A. No. The IDL is a list of substances which, if present in a WHMIS controlled product, must be disclosed on the MSDS if present at or above the specified “cut-off” concentration; (either 1.0% or 0.1%). Ingredient disclosure is not limited to substances which appear on the IDL. Substances included on the IDL are one of several categories of ingredients which must be disclosed on the MSDS if present in a controlled product. The criteria for ingredient disclosure is set out in subparagraphs 13(a)(i) to (iv) of the HPA.
