_________________________________________________________________________________ _________________________________________________________________________________ Product Safety Summary Sheet DuPont™ Hydrochloric Acid ________________________________________________________________________________________ Chemical Identification, Product Identification or Common Name: CAS number: EC number: EC name: Common name: 7647-01-0 231-791-2 Hydrogen chloride Muriatic acid Product Uses and Applications: Hydrochloric acid (HCl) is primarily manufactured from the reaction of chlorine and hydrogen, both of which are prepared by the electrolysis of salt solutions, or isolated as a by-product of many organic or inorganic reactions. Hydrochloric acid is a strong inorganic acid which is used in a wide variety of industries and applications. For example, it is: - produced during the manufacture of various fluorinated gases, - used in some household cleaning products, - used in various other industrial applications. Physical Properties of the Chemical or Product: Hydrochloric acid is commonly used as an aqueous solution of hydrogen chloride in water, while hydrogen chloride (HCl) itself is a colorless, non-flammable and corrosive gas at room temperature. Hydrochloric acid is a highly acidic, corrosive and non-flammable liquid; the typical concentration is in the range of 30 % HCl by weight (commonly called concentrated hydrochloric acid), but solutions of up to 38 % (commonly called fuming hydrochloric acid) and lower concentrations of hydrochloric acid are also available.

However, there is potential for employee exposure during the loading or unloading of transportation vessels or unintended releases or spills. Exposure to hydrochloric acid in these circumstances could result in skin or eye contact with the liquid or the inhalation of the vapor phase. These vapors must be monitored and controlled below the applicable occupational exposure limits(s). Professional and industrial workers should follow the recommended safety measures contained within the (Material) Safety Data Sheet ((M)SDS) and on any product packaging. Employees should be trained in the appropriate work processes and safety equipment to limit exposure to chemical substances. Occupational use of this substance is considered to be safe provided the recommended safety measures in the (M)SDS are followed. Consumer exposure: Consumers can come into contact with the substance through its use as a component of some household cleaners and in some construction applications where hydrogen chloride gas can be released. Consumers need to be aware of the corrosive nature of the substance. Avoid direct contact with skin and eyes. Do not inhale the substance. Consumer products typically contain only small concentration of hydrochloric acid (1-2 %). This use has been assessed as safe, provided that the product is used as directed on the label, following all instructions found on the packaging. Environmental exposure: - As a gas: Hydrogen chloride release into the environment does not normally occur since the gas is used only by industry within closed systems under controlled conditions. - As a liquid: Hydrochloric acid lowers the pH of any water into which it is released. Industrial waste-water containing hydrochloric acid is neutralized by the addition of a basic (alkaline) substance to render it a neutral solution which can be safely disposed. If a large amount of hydrochloric acid is released or if other acids are present, the pH could be lowered until it is harmful for aquatic animals and plants (at pH 3 to 5). As this is a generic pH effect and is not a substance unique effect of hydrochloric acid, it is not classified as toxic to the aquatic environment. DuPont™ Hydrochloric Acid Page 2 of 4 Revised September 14, 2012 - As a diluted liquid: Small-scale release into drains from household cleaning products poses negligible risk to the environment due to the large dilution of the acid and neutralization by the buffering capacity of the system or natural waters. Health Information: Note: The information contained in this section may be useful to someone handling the non formulated, undiluted substance such as a manufacturer or transporter. Consumers are not likely to come in contact with the undiluted substance. Hydrochloric acid exists naturally as a major component of gastric acid, maintaining a pH of 1-2 in the stomach. For more information on health hazards and recommended protective equipment, please refer to the (M)SDS. Exposures may affect human health as follows: Effect Assessment Acute Toxicity Result Inhalation: May cause respiratory irritation. In serious cases, can lead to pulmonary edema and death (from Eurochlor website). Irritation Causes severe skin burns. May be corrosive. Causes eye burns. May be corrosive. Sensitization Based on available data, not sensitizing. Mutagenicity Based on available data, not classified. Carcinogenicity Based on available data, not considered carcinogenic. Toxicity after repeated exposure Effects from repeated exposure may cause altered lung function or difficulty breathing. Toxicity for reproduction Based on available data, not classified as a reproductive or developmental toxicant. Environmental Information: Note: The information in this chapter is intended to provide brief and general information of this substance’s environmental impact. The results in the table below refer to testing performed with the non formulated, undiluted substance. The data do not replace the data given in the (M)SDS. For more information and recommended protective measures please refer to the (M)SDS. Effect Assessment Aquatic Toxicity Persistence and degradability Bioaccumulation potential Result Not toxic to aquatic life, however decreasing the pH in waterways can lead to adverse effects. As the substance is inorganic, it is regarded as not biologically degradable or persistent. Not expected to bioaccumulate. Risk Management Workplace Management: Risk management measures for industrial site use include containment through engineering controls and personal protective equipment. Use appropriate respiratory protection since there is the opportunity for exposure to anhydrous Hydrochloric Acid. DuPont™ Hydrochloric Acid Page 3 of 4 Revised September 14, 2012 Uses advised against are those that may lead to aerosol formation (mists), which could be harmful for the eyes, skin and respiratory system. Workers should follow the recommended safety measures contained within the (Material) Safety Data Sheet ((M)SDS) and on any product packaging. Employees should be trained in the appropriate work processes and safety equipment to limit unnecessary exposure to chemical substances. Occupational use of this substance is considered to be safe provided the recommended safety measures in the (M)SDS are followed. Consumer Risk Management: For end-use products containing Hydrochloric acid, such as household cleaners, consumers should always follow manufacturer's instructions for the safe handling of the product. Always read and follow the instructions given in the product labels prior to use.
