California issues DINP safe use determination for PVC roofing

时间:2015-12-07 10:33 点击:

California's Office of Environmental Health Hazard Assessment (Oehha) has issued a safe use determination (SUD) for the use of diisononyl phthalate (DINP) in certain roofing applications.

Based on its analysis, Oehha concluded that a Proposition 65 warning for the installation of single-ply polyvinyl chloride (PVC) roofing membranes is not required. It found that the reviewed exposure scenario to DINP, during installation, resulted in an excess cancer risk of less than one in 100,000, and an exposure to only 57 percent of the proposed No Significant Risk Level (NSRL) for the substance.

DINP is an intentionally added plasticiser that provides flexibility to single-ply PVC roofing membranes, and is present at concentrations of up to 15% of the product's total weight.

It was listed in December 2013 as a substance known to the state to cause cancer.

The SUD was developed at the request of the Chemical Fabrics & Film Association (CFFA) earlier this year.
