作者&投稿：拱壮 （若有异议请与网页底部的电邮联系）
TDI: 甲苯二异氰酸酯 ,剧毒化学品，剧毒品编号：14
危险化学品编号：61111；UN ID: UN2078；CAS号：584-84-9
使用此化学品，需安监局和公安局备案后，方可使用
甲苯二异氰酸酯属于危险且剧毒化学品，属于甲类，需要办理危险化学品经营许可证。
甲苯二异氰酸酯具有强烈的刺激性气味，在人体中具有积聚性和潜伏性，对皮肤、眼睛和呼吸道有强烈刺激作用，吸入高浓度的甲苯二异氰酸酯蒸气会引起支气管炎、支气管肺炎和肺水肿。
液体与皮肤接触可引起皮炎。液体与眼睛接触可引起严重刺激作用，如果不加以治疗，可能导致永久性损伤。长期接触甲苯二异氰酸酯可引起慢性支气管炎。

甲苯二异氰酸酯泄漏应急处置
根据液体流动和蒸气扩散的影响区域划定警戒区，无关人员从侧风、上风向撤离至安全区。建议应急处理人员戴正压自给式空气呼吸器，穿防毒服。
作业时使用的所有设备应接地。穿上适当的防护服前严禁接触破裂的容器和泄漏物。尽可能切断泄漏源。防止泄漏物进入水体、下水道、地下室或密闭性空间。
严禁用水处理。小量泄漏：用干燥的砂土或其它不燃材料覆盖泄漏物。大量泄漏：构筑围堤或挖坑收容。用泵转移至槽车或专用收集器内。
