IV. FIRE AND EXPLOSION HAZARDS DATA
Flash Point (Method Used): N/A
Autoignition Temp.: 400 oC (powder)
Flammable Limits: Upper: N/A Lower: N/A
Extinguishing Media: Non combustible except in powder form use water spray or fog, dry chemical extinguishing agents, carbon dioxide, dry sand.
Special Fire Fighting Procedures: Wear NIOSH/MSHA approved self contained breathing apparatus and protective clothing. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.
Unusual Fire & Explosion: Ignites and is potentially explosive in atmospheres of carbon dioxide. Chromium react violently or explosively when heated with ammonium nitrate and bromine pentafluoride. It has an incandescent reaction with nitrogen oxide or sulfur dioxide. Powders prepared by evaporation of mercury form chromium amalgam may be pyrophoric.
V. HEALTH HAZARD INFORMATION
Effects of Exposure:
Chromium is a confirmed human carcinogen with experimental tumorigenic data. Also a human poison by ingestion with gastrointestinal effects.
Acute Effects:
Inhalation: May cause a red, dry throat.
Ingestion: May cause gastrointestinal disorders.
Skin: May cause abrasive irritation.
Eye: May cause abrasive irritation.
Chronic Effects:
Inhalation: May cause histologic fibrosis of lungs, nasal and/or lung cancer.
Ingestion: No chronic health effects recorded.
Skin: No chronic health effects recorded.
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: Yes OSHA: Yes
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove victim to fresh air. Keep warm and quiet, give oxygen if breathing is difficult and seek medical attention.
INGESTION: Give 1-2 glasses of milk or water and induce vomiting. Seek medical attention immediately. Never induce vomiting or give anything by mouth to an unconscious person.
SKIN: Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water. Seek medical attention if symptoms persist.
EYE: Flush with lukewarm 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: Grinding, crushing, and melting may produce dust and fumes which may require control.
Incompatibility (Material to Avoid): Powder incompatible with ammonium nitrate, hydrogen peroxide, nitric oxide, potassium chlorate, sulfur dioxide, mercury. Otherwise, avoid strong oxidizing agents, ammonium nitrite, bromine pentafluoride and carbon dioxide.
Hazardous Decomposition Products: Toxic chromium oxides fumes
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-Special Protection Information. Isolate spill area, provide ventilation and extinguish sources of ignition. 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. Use non-sparking tools.
Waste Disposal Method: Consult Local, State, and Federal Regulations for proper disposal procedures.
VIII. SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): NIOSH/MSHA approved respirator for dusts and mists.
Ventilation: Use local exhaust to maintain concentration at or below PEL, TLV levels.
Protective Gloves: Rubber gloves
Eye Protection: Safety glasses
Other Protective Equipment: Protective gear suitable to prevent contamination.
IX. SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in cool, dry area. Store in tightly sealed container. Protect against physical damage. Store away from acids and oxidizers. Wash thoroughly after handling.
Precautionary Labeling: CAUTION! Do not swallow or inhale. Avoid contact with skin and eyes. Wash Thoroughly after handling. Keep container closed.
Work Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure. 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.
