Inhalation Inhalation of dust or mist may irritate the nasal septum and respiratory tract. Destructive to tissues of mucous membranes. Prolonged or repeated exposure may cause ulceration and perforation of the nasal septum. May cause headache, nausea, vomiting, chemical pneumonitis and pulmonary edema. May cause sensitization by inhalation. Can cause liver, kidney, and lung damage.

Ingestion Burns in mouth, pharynx and gastrointestinal tract (Can cause severe tissue destruction.). May cause vomiting, nausea, abdominal pain, diarrhea, coma, bleeding and/or tissue ulceration, gastroentritis, toxic nephritis, blood and bone marrow damage, liver and kidney failure, peripheral vascular collapse and death. Section V. Toxicological Properties SODIUM CHROMATE, ANHYDROUS page 3/4 Effects of Chronic Dermatitis, conjunctivitis, "chrome sores", ulceration and perforation of the nasal septum, chronic bronchitis, Overexposure bronchopneumonia, pneumoconiosis, rhinitis, emphysema, gastrointestinal disturbances. There is sufficient evidence of the carcinogenicity of this substance in humans (known carcinogen). This substance is known to cause allergic reactions in certain individuals once they become sensitized after exposure to even small amounts over a period of time. Chromium(VI) compounds in the form of chromates and dichromates have been found to be mutagenic in bacterial and mammalian cells, including those of the chinese hamster. Teratogenic effects: Not available. Toxicity of the product to the reproductive system: Not available. Passes through the placental barrier in animal. To the best of our knowledge, the chemical, physical, and toxicity of this substance has not been fully investigated.

Section VI. First Aid Measures Eye contact IMMEDIATELY flush eyes with copious quantities of water for at least 15 minutes holding lids apart to ensure flushing of the entire surface. Washing within 1 minute is essential to achieve maximum effectiveness. Seek immediate medical attention.

Skin contact Immediately flush skin with plenty of water and soap for at least 15 minutes while removing contaminated clothing and shoes. Seek immediate medical attention. Wash contaminated clothing before reusing. Discard contaminated leather articles such as shoes and belt.

Inhalation Remove patient to fresh air. Administer approved oxygen supply if breathing is difficult. Administer artificial respiration or CPR if breathing has ceased. Seek immediate medical attention.

Ingestion If conscious, wash out mouth with water. Have conscious person drink several glasses of water or milk. DO NOT induce vomiting. If spontaneous vomiting occurs, have victim lean forward with head down to avoid breathing in of vomitus, rinse mouth and administer more water. Seek immediate medical attention. Never give anything by mouth to an unconscious or convulsing person. Accident victims should be given 5-10 g ascorbic acid (not effervescent tablets) dissolved in water. This dose can be repeated several times.

Preventive Measures SODIUM CHROMATE, ANHYDROUS page 4/4 Protective Clothing in Wear self-contained breathing apparatus, rubber boots and heavy rubber gloves. Full suit. case of spill and leak

Spill and leak Evacuate the area. Eliminate all sources of ignition. Sweep up and place in container for disposal. Avoid raising dust. Use non-sparking tools. Ventilate area and wash spill site after material pick up is complete. DO NOT empty into drains. DO NOT touch spilled material. Avoid contact with a combustible material (wood, paper, oil, clothing...).

Waste disposal According to all applicable regulations. Harmful to aquatic life at very low concentrations. Can be dangerous if allowed to enter drinking water intakes. Do not contaminate domestic or irrigation water supplies, lakes, streams, ponds, or rivers.

Storage and Handling Store in a cool place away from heated areas, sparks, and flame. Store in a well ventilated area. Store away from incompatible materials. Do not add any other material to the container. Do not wash down the drain. Do not breathe dust. In case of insufficient ventilation, wear suitable respiratory equipment. Keep away from combustible material. Keep away from direct sunlight or strong incandescent light. Keep container tightly closed and dry. Manipulate under an adequate fume hood. Avoid raising dust. Use non-sparking tools. Empty containers may contain a hazardous residue. Handle and open container with care. Minimize dust generation and exposure - use dust mask or appropriate protection. Take off immediately all contaminated clothing. Avoid contact with a combustible material (wood, paper, oil, clothing...). This product must be manipulated by qualified personnel. Do not get in eyes, on skin, or on clothing. Wash well after use. In accordance with good storage and handling practices. Do not allow smoking and food consumption while handling.

Section IX. Protective Measures Protective clothing Face shield and splash goggles. Impervious rubber gloves, apron, coveralls, and/or other resistant protective clothing. Sufficient to protect skin. A OSHA/MSHA jointly approved respirator is advised in the absence of proper environmental controls. If more than TLV, do not breathe vapor. Wear self-contained breathing apparatus. Do not wear contact lenses. Make eye bath and emergency shower available. Ensure that eyewash station and safety shower is proximal to the work-station location. Engineering controls Use in a chemical fume hood to keep airborne levels below recommended exposure limits. Do not use in unventilated spaces.

Section X. Other Information Special Precautions or Powerful oxidizing agent; may ignite oxidizable materials. Highly toxic! Severe irritant! comments Prolonged exposure may result in skin burns and ulcerations. Carcinogen! Mutagen! Sensitizer! Possible risks of irreversible effects. Toxic effects may be delayed. Do not breathe dust. Avoid all contact with the product. Avoid prolonged or repeated exposure. Use in a chemical fume hood. Keep away from heat, sparks and flame. Use non-sparking tools. When contaminated, it is very sensitive. Contact with other material may form shock, heat or friction sensitive mixtures. Handle and open container with care. Container should be opened only by a technically qualified person. NOTE TO PHYSICIAN: Massive overexposure to solutions of this product could lead to kidney failure and death. Death has been avoided in several such cases through the use of early renal dialysis. It has been reported there is little value from chelating agents, however, that ascorbic acid administered intravenously is an effective antidote in preventing renal failure. Skin ulcers may be treated by removal from exposure, daily cleansing and debridement, and application of antibiotic cream and dressing. NFPA RTECS NO: GB2955000 (Sodium chromate).
