MSDS OF HYDROCHLORIC ACID SOLUTION

MATERIALS SAFETY DATA SHEET OF HYDROCHLORIC ACID SOLUTION

Chemical name	Hydrochloric Acid
Synonyms	Hydrogen Chloride, Muriatic Acid
Molecular mass	36.5 gm/mol
CAS no.	7647-01-0
Physical appearance	Colourless compressed liquefied gas with pungent odour
Physical dangers	The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen
Chemical dangers	The solution in water is a strong acid. It reacts violently with bases and is corrosive. Reacts violently with oxidants. This produces toxic gas (Chlorine). Attacks many metals in the presence of water. This produces flammable/explosive gas (Hydrogen).
Boiling point	-85⁰C
Melting point	-114.2⁰C
Specific gravity	36 % Concentrated hydrochloric acid has specific gravity 1.18 gm /cc
Chemical formula	HCL
Flammability	NO
Solubility in water	g/100ml at 30°C: 67 (moderate)
UN no.	1789
Storage	Cool, fireproof if in building. Separated from food and feedstuffs and incompatible materials. See chemical dangers. Keep in a well-ventilated room.
Inhalation risk	A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
Effects of short-term exposure	Rapid evaporation of the liquid may cause frostbite. The substance is corrosive to the eyes, skin and respiratory tract. Inhalation of this gas may cause asthma-like reactions (RADS). Exposure could cause asphyxiation due to swelling in the throat. Inhalation of high concentrations may cause lung oedema, but only after initial corrosive effects on the eyes and the upper respiratory tract have become manifest. Inhalation of high concentrations may cause pneumonitis.
Effects of long-term or repeated exposure	Repeated or prolonged inhalation may cause effects on the teeth. This may result in tooth erosion. The substance may have effects on the upper respiratory tract and lungs. This may result in chronic inflammation of the respiratory tract and reduced lung function. Mists of this strong inorganic acid are carcinogenic to humans.

AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!

	Symptoms	Prevention	First aid
Inhalation	Cough. Sore throat. Burning sensation. Shortness of breath. Laboured breathing.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.
Skin	Redness. Pain. Serious skin burns. ON CONTACT WITH LIQUID: FROSTBITE.	Cold-insulating gloves. Protective clothing.	Wear protective gloves when administering first aid. First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer immediately for medical attention.
Eyes	Redness. Pain. Blurred vision. Severe burns. ON CONTACT WITH LIQUID: FROSTBITE.	Wear face shield or eye protection in combination with breathing protection.	Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
