Abstract
The performance of a commercially available Local Exhaust Ventilation (LEV) system for controlling mist, vapor and fume exposures during two-piece slim retractable aluminium can production line was assessed. This study focused on monitoring of LEV system performance in different phases of production which are drawing and wall ironing. Data such as static pressure, velocity pressure, transport velocity and flow rate values was obtained as a specific requirement to analyze the performance of the system. The first LEV system used to control mist exposure from drawing activities and the second system was implemented to control fume and vapor during ironing wall process. The performance of the system was investigated and compared with standard as required by USECHH Regulation 2000. The results of LEV system monitoring were discussed and several recommendations were proposed to improve the performance of the system and to reduce the mist, fume and vapor exposure for occupational safety and health purposes.
