<br />I Trade Name: <br /> <br />.. <br /> <br />HYDROCHLORIC ACID <br /> <br />Page 2 of 3 I <br /> <br />SECTION fi - HEALTH HAZARD DATA. <br /> <br />THRESHOLD LIMIT VALUE: 5 PPM - CeiIilg limit (ACGIH) <br />EFFECTS OF OVEREXPOSURE <br /> <br />Acute Inhalation: Inhalation of fumes at lower IewIs may cause irritation and burning of the throat, CXlIJQhing and choking. M higher <br />levels (allow 50 PPM), inftammalion of the nose, throat or larynx, bronchitis, pneumonia, and headache may occur. <br />Severe cases may exhibit necrosis of the windpipe and bronchial epiIheIium, damage to pulmonary blood vessels <br />and emphysema. <br /> <br />Chronic Inhalation: Repealed or prolonged overexposure may cause erosion and discoloration of exposed teelh, chronic bronchitis and <br />gastritis. <br /> <br />Acute Eye Conlact Contact may cause severe irritation, conjundMtis, corneal necrosis and bums. <br /> <br />Chronic Eye Contact: Coojundivitis or effects sirlJ& to those for acute exposure may occur. <br /> <br />Acute Skin Contact: Conlacl may cause severe iniIation, inlammation, ulceration, necrosis and chemical bums. <br /> <br />Chronic Skin Contact: Repeated or prolonged contact may cause chrooic inilation and delmatitis. Photosensitization may also occur. <br /> <br />Acute Ingestion: Ingestion may cause bums of the mouth, throat, esophagus and sIDmach with pain, nausea, salivation, vomiting, <br />diarrhea, chiIs, shock and intense Ihirst Nephritis, fever and perforation of the intestinal IIacI, and cirCulatory <br />coUapse may occur. <br /> <br />Carcinogenicity: This product is not listed as a carcinogen by NTP, IARC or OSHA. <br /> <br />Medical Conditions Aggravated by Exposure: IndMduals with pre-exisling diseases of the lungs may have inaeased susceptibility to the toxicity of excessive <br />exposures. <br /> <br />SECTION 7 - REACTMTY DATA <br /> <br />Stability: <br />Conditions to Avoid: <br />Incompatibility (Materials to Avoid): <br />Hazardous Dealmposilion Products: <br /> <br />Hazardous Polymerization: <br /> <br />Stable <br />Avoid contact with melals and stong oxidizers. <br />Avoid base and corrosive materials. <br />Flammable hydrogen gas can be produced by reaction with most metals and may form explosive mixtures with air. <br />Chlorine gas will be released by mixing wiIh stong oxidizers. <br />WiD notocwr. <br /> <br />SECTION 8 -SPILLOR LEAK PROCEDURES <br /> <br />Steps to be taken in case material is spilled or released: Evacuate area and deny entry by unauthorized peISOIlnel. Do not breathe vapors, stay upwind. For <br />large spills, contain and pump into tanks, which have been constructed for Hydrochloric Acid service. Full acid resistant suits and seIf-rontained breathing <br />apparatus should be worn during emergency operations. Knock down vapors with water spray or water fog. Water used to knock down vapors may become <br />corrosive and should be contained properly for later disposal. Neu1ralize spilt with slaked lime, sodium bicarbonate or aushed limestone. Since neutralization <br />generates heat (exothermic reaction), the reaction can be violent The acid should be diluted and cooled before attempting to neutralize. Spills must be <br />neutralized and federal. stale and local regulations must be consulted before lIushing to sewer. For small spills, take up wiIh sand or other absorbent material <br />and react with dry alkali (soda ash or lime). Place into containers for IaIer disposal. Adhere to federal, stale and local regulations on reporting releases. <br /> <br />Waste disposal method: Landfill or neutralize in accordance with federal, state and local environmental regulations. <br /> <br />SECTION9..SAFEHANDUNG AND USE INFORMATION <br /> <br />Respiratory Protection: <br /> <br />Use NIOSHIMSHA approved IJCid.gas respi'ator for aeas where airborne exposure is excessive. Do not exceed <br />the working limits of the respi'ator. <br /> <br />Provide good general room venlilation to keep workroom concentration below current applicable OSHA safety and <br />heaIIh requi'ements (Section 2). Use local exhaust ventilation at points of vapor emission. <br /> <br />Wear protective gloves, such as rubber or neoprene, to minimize ski1 contact. <br /> <br />Chemical safety goggJes and a ruB faceshieId to prevent conIacl <br /> <br />Eye wash faciIty should be in close proximity. Use of rubberized coveraUs, rubber shoes. and emergency shower <br />avalability are recommended. <br /> <br />Ventilalion: <br /> <br />Proleclive Gloves: <br /> <br />Eye Protection: <br />Other Protective Equipment <br />
