This post can serve as precaution in the Laboratory as well as in the house. Do you know that there are some household cleaning products that contain ammonia?. The only way to differentiate the one that contains bleach and the one that contains ammonia is to look at their label so that you won't go and mix them together. Besides, urine contains ammonia and if it mistakenly get in contact with a bleach in the house there will be formation of chloramine gas which is very dangerous for human health as explained above.
