This report describes a six month project carried out by PRA,
on behalf of the HSE, to provide experimental data on the
build-up of solvent vapour in a room during roller painting. The
data will be used by AEA Technology Consultancy Service to
validate a risk assessment computer model, developed for HSE.
PRA made-up four paint systems, three based on a single
hydrocarbon solvent and one a mixture of decane, nonane and
octane. The vapour concentration at three heights were determined
under conditions of zero, medium and high ventilation.
For the paint based on the hydrocarbon solvent mixture the
concentration of each component was determined. Drying times were
determined according to BS 3900 : Part C and hard drying time
according to BS 3900 : Part C3.
The results are as expected, the lower the ventilation, the
higher the solvent concentration and the lower the molecular
weight of the solvent, the faster the initial rate of
evaporation.
