Box 1239 Spring, TX * (281) * 1 (800) PRODUCT IDENTIFICATION Material Safety Data Sheet Product Name: Synonyms: Distributed By: Telephone: Fax: Hydrochloric Acid (All Grades) Muriatic Acid, HCl Solution, Aqueous Hydrgogen Chloride NAPCO Chemical Company, Inc. P.O. Box 1239 Spring, TX (281) (281) Emergency Contact: Physical Description: CHEMTREC (24 Hrs) at 1 (800) United States, Canada, Puerto Rico, and Virgin Islands Colorless liquid with a pungent odor 2. PRODUCT INGREDIENTS Exposure Limit Components Percent (%) OSHA PEL: ACGIH TLV: Hydrogen Chloride mg / m 3 (5 ppm) 2 ppm Water Not Applicable Not Applicable HAZARD IDENTIFICATION Emergency Overview: DANGER! Causes severe burns to the lungs, skin, eyes and gastrointestinal. Causes permanent eye damage. May be harmful or fatal if swallowed. Contact with metals may evolve flammable hydrogen gas.

2 4. FIRST AID MEASURES Eye Contact: Skin Contact: Inhalation: Ingestion: Other Instructions: Immediately flush eyes with water for at least 15 minutes. Hold eyelids open to ensure adequate flushing. Get immediate medical attention. Remove contaminated clothing and shoes. Wash affected skin area with soap and water. Delayed skin damage is possible if product is not completely washed off. Get immediate medical attention. Remove to fresh air. Get immediate medical attention. If ingested, dilute swallowed material by drinking water. DO NOT INDUCE VOMITING. Never give anything by mouth to an unconscious person. Get immediate medical attention. The absense of visible signs or symptoms of burns does NOT exclude the presence of actual tissue damage. Probable mucosal damage may contraindicate the use of gastric lavage. 5. FIRE-FIGHTING MEASURES Flash Point: Auto ignition Temperature: Flammable Limits, in Air: LEL (%) UEL (%) Extinguishing Media: Special Fire Fighting Procedure: Unusual Fire and Explosion Hazards: Hazardous Combustion Products: Not Flammable Not applicable Not data available Not data available Dry chemical, foam, water spray, or carbon dioxide In the event of a fire, wear NIOSH approved, positive pressure, self-contained breathing apparatus (SCBA) and full protective clothing. Evacuate all non-essential personnel from the danger area. May spatter or generate heat when mixed with water. Contact with metals may evolove flammable hydrogen gas. Thermal decomposition products or combustion products include hydrogen chloride. 6. ACCIDENTAL RELEASE MEASURES Personal Precautions: Environmental Precautions: Restrict access to keep out unauthorized or unprotected personnel. Stay upwind of spilled material. Wear appropriate PPE during all cleanup activities. Avoid inhalation and direct contact. Keep spilled material away from sewage/drainage systems and waterways. This product contains a U.S. EPA Reportable Quantity (RQ) substance. If amounts exceeding the Reportable Quantity are released, notification of the National Response Center is required (800) See section 15.

3 Methods for clean-up: All cleanup personnel must be properly trained. Confine the spill and remove incompatible materials and ignition sources. Ensure adequate ventilation. Secure the source of the leak if conditions are safe. Neutralize spill with soda ash or dilute caustic soda. Collect with an appropriate absorbent material such as clay or vermiculite. Place waste in an appropriate container for disposal. Use care during cleanup to avoid exposure to the material and injury from broken containers. Keep out of water supplies and sewers. Releases should be reported to local authorities if required. 7. HANDLING AND STORAGE Handling: Storage: An industrial hygiene risk assessment is required to determine the appropriate respiratory protection. A NIOSH approved full-face, air- purifying cartridge respirator may be appropriate under limited exposure conditions. Wear an approved supplied air respirator if there is a potential for an uncontrolled release, exposure levels are not known, or in other circumstances where air-purifying respirators may not provide adequate protection. Avoid breathing vapor or mist. Do not get in eyes, on skin, or on clothing. Wash thoroughly after handling. When mixing, slowly add to water to minimize heat generation and spattering. Store and handle in accordance with all current regulations and standards. Store in rubber-lined steel, acid-resistant plastic or glass containers. Keep container tightly closed and properly labeled. Do not store in aluminum containers or use aluminum fittings. Keep away from incompatible materials. 8. EXPOSURE CONTROLS & PERSONAL PROTECTION Eye Protection: Skin Protection: Respiratory Protection: Engineering Controls: Required Work/ Hygiene Procedure: Wear chemical splash goggles or face shield. Minimize contact with product. Wear chemical resistant coveralls, boots, gloves, apron and/or suitable long sleeve clothing. Consult PPE manufacturer for chemical resistance information. Ensure adequate ventilation. Use closed system when possible. Provide local exhaust where vapor or mist may be generated. Emergency eyewash and safety shower facilities should be available in the immediate work area. Wash hands thoroughly after handling. Do not eat, drink or smoke in work area. If unusual exposures are expected, an industrial hygiene review of work practices, engineering controls and PPE is recommended.

STABILITY AND REACTIVITY Stability: Conditions to Avoid: Hazardous Decomposition: Hazardous Polymerization: Stable under normal temperatures and pressure. Avoid heat, flames, sparks, and other sources of ignition. Contact with water may produce a strong exothermic reaction with spattering. Contact with metals may evolve flammable hydrogen gas. Hydrogen Chloride may react with cyanide, forming lethal concentrations of hydrocyanic acid. Thermal decomposition products or combustion biproducts include Hydrogen chloride. Not expected to occur. 11. TOXICOLOGY INFORMATION Primary Exposure: Potential Health Effects: Eye Contact: Skin Contact: Inhalation: Ingestion: Carcinogenicity: Medical Concerns: Eye, skin contact, inhalation Causes severe eye damage Causes skin burns. Onset of symptoms may be delayed following exposure. Corrosive to respiratory tract. May be Harmful if swallowed. Ingestion may cause chemical burns, pain, vomiting, difficulty breathing and other gastrointestinal effects. The components of this product are not classified as carcinogenic by OSHA, NTP, or IARC. Asthma and other respiratory conditions and skin disorders may be aggravated by overexposure.
