在使用强酸时需要注意哪些问题?

在化学工业中将硫酸、盐酸和硝酸称为三强酸。小型制氧机进行碱液利用率测定时，需要使用硫酸或盐酸。在进行冷却器管束除水垢时，通常使用稀盐酸。强酸具有强烈的腐蚀性，触及皮肤会造成严重灼伤，难以治愈，而且还能引起腐蚀性中毒。因此在使用时应注意下面几点： 　　 　　1)使用强酸时应穿耐酸防护衣，戴橡皮手套。 　　 　　2)量取强酸时要用量筒，绝对不要用吸液管。 　　 　　3)稀释酸时，一定要把浓酸慢慢地沿器壁倒入水中，并且边倒边搅拌，使产生的热量迅速扩散，切不可把水倒入在敞口容器的浓酸里。否则会引起水局部剧烈沸腾，浓酸飞溅，造成灼伤事故。一旦发生酸溅到皮肤或衣服上，应立即用大量水冲洗。然后再用稀碳酸钠(纯碱)溶液冲洗。 　　 　　4)强酸的化学性质很活泼，所以盛酸的瓶子应该密封，并要加以保护，以防破裂。盛酸的瓶子不得受热或日光晒，更不允许接触可燃物。 　　 　　5)发生强酸腐蚀性中毒的症状是唇、口灼伤，喉和胃灼痛，还会发生呕吐或窒息。此时应用小苏打、苦土、石灰水或肥皂水作为解毒剂。
