Hazards and Protection.
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale. Discard contaminated shoes.
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Vacuum or sweep up material and place into a suitable disposal container. Avoid generating dusty conditions.
Stable under normal temperatures and pressures.
Keep away from combustible materials. may casue a fire. Under certain conditions, dry mixtures of chromates with azo-dyes may lead to violent explosions during mixing or blending operations. Hydrazine is decomposed explosively by chromates.
Toxic fumes of sodium oxide, toxic chromium oxide fumes.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing media: For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam.
Non-combustible it can react with combustible materials and the heat of this reaction may be sufficient to result in the ignition of the combustible material.
Behavior in fire: May increase intensity of fire when in contact with combustible material.
Toxic chromium oxide fumes may form in fire.
TLV: 0.025 ppm; 0.16 mg/m3 (ACGIH 1991-1992). NIOSH REL: Ca 0.001 mg Cr(VI)/m3 See Appendix A See Appendix C NIOSH IDLH: Potential occupational carcinogen

Prolonged or repeated eye contact may cause conjunctivitis. Prolonged or repeated skin contact may cause sensitization dermatitis and possible destruction and/or ulceration. Prolonged or repeated exposure may lead to asthma and perforation of the nasal septum. Prolonged or repeated contact may cause skin necrosis and/or ulceration of the skin. May cause cancer in humans. Chronic exposure may cause acute hepatitis with jaundice.
May be fatal if swallowed. May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. May cause liver and kidney damage. May cause perforation of the digestive tract. May cause hemorrhaging of the digestive tract.
Causes respiratory tract irritation. May cause ulceration and perforation of the nasal septum if inhaled in excessive quantities.
May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. May cause deep, penetrating ulcers of the skin. May be absorbed through the skin. May cause severe irritation and possible burns.
Contact with eyes may cause severe irritation, and possible eye burns.
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
