IV FIRE AND EXPLOSION H AZARDS DATA
Autoignition Temp.: 400 oC (pow der)
Flash Point (Method Used): N/A
Flam mab le Limits: Upper: N/A Lower: N/A
Extingu ishing Media: Non combustible except in powder form use water spray or fog, dry chemical extinguishing agents, carbon
dioxide, dry sand.
Special Fire Fighting Procedures: We ar NIOS H/M SH A approve d 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 amm onium nitrate and bromine pentafluoride. It has an incandescent reaction with nitrogen oxide or
sulfur dioxide. Powders prepared by evaporation of mercury form chrom ium amalgam m ay be pyrophoric.

EMERG ENCY 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.
SK IN: Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water. Seek medical attention
if sym ptom s persist.
EYE: Flush with lukewarm water, lifting u ppe r and lower eyelids fo r at least 15 m inutes. Seek me dical attention if sym ptom s persist.

VII SPILL OR LEAK PROC EDURES
Steps to be Taken in Case Material is Released or Spilled: We ar appropriate respira tory and protective equipm ent specified in
Section VIII-Special Protection Information. Isolate spill area, provide ventilation and extinguish sources of ignition. Vacuum up
spill usin g a high efficiency particulate absolute (HE PA ) air filter an d place in a closed container for proper disp osal. T ake care n ot to
raise dust. Use non-sparking tools.
Waste Disposal Method: Consu lt Local, State, and Federa l Regu lations for pro per dispo sal proced ures.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): NIOSH/M SHA appro ved respirator for dusts and m ists.
Ventilation: Use local ex haust to m aintain con centration a t 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 coo l, dry area. Store in tightly sealed co ntainer. Protect against
physical damage. Store away from acids and oxidizers. Wash thoroughly after handling.
Precautionary Labeling: CAUTIO N! Do not swallow or inhale. Avoid contact with skin and eyes. Wash Thoroug hly after
handling. Keep container closed.
Wo rk 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.
