8.2 Exposure controls
Engineering controls: Use local exhaust ventilation, or other engineering controls to maintain
airborne levels below exposure limit requirements or guidelines. If there are no applicable exposure
limit requirements or guidelines, general ventilation should be sufficient for most operations. Local
exhaust ventilation may be necessary for some operations.
