{怎么预防苯中毒}

苯(C6H6)为无色、具有特殊芳香气味的液体，相对分子质量78.1，沸点80.1，极易挥发。微溶于水，易溶于乙醇、乙醚、氯仿、丙酮、二硫化碳等有机溶剂。

　　吸人较低浓度的苯蒸气，对呼吸道有轻度刺激作用，作用于神经系统，引起倦睡、眩晕、头痛、头昏、恶心、动作协调能力下降。高浓度苯引起判断和感觉能力下降，平衡觉障碍、耳鸣、意识丧失、死亡，麻醉作用表现突出。

　　苯对眼睛有刺激作用。对皮肤有脱脂作用，可引起炎症、起疱、干燥和表皮脱落。

　　预防措施

　　①用无毒或低毒物质代替苯。

　　②改革工艺，减少接触，如采用电喷漆。

　　③加强通风排毒和个人防护，定期侧定苯的浓度。

　　④经常对生产设备进行维护和检修，防止跑、冒、滴、漏。

　　⑤急需进人检修时需使用正压式空气呼吸器，并应有人在现场监护。

　　⑥进人可能存在苯的场所，必须遵守操作规程，佩戴防毒面具。
