Table 1 Occupations with exposure to solvents.

Occupation	Intensity of solvent exposure
Dry cleaning, screen printing, rotogravure printing, industrial painting, manufacture of glass reinforced plastic, tile fixing	High exposure
House painting, mechanic, assembly processes using solvents, paint making, industrial degreaser	Moderate exposure
Petrol pump attendant, joiner/carpenter, chemical process operator, laboratory technician, cleaner using polishes	Low exposure

This list is not exhaustive but rather gives an indication of the likely intensity of exposure in a range of occupations. The actual solvent exposure is determined by a number of factors including which solvent is used, in what concentration, the method of use, adequacy of ventilation, and the personal protective equipment employed. For example, a house painter applying water based paint by brush in a well ventilated room will have considerably lower exposure than one spray painting high solvent paint in a poorly ventilated cellar.
