Section 4 - First Aid Measures
Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin: Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.
Ingestion: Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician: Individuals with Wilson's disease are more susceptible to chronic copper poisoning.
Section 5 - Fire Fighting Measures
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dust can be an explosion hazard when exposed to heat or flame. Flammable solid. May burn rapidly with flare burning effect. May re-ignite after fire is extinguished. Finely divided dusts may exhibit pyrophoric tendencies.
Extinguishing Media: Use dry sand, Met-L-X powder, or G-1 graphite powder. Contact professional fire-fighters immediately. Use dry sand, graphite powder, dry sodium chloride-based extinguishers. Dousing metallic fires with water may generate hydrogen gas, an extremely dangerous explosion hazard, particularly if fire is in a confined environment.

Scoop up with a nonsparking tool, then place into a suitable container for disposal. Avoid generating dusty conditions. Remove all sources of ignition.
Section 7 - Handling and Storage
Handling: Use personal protective equipment as required. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with skin and eyes. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep away from heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Contaminated work clothing should not be allowed out of the workplace.

Carcinogenicity:

Epidemiology: No data available.
Teratogenicity: No data available.
Reproductive Effects: No data available.
Mutagenicity: Genotoxicity Effects. Several in vitro studies (Table 2-4) have examined genotoxic effects of copper in nonhuman systems. The results of the tests using prokaryotic organisms are equivocal. However, positive results have been observed in vitro (Table 2-4) and in vivo (Table 2-5) in mammalian systems. At low levels of copper (0.01-0.1 mM Cu as copper sulfate), DNA strand breaks were not observed in rat hepatocytes; however, strand breaks did occur at high concentrations (0.04 mM Cu as copper sulfate) (Sina et al. 1983). In vivo studies with Inbred Swiss mice showed that copper exposure resulted in chromosomal aberrations and micronuclei and sperm abnormalities (Bhunya and Pati 1987). Copper binds with the phosphate on nucleotides and nucleic acids of DNA. Its mutagenic potential may be the result of this binding (Sharma and Talukder 1987).
Although there is no data on the mutagenicity of copper in humans, in vivo studies and mammalian system in vitro studies suggest that copper is a potential human mutagen.

Other Studies: EndPoint:
Primary Organ: Renal toxicity (Kidney)
7.3.1 Oral
7.3.1.1 Copper(II) sulfate
The critical study is that of Hébert et al. (1993) which is described here. In comprehensive 90-day studies in both rats and mice (Hébert et al., 1993), in which copper(II) sulfate pentahydrate was administered in the feed at up to 8000 mg/kg in rats (up to 138 mg Cu/kg body weight per day) and up to 16 000 mg/kg in mice (up to around 1000 mg Cu/kg body weight per day), there were no overt signs of toxicity other than a dose-related reduction in growth (statistically significant in male and female rats from 67 and 138 mg Cu/kg body weight per day, respectively, and in male and female mice from 97 and 267 mg Cu/kg body weight per day). Microscopic examination of the tissues revealed hyperplasia and hyperkeratosis in the forestomach in both species (from 34 mg Cu/kg body weight per day in rats and from 187-267 mg Cu/kg body weight per day in mice), and liver and kidney effects in the rats only (from 67 mg Cu/kg body weight per day). In the rats, iron levels were reduced in the spleen, and haematological changes indicative of microcytic anaemia were observed at 34 mg Cu/kg body weight per day and higher. The NOEL was 17 mg Cu/kg body weight per day in rats, and 44 and 126 mg Cu/kg body weight per day in male and female mice, respectively. The liver and kidney effects observed in the rats in this study included inflammation of the liver and degeneration of the kidney tubule epithelium, and were similar to those found at higher doses (> 100 mg Cu/kg body weight per day) in more limited studies in rats (Haywood, 1980, 1985; Haywood & Loughran, 1985).
7.4 Long-term exposure chronic toxicity or carcinogenicity
The chronic toxicity/carcinogenicity of copper compounds has not been well characterized (see Table 11). Increased mortality and growth retardation or effects on the liver, kidneys or stomach have been observed in rats following long-term ingestion of 27-150 mg Cu/kg body weight per day as copper(II) sulfate, or 44-45 mg Cu/kg body weight per day as copper(II) acetate, in several limited studies. Long-term ingestion of copper(II) sulfate at 10 mg Cu/kg body weight per day induced marked hepatotoxicity in rabbits. An oral study in dogs did not show significant toxic effects at the highest dose of 8.4 mg Cu/kg per day, given as copper gluconate (Shanaman et al., 1972).
The available studies of the carcinogenicity of copper compounds in rats and mice have given no indication that copper salts are carcinogenic. However, the short duration or low level of exposure, the small group sizes employed, the limited extent of histopathological examination, or inadequate reporting limits the conclusions which can be drawn from such studies. The studies summarized in Table 11 are, therefore, inadequate to test the carcinogenic potential of copper compounds with any degree of certainty. In several studies, administration of copper compounds inhibited the development of tumours induced by known carcinogens (see Table 11).

EndPoint:
Primary Organ:
Immunotoxicity
In an inhalation study in mice, single or repeated 3 h exposures to copper(II) sulfate aerosol resulted in significant immunosuppressive effects, including reduced bactericidal activity of the alveolar macrophages to Klebsiella pneumoniae and reduced resistance to infection by Streptococcus zooepidemicus. These effects were evident after a single exposure at 0.28 mg Cu/m3 and above and after 5 or 10 daily exposures at 0.06-0.07 mg Cu/m3. A NOEL was not established in these studies (Drummond et al., 1986).

Remark: Inhalation:
Copper fumes cause irritation of the eyes, nose and throat, and a flu-like illness called "metal fume fever". Symptoms of metal fume fever include fever, muscle aches, nausea, chills, dry throat, cough and weakness. The symptoms disappear after 24 hours. Metal fume fever appears after exposure to about 0,1 mg/m3. Repeated or prolonged exposure to copper fumes may cause the skin and hair to change
colour. Renal damage reported. Nasal perforation reported in some cases. Chronic health affects, such as respiratory symptoms, gastrointestinal disturbances, nervous dysfunctions, dermatological and haematological changes and hepatomegaly. 75-100 copper workers, who were heavily exposed to copper dust of high purity, were examined over a 4-year period. The main findings were:
- in workers with Cu-S between 0,8-2,0 mg/l: increased alpha-2-globulins, redblood-cells and haemoglobin;
- in workers with Cu-S above 2,0 mg/l: different nervous symptoms, enlarged livers, abdominal distension and dermatological manifestations. Chronic irritative bronchitis was also observed.
Lung damage following chronic exposure to copper dusts and fumes in industry is not described.
The higher incidence of respiratory cancer reported in copper smelters is due to arsenic contained in the ore.
