Health-Based Exposure Limits (HBEL), expressed as Permitted Daily Exposure (PDE) in µg/day, are the toxicologist-derived cross-contamination limits that the EMA Q&A and ISPE Risk-MaPP framework require for any shared-equipment supplement plant where the carryover product could expose the consumer. The PDE is derived from NOAEL/LOAEL with safety factors and replaces the legacy 1/1000th and 10-ppm calculations for highly potent or sensitising materials.

How V5 handles it

QMS — quality records next to the work they concern.

Deviations, corrective actions and quality review sit in the same system as production, so each quality record references the work order, step and lot it concerns.

Document control — one version in force, every change signed and explained.

Draft the next revision while the current one stays in use, approve it under your sign-off route, and track training on it — with the history kept.

Score your compliance gap — then download the validation pack.

A guided self-assessment walks you against the regulator clauses that apply to your industry. The validation pack — IQ/OQ scripts, traceability matrix, risk assessment, intended-use statement — generates from the same evidence so you can hand it to an auditor on day one.
