4. Safety and Handling

4.1 Other Preventative Measures: SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.
If material not involved in fire: Keep material out of water sources and sewers. Build dikes to contain flow as necessary.
Personnel protection: Keep upwind. ... Avoid breathing vapors or dusts. Wash away any material which may have contacted the body with copious amounts of water or soap and water.

4.2 Cleanup Methods: Environmental considerations: Land Spill: Dig a pit, pond, lagoon or holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire-fighting water.
Environmental considerations: Water Spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Add soda ash (NaCo3). Adjust pH to neutral (pH 7).

4.3 DisposalMethods: SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

7.Other Information

Chemical Properties: Lithium chromate is a yellow crystalline powder.

General Description: A yellow crystalline solid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Lithium chromate is used as a corrosion inhibitor and in the manufacture of other chemicals.

Air & Water Reactions: Deliquescent. Water soluble

Reactivity Profile: Lithium chromate is an oxidizing agent. Can oxidize combustibles [USCG, 1999]. Combining the chromate with zirconium can be explosive given the right proportions of reactants, [Z. Anorg., 1930, 191, 113].

Health Hazard: INHALATION: Corrosive to skin and mucous membranes causing dermatitis and slow healing ulcers. EYES: Conjunctivitis and lacrimation. INGESTION: Violent gastroenteritis, peripheral vascular collapse, vertigo, muscle cramps, coma, hemorrhagic diathesis, fever, liver damage and renal failure.

Potential Exposure: Used as a corrosion inhibitor, heat transfer agent; and oxidizing agent in leather and metal finishing. Also used in photography, wood preservatives; batteries, safety matches, and cement

First aid: If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.
