Facebook Pixel Well Materials Feature | Western Kentucky University Skip to main content


Intent: The WELL Materials concept aims to reduce human exposure to hazardous building material ingredients through the restriction or elimination of compounds or products known to be toxic and the promotion of safer replacements. Compounds known to be hazardous to the health of occupational workers and/or known to bioaccumulate or aggregate in the environment are also restricted and in some instances not permitted.


WKU Points Achieved in the Materials Feature


Intent: Reduce or eliminate human exposure to building materials known to be hazardous.

This WELL feature requires the restriction of hazardous ingredient components in newly installed building materials, specifically through the restriction of asbestos, mercury-containing lamps and lead in plumbing products and paint. 

  • Restrict Asbestos
  • Limit Mercury
  • Restrict Lead

Intent: Mitigate environmental contamination and associated exposures to hazardous waste.

This WELL feature requires the safe ongoing management and disposal of hazardous waste, including construction and demolition waste.

  • Manage Hazardous Waste:

    1. A waste stream plan addresses the management of the following hazardous wastes per U.S. Environmental Protection Agency 40 CFR Part 273 Standards for Universal Waste Management, Subpart B or C (as applicable): Batteries, Pesticides, Mercury-containing equipment and lamps.

    2. A waste stream plan includes waste receptacle access, waste or source reduction, recycling and materials recovery , disposal of waste. 

Intent: Reduce exposure to pathogens, allergens and hazardous cleaning chemicals.

This WELL feature requires the restriction of hazardous or harmful ingredients in soap, shampoos, cleaning, disinfection and sanitization products as well as program training for staff, a plan for the maintenance of a cleaning schedule and a protocol for entryway cleaning and maintenance.

  • Low hazard cleaning products:  Cleaning products, soaps, shampoos, disinfection and sanitization products are not manufactured with ingredients classified under the Globally Harmonized System (GHS) for the following endpoints:

    1. Carcinogenic, mutagenic or reprotoxic substances:  H340 (may cause genetic defects), H350 (may cause cancer), H360 (may damage fertility of the unborn child).

    2. Systemic toxicity/organ effects: H372 (causes damage to organs through prolonged or repeated exposure),

    3. Skin and respiratory irritation: H317 (may cause an allergic skin reaction), H334 (may cause allergy or asthma symptoms or breathing difficulties if inhaled).
