About this file
This is a Banned Materials List issued by the National Oceanic and Atmospheric Administration's Global Monitoring Laboratory as of September 2024. The document identifies prohibited chemicals and compounds for use at the Atmospheric Baseline Observatory facility located at 325 Broadway in Boulder, Colorado.
The list encompasses ten categories of banned substances: Chlorofluorocarbons (CFCs) such as CFC-11, CFC-12, and CFC-113; Hydrochlorofluorocarbons (HCFCs) including HCFC-22 and HCFC-141b; Hydrofluorocarbons (HFCs) such as HFC-134a and HFC-152a, including blended refrigerants like R-404a, R-507a, R-410a, and R-407c; Perfluorinated Compounds (PFCs) including carbon tetrafluoride and hexafluoroethane; Halons used in fire suppression systems; Chlorocarbons such as chloroform and carbon tetrachloride; Bromocarbons including methyl bromide; Hydrocarbons such as benzene and toluene; Iodocarbons; and Other compounds including nitrous oxide, sulfur hexafluoride, and next-generation refrigerants HFO-1234yf and HFO-1234ze. Each category provides the molecular formula, chemical name, and common trade names or designations. The document notes that typical construction applications containing these banned compounds include insulation sheets, blown foam insulation, and solvents, sealants, and adhesives such as glues, caulks, paints, and paint thinners.
