- 【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 contained with a flexible impermeable 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, or sodium bicarbonate. Add soda ash. Adjust pH to neutral (pH 7). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
- 【Protective Equipment and Clothing】
- Dust irritating to eyes, nose and throat. Solid irritating to skin and eyes.
- 【Disposal Methods】
- 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.

- FOLLOWING ORAL ADMIN, BROMIDE SALTS ARE RAPIDLY ABSORBED FROM LOWER PART OF SMALL INTESTINE. WHEN USED AS SEDATIVE IN ADULTS, THERAPEUTICALLY EFFECTIVE BLOOD LEVEL OF BROMIDES IS 0.5-0.6...(MEQ)/LITER. ... BROMIDE IS WIDELY DISTRIBUTED THROUGHOUT EXTRACELLULAR FLUIDS INCLUDING SECRETIONS & TRANSUDATES. /BROMIDES/
...BROMIDES CROSS THE PLACENTA. RENAL EXCRETION OF BROMIDE IS VERY SLOW. BIOLOGIC HALF-LIFE OF BROMIDE IS ABOUT 12 DAYS IN PT WITH NORMAL CHLORIDE INTAKE. MAX ACCUM DOES NOT OCCUR FOR APPROX 2 MO. LOW CHLORIDE INTAKE FACILITATES ACCUM OF BROMIDE BY REDUCING ITS URINARY EXCRETION. /BROMIDES/
ALTHOUGH RENAL EXCRETION OF BROMIDE IS SIMILAR TO THAT OF CHLORIDE, TUBULAR REABSORPTION OF BROMIDE IS MORE EFFICIENT THAN THAT OF CHLORIDE & THUS KIDNEYS EXCRETE CHLORIDE PREFERENTIALLY TO BROMIDE. ... SMALL AMT OF BROMIDE ARE EXCRETED IN SWEAT & FECES. /BROMIDES/

Upon intravenous injection zinc is distributed to erythrocytes, plasma, and leukocytes; about 80% of the zinc present in the blood is found in the erythrocytes, 12-20% in the plasma, and about 3% in the leukocytes. ... There is a dynamic exchange of zinc between plasma and erythrocytes. Inhalation of dusts of zinc salts results in a transient accumulation in the lung before its absorption into the blood. There is little absorption of zinc or its salts through the skin. ... About 80% of parenterally administered zinc is excreted in the feces, suggesting an enterohepatic circulation for zinc. In humans, about 10% of the absorbed zinc is excreted in the urine, and in tropical climates about 2-3 mg zinc/day may be lost in sweat. /Soluble zinc compounds/
