第三部分:危险性概述
危险性类别:
侵入途径:
健康危害:
本品对鼻及喉粘膜有刺激性,可致鼻粘膜溃疡。高浓度反复接触可引起神经损害,表现为四肢麻木、无力;尚可引起恶心、腹痛和头痛。严重者可致死。在有酸或酸雾存在时,可产生溶血性毒物砷化氢。皮肤接触可引起烧灼感、刺痒和色素改变。
环境危害:
对环境有危害,对水体可造成污染。
燃爆危险:
本品不燃,高毒,具刺激性。

皮肤接触:
脱去污染的衣着,用肥皂水和清水彻底冲洗皮肤。
眼睛接触:
提起眼睑,用流动清水或生理盐水冲洗。就医。
吸入:
迅速脱离现场至空气新鲜处。保持呼吸道通畅。如呼吸困难,给输氧。如呼吸停止,立即进行人工呼吸。就医。
食入:
催吐。洗胃。给饮牛奶或蛋清。就医。
第五部分:消防措施
危险特性:
不燃。受高热分解放出有毒的气体。暴露于空气中遇二氧化碳逐渐分解。与氧化剂可发生反应。遇酸产生剧毒的三氧化二砷。

氧化砷、氧化钠。
灭火方法:
消防人员必须穿全身防火防毒服,在上风向灭火。灭火剂:干粉、水、砂土。
第六部分:泄漏应急处理
应急处理:
隔离泄漏污染区,限制出入。建议应急处理人员戴防尘面具(全面罩),穿防毒服。不要直接接触泄漏物。小量泄漏:避免扬尘,用洁净的铲子收集于干燥、洁净、有盖的容器中。大量泄漏:用塑料布、帆布覆盖。然后收集回收或运至废物处理场所处置。
第七部分:操作处置与储存
操作注意事项:
密闭操作,提供充分的局部排风。操作尽可能机械化、自动化。操作人员必须经过专门培训,严格遵守操作规程。建议操作人员佩戴自吸过滤式防尘口罩,戴化学安全防护眼镜,穿连衣式胶布防毒衣,戴橡胶手套。避免产生粉尘。避免与氧化剂、酸类接触。搬运时要轻装轻卸,防止包装及容器损坏。配备泄漏应急处理设备。倒空的容器可能残留有害物。
储存注意事项:
储存于阴凉、通风的库房。远离火种、热源。包装密封。应与氧化剂、酸类、食用化学品分开存放,切忌混储。储区应备有合适的材料收容泄漏物。应严格执行极毒物品“五双”管理制度。
