Workplace exposure to rosin-based solder flux fume during hand soldering

摘要

The patterns and extent of exposure to rosin based flux fume have been investigated in two surveys and a number of individual site visits carried out by the UK Health and Safety Executive (HSE). Determination of solder fume was by measurement of airborne resin acid particulate. Both static and personal sampling was carried out over periods ranging from 15 minutes to several hours. Resin acid concentrations were found to vary from less than 1μgm~-3 to 2289μgm~-3. The effects of various types of local exhaust ventilation on resin acid concentrations have been observed.
