Isolate project from occupied space by proving a vapor barrier
In projects retrofitting existing in-use building it is not always practical to evacuate the building occupants for the entire course of the project, especially in projects where the work will be spread over long periods of time. In such cases, properly designed isolation, coupled with positive controlled ventilation, has proven to be an effective engineering solution to safely protect the occupants of a building from polyurethane vapors (Volatile Organic Compounds, VOCs) during the retrofit process. To document the performance of the isolation barriers and ventilation controls, H. C. Fennell Consulting has developed and implements with each project, verification protocols that are rigorous and adequate to assure that these systems are providing the desired protections and that there is no exposure to the occupants. Air quality monitoring is an essential element of the verification protocol. And together with differential pressure
measurements ensures and confirms that occupants are not exposed to any hazardous spray foam fumes.
Provide controlled ventilation to prevent vapors from migrating to the occupied space.
