3. Use and Manufacturing
3.1 Definition
A green mineralconsisting of copper(II) carbonate and hydroxide(CuCO3.Cu(OH)2). It is used as anore and a pigment.
3.2 Potential Exposure
Copper sulfate is used as intermediate and wood preservative; also used in production of copper compounds; to detect and to remove trace amounts of water from alcohols and organic compounds; as a fungicide and algicide; in veterinary medicine and others.
3.3 Shipping
UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.
3.4 Usage
Used as a source of Cu2+ ions
3.5 Waste Disposal
Copper-containing soluble wastes can be concentrated through the use of ion exchange, reverse osmosis, or evaporators to the point where copper can be electrolytically removed and sent to a reclaiming firm. If recovery is not feasible, the copper can be precipitated through the use of caustics and the sludge deposited in a chemical waste landfill Add soda ash to waste CuSO4 solution; let stand 24 hours. Decant and neutralize solution before flushing to sewer. Landfill sludge. Copper sulfate pentahydrate Preparation Products And Raw materials Raw materials

4.1 Exposure Standards and Regulations
Trace minerals added to animal feeds. These substances added to animal feeds as nutritional dietary supplements are generally recognized as safe when added are levels consistent with good feeding practice. Element: Copper; Source compound: copper sulfate. (All substances listed may be in anhydrous or hydrated form.)
4.2 Packing Group
III
4.2 Fire Hazard
Literature sources indicate that Copper sulfate pentahydrate is nonflammable.
4.3 Other Preventative Measures
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. /Cupric sulfate/
If material not involved in fire: Keep material out of water sources & sewers. Build dikes to contain flow as necessary. /Cupric sulfate/
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.
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.

4.4 Cleanup Methods
Environmental concerns - land spill: Dig a pit, 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. /Cupric sulfate/
Environmental concerns - water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Adjust pH to neutral (pH= 7). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates. /Cupric sulfate/
Add slowly to a large container of water. Stir in slight excess of soda ash. Let stand for 24 hr. Decant or siphon into another container & neutralize with 6 molar hydrochloric acid before washing down drain with large excess of water. The sludge may be added to landfill.
4.5 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.
Add slowly to a large container of water. Stir in slight excess of soda ash. Let stand for 24 hr. Decant or siphon into another container and neutralize with 6 M HCl before washing down drain with large excess of water. The sludge may be added to landfill. Recommendable methods: Precipitation, solidification, & landfill. Peer-review: Precipitate with calcium hydroxide. Dilute supernatant and discharge to sewer. Copper can be recovered by cation exchange. (Peer-review conclusions of an IRPTC expert consultation (May 1985))
