Harmful by inhalation, in contact with skin and if swallowed. Emergency Overview: Chromium (III), a possible metabolite, has acted as a tumorigen and mutagen in animal studies. Primary Routes of Exposure:Ingestion, inhalation of dust Eye Contact:Causes slight to mild irritation of the eyes Skin Contact:Causes slight to mild irritation of the skin. Harmful in contact with skin. Inhalation:Irritating to the nose, mucous membranes and respiratory tract. Harmful through inhalation. Ingestion:Harmful if swallowed. Acute Health Affects:Irritating to skin, eyes and respiratory tract. Harmful through inhalation, in contact with skin and if swallowed. 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. SECTION 5: Fire Fighting Measures Flash Point:none Autoignition Temperature:none Explosion Limits:none Extinguishing Medium:carbon dioxide, foam or dry powder If this product is involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure Special Fire Fighting Procedures: self-contained breathing apparatus and full protective clothing.
