第三部分:危险性概述
危险性类别:
侵入途径:
健康危害:
具有麻醉作用。动物吸入超过一定浓度时引起血压下降,导致呼吸麻痹而死亡。在工业生产和使用中,本品一般对人体无明显危害。近来国外首例报道一青年因吸入环丙烷而死于一间仓库内。尸解见肺充血和出血性水肿,气管充血,并较早发生细胞自溶现象。
环境危害:
燃爆危险:
本品易燃。
第四部分:急救措施
皮肤接触:
眼睛接触:
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:


第五部分:消防措施
危险特性:
易燃,与空气混合能形成爆炸性混合物,遇明火、高热极易燃烧爆炸。气体比空气重,能在较低处扩散到相当远的地方,遇火源会着火回燃。
有害燃烧产物:
一氧化碳、二氧化碳。
灭火方法:
切断气源。若不能切断气源,则不允许熄灭泄漏处的火焰。喷水冷却容器,可能的话将容器从火场移至空旷处。灭火剂:雾状水、泡沫、二氧化碳、干粉。
第六部分:泄漏应急处理
应急处理:
迅速撤离泄漏污染区人员至上风处,并进行隔离,严格限制出入。切断火源。建议应急处理人员戴自给正压式呼吸器,穿防静电工作服。尽可能切断泄漏源。用工业覆盖层或吸附 / 吸收剂盖住泄漏点附近的下水道等地方,防止气体进入。合理通风,加速扩散。如无危险,就地燃烧,同时喷雾状水使周围冷却,以防其它可燃物着火。或将漏气的容器移至空旷处,注意通风。漏气容器要妥善处理,修复、检验后再用。
第七部分:操作处置与储存
操作注意事项:
密闭操作,全面通风。操作人员必须经过专门培训,严格遵守操作规程。远离火种、热源,工作场所严禁吸烟。使用防爆型的通风系统和设备。防止气体泄漏到工作场所空气中。避免与氧化剂、卤素接触。在传送过程中,钢瓶和容器必须接地和跨接,防止产生静电。搬运时要轻装轻卸,防止包装及容器损坏。配备相应品种和数量的消防器材及泄漏应急处理设备。
储存注意事项:
储存于阴凉、通风的库房。远离火种、热源。库温不宜超过 30 。应与氧化剂、卤素分开存放,切忌混储。采用防爆型照明、通风设施。禁止使用易产生火花的机械设备和工具。储区应备有泄漏应急处理设备。

身体防护:
穿防静电工作服。
手防护:
戴一般作业防护手套。
其他防护:
工作现场严禁吸烟。避免长期反复接触。进入罐、限制性空间或其它高浓度区作业,须有人监护。
