现代实验室中的设备和操作要尽量考虑科学家的安全,我们或许认为这是理所应当的。尽管现代实验室中仍然存在事故,但是如果你了解过去的实验室安全状况,你会非常感激自己工作学习在21世纪。在过去,与化学和放射性物质相关的操作并没有任何保护。

现代的实验室看起来已经大大不同。

不要吸得太狠!

很难相信,使用嘴来移液在过去是很常见的技术。移液管几乎是每个实验室必备的设备,它被用于精确地测量液体体积。有很多不同种类的移液管,大部分实验室现在使用移液管具有无菌的一次性吸嘴,能够自动控制体积。这种设备是在上世纪70年代被开发出来并普遍被使用。

在19世纪末和20世纪初,很多科学家用嘴吸移液体!他们使用又长又细的带有刻度的玻璃管,将其伸入盛有液体的烧杯中,然后用嘴将液体吸上来。吸力会使液体向上移动,就像使用吸管喝汽水一样。在达到了想要的体积时停止,使化学物质或者细菌不会进入口中。科学家们通常会在玻璃管顶部用棉花作为屏障,但这并不能降低多少风险。


眼见为实!

首次记录的口吸移液导致的感染发生在1893年,当时一位医生不小心将伤寒杆菌吸入口中。1915年,有40%的实验室感染都是由口吸移液导致的。50年后,尽管人们已经意识到了危害,但是口吸移液仍然非常普遍。口吸移液非常危险,每五次口吸移液就会发生一次感染。所以,经常这么做的话,感染的机率非常高。威胁不仅仅来源于口吸的过程,还来源于蒸气和手指接触。由于口吸移液导致的感染包括伤寒、沙门氏菌、炭疽杆菌、链球菌、梅毒和病毒性肝炎。

口吸转移的不仅仅是传染性微生物,还包括一些腐蚀性的、毒性的物质,甚至是血液。这些物质可能引起化学烧伤或者中毒。即使在今天,实验室安全指导也明确禁止口吸移液,并建议使用机械吸管或者胶皮球吸管,或无菌的吸管辅助器。

还好,感激21世纪的实验室,我们使用的是各种型号的移液枪,远离了这些风险。

遮住你的眼睛!

在透明硬塑料安全护目镜出现之前,很多科学家在处理反应物质时没有眼睛保护措施。Joseph-Louis Gay-Lussac(1778-1850)在研究钾时,一次钾爆炸事件导致他暂时失明,并且视力受到了永久性损伤。从那时起,他所戴的眼镜使他在又一次爆炸中免于受伤。Robert Bunsen (1811-1899)在研究砷化合物时,一瓶氯化二甲胂(C2H6AsCl)在他面前爆炸,导致他一只眼睛失明。从这些教训中我们知道,在处理爆炸物质时一定要戴上护目镜。


我们应该对护目镜心存感激!

不要吸入毒气!

现在几乎所有的实验室都有通风柜,通风孔能吸入烟气,玻璃门上只留下手可以通过的空间。这种设计能够使吸入危险气体的概率降到最低。Robert Bunsen几乎死于氯化二甲胂,这种物质具有爆炸性,还会生成危险气体。另一个因气体受伤的科学家是Humphry Davy (1778-1829),他是第一个尝试分离氟元素的人,这是一种反应性最强的非金属元素。他想要通过电解氟化氢分离出氟元素。毒气使他的眼睛和手指甲受伤。


通风柜能够吸入所有的有害气体

小心化学物质!

现在,在实验室中处理有害化学物质时需要格外注意。过去,人们不清楚这些化学物质的副作用和引发的威胁,所以并没有认真对待。

在不小心尝到了手上残留的化学物质之后,三位科学意外地发生了人造增甜剂。为了弄清楚他们尝到的是哪种物质,他们尝遍了实验室中的所有物质。现在,尝试未知化学物质的危险被人们着重强调,我想不会再有思维正常的人这么做了。

低脂糖的主要成分由Constantine Fahlberg发现,他当时尝遍了实验室中的所有化学物质。他发现苯酰亚胺化合物应该是源头,他把这个化合物命名为糖精。为了验证它是否是安全的,他拿了10克,吞了下去,等了24小时,观察反应。结果发现直接排泄掉了—人的新陈代谢基本上不能吸收这玩意。他认定它是安全的。从那时起,糖精被用于各种饮料,尤其是在第二次世界大战期间缺糖的时候。今天,你可以买到Sweet n" Low的小纸包糖精(代糖)。

另一个著名的例子是居里夫人(1867-1934),她是放射学的先驱。在刚刚发现镭时,她并不知道这种元素对人体的危害,也并没有采取任何保护措施。她所接触到的辐射强度非常高,在100年后,她的笔记本还需要被保存在衬铅的箱子中。她将盛有镭和钋的玻璃瓶放在口袋中和书架上。

居里夫人死于再生障碍性贫血,这种疾病是由过高剂量的辐射引起。与居里夫人共同工作的很多其他科学家死于白血病和其他辐射导致的疾病。

居里夫人全情投入在工作中,没有手套,也不担心。

发现镭之后,有人想出一个主意,用镭写出手表的指针和数字,这样手表就会发光了。这种手表流行一时,很多工厂生产了数百万只这种手表。年轻的女工徒手涂画表盘。她们不知道镭的危害,也没有采取任何防护措施。几年后,很多人生病了,一些人患上骨癌,他们的身体具有放射性,这最终导致他们死亡。

这个表盘是用镭画的

以上都是科学家前辈们用身体甚至生命总结出来的关于实验室操作的安全问题。现如今的实验室已经是非常安全的了,但是也请严格执行实验室各项规范。小心驶得万年船!

东华大学一实验室爆炸,警惕实验室这四毒

今天,位于松江大学园区的东华大学化学化工与生物工程学院一实验室发生爆炸,两名学生受重伤,暂无教师受伤。目前爆炸原因仍在进一步调查中,现无法判断是物理性的高温高压因素,还是实验品的化学反应因素,或者是实验人员操作不当的人为因素造成爆炸。 近年来,高校实验室安全事故时有发生。据说,本次东华大学实验室是在取浓硫酸时开盖即炸的,实验室就是神雕侠侣里的“绝情谷”,遍地是毒,稍不注意

实验室里的坏习惯,中招了没?

实验完成后不及时清理现场,实验台面用过后不打扫,总留给别人一个烂摊子。枪乱放,不放回枪架。用过的平板、培养液也随手乱扔。称量天平那儿常常一片狼藉。超净台里枪头溅出也不收拾。跑电泳的地方都是用过的凝胶…… PCR电泳完后剩下的东西不及时的清理,别人又不知道是不是该扔,时间长了会占用架子的。说到架子,喜欢把自己的东西放在EP管架子上而不是盒子里就放入冰箱,而使架子不够用。 自己的实验结
