| Abstract |
Styrene exposure and the performance of current ventilation systems were measured in 17 reinforced plastics plants. The characteristics of styrene emission during hand lay-up and the effect of a rolled area on styrene evaporation were also determined. In order to meet the present exposure limit, local ventilation techniques should be used in combination with other control measures. Well-designed zonal ventilation methods produced a favourable airflow pattern for controlling styrene vapours in the lamination area. However, work practices must be synchronized with the airflow pattern before low styrene exposure levels are reached. Styrene control during hand lay-up moulding is also possible with the use of several local exhaust hoods. The use of vapour-suppressed resin reduced the total styrene emission by 30-60%, but the reduction was much lower during active lamination. After rolling, the emission from the vapour-suppressed resin was found to be very low, and, therefore, the emission rate was dependent on the size of the surface area rolled simultaneously. The use of these resins is beneficial, especially when large products are laminated. |
