FIRST AID MEASURESI ngestion:Do not induce vomiting. If victim is conscious, rinse mouth, give water. Never give anything by mouth to an unconscious person. Seek immediate medical Contact:Immediately remove contaminated clothing. Flush skin with water for at least 15 minutes. Seek immediate medical Contact:Immediately flush eyes with large amounts of water, holding lids apart to ensure rinsing of entire surface.

2 Continue rinsing for at least 15 minutes. Remove contact lenses, if present and easy to do. Washing eyes within several seconds of contact is essential to achieve maximum effectiveness. Get immediate medical :Remove person to fresh air and keep comfortable for breathing. If not breathing, give artificial respiration. If breathing is difficult administer oxygen. Seek medical attention. 2.

4 FIRE-FIGHTING MEASURESE xtinguishing Media:Material is not flammable. Use extinguishing media suitable to surrounding Equipment and Precautions:Use water to cool nearby containers and structures. Wear full protective equipment, including suitable respiratory corrosive, toxic fumes during a Hazards:Reacts with most metals to produce flammable hydrogen corrosive, toxic fumes during a combustion products:Toxic fumes of hydrogen chloride, hydrogen, chlorine6. ACCIDENTAL RELEASE MEASURESS pill Procedures:Prevent spread of spill. Wear full protective equipment, including a complete protective suit and an appropriate respirator depending upon the size of the spill. Carefully neutralize with soda ash or lime. Place material into clean disposal container. Flush spill area with notes:Symptoms and effects include irritation and burns, cough, choking, pulmonary edema7. HANDLING AND STORAGES torage and Handling:Store locked up in a cool, dry, well-ventilated corrosive materials storage area away from incompatible materials.

5 Keep containers tightly closed and protect them from physical damage. Minimize exposure to air and with strong bases. Most common metals, water, amines, metal oxides, acetic anhydride, poropiolactone, vinyl acetate, mercuric sulfate, calcium phosphide, formaldehyde, alkalies, sulfuric acid , chlorosulfonic Materials:Do not breathe dusts or thoroughly after only outdoors or in a well-ventilated protective gloves, protective clothing, eye protection, face STABILITY AND REACTIVITYS tability:StableIncompatibles:Incompatibl e with strong bases. Most common metals, water, amines, metal oxides, acetic anhydride, poropiolactone, vinyl acetate, mercuric sulfate, calcium phosphide, formaldehyde, alkalies, sulfuric acid , chlorosulfonic to Avoid:Excessive heat. :No information availablePossibility of Hazardous Reactions:Hazardous polymerization will not occur8. EXPOSURE CONTROLS AND PERSONAL PROTECTIONE ngineering Controls:Use general or local exhaust ventilation to meet TLV and PEL Protection:Respiratory protection required if airborne concentrations exceed PEL or TLV.

6 Use a NIOSH approved chemical cartridge respirator with an organic vapor/ acid gas cartridge. At exposures above 100 ppm the use of a supplied air respirator or SCBA is Protective Equipment: SAFETY goggles, face shield, chemical-resistant gloves and protective clothing appropriate for the risk of exposure. Neoprene gloves are recommended. Facilities storing or utilizing this material should have readily accessible eyewash stations and SAFETY showers. Select respirators and other SAFETY equipment in accordance with regulations and based upon the particular conditions of use and risk of exposure. Always use safe chemical-handling and good industrial hygiene & ACGIH Exposure Limits:WaterNone identifiedHydrochloric acidOSHA Ceiling: 5 ppm; 7 mg/m3 ACGIH Ceiling: 2 ppm; 3 mg/m3 OSHA SDS #: 25723 rev 101 3/27/2015 HYDROCHLORIC acid , 37%Page 216.
