The United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry was concerned about the numerous occupational hazards to which its members were exposed and therefore wanted to determine whether unusual mortality patterns could be identified among its membership. The National Institute for Occupational Safety and Health undertook a mortality analysis of the United Association's members and found significant excesses of cancer of the esophagus and of the respiratory and lymphatic systems among those in the plumbing trade. Although plumbers are potentially exposed to several known and suspected carcinogens, additional study is needed to further document the excesses and to determine whether these excesses can be related to specific occupational exposures.
管道安装和管件行业熟练工与学徒工联合协会担心其成员面临众多职业危害，因此希望确定在其成员中是否能发现异常的死亡模式。美国国家职业安全与健康研究所对该联合协会的成员进行了死亡率分析，发现从事管道行业的人员中，食管癌、呼吸系统癌和淋巴系统癌的死亡率显著过高。尽管管道工可能接触多种已知和疑似致癌物，但还需要进一步研究来进一步证实这些过高的死亡率，并确定这些过高的死亡率是否与特定的职业暴露有关。
