顺酐车间确实存在有毒物质。顺酐（马来酸酐）是一种无色、有刺激性气味的白色晶体，具有腐蚀性和刺激性，并且遇火可以燃烧。其蒸汽和粉尘与空气混合可能形成爆炸性气体，与氧化剂接触或遇高热、明火有引起燃烧的危险。

　　There are indeed toxic substances in the maleic anhydride workshop. Maleic anhydride (MA) is a colorless, pungent white crystal that is corrosive and irritating, and can ignite when exposed to fire. Its steam and dust mixed with air may form explosive gases, which pose a risk of combustion when in contact with oxidants or exposed to high heat or open flames.

　　在顺酐过程中，使用的原料苯和催化剂具有毒性，可能造成严重的中毒伤害。此外，维修人员在未采取适当措施的情况下进入含有残留有毒蒸气的密闭容器，如反应釜、储罐等，也可能发生中毒事故。

　　In the production process of maleic anhydride, the raw materials benzene and catalysts used are toxic and may cause serious poisoning injuries. In addition, maintenance personnel entering sealed containers containing residual toxic vapors, such as reaction vessels, storage tanks, etc., without taking appropriate safety measures, may also result in poisoning accidents.

　　因此，在顺酐车间工作时，必须采取适当的防护措施，如佩戴适当的呼吸防护装备，并严格遵守操作规程，以防止中毒事故的发生。如果不幸接触到顺酐，应立即采取急救措施，并及时就医。

　　Therefore, when working in the maleic anhydride workshop, appropriate protective measures must be taken, such as wearing appropriate respiratory protective equipment and strictly following safety operating procedures, to prevent poisoning accidents from occurring. If unfortunately in contact with maleic anhydride, first aid measures should be taken immediately and medical attention should be sought promptly.
