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 engineered into every action, not bolted on.
Because V5 owns the operator action, the QMS sees the data the second it’s captured — not at the end of the shift.
Document control with hard kiosk-level training enforcement.
Versioned SOPs are only useful if operators are actually trained on the current version. V5 enforces it at the kiosk.
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/PQ scripts, traceability matrix, risk assessment, intended-use statement — generates from the same evidence so you can hand it to an auditor on day one.
