Section 2: Composition and Information on Ingredients IngredientCAS NumberPercentACGIH (TWA)OSHA (PEL) Title compound82066-37-3100%0.5mg/m3 (as Cr)0.5mg/m3 (as Cr) Section 3: Hazards Identification May be irritating to eyes, skin and respiratory tract. Chromium (III), a possible metabolite, has acted as a Emergency Overview: tumorigen and mutagen in animal studies. Primary Routes of Exposure:Ingestion, inhalation of dust. Eye Contact:May cause slight to mild irritation of the eyes Skin Contact:May cause slight to mild irritation of the skin. Inhalation:May be irritating to the nose, mucous membranes and respiratory tract. Ingestion:No information on the physiological effects of ingestion of this specific compound. Acute Health Affects:May be irritating to skin, eyes and respiratory tract. It is possible that prolonged exposure could result in formation of Chromium (III) salts in the human body. Chronic Health Affects:Although less toxic than Chromium (VI), some animal studies show Chromium (III) to act as a mutagen and tumorigen. NTP:Yes IARC:No OSHA:No SECTION 4: First Aid Measures Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need Eye Exposure: assistance in keeping their eye lids open. Get immediate medical attention. Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if Skin Exposure: irritation persists. Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty Inhalation: in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce Ingestion: vomiting only if directed by medical personnel.
