"EPA Considers Ban on Dangerous Chemicals in Spray Foam Insulation"

"The U.S. EPA is considering a ban or restriction on consumer insulation and sealant products containing a family of chemicals known as diisocyantes.

The chemicals are found in spray polyurethane foam, an effective and widely used insulation and air sealant material for insulating walls, sealing concrete or finishing floors.

Exposures to isocyanates such as methylene diphenyl diisocyanate, or MDI, and other SPF chemicals in vapors, aerosols, and dust during and after installation can cause adverse health effects, the agency warns.

"There has been an increase in recent years in promoting the use of foams and sealants by do-it-yourself energy-conscious homeowners, and many people may now be unknowingly exposed to risks from these chemicals," said Steve Owens, assistant administrator for EPA's Office of Chemical Safety and Pollution Prevention."
