Healthy Materials Guide

FLOORING: •

When possible, specify vinyl-free flooring products including rubber, linoleum, or bio-based products.

• Suggest bio-based alternates to vinyl. If a client insists on vinyl, consider a pthalate-free and PVC-free vinyl and avoid post-consumer recycled content.

• Avoid carpet backings that contain vinyl or polyurethane; consider a cushion-back, PVC-free alternates, and backings that do not contain fly ash (Ecoworx, WellBAC, CQuestBio etc.).

• Look for carpets that don’t use fluorinated (PFAS-baesd) stain-repellent treatments.

• Prefer ceramic tiles manufactured in the USA to avoid glazes containing toxic lead compounds.

• For rubber flooring: Avoid post-consumer recycled content especially that derived from recycled tires (crumb rubber).

FURNITURE:

• Prefer products that meet BIFMA LEVEL standards.

• Look for SCS Indoor Advantage Gold certifications for low VOC emissions.

INTERIOR PAINT:

• Specify water-based paints whenever possible.

• Look for paints that have VOC emission testing and meet the requirements of the CDPH (California Department of Public Health) Standard Method for Testing VOC Emissions.

• Prefer paints that meet the Green Seal-11 (GS-11) standard from 2010 or later whenever possible or specify paints known to be free of alkylphenol ethoxylates (APEs).

• Avoid paints marketed as antimicrobial and claiming to provide a health benefit.

UPHOLSTERY:

• Specify PVC-free coated fabrics instead of vinyl, consider polyurethane or silicone instead.

• Avoid upholstery with added flame retardents containing PFOAs or HFRs. • Prefer fabrics that are finish-free and don’t have added stain-repellant chemicals.

• Prefer products that provide Health Product Declarations.

Harbor Point Cape Cod, MA

RED-LIST CHEMICAL GUIDE Bisphenol A (BPA)

Used primarily in the production of polycarbonate plastics and epoxy resins. Health effects include endocrine disruption, heart disease, thyroid disruption, cancer, and many other negative long-term impacts.

Found in: Epoxy resins, polycarbonate plastics, grout, adhesives, some paints & powder coats

Formaldehyde

Strong-smelling, flammable gas that is often mixed into chemical compounds to be used in a wide spectrum of products. It is known to cause burning sensations in the eyes & throat, nausea, difficulty breathing, and can even trigger asthma attacks.

Found in: Plywood, pressed-wood, adhesives, paper product coatings, some fiberglass & mineral wool batt insulations

Halogenated Flame Retardants (HFR)

Chemicals added to products to delay or prevent ignition and spread of fire. Halogens are chemicals such as Bromine, Chlorine, Fluorine, and Iodine, commonly included in flame retardants. HFR’s are a human health concern and are associated with reduced fertility, birth defects, reduced IQ, and hormonal changes. Treated products cannot be recycled at the end of their life, thus resulting in landfill waste or incineration which releases toxins into the air, water, and soil, impacting food and water supplies.

Found in: Furniture foam, textiles, insulation

Hexavalent Chromium

Toxic form of chromium known as CR6 & Hex6 in the environment that occurs naturally, but is primarily produced by industrial processes. Hex6 is a human carcinogen which leads to a wide variety of health impacts ranging from lung cancer to liver damage.

Found in: Chrome plating, anti-corrosion coatings, some stainless steel

Pthalates

Known as plasticizers, used to make plastics more flexible or resilient. They can be easily released into the environment because they are not chemically bound to products which can cause evaporaton during use, resulting in human exposure. They are a carcinogen and exposure can lead to hormone disruption, asthma, allergies, and reproductive problems. Found in: Vinyl Products including wallcoverings, carpet backings, paints & coatings, adhesives, caulks, glues

Poly Vinyl Chloride (PVC)

The World’s third-most produced synthetic plastic polymer. Production and burning of PVC results in release of toxins including dioxins which can cause a wide range of health effects including cancer, birth defects, diabetes, endometriosis, etc. with potent carcinogens that the human body absorbs through inhalation. PVC is linked to respiratory ailments, increases the risk of cancer, and contributes to the degradation of indoor air quality.

Found in: Vinyl products including wallcoverings, carpet backings, PVC pipes, and upholstery

RED-LIST ALTERNATIVES Bisphenol A (BPA)

; Look for BPA-Free Labels. ; Avoid harmful BPA-Free alternatives like BPS. ; Use PET Plastics instead. ; Avoid epoxy resins and search for green alternatives.

Formaldehyde

; Request “no added formaldehyde” when specifying composite woods such as plywood and MDF. ; Consider composite wood products that use soybean protein binders or resins.

Halogenated Flame Retardants (HFR)

; Avoid selecting textiles containing HFR’s. ; Carnegie has a great selection of textiles that are finish-free. ; Look for fabrics that are inherently flame resistant. ; If flame retardants are required, look for Compro FR-60, a safe, non-toxic, non-halogen flame retardent.

Hexavalent Chromium

; Use anodized aluminum as an alternative to chrome plating when possible. ; Ask manufacturers of steel stud framing and ductwork to eliminate the “passivation coating” which contains hexavalent chromium (Cr6). Request RoHS (Restriction of Hazardous Substances) compliance. ; Trivalent Chromium (Cr3) plating is a safer alternative and is not as strictly regulated which reduces overhead costs. Information about the full environmental and human health effects has not yet been heavily researched, so caution should be taken. ; See the Miller-Hull Red List for additional alternatives to Hexavalent Chromium.

Pthalates

; Use alternatives to Vinyl flooring such as rubber, bio-based LVT, linoleum or LPT (Luxury polyolefin tile) flooring. ; Look for paints and lacquers that are marked as pthalate-free. ; Select carpet backings made from recycled PET plastics or glass, or select a foam cushion-back.

Poly Vinyl Chloride (PVC)

; Specify upholstery that is PVC-Free, use alternatives such as Polyurethane or Silicone. ; Use alternatives to Vinyl flooring such as rubber, bio-based LVT, linoleum, cork, or polyolefin flooring. ; Select carpet backings that are PVC-Free, made of bio-based materials or recycled PET Plastics. ; When specifying windows, avoid Vinyl frames, use fiberglass, aluminum or wood instead. ; Avoid window treatments containing PVC, instead select shades made of Olefin or Polyester.
