A study was made to evaluate and document the effectiveness of a metal inert gas (MIG) welder with built in ventilation to control potentially hazardous conditions at Church Brother's Collision Repair (SIC-7531), Greenwood, Indiana. Air contaminant exposures were measured during a 1 hour repair job while using a ventilated MIG welder and while using a conventional MIG welder. The ventilation system of the MIG did reduce worker exposure to welding fumes. However, the sampling was done on a single repair job, thus limiting the conclusions which can be drawn from the study. Some welding fumes were not captured by the ventilated welder, suggesting that the MIG with ventilation provided incomplete control of the generated fumes. In some cases the metal on the other side of the welding area became sufficiently hot to generate its own fumes. The car body itself appears to block the capture of these fumes by the ventilated MIG welder. When welding inside the car without the ventilated welder, the fumes generated were more concentrated than those generated by welding outside of the car under similar conditions. There is a decreased dilution of the fumes inside the car due to a lack of air movement. The authors conclude that while the control technique appeared to lessen exposure to welding fumes, additional investigation is needed to verify the data.
