What hazard category is HCl?
What hazard category is HCl?
Single Target Organ (STOT): 7647-01-0: The substance or mixture is classified as specific target organ toxicant, single exposure, category 3 with respiratory tract irritation.
What concentration of HCl is dangerous?
Due to its corrosive behavior, the EPA has classified HCl at concentrations of 37% and higher as a toxic substance. Mucous membranes, skin, and eyes are all susceptible to this corrosion.
What are the hazards of acid?
1 Hazards of Acids. Acids are proton donors. They are corrosive to eyes, skin, and mucous membranes. Acid corrosion or burning of tissue is a function of both the pH and the capacity of the particular anions to combine with protein.
Is HCl flammable?
Not flammable or combustible.
How does hydrochloric acid affect the environment?
Hydrogen chloride released into the atmosphere as a gas will undergo wet and dry deposition, and will be readily incorporated into cloud, rain, and fog water. It thus forms a component of acid rain. It also contributes to the processes that cause photochemical smog.
Is hydrochloric acid dangerous to touch?
Hydrochloric acid is a hazardous liquid which must be used with care. The acid itself is corrosive, and concentrated forms release acidic mists that are also dangerous. If the acid or mist come into contact with the skin, eyes, or internal organs, the damage can be irreversible or even fatal in severe cases.
What happens if you smell HCL?
When inhaled, it can result in upper respiratory tract irritation, leading to laryngeal edema, laryngeal spasm, and asphyxia. Concentrated hydrochloric acid causes similar corrosive injuries to exposed tissues and, if ingested, can cause severe corrosive injury to the mouth, throat, esophagus, and stomach.
Is HCL toxic?
Hydrochloric acid is a clear, poisonous liquid. It is a caustic chemical and highly corrosive, which means it immediately causes severe damage to tissues, such as burning, on contact.
Why is hydrochloric acid a hazard?
Is hydrochloric acid a pollutant?
The EPA has identified these facilities as major sources of hazardous air pollutants (HAP) emissions, primarily HCl. Hydrochloric acid is associated with a variety of adverse health effects.
What are the dangers of HCl?
The vapors can irritate and damage the eyes. The EPA reports that chronic occupational exposure to fumes can erode the teeth and result in gastritis, chronic bronchitis, dermatitis and photosensitization. Hydrochloric acid fumes may also aggravate pre-existing eye diseases and skin disorders.
What are the safety precautions for HCL?
Wear a chemical-resistant apron, chemical-resistant gloves and chemical splash goggles at all times when handling HCl to protect your eyes and skin. Concentrated hydrochloric acid is toxic if inhaled, so avoid breathing it in and always handle it while under a fume hood.
What causes high HCl?
If you are under stress, overeat or eat foods that upset your stomach, you may produce excess HCL. Too much HCL can result in acid indigestion, or heartburn, which causes a burning discomfort in your stomach or esophagus. Over-the-counter and prescription antacids contain a base material that neutralizes and counters the effects of stomach acid.
What are the hazards of hydrochloric acid?
SKIN ON CONTACT WITH LIQUID: FROSTBITE. Corrosive.
