Question

my apt complex used the chemical and i wanted to know if i should stay somewhere else with my dog b/c of the fumes. thanks

Answer 1

Muriatic acid andf hydrochloric acid is the same.

You should look up The Material safety data sheet for the chemical, some information is included below

Hazards Identification
Emergency Overview
--------------------------
POISON! DANGER! CORROSIVE. LIQUID AND MIST CAUSE SEVERE BURNS TO ALL BODY TISSUE. MAY BE FATAL IF SWALLOWED OR INHALED. INHALATION MAY CAUSE LUNG DAMAGE.

SAF-T-DATA(tm) Ratings (Provided here for your convenience)
-----------------------------------------------------------------------------------------------------------
Health Rating: 3 - Severe (Poison)
Flammability Rating: 0 - None
Reactivity Rating: 2 - Moderate
Contact Rating: 4 - Extreme (Corrosive)
Lab Protective Equip: GOGGLES & SHIELD; LAB COAT & APRON; VENT HOOD; PROPER GLOVES

Potential Health Effects
----------------------------------

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.
Ingestion:
Corrosive! Swallowing hydrochloric acid can cause immediate pain and burns of the mouth, throat, esophagus and gastrointestinal tract. May cause nausea, vomiting, and diarrhea. Swallowing may be fatal.
Skin Contact:
Corrosive! Can cause redness, pain, and severe skin burns. Concentrated solutions cause deep ulcers and discolor skin.
Eye Contact:
Corrosive! Vapors are irritating and may cause damage to the eyes. Contact may cause severe burns and permanent eye damage.
Chronic Exposure:
Long-term exposure to concentrated vapors may cause erosion of teeth. Long term exposures seldom occur due to the corrosive properties of the acid.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye disease may be more susceptible to the effects of this substance.

First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately.
Ingestion:
DO NOT INDUCE VOMITING! Give large quantities of water or milk if available. Never give anything by mouth to an unconscious person. Get medical attention immediately.
Skin Contact:
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.

In theory, mixing the alkaline bleach with the acid should achieve a neutral pH. What happens in practice is a whole other ballgame. The common household bleach you know as Chlorox is not 100% chlorine, it's actually a much weaker solution, about 5%. The balance is water. Now as every first year chemical student knows, you can add acid to water, but it's a dangerous thing to add water to acid. However, you still have to contend with that chlorine, and that's where the danger is. The reaction is thermal and explosive, and gives off dangerous gases. You will have a high risk of asphyxiating yourself, and at the very least will come away with chemical burns inside and out. There are very few uses for muriatic acid, limited mostly to cleaning concrete and masonary work, and even then there are other products much less corosive and dangerous to work with. The acid alone gives off enough dangerous fumes, and the liquid is highly corrosive and toxic to everything around it. It is hydrochloric acid, by any other name, and should not be treated carelessly. The most common methods of neutralizing it after use is with applications of lime or baking soda- most prefering lime as it comes in bigger bags and is sold at the same places you buy the acid. As they are dry powder products, there is no danger of a water-acid reaction or explosion. What usually happens in the case of amateurs mixing these chemicals is that the person either dies, or wakes up in ICU with severe burns to the lungs and upper respiratory tract, on a ventilator and with a tracheotomy in place. Not a pretty picture, I assure you. These are not chemicals to play with.

Answer 6

First question that would come to mind is "How well ventilated is the building you live in". Have proper precautions been put into place to insure the safety of the residents. But if you feel better going somewhere else to live for the time being then do it.

Answer 7

Harmless unless you breath them, but in all seriousness they can burn your lungs and skin if the fumes are strong enough..
if there just cleaning the masonary work on the outside of your building it should be alright but keep the windows closed..

Answer 8

Definitely stay away. If you can smell it then there're too much fumes. If it's in an enclosed place (which they would have had to be pretty stupid to use it in) open some windows and doors and turn on a fan. If it's outside it should go away by itself within a day or two. HCl can burn your lungs, your eyes, and your skin.

Answer 9

If you notice even the slightest discomfort in your lungs I would stay away...I use both in cleaning my pool from time to time...you don't want to get a whiff of them.
