A task group has been formed to respond to specific issues and to conduct testing of generic products to demonstrate the safe use of SPF on a variety of plastic pipe and wiring insulation. Contact SPFA for more information at 800-523-5164.

mason Posted: Jan 25, 2008 01:32 PM	Right now they have identified a list of what they perceive to be the most critical issues and are addressing those first. But, I would call SPFA and ask Kurt about your specific inquiry. The more inquiries about one issue, the higher it goes on the list.
