The office was smelling like rotten eggs and I was told to pour bleach down the drain...that combo released strong fumes which had me coughing.  I did evacuate the office for about 1/2 hr and the smell was less...can bleach fumes cause me any harm or permanent damage
Thanks for your question on Chat Doctor. I can understand your concern. Bleach fumes can cause irritation of air passage and coughing. This is normal. So no need to worry about your coughing. Just inhale fresh air and Chat Doctor.  No need to worry about any serious permanent lung damage by this kind of short term exposure. Usually permanent lung damage occurs after years of exposure with toxic fumes. So in your case no need to worry much. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
