-based exposure assessments from operational cleaning limits. This is background guidance, not a new regulatory development.
EDITORIAL INTERPRETATION
Why does it matter?
A calculation and an operating decision need different supporting explanations.
Key points
- Identify what each limit represents.
- Keep source assessment and operating rationale traceable.
- Define the response to an excursion.
Practical impact
Discussion prompt: add a short “purpose of this value” field to the limit worksheet so reviewers can distinguish safety assessment, acceptance and monitoring decisions.
