During paint application it is inevitable that the
concentration of solvent vapour builds up and may exceed the
Occupational Exposure Standard (OES). This investigation reports
compares vapour concentrations attained during application of
solvent- and water-borne interior building paints.
The study showed that water-borne paints do not give rise to
solvent vapour concentrations in excess of the OES even when
applied under unventilated conditions.
In contrast, solvent-borne paints under unventilated
conditions nearly always gave solvent vapour concentrations in
excess of the OES. One important exception was an isoparaffin
based paint where the OES was not exceeded.
The overall conclusion of the study was that there were
considerable health and safety advantages in using water-borne
interior building paints in place of their solvent-borne
equivalents and that in the majority of cases this substitution
did not involve unacceptable cost or performance limitations.
