Exposure Standards and Regulations
In accordance with 21 CFR 184.1(b)(1), the ingredient is used in food with no limitation other than current good manufacturing practice. The affirmation of this ingredient as generally recognized as safe (GRAS) as a direct human food ingredient is based upon the following current good manufacturing practice conditions of use: 1) The ingredient is used as a nutrient supplement as defined in 21 CFR 170.3(o)(20) of this chapter and as a processing aid as defined in 21 CFR 170.3(o)(24) of this chapter. 2) The ingredient is used in food at levels not to exceed current good manufacturing practice. Copper sulfate may be used in infant formula in accordance with section 412(g) of the Federal Food, Drug, and Cosmetic Act (the act) or with regulations promulgated under section 412(a)(2) of the act. Prior sanctions for this ingredient different from the uses established in this section do not exist or have been waived.
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.)
Reactivities and Incompatibilities
Anhydrous copper sulfate causes hydroxylamine to ignite & the hydrated salt is vigorously reduced.
Solutions of sodium hypobromite are decomposed by powerful catalytic action of cupric ions, even as impurities. /Cupric salts/
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.
If material not involved in fire: Keep material out of water sources & sewers. Build dikes to contain flow as necessary.
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.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers.

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.
Group III Containers (both combustible and non-combustible) that previously held organic mercury, lead, cadmium, arsenic, or inorganic pesticides should be triple rinsed, punctured and disposed of in a sanitary landfill. Non-rinsed containers should be encapsulated and buried at a specially designated landfill site. /Organic mercury, lead, cadmium, arsenic, or inorganic pesticides/
The following wastewater treatment technologies have been investigated for copper (II) sulfate: activated carbon.
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. ... The sludge may be added to landfill. Recommendable methods: Precipitation, solidification, & landfill. Peer-review: ... Copper can be recovered by cation exchange.

10.3 Possibility of hazardous reactions

Anhydrous CUPRIC SULFATE serves as a weak oxidizing agent. Causes hydroxylamine to ignite. Gains water readily. The hydrated salt is vigorously reduced by hydroxylamine [Mellor 8:292(1946-1947)]. Both forms are incompatible with finely powdered metals. Both are incompatible with magnesium, corrode steel and iron, may react with alkalis, phosphates, acetylene gas, hydrazine, or nitromethane, and may react with beta-naphthol, propylene glycol, sulphathiazole and triethanolamine if the pH exceeds 7 . Both act as acidic salts, corrode metals and irritate tissues.
