Hill Brothers Chemical Company-Sodium Hydroxide 50% Liquid http://www.h i 116~rothers.com/msds/sh501 iqd. htm Skin: Contact of the skin may cause skin irritation and, with greater expos. severe bums with scarring. Eyes: Sodium hydroxide is destructive to eye tissues on contact. Will cause severe burars that result in damage to the eyes and even blindness. Contact lenses should not be worn when working with this . chemical. Carcinogenicity Lists: NoNTP: IARC Monograph: NoOSHA Regulated: Yes Summary of Chronic Health Hazards: The chronic local effect may consist of multiple areas of superficial destruction of the skin or of primary irritant dermatitis. Similarly, inhalation of dust, spray, or mist may result in varying degrees of irritation or damage to the respiratory tract tissues and an increased susceptibility to respiratory illness. Signs and Symptoms of Exposure: A physician should be contacted if anyone develops any signs or symptoms and suspects that they aze caused by exposure to sodium hydroxide. Effects of Overexposure: Sodium hydroxide is a strong alkali and is corrosive to any tissue with which it comes in contact. Emergency and First Aid Procedures: Ingestion: Do Not Induce Vomiting. If the person is conscious, give him large quantities of water immediately to dilute the sodium hydroxide. Do not attempt to make the exposed person vomit. GET MEDICAL ATTENTION IMMEDIATELY. Inhalation: Move the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. If breathing is difficult, give oxygen. Keep the affected person warm and at rest. GET MEDICAL ATTENTION IMMEDIATELY. Skin: Immediately flush contaminated skin with water. If lazge areas of the body are contaminated or if clothing is penetrated, immediately use safety shower, removing clothing while under the shower. Flush exposed azeas with large amounts of water for at least 15 minutes. GET MEDICAL ATTENTION IMMEDIATELY. Wash clothing before reuse. Eyes: Immediately flush eyes with a directed stream of water for at least 15 minutes. Forcibly hold eyelids apart to ensure complete irrigation of all eye and lid tissue. Washing eyes within 1 minute is essential to achieve maximum effectiveness. GET MEDICAL ATTENTION IMMEDIATELY. Contact lenses should not be worn when working with this chemical. Medical Conditions Generally Aggravated by Exposure: Sodium hydroxide is a respiratory irritant. • Persons with impaired pulmonary function may be at increased risk from exposure, and should have limited exposure to this material. Section VII -Precautions For Safe Handling And Use Steps To Be Taken In Case Material Is Released Or Spilled: Leaks should be stopped. Spills should be contained and cleaned up immediately. Spills should be removed by using a vacuum truck. Neutralize remaining traces of material wrth any dilute inorganic acid sucfi as hydrochlonc, sulfuric, nitric, phosphoric, or acetic acid. The spill area should then be flushed with water, followed by liberal covering of sodium bicarbonate. All clean-up material should be removed and placed in approved containers, labeled and stored in a safe place to await proper treatment or disposal. Spills on azeas other than pavement (dirt or sand) may be handled by removing the affected soils and placing in approved containers. Persons not wearing protective equipment and clothing should be restricted from azeas of spills until cleanup has been completed. Handling and Storing Precautions: Prevent possible eye and skin contact by wearing protective clothing and equipment. Storage tanks must be vented and diked. Store drums of sodium hydroxide separate from acids, metals and explosives. Provide adequate drainage. When diluting, use agitation and add concentrated sodium hydroxide to water at a controlled rate to control heat of dilutran and to avoid splattering. Do not add water to sodium hydroxide. Waste Disposal Methods: Dispose in approved chemical disposal area or in a manner which complies with all local, state and federal regulations. Do not flush to sewer. Other Precautions: Sodium hydroxide reacts with reducing sugars such as fructose, lactose, maltose, galactose, lewlose, and arabinose to form carbon monoxide. While the potential for worker exposure to • carbon monoxide may be small, a potential does exist during cleaning of certain dairy and possrbly other industry equipment. Carbon monoxide gas can form upon contact with food and beverage products rn 3 of5 (0/14/99 1:35 PM
