Chemical: Sulfuric acid, copper(2+) salt (1:1), pentahydrate

Sulfuric acid copper(2+) salt (1:1), pentahydrate is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Sulfuric acid copper(2+) salt (1:1), pentahydrate are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)

Copper sulphate, pentahydrate: Does not have an individual approval but may be used under an appropriate group standard

Literature sources indicate that this compound is nonflammable. (NTP, 1992)

Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. Many reactions may cause fire or explosion. See Chemical dangers

SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin, eyes, respiratory tract and gastrointestinal tract. Ingestion can cause severe gastroenteric distress (vomiting, pain, localized corrosion, and hemorrhages), prostration, anuria, hematuria, anemia, increased number of white blood cells, icterus, coma, respiratory difficulty and circulatory failure. It can also cause nausea, metallic taste, sweating, headache, burning sensation in the esophagus and stomach, abdominal pain, hemorrhagic gastritis, weak pulse, melena, conjunctivitis, corneal ulceration, hypotension and turbidity. Other symptoms may include watery and bloody stools, burning in the mouth and throat, liver damage with jaundice, hemolysis, tenesmus, retching, collapse and convulsions. Uremia, shock and renal failure have been reported. Skin contact can cause smarting and first degree burns on short exposure. Prolonged exposure can result in second degree burns. Persons with preexisting Wilson's disease may be more susceptible to these effects.

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.)

COPPER SULFATE PENTAHYDRATE can be dehydrated by heating. 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 (NTP, 1992). Both act as acidic salts, corrode metals and irritate tissues.

The solution in water is a weak acid. Decomposes on heating. This produces toxic fumes of sulfur oxides (see ICSC 0074). Reacts violently with hydroxylamine. This generates fire hazard. Reacts with acetylene and potassium chlorate. This generates explosion hazard. Reacts with magnesium powder. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Attacks some metals in the presence of water.

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)

In case of fire in the surroundings, use appropriate extinguishing media.

Fresh air, rest.

Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.

Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

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.

SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

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))

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance, protective gloves, protective clothing and safety goggles. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Then store and dispose of according to local regulations.

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.

The milk of female vineyard workers, who were exposed to copper sulfate and a variety of other pesticides, contained 6.2 times as much copper as the milk of milkmaids who did equally hard work but not exposed to pesticides. Placentas from the vineyard workers contained 4.7 times more copper than those from milkmaids. ... Copper ... occurs in all tissues. ... The concn in blood, muscle, and most of the viscera range from 0.85 to 1.90 ppm. Values for plasma lie in the narrow range of 1.16 to 1.42 ppm. The concn in the brain (2.2 to 6.8 ppm), liver (7.1 ppm in adults and 24 ppm in infants), and bone (3.7 to 4.7 ppm in rib and 6.8 ppm in long bones) are higher.
