Proposal to List Spray Polyurethane Foam Systems with Unreacted Methylene Diphenyl Diisocyanates as a Priority Product

Action:

The Department of Toxic Substances Control (DTSC) is seeking public comment on the proposal to list Spray Polyurethane Foam Systems with Unreacted Methylene Diphenyl Diisocyanates as a Priority Product in regulation.


Summary:

DTSC proposes to list Spray Polyurethane Foam Systems with Unreacted Methylene Diphenyl Diisocyanates as a Priority Product in regulation because workers and consumers could be exposed to unreacted methylene diphenyl diisocyanates during normal use of spray polyurethane foam systems. Inhalation and dermal exposure to unreacted MDI is associated with adverse health effects, including asthma and allergic sensitization. People who become sensitized to MDI may also experience life-threatening asthma attacks when subsequently exposed to extremely low levels of isocyanates.

The primary goal of DTSC’s Safer Consumer Products (SCP) program is to reduce human and environmental exposures to toxic chemicals in consumer products. We use a science-based process to evaluate the use of hazardous chemicals in consumer products and consider routes of exposure to these chemicals throughout the full life-cycle of the product. By listing SPF systems with unreacted methylene diphenyl diisocyanates as a Priority Product, DTSC is requiring manufacturers to answer two questions: 1) Is this chemical necessary? 2) Is there a safer alternative?
