Autoignition Temperature: N/A
Flammable Limits: Upper: N/A Lower: N/A
Flammability: Non-flammable.
Extinguishing Media: Use extinguishing media appropriate for surrounding fire.
Special Fire Fighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing ot prevent contact with skin and eyes. Move containers from fire area if it can be done without risk. Use water to keep fire-exposed containers cool.
Unusual Fire & Explosion Hazard: When heated to decomposition this material may emit toxic metal oxide fumes. Chromium oxide is a powerful oxidizer. May have a violent reaction with ClF3.
V. HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical, and toxicological properties of chromium oxide have not been thoroughly investigated and reported.
Chromium is a confirmed carcinogen with experimental tumorigenic data. Mutation data reported. Chromate salts are suspected human carcinogens producing tumors of the lungs, nasal cavity, and paranasal sinus. Chromic acid and its salts have a corrosive effect of the skin and mucous membranes. The lesions are confined to the exposed parts, affecting chiefly the skin of the hands and forearms and the mucous membranes of the nasal septum. Hexavalent compounds are more toxic than the trivalent. (Sax, Dangerous Properties of Industrial Materials.)
Acute Effects:
Inhalation: Toxic by inhalation and is a severe irritant to the mucous membranes.
Ingestion: Toxic by ingestion which may cause gastrointestinal disorders.
Skin: Severe skin irritant.
Eye: Severe eye irritant.
Chronic Effects:
Inhalation: May cause histologic fibrosis of the lungs, nasal and/or lung cancer.
Ingestion: No chronic health effects recorded.
Skin: May cause eczematous dermatitis.
Eye: No chronic health effects recorded.
Target Organs: May affect the respiratory system.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders, pulmonary functions and asthma.
Carcinogenicity: NTP: Yes IARC: No OSHA: Yes
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek immediate medical advice.
INGESTION: Give 1-2 glasses of milk or water and induce vomiting. Seek immediate medical advice. Never induce vomiting or give anything by mouth to an unconscious person.
SKIN: Remove contaminated clothing, brush materia off skin, wash affected area with water and soap and rinse thoroughly. Seek medical attention if symptoms persist.
EYES: Flush eyes with plenty of water, lifting upper and lower eyelids for at least 15 minutes. Seek medical attention if symptoms persist.
VI. REACTIVITY DATA
Stability: Stable
Conditions to Avoid: Dusting.
Incompatibility (Material to Avoid): Lithium, glycerol, oxidizing agents, acids, interhalogens, bases.
Hazardous Decomposition Products: Metal oxide fume.
Hazardous Polymerization: Will not occur.
VII. SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Wear appropriate respiratory and protective equipment specified in section VIII. Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust.
Waste Disposal Method: Dispose of in accordance with applicable Federal, State and Local regulations.
EPA Hazardous Waste Number: D007 (EP Toxic Waste)
VIII. SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): Respiratory protection required if airborne concentration exceeds TLV. At concentrations up to 1 ppm, a dust/mist respirator is recommended. Above this level, a self-contained breathing apparatus is advised.
Ventilation: Use local exhaust ventilation to meet PEL’s and TLV’s. Handle in dry, controlled atmosphere.
Protective Gloves: Impervious gloves
Face Protection: Safety goggles
Other Protective Equipment: Protective gear suitable to prevent contamination.
IX. SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in tightly closed containers in a cool, dry place. Do not store together with oxidizing and acidic materials. Wash thoroughly after handling.
U.S. Precautionary Labeling: WARNING! Causes Irritation. Caution: Cancer Hazard. Harmful If Swallowed or Inhaled. Exceptional Health Hazard: Read Material Safety Data Sheet. Avoid contact with eyes, skin, clothing. Avoid breathing dust. Keep in tightly closed container. Use with adequate ventilation. Wash throughly after handling.
International Labeling: Avoid contact with eyes. After contact with skin, wash immediately with plenty of water. Keep container tightly closed.
Work Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air. Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
