Exposure to chlorophenols occurs in the vicinity of the lumber treatment area in sawmills and in subsequent work phases where treated lumber is handled. Measurements from several countries indicate that the concentration of chlorophenols in the workroom air is generally below 0.5 mg/m3, the occupational exposure limit of chlorophenols in many countries. Inhalation usually leads to relatively low concentrations of chlorophenols in urine of exposed workers. Frequent skin contact with chlorophenol solution or with freshly treated lumber can produce urine concentrations 10-100 times higher than among those with inhalatory exposure only. In addition to chlorophenols, exposure to toxic polychlorinated dibenzodioxins and dibenzofurans may occur in some tasks carried out in sawmills. Jobs with potentially heavy exposure include the treatment of dipping-vat sludge and processes involving heating of chlorophenols, such as burning of treated waste wood and welding of metal structures contaminated by chlorophenols.
在锯木厂的木材处理区域附近以及后续处理已处理木材的工作阶段会接触到氯酚。来自多个国家的测量结果表明，车间空气中氯酚的浓度通常低于0.5毫克/立方米，这是许多国家氯酚的职业接触限值。吸入通常会导致接触工人尿液中氯酚的浓度相对较低。频繁皮肤接触氯酚溶液或新处理的木材会使尿液中氯酚的浓度比仅通过吸入接触的人高出10至100倍。除了氯酚，在锯木厂进行的一些任务中可能会接触到有毒的多氯二苯并二恶英和二苯并呋喃。潜在高暴露的工作包括处理浸渍槽污泥以及涉及氯酚加热的工艺，如燃烧处理过的废木材和焊接被氯酚污染的金属结构。
