What is MSDS of HCl?
Inhalation: Vapors and mist will irritate throat and respiratory system and cause coughing. Skin contact: Causes skin burns. Eye contact: Causes eye burns. Ingestion: Harmful if swallowed.
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.
Is HCl a hazardous substance?
Hydrochloric acid is corrosive to the eyes, skin, and mucous membranes. Acute (short-term) inhalation exposure may cause eye, nose, and respiratory tract irritation and inflammation and pulmonary edema in humans.
Is HCl corrosive to metal?
Similarly, dry hydrogen chloride (HCl) is not corrosive to most metals. Once it is dissolved in water hydrochloric acid is formed and this is corrosive to many metals and alloys. Materials considered include steels, stainless steels, nickel-base alloys, copper-base alloys, titanium, zirconium and tantalum.
What is hydrochloric acid used for?
Abstract. Hydrochloric acid (HCl) is commonly used for the neutralization of alkaline agents, as a bleaching agent, in food, textile, metal, and rubber industries. It is neutralized if released into the soil and it rapidly hydrolyzes when exposed to water.
Why is hydrochloric acid a hazard?
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.
How do you handle 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.
Is HCl biodegradable?
Persistence and degradability: Not biodegradable. Hydrochloric acid will likely be neutralized to chloride by alkalinity present in natural environment..
What is a safe concentration of HCl?
OSHA: The legal airborne permissible exposure limit (PEL) is 5 ppm, not to be exceeded at any time. NIOSH: The recommended airborne exposure limit (REL) is 5 ppm, which should not be exceeded at any time. ACGIH: The threshold limit value (TLV) is 2 ppm, which should not be exceeded at any time.
What happens if you breathe hydrochloric acid?
Hydrogen chloride gas can irritate the lungs, causing a cough and shortness of breath. Breathing high levels of the gas or vapor can lead to a build-up of fluid in the lungs, which may cause death. Because hydrochloric acid is corrosive, it can cause eye damage, even blindness, if splashed in the eyes.
What materials can withstand hydrochloric acid?
Nonmetallic materials are generally preferred for handling and storing HCl. Plastics, such as polyethylene, polypropylene, polyvinyl chloride are resistant, but are limited to ambient temperatures. Fiberglass-reinforced plastic (FRP) is also resistant and has been generally used for the storage and transportation.
Will hydrochloric acid eat stainless steel?
The common stainless steel types, 304 and 316 should be considered non-resistant to hydrochloric acid at any concentration and temperature. Any additional chlorides or chlorine in the acid can be expected to make attack more severe.
