苯的应急处理与个人防护 | 2012-4-26 8:19:00

苯(C6H6)

　　【理化性状和用途】

　　无色透明，易燃液体。分子式:C6H6 比重:0.8794 熔点:5.51℃ 沸点:80.1℃,闪点:-0.11℃, 自燃点:562.22℃。蒸气与空气混合物爆炸极限:1.4~8.0%。不溶于水。遇热源、明火燃烧爆炸。

　　主要用于制造洗涤剂、杀虫剂和油漆清洁剂，苯可作为汽油一部份。

　　【毒性及燃爆性】

　　急性中毒作用主要有抑制中枢神经系统。高浓度蒸气对粘膜和皮肤有一定的刺激作用。液态苯直接吸入呼吸道，可引起肺气肿和出血。苯蒸气经呼吸道吸入的最初几分钟吸取率最高。

　　高度易燃性。有严重火灾危险。用干粉、泡沫灭火剂、二氧化碳灭火。蒸气能沿地面流动到火源处并回火，属于甲类火灾危险品。

　　【个人防护装备-PPE】

　　吸入：如蒸气火烟雾浓度不明时会爆炸。高浓度时应戴用褐色色标滤毒罐的防毒面具。紧急事态抢救物质及人员撤离时，佩带自给式呼吸器。

　　皮肤: 如需要应使用手部防护-手套、身体防护-防护服/工作服、足部防护-安全鞋/防化靴。

　　眼睛: 戴用化学防溅镜或面罩。

　　其它: 工作现场严禁吸烟、进食和饮水。工作后淋浴更衣，保持良好的卫生习惯。

　　【储存、运输及使用】

　　遵守储藏和运输易燃物质的规则, 储藏于密闭的、置于地面上的容器内, 放置在有通风设备的阴凉地方, 避免阳光直晒, 远离禁忌物与热源, 采用无火花的通风系统和电气设备.

　　使用“用毒品”、“易燃物品”标志。

　　【应急处理】

　　吸入: 脱离苯产生源或搬移患者至空气新鲜处, 如患者停止呼吸应进行人工呼吸.

　　眼睛接触: 使眼睑张开,用生理盐水或清水冲洗患眼至少20分钟.

　　皮肤接触: 脱去受污染的衣服, 立即缓和地抹去和擦去残余物质, 缓和、充分地用水和无摩擦性肥皂洗涤.

　　口服: 用水充分涮口, 不可催吐, 给患者饮水250毫升.一切患者都应请医生治疗.

　　【应知应会】

　　苯为无色透明、易燃液体。

　　吸入或口服大量苯后出现兴奋或酒醉感。

　　长期接触对造血系统造成危害。

　　防护需佩带褐色色标的放毒面具和身体防护-防护服/工作服、手部防护-手套、足部防护-安全鞋/防化靴等。

　　中毒者脱离产生源至新鲜空气处，一切患者应请医生治疗。

　　工作现场严禁吸烟、进食和饮水。
