CPSC Near to Publishing Updated Methylene Chloride Guide
Commissioners were slated to vote as PSL went to press on publishing an updated guidance on labeling paint stripper products containing methylene chloride (dichloromethane or DCM). It would be effective upon appearing in the Federal Register.
Commissioners voted 5-0 last year (PSL, 6/12/17) to grant a 2016 petition that sought an update to better address acute inhalation risks associated with use in enclosed spaces like bathtubs, sinks, or closets. The existing guidance came out in 1987.
The briefing package (bit.ly/2FCwRbQ) includes assessments by various CPSC offices:
When urging commissioners to grant the petition last year (PSL, 6/5/17), staffers rejected calls for delayed action despite related work at EPA as well as efforts in California and by the ASTM D01.42 subcommittee. Similar to the regulatory assessment above, staffers saw the update – at least with EPA – as being complementary not conflicting.
Meanwhile, since then, California's DTSC sought input on declaring strippers with DCM to be priority products (PSL, 11/27/17).
