26. Enhanced material safety
Many chemicals used in building materials have not been fully evaluated for safety and may be known or suspected carcinogens, mutagens, or endocrine, developmental and reproductive disruptors. Voluntary programs in the market allow suppliers that have carefully screened the composition of their products and avoided potentially harmful substances to be recognized for their achievements.
This feature promotes the use of products that have been independently verified to be free of many suspected hazards.
At least one of the following requirements are met:
