EMERGENCY OVERVIEW** DANGER Flammable. Irritating to eyes and skin. Harmful by inhalation, in contact with skin and if swallowed. Contains ethylene glycol monobutyl ether (butoxyethanol). Prolonged and/or repeated exposure through inhalation or extensive skin contact with EGBE may result in damage to the blood and kidneys. This product contains ethylbenzene. The International Agency for Research on Cancer (IARC) has evaluated ethylbenzene and determined it to be possibly carcinogenic to humans (Group 2B, based on sufficient evidence in experimental animals and inadequate evidence in humans). Keep away from heat. Keep away from sources of ignition - No smoking. Keep container tightly closed. Do not get in eyes, on skin or on clothing. Do not take internally. Use with adequate ventilation. Avoid breathing vapor. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. After contact with skin, wash immediately with plenty of water. Use a mild soap if available. Wear suitable protective clothing and gloves. Flammable Liquid; may release vapors that form flammable mixtures at or above the flash point. Vapors can travel to a source of ignition and flash back. Empty product containers may contain product residue. Do not pressurize, cut, heat, weld, or expose containers to flame or other sources of ignition. May evolve oxides of carbon (COx) under fire conditions.

Health hazards

ACUTE EYE CONTACT : Can cause moderate to severe irritation. SKIN CONTACT : Can cause moderate irritation. Can be absorbed through the skin. Repeated or prolonged exposure may cause skin irritation and rash (dermatitis). INGESTION : Not a likely route of exposure. May cause nausea and vomiting. Can cause chemical pneumonia if aspirated into lungs following ingestion. Can cause central nervous system depression. Large quantities may cause kidney and liver damage. Ingestion of an ingredient in the controlled product has caused ocular effects in laboratory animals. Ingestion of an ingredient in the controlled product has caused damage to the lungs in laboratory animals. INHALATION : Repeated or prolonged exposure may irritate the respiratory tract. Product mist or vapors may cause headache, nausea, vomiting, drowsiness, stupor or unconsciousness. Prolonged inhalation of vapors and/or mists may be harmful. Can cause central nervous system depression. SYMPTOMS OF EXPOSURE : Acute : Excessive exposure may cause central nervous system effects, nausea, vomiting, anesthetic or narcotic effects. Chronic : Frequent or prolonged contact with product may defat and dry the skin, leading to discomfort and dermatitis. Repeated or excessive exposure to butoxyethanol may cause injury to red blood cells (hemolysis), kidney or the liver. AGGRAVATION OF EXISTING CONDITIONS : Skin contact may aggravate an existing dermatitis condition. EMERGENCY TELEPHONE NUMBER(S) (800)463-3216 (24 Hours) CHRONIC This product contains ethylbenzene.
