Steps
Review EPA Safer Choice's SPF guidance (now hosted at archive.epa.gov/epa/saferchoice/... — moved to EPA's official archive server but still EPA-authored technical content) alongside CPSC's current "Spray Polyurethane Foam Insulation: Health and Safety Recommendations for Consumers" PDF as a non-archived companion source.
Confirm all installers/helpers complete isocyanate-specific health and safety training and follow label/SDS directions before spraying MDI/pMDI-based two-component SPF.
Set and communicate re-entry and re-occupancy times to the client — guidance commonly cites roughly 24 hours for two-component high-pressure "professional" systems, but always defer to the specific product manufacturer's stated ventilation/re-entry time, which can differ by product.
Use PPE (respiratory, skin, eye protection) during application and follow safer-workplace-practice guidance for ventilation during and after spraying.
Provide the client/occupant a plain-language summary of potential exposure symptoms (asthma, sensitization, respiratory and skin/eye irritation) so they know what to watch for post-installation.
Known gotchas
The EPA Safer Choice SPF pages now live under archive.epa.gov, not the live epa.gov site — treat them as EPA-authored reference material but verify current program status/contacts separately since the pages were relocated.
Re-entry/re-occupancy times are product-specific, not a single universal EPA number — don't quote "24 hours" as a regulatory requirement; it's a common but non-binding manufacturer guideline.
