Spray polyurethane foam (SPF) is an effective insulation and air sealant material; however, exposures to its key ingredient, isocyanates such as "MDI," and other SPF chemicals that may be found in vapors, aerosols, dust or on surfaces during and for a period of time after installation may cause adverse health effects such as asthma. Therefore, steps to control exposures and safety tips should be followed.

Information on these Web pages is aimed at helping to ensure the safety of SPF applicators and building occupants where SPF is installed. It is also aimed at providing safety and scientific information to professionals in business, non-governmental organizations, academic institutions, and regulatory agencies.
