Under the provisions of the Workplace Hazardous Materials Information System, workers in Canada must be provided with accurate and comprehensive Material Safety Data Sheets (MSDSs) describing controlled products used in the workplace. As part of an ongoing auditing project, the MSDSs of some controlled products in use under federal jurisdiction were assessed for accuracy and completeness of their ingredient disclosures. Chemical analyses of samples using gas chromatography-mass spectrometry, infrared spectrophotometry, X-ray fluorescence, and wet methods, were performed to verify the ingredient disclosures in accompanying MSDSs. In this article, analytical processes and results are presented for three cases in which MSDS ingredient disclosures were incomplete. The products included a synthetic lubricant used in a mining operation, a detergent concentrate used for aircraft cleaning, and an epoxy reducer used in aircraft maintenance. In each case, undisclosed hazardous ingredients were detected at concentrations which required their disclosure. In at least one of these cases, the information provided in other sections of the MSDS failed to adequately describe the hazards and required protective measures for the composition discovered. Because the results suggest circumstances in which the inaccurate MSDS could act as a mechanism for workplace injury, compliance measures including employer, inspector, and user education, improved MSDS writer qualifications, and the incorporation of chemical analysis in active auditing programs are recommended.
根据《工作场所危险材料信息系统》的规定，必须向加拿大的工人提供准确而全面的物质安全数据表（MSDS），以描述工作场所使用的受控产品。作为一个正在进行的审计项目的一部分，对联邦管辖下正在使用的一些受控产品的MSDS，就其成分披露的准确性和完整性进行了评估。使用气相色谱-质谱联用仪、红外分光光度计、X射线荧光光谱仪和湿法对样品进行了化学分析，以核实随附MSDS中的成分披露情况。在本文中，介绍了三个MSDS成分披露不完整案例的分析过程和结果。这些产品包括一种用于采矿作业的合成润滑剂、一种用于飞机清洁的浓缩洗涤剂，以及一种用于飞机维修的环氧稀释剂。在每个案例中，均检测到了未披露的危险成分，其浓度达到了需要披露的程度。在这些案例中，至少有一个案例里，MSDS其他部分提供的信息未能充分描述所发现成分的危害以及所需的防护措施。由于结果表明在某些情况下，不准确的MSDS可能成为导致工作场所受伤的一个因素，因此建议采取合规措施,包括对雇主、检查员和用户进行教育，提高MSDS编写人员的资质，并将化学分析纳入现行的审计计划中。
