25. Toxic material reduction
Various chemicals are still used in the manufacture of building materials, despite known or suspected health hazards. Flame retardant chemicals, which are used to increase fire-resistance of materials, include PBDEs (polybrominated diphenyl ethers)—which, based on animal tests, are associated with potential neurobehavioral, carcinogenic and immune effects. Some of these chemicals can bioaccumulate in fat and result in food chain contamination, including human milk.
This feature identifies some potentially harmful chemical compounds commonly found in building materials, and suggests avoiding them in certain applications. Refer to Table A3 in Appendix C for specific chemical names and registration numbers.
No perfluorinated compounds (PFCs) are present in the following condition:
Halogenated flame retardants are limited in the following components to 0.01% (100 ppm) to the extent allowable by local code:
DEHP, DBP, BBP, DINP, DIDP or DNOP (often found in polyvinyl chloride [PVC]) are limited in the following components to 0.01% (100 ppm):
Isocyanate-based polyurethane products are not used in:
Urea-formaldehyde presence is limited in the following components to 100 ppm:
