Fairfax, Virginia -- The Spay Polyurethane Foam Alliance (SPFA) won a bid to have California Department of Toxic Substances Control (DTSC) correct information in public documents.
The information was distributed by the agency as part of its Safer Consumer Products Priority Products Initiative. The organisation lobbied against details using DTSC’s own data, which it said “indicates the incorrectness of the statement” regarding asthma risk in the workplace.
Kurt Riesenberg, executive director of the SPFA, said: "The SPFA is pleased that these critical changes were completed to these public documents, as the facts put forth in the initial documents were grossly incorrect and have caused irreparable harm to our members and the building industry in the state of California.”
The DTSC revised the contentious and incorrect statement in its Product Profile that read "diisocyanates are the leading attributable cause of asthma in the workplace" to state "exposure to diisocyanates in the workplace can cause asthma."
The department altered the definition of spray polyurethane foam systems, narrowing it to include only pressurised two-component systems utilised to make SPF.
Additionally, the definition includes two-component systems marketed for insulation and roofing applications, however now excludes roof coatings.
The department has excluded one-component spray polyurethane foam systems sold in cans from the official list being evaluated.
The DTSC has removed HDI and TDI, isocyanates utilised in some elastomeric roof coatings but not in the A-side of SPF systems, from the scope of the Chemicals of Concern documentation.
The Department has deleted certain reference documents from the Priority Product File.
