                First Aid Measures

                Ingestion
                Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
                Inhalation
                Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth respiration.
                Skin
                Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
                Eyes
                Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation is required (at least 30 minutes).

                Handling and Storage

                Storage
                Keep container closed when not in use. Corrosives area. Store protected from moisture.
                Handling
                Keep container tightly closed. Do not get on skin or in eyes. Do not ingest or inhale. Use with adequate ventilation. Do not allow contact with water. Discard contaminated shoes. Keep from contact with moist air and steam.

                Hazards Identification

                Inhalation
                May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema. Causes chemical burns to the respiratory tract.
                Skin
                Causes skin burns.
                Eyes
                Contact with eyes may cause severe irritation, and possible eye burns.
                Ingestion
                May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns.
                Hazards
                Containers may rupture. Hot liquid is spontaneously flammable because of presence of dissolved phosphorus.

                Exposure Controls/Personal Protection

                Personal Protection
                Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.
                Respirators
                A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
                Exposure Effects
                Abnormal neuropsychologic function has been reported following hydrochloric acid exposure from a leaking tanker truck.

                Autoignition
                159
                Fire Fighting
                Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Containers may explode when heated. Extinguishing media: Use foam, dry chemical, or carbon dioxide. If water is the only media available, use in flooding amounts. Do NOT get water inside containers. Cool containers with flooding quantities of water until well after fire is out.
                Fire Potential
                Flammable.

                Accidental Release Measures

                Small spills/leaks
                Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Provide ventilation. Do not get water inside containers.
