CHemical RISk calculators (CHRIS) - Bulk chemicals RST

Note: This module only addresses risk associated with the bulk chemicals, excluding color additives, of known initial quantity. For color additives, please use the color additive module.

For details on how to use the CHRIS bulk chemical module, please click the information icons next to each section header and read the context of use (COU), which includes limitations of use.

Check all statements below that are applicable to the component being evaluated:

The clinical use environment does not cause the polymer matrix to swell or degrade.
Any particles/aggregates of the chemical present in the polymer are much smaller than the smallest component dimension (≤ 50x).
The chemical is homogeneously distributed throughout the polymer.
The total amount of the chemical is present in dilute concentrations (≤ 2 m/v %).
Manufacturing processes do not impact the stability of the polymer.
