披露矿场安全和

卫生行政部门安全数据

我们经营一座位于阿拉戈斯工厂的盐矿，直至2019年5月，如我们年报的“项目4.本公司-可报告部门--我们巴西部门的原材料-盐”中所述。该矿使用井系统提盐，没有任何工人 暴露在矿井内部。由于该矿位于巴西，因此它不受《1977年联邦矿山安全与健康法》或《矿产法》下的《矿山安全与健康管理局》(MSHA)的监管，我们的采矿作业也不受该法规的约束。此外，在2023财年，我们的采矿作业均未收到来自MSHA的书面通知，涉及(I)违反《矿业法》第104条或矿山经营者不遵守《矿业法》第104(D)条；(Ii)公然违反《矿业法》第110(B)(2)条；(Iii)根据《矿业法》第107(A)条发出迫在眉睫的危险命令；(Iv)根据采矿法进行的拟议评估或(V)违反强制性健康或安全标准的行为模式，而违反行为的性质可能导致矿业法第104(E)条规定的矿山健康或安全危害的前因后果，或有可能出现此类模式。

在2023财年，我们没有发生任何与采矿有关的事故，也没有涉及联邦矿山安全与健康审查委员会 涉及我们的矿山或采矿作业的任何悬而未决的法律诉讼。

Braskem’s mining operations in the State of Alagoas held an environmental license issued by the State’s environmental protection agency valid through March 31, 2022, and are grounded in mining law formalized by the Mining Concession awarded by the Federal Government of Brazil. In view of the summarized report issued by the Mineral Resources Research Company (CPRM), an agency of the Brazilian Ministry of Mines and Energy, on May 8, 2019, we voluntarily suspended the salt extraction activities at the wells that were the object of the environmental licenses on such date. On May 9, 2019, we received two separate orders to cease operations issued by the Institute for the Environment of the State of Alagoas (IMA), a state-level environmental regulatory agency, and the National Mining Agency (ANM), the Brazilian federal regulatory and oversight agency for mining activities, both of which we complied with.
