Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear rubber gloves, face shield and coveralls. Use a full-body shield to prepare for violent reaction possibility.
Self-contained breathing apparatus (approved mask may be used for short exposures only); rubberized clothing; gloves; shoes; chemical goggles.
Keep material out of water sources and sewers. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors. Neutralize spilled material with crushed limestone, soda ash, or lime. Do not use water on material itself.
May react vigorously or explosively
When heated to decomposition, evolve very toxic fumes of hydrogen chloride and nitrogen oxides.
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use water spray to knock-down vapors.
Pre-addition of nitrogen oxide (or nitrosyl chloride as its precursor) to stoichiometric hydrogen-oxygen mixt @ 240 mbar360 C will cause immediate ignition under variety of circumstances.
Fire will produce irritating, corrosive and/or toxic gases. Vapors from liquefied gas are initially heavier than air and spread along ground. May react violently with water. Containers may explode when heated
Very toxic gases are generated when heated
Abnormal neuropsychologic function has been reported following hydrochloric acid exposure from a leaking tanker truck.
Ingestion of acids may result in burns, gastrointestinal bleeding, gastritis, perforations, dilation, edema, necrosis, vomiting, stenosis, fistula, and duodenal/jejunal injury.
Inhalation may produce dyspnea, pleuritic chest pain, upper airway edema, pulmonary edema, hypoxemia, bronchospasm, pneumonitis, and persistent pulmonary function abnormalities. Airway hyperreactivity has also been reported.
Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite.
Seek medical assistance.
Remove victim to fresh air; call a doctor; enforce complete rest until doctor arrives; observe at least 24 hours for delayed effects.
Remove contaminated clothing, wash exposed area with copious amounts of water. A physician should examine the area if irritation or pain persists.
In case of contact with liquefied gas, thaw frosted parts with lukewarm water Immediately flush skin with running water for at least 20 minutes.
