Inhalation: Corrosive! Inhalation of vapors can cause coughing, choking, inflammation of the nose, throat, and upper respiratory tract, and in severe cases, pulmonary edema, circulatory failure, and death.
First Aid Measures
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately.

Muriatic (hydrochloric) acid is a strong acid and the fumes can be very irritating. While I don't know the circumstances he encountered, I can't believe he inhaled enough of the fumes to cause permanent damage. Hydrochloric acid has an extremely acrid and pungent odor and we have a natural disdain for inhaling more. Once he got the first hit (probably small because he would stop inhaling) he wouldn't continue to just keep breathing in the fumes.
Conversely, if he were in an enclosed room with not ventilation and no means of escaping the fumes, then he obviously could have received some lung damage. I have inhaled acid fumes several times and while it is unpleasant, it is typically does not cause permanent damage.
He should still have his lungs checked by a doctor just to make sure and give him some peace of mind though.

I work for a painting contractor, have been for two and a half
weeks. The past two days at our current job some of the guys have
been spraying Muriatic acid on the concrete floors for prep purposes.
They all had respirators on, since I was in other rooms I didn't.
Still quite frequently I could smell the fumes which made it
seriously difficult to breath and in order to finish my job I just
breathed less. Now night #2 my throat all the way down to the bottom
of my lungs hurts, and I'm coughing up excessive phlegm not to
mention my body aches all over.
My advice stay as far away from these fumes as possible!

I KNOW EXACTLY HOW YOU FEEL ABOUT MURIATIC ACID. I WENT TO PUT THIS CHEMICAL INTO OUR SWIMMING POOL AND I WAS EVEN OUTSIDE! I ACCIDENTALLY BREATHED IN SOME OF THE FUMES FROM THE BOTTLE AND I STARTED COUGHING IT WAS AWFUL. NOW TODAY AND EVEN A COUPLE OF DAYS LATER I CAN BARELY SWALLOW BECAUSE MY THROAT IS OBVIOUSLY BURNED FROM THE CHEMICALS. THIS STUFF IS LETHAL AND I FEEL FOR YOUR FATHER.

Hi,
I was cleaning the bathroom and I used some muriatic acid on the
flooring. I accidentally inhaled the fumes but I am sure it is only a
mild exposure since I coughed it out immediately and went out of the
bathroom. And then after a week I discovered I was pregnant. Do you
think this exposure would cause a damage to my baby? I think I was 3
weeks pregnant then. Please advise.
Thanks!

I think the chances of it being harmful to your baby are zero, Karen, but please see a doctor.

It would be good to know how long it takes to experience the corrosive effects of muriatic acid if it seems at first like one has inhaled a mild dose. Would one know immediately that something serious has happened or does the effect of the fumes build on the tissues over time?

Again, see your doctor if you are experiencing any symptoms . . . but I think you'll know it instantaneously if you are exposed to muriatic acid fumes. They are choking and painful.

Three weeks ago I was working in a restaurant when someone poured muriatic acid down the drains. All of a sudden we were engulfed by a rotten egg smell. I got on the microphone and told everyone it would be a good idea if everyone would go outside until we knew what was causing the odor. The owner decided to close, so I went back in to pack up my equipment. 2 days later I woke because I couldn't breathe. I have been to the emergency room twice and was given inhalers and steroids. Since the incident I have felt like someone was sitting on my chest, had a constant headache, lightheadedness and numbness in the mouth, shoulders and neck. The hospital recommended I see a neurologist. Everything I have read about exposure says there will be breathing problems but I have read nothing about my other symptoms. My head has been very unclear since the exposure. Can exposure to muriatic acid harm other parts of the body?

Stephanie, you are hoping a stranger on the internet will tell you NOT to go to a neurologist when you've been to the emergency room twice and the qualified medical doctors who have examined you have recommended it? At the least, see your family physician! It is difficult for a trained physician examining you to tell whether any portion of your symptoms are psychosomatic or neurological, and silly to think that a reader can do so based on the usual toxicology of hydrochloric acid. But a strong rotten egg smell is indicative of exposure to sulfur dioxide rather than hydrochloric acid anyway. Good luck but please see your doctor today.

I inhaled pool chemicals by accident, early this morning. I couldn't breath and coughed-up a lot of phlegm. I drank a lot of milk, water, took a quick shower and laid down for about a hour. It makes you feel quite weak. My breathing is better now. Reading all your e-mail made me wonder if there is any damage. I'm off to the doctor right now.

Muriatic Acid Incident (Scared to Death). I read about a few folks putting muriatic acid in their swimming pools and breathing fumes later. I also had the same problem, but I got into the pool for a couple of hours. I was a little intoxicated since we had a few beers first. I started coughing and noticed that my skin had burns. A couple of days later, I went to the doctor because I thought I was coming down with pneumonia. I was admitted and released later, but I never got rid of the cough and chest irritation. I didn't mention the swimming pool incident to the doctor because I didn't think the symptom was related to something I may have done. Now, after two weeks, I am worried about lung damage. I think if I get another cold it could be fatal. Question; if I do have damage, is there a medicines to help? What does everyone think?

May 20, 2008 This is a subject hard for me to speak of. A cruel human
being broke into my friend's house while we were sleeping in
the living room. This woman kicked down the door and poured
a gallon of hydrochloric (muriatic) acid into the house and
another one all over my friend. We were in a very small
place (350 square feet). I had never heard of this chemical
before, I was wakened up by the strongest, most terrifying,
smell. Lauren Madison
May 20, 2008 Hi, Lauren. Unfortunately, to request a 2nd opinion from a stranger on the internet, with no medical experience, and no real understanding of your exposure, isn't going to work. If you are not satisfied with what you have learned from your visits to the doctor, you need to find a second doctor to examine you and offer his assessment. Good luck. Regards,
I am a crystal miner and we use muriatic acid to clean
iron oxide off the crystals. I have a half face respirator
that I use but I do sometimes get stung in my eyes and feel
the sting on my skin from the vapors coming off of the acid.
We must get pretty close to a large amount of the acid since
we have to insert and remove trays of crystals directly from
the vat of acid. Mike Werner
