Today in a local daily, I read a person died two days after drinking sanitary fluid phenyl, assuming it as fruit juice. Earlier, I heard from a friend about his relative drinking hydro chloric acid (HCl) in a bottle assuming it as water and developing blisters in the mouth. Before that, I heard another incident of a boy taking water from a jug placed on a water cooler, that was used earlier for phenyl and had symptoms of stomach burning for few days. There were many lab incidents due to the use of a chemical that is not same as the label on the bottle.
All above incidents stress on importance of proper labeling, safe procedure for handling of chemicals, proper hygienic practices and supervision. Otherwise, such incidents keep recurring at regular intervals.
