Exposure to MDI During the Process of Insulating Buildings with Sprayed Polyurethane Foam

摘要

Buildings are often insulated with sprayed-in-place polyurethane foam in spite of the fact that few studies have been carried out on exposure levels to isocyanates during the spraying process. This paper is meant to provide new data on personal exposure to methylene-bis (4- Phenylisocyanate) (MDI) while dwellings and office buildings are being insulated with Polyurethane foam. An impinger suing a 1-(2-methoxyphenyl) piperazine toluene solution as Absorbent was used to take personal samples for the sprayer and helper during indoor and Outdoor applications.
