Massachusetts Flame Retardants and Window Shades

Re: 310 CMR 78.00: Ban of Covered Products Containing Certain Flame Retardants. This law took effect as of April 01, 2021, and is enforced by Mass DEP. 

Quick Summary: Law bans 11 types of chemical flame retardants from "covered products" including window treatments (curtains, blinds, or shades). Products must meet NFPA 701, per MA Codes.

Chemical lobby and window treatment manufacturers association are pushing back against the law. During stakeholder meetings to pass the law, no specific objections were raised. I'm drafting some written testimony in favor, due October 25, to the DEP.

  • Between Draper and MechoSystems, there are nine compliant solar shade cloths already on the market.
  • Many curtains and drapery fabrics are already compliant, mostly thanks to the Healthy Hospitals Initiative.

I've discovered one glaring problem, blackout shades. Today these are made with some type of plastic foam, which cannot pass NFPA 701 without chemical flame retardants. Rachel Berman Berkin (formerly Mecho) has been super helpful explaining this to me.

Should we recommend an exemption for a short period of time (1 more year?) so the industry can develop a new product? Should it be limited to certain uses?

Where do we typically use blackout shades?

  • Schools, for exterior windows where room darkening is desired.
  • Schools, for interior glazed windows, glazed doors, and sidelites, for security.
  • Hospital inpatient rooms, for exterior windows where room darkening is desired.
  • Renovations and retrofits, where rooms are repurposed.

Other uses, like office spaces and multifamily housing, commonly use aluminum blinds and draperies.

Let me know what you think about this issue and if you can put me in touch with a window treatment manufacturer's representative or someone else who you think might be helpful.

Thanks Lisa - was just talking about this yesterday w/ another sustainability leader. Seems like offering a short exemption period is reasonable so industry can adapt/develop something better. In the Lab/office/multi family amenity spaces we work on - we are using roller shades - Mecho type systems, and only blackout shades in the special areas like conf rooms with special purpose such as media editing/presentations.

Our Mermet USA contact, who is also listed on their HPD, provided the attached letter. Anecdotally he shared they've been working on an antimony trioxide-free solution for over a year already (hooray for market signals working!), and should have at least one line ready for 2023 (although it's their PVC coated fiberglass - ugh). FWIW their Sparta Twilight blackout line lists antimony trioxide as ~4% of the content (although another 10-15% of a benzene based HFR not on the MA restricted list). Maybe a short exemption and maximum percent content? Ideally it's zero but perhaps there's an easy step to start reducing quantity but still pass NFPA.

Kristen and Jay, Thank you both. And I think I have found blackout shades from Draper, but still confirming that. Kristen, Yes, we've heard from at least five project teams this week. More of my 'big tech' clients are doing a combination of solar control shades and acoustic/blackout draperies for those special purpose spaces. Jay, I'm concerned shade cloth manufacturers are trying to get around the legislation by adding more chemicals instead of innovating on fabric and fibers. This law includes the opportunity to update the banned chemical list every five years, by scientists from UMass Lowell Toxics Use Reduction Institute (TURI). This has been a really interesting example of how code changes can happen, without changing the building code itself. Who would look to Department of Environmental Protection regulations for something that affects interior window shades? How does this information get to building inspectors? Who's paying attention? Does your Code Consultant know? This law took effect as of April 01, 2021, and we're just having implementation meetings now? -

Does anyone know what labels that already exist include all of the chemical flame retardents listed in MA 310 CMR 78? Lisa mention HHI. How about Red List Free, California Prop 65, others?
