Note: See Section 16 for the full text of the R-phrases above. Hazards Identification Preparation Hazards and Toxic by inhalation, in contact with skin and if swallowed. Causes burns. Classification: USA: This material is considered hazardous by the OHSA hazard Communication Standard (29 CFR 1910.1200). Canada: This is a controlled product under WHMIS. European Communities (EC): This preparation is classified as dangerous according to Directive 1999/45/EC. Classifications: Toxic and Corrosive. Hazards Identification, continued Appearance, Color and Odor: White paste, odorless Primary Route(s) of Exposure: Inhalation, Eye contact, Skin contact, Ingestion. Exposure may be from contact to product as packaged and from particulates generated during use. Potential Health Effects: ACUTE (short term): see Section 8 for exposure controls Inhalation: Inhalation of particulates from the flux can be moderately to severely irritating to the nose, throat and respiratory system. Symptoms of over-exposure include coughing, sneezing and difficulty breathing. Extreme over-exposure by inhalation to particulates may cause toxic effects similar to those described for Ingestion. Ingestion: Toxic if swallowed. May cause nausea, vomiting and diarrhea. Ingestion may result in damage to the tissues of the gastrointestinal system and systemic fluoride toxicity, which may be fatal. Symptoms of acute toxicity may include excitement or depression; lethargy; seizures; coma; dehydration; kidney failure; arrhythmias; shock; cyanosis; low blood pressure; and metabolic acidosis. Skin: Severely irritating or corrosive to the skin. Causes burns with direct contact. Thermal decomposition of this product may result in the release of hydrogen fluoride. This substance may be absorbed through the skin, causing burns. Extreme over-exposure to hydrogen fluoride can be fatal through systemic fluoride poisoning. Eye: Product is irritating to the eyes. Causes eye burns with direct eye contact. CHRONIC (long term): see Section 11 for additional toxicological data Prolonged or repeated over-exposure by skin contact may cause dermatitis. Long-term over-exposure to fluorides can cause a deposit of fluorides in the bones and teeth, a condition called Fluorosis. This may cause pain, disability and mottling of the teeth. Fluorides can irritate the lungs and may cause bronchitis to develop with cough, phlegm and/or shortness of breath. Long-term over-exposures to inorganic borate compounds by inhalation or ingestion may impair fertility and may cause harm to the unborn child. Medical Conditions May aggravate an existing dermatitis.
