COMMENTARY
Examples of Acceptable Methods of Implementation and/or Compliance:
Builders should be ready to provide verification of compliance with any portion of this section to the enforcing agency. Compliance information is readily available online and should be accessible if required by an enforcing agency.
It is recommended that a method of compliance be ready and prepared so inspections are not failed or postponed because compliance materials are not available.
Product specifications should be easily accessible from the product and material suppliers.
Make these available at time of inspection.
Contractors should be cognizant that field inspectors can request to field verify that applied products meet the requirements of Section 4.504.3. It is suggested that contractors keep available any containers and/or product labels for inspectors verification until such time the inspector deems they are not required.
Hyperlinks to supporting sample documentation forms are included in Chapter 8. These forms may be used for documenting VOCs and formaldehyde content in adhesives, paints and coatings, flooring and composite wood products used in the structure. These forms should be supplemented by product labels, specifications, Material Safety Data Sheets, evidence of certifications, or other means acceptable to the local enforcing agency. These forms are samples and may be modified by the user as needed.
Background:
All carpet systems, cushions, and adhesives are required to comply with the VOC requirements set forth by Sections 4.504.3, 4.504.3.1 and 4.504.3.2, respectively. This practice will help reduce indoor emission levels thereby improving the overall healthfulness of indoor and outdoor air quality. Installed products used are third party-certified and installed in a manner acceptable to the manufacturer’s requirements.
