This substance is emitted during spraying of a polyisocyanate (a mixture of MDI polymers) and a polyhydroxyl compound (resin) to form a rigid polyurethane foam used for thermal insulation in buildings. The permissible exposure value (PEV) for MDI (monomer form) in Québec is 0.051 mg/m3 (51 ?g/m3). This substance has been identified as a sensitizer (S) in the Regulation respecting occupational health and safety (RROHS) (Règlement sur la santé et la sécurité du travail RSST), which also mentions that the exposure should be kept at a minimum (ME).Field studies (on-site spraying) reported in the scientific literature have shown significant concentrations of MDI during this process, particularly in the residential construction sector.
