Health Effects
Acute - Swallowed
Harmful if swallowed. Copper salts impart a metallic taste in the mouth. Burning sensation in the throat and repeated vomiting are typical effects. More severe poisonings cause diarrhoea and ulceration of the gastrointestinal tract. Can be fatal.
Acute - Eye
Will cause irritation in contact with the eyes. Dilute copper sulphate solutions have been used as topical antibiotics. Copper sulphate particles in the eye could cause local inflammation, tissue destruction (necrosis), corneal opacity and adhesion of the eyelid to the eye. Traces of sulphuric acid impurity may contribute to these effects.
Acute - Skin
Will cause irritation in contact with the skin, which will result in redness, itchiness, and possible dermatitis.
Acute -Inhaled
May cause irritation to the mucous membrane and upper airways. Dusts and mists (copper solutions) may also cause irritation of the nasal passages and throat. Ulceration of the nasal septum is possible, but may be due to traces of sulphuric acid impurities.
HEALTH EFFECTS SKIN: Repeated or prolonged exposure to copper salts can cause irritation, producing itching and redness of the skin. Some individuals may become sensitized to copper sulfate and develop allergic contact dermatitis.
INHALATION: Repeated inhalation of copper sulfate mists (e.g. Bordeaux mixture) may induce a condition known as 'vineyard sprayer's lung'. Greenish-tumours occur in the liver and lungs of afflicted individuals. The disease is asymptomatic until later stages. Symptoms include weakness, malaise, loss of appetite and weight, cough and greenishbrown sputum.
INGESTION: Chronic occupational exposure to copper sulfate by ingestion is not likely. Symptoms would be like those of Wilson's disease, which include liver, brain, muscle and kidney disfunction.
Other Information
CARCINOGENICITY Although some individuals afflicted with 'vineyard sprayers' lung' developed lung cancer, there is no indication of an increased incidence of cancer due copper sulfate exposure, per se.
TERATOGENICITY AND EMBRYOTOXICITY There are no reports of teratogenicity or embryo toxicity in humans. Animal studies indicate that a deficiency or embryo toxicity in humans. Animal studies indicate that a deficiency or excess of copper in the body can cause significant harm to developing embryos. The net absorption of copper is limited and embryo toxic levels are unlikely from industrial exposure.
MUTAGENICITY No human data available. Negative or inconclusive results in short-term tests.
POTENTIAL FOR ACCUMULATION Copper is an essential element and its level in the body is strictly controlled. Under most conditions, excess copper is excreted in the urine and feces (via the bile).
HEALTH HAZARD COMMENTS Copper salts may decrease the toxicity of molybdenum.
Zinc salts may decrease the toxicity of copper salts.

Immediately wash out mouth with water, and then give plenty of water to drink. SEEK IMMEDIATE MEDICAL ATTENTION.
If in eye wash with copious amounts of water for approximately 15 minutes holding eyelid open. Take care not to rinse contaminated water into the non-affected eye. SEEK MEDICAL ATTENTION.
Remove contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Wash gently and thoroughly with water and non-abrasive soap. Ensure contaminated clothing is washed before re-use or discard. If contact is more than of minor nature, SEEK MEDICAL ATTENTION.
Remove the source of contamination or move the victim to fresh air. Ensure airways are clear and have a qualified person give oxygen through a face mask if breathing is difficult. SEEK MEDICAL ATTENTION.
First Aid Facilities
Safety showers, eye wash fountains, and normal wash room facilities.
Other Information
Consult a doctor and/or the nearest Poison Control Centre for all exposures except minor instances of inhalation or skin contact. All first aid procedures should be periodically reviewed by a doctor familiar with the material and its conditions of use in the workplace. Advice to Doctor Treat symptomatically or consult Poison Information Centre.


Other Health Hazard Information
Exposure Limits
Copper, dusts & mists (as Cu) TWA: 1 mg/m3
Copper (fume) TWA: 0.2 mg/m3


Engineering Controls: Engineering control methods to reduce hazardous exposures are preferred. Methods include mechanical ventilation (dilution and local exhaust), process or personnel enclosure, control of process conditions, and process modification (e.g., substitution of a less hazardous material). Administrative controls and personal protective equipment may also be required. Use local exhaust ventilation, and process enclosure if necessary, to control airborne dust or mist. Locate dust collectors outside or where permitted by regulation. Supply sufficient replacement air to make up for air removed by exhaust system.

RESPIRATORY PROTECTION: The use of a Class P2 full facepiece respirator with replaceable filter complying with AS/NZS 1715 and AS/NZS 1716 is recommended.
EYE PROTECTION: The use of face shields, chemical goggles, or safety glasses with side shield protection is recommended.
HAND PROTECTION: The use of Nitrile rubber gloves is recommended.
CLOTHING: The use of plastic apron, sleeves, overalls, and rubber boots are recommended.
Work / Hygienic Practices
Avoid eye contact and repeated or prolonged skin contact. Wear overalls, safety glasses and impervious gloves. If risk of inhalation of spray mists exists, wear combined organic vapour / particulate respirator meeting the requirements of AS/NZS 1715 and AS/NZS 1716. Always wash hands before smoking, eating, drinking or using the toilet. Wash
contaminated clothing and other protective equipment before storing or re-using.

Flammability: Fire Hazards In common with many organic chemicals, may form flammable dust clouds in air. For precautions necessary refer to safety information on dust explosion hazards. Not combustible.


Storage and Transport
