“…Industry cleaning strategies under good manufacturing practice (GMP) usually apply strict procedures, where potential cross‐contamination is eliminated. For example, concentration‐dependent local effects in the next product play a minor role for adverse reactions and risk to the patient, if the substance reacts in the process (Araya et al, 2022). Generally, internal quality criteria and GMP‐related processes should be followed where extrapolated PDEs exceed the general quality attributes.…”

Contract Development and Manufacturing Organizations (CDMOs) that manufacture large, diverse portfolio of chemical and pharmaceutical substances require pragmatic risk-based decisions with respect to the safe carry-over between different chemical entities, as well as for worker protection. Additionally, CDMOs may not have access to primary study data, or data are generally lacking for a specific substance. While pharmaceuticals require the establishment of health-based exposure limits (HBELs) (e.g., occupational exposure limits [OELs] and permitted daily exposure [PDE] limits), the limits for nonhazardous substances could be set in a protective and pragmatic way by using default values, when internally required. Because there is no aligned definition provided by authorities, nor agreed default values for nonhazardous substances, we provide a decision tree in order to help qualified experts (such as qualified toxicologists) to identify the group of nonhazardous substances and to assign default HBEL values for specific routes of exposure. The nonhazardous substances discussed within this publication are part of the following subgroups: (I) inactive pharmaceutical ingredients, (II) pharmaceutical excipients or cosmetic ingredients, (III) substances Generally Recognized as Safe (GRAS), and (IV) food ingredients, additives, and contact materials. The proposed default limit values are 1 mg/m 3 for the OEL and 50 mg/day for the PDE oral and intravenous (IV) route.
