In particular, the Government of Canada is considering the action, as below, to address health concerns:

(*) for Paint and Coatings Products and Do-It-Yourself (DIY) Products - Regulatory or non-regulatory measures to help reduce consumer exposure to MEKMIBK2,4-PD in paints / coatings products and do-it-yourself (DIY) products;

Moreover, because certain data gaps remain, information on the following items should be provided (on or before March 2019), to the contact details identified in section 8 of this document, to inform risk management decision-making:

(*) Ranges of concentrations of any of MEK, MIBK, and 2,4-PD in paints / coatings products and DIY products, available to consumers in Canada;

(*) Occurrence / content of ventilation statements on paints and coatings products and DIY products containing any of MEK, MIBK and 2,4-PD.

The risk management option outlined in this RM Scope document may evolve through consideration of assessments and RM options published for other Chemicals Management Plan (CMP) substances as required, to ensure effective, coordinated, and consistent risk management decision-making.
