The SPFA and the ACC Center for the Polyurethanes Industry have finalized a new joint document - Guidelines for Exterior High-Pressure SPF Insulation Applications Health and Safety Q&A. This document was produced by joint member companies and describes general guidelines for exterior (i.e., applications done on the outside of a building) spray polyurethane foam (SPF) application. These guidelines are different than those used for interior applications where airborne chemical concentrations may accumulate during application. Outside applications tend to dissipate the chemical concentration levels because of large volumes of air.
These general guidelines are intended to supplement specific and detailed information from the spray foam manufacturer (i.e., Safety Data Sheet and Product Data Sheet) that you are using for installation at a job site.
