HAZARD SUMMARY WORKPLACE EXPOSURE LIMITS * Copper Acetoarsenite can affect you when breathed in The following exposure limits are for inorganic Arsenic and may be absorbed through your skin. (measured as Arsenic): * Skin contact can cause irritation, burning, itching, thickening and color changes. OSHA: The legal airborne permissible exposure limit * Eye contact can cause irritation and burns. (PEL) is 0.01 mg/m3 averaged over an 8-hour * Breathing Copper Acetoarsenite can irritate the nose and workshift. throat and can cause ulcers and a hole in the “bone” dividing the inner nose. NIOSH: The recommended airborne exposure limit is * Repeated exposure can cause poor appetite, a metallic or 0.002 mg/m3, which should not be exceeded garlic taste, nausea, vomiting, stomach pain and diarrhea. during any 15 minute work period. * High or repeated exposure may damage the nerves causing weakness, "pins and needles," and poor coordination in the ACGIH: The recommended airborne exposure limit is arms and legs. 0.01 mg/m3 averaged over an 8-hour workshift. * Copper Acetoarsenite may damage the liver and kidneys. The exposure limits for Copper fume are: IDENTIFICATION Copper Acetoarsenite is an emerald-green crystalline (sand- OSHA: The legal airborne permissible exposure limit like) powder.

REASON FOR CITATION NIOSH: The recommended airborne exposure limit is * Copper Acetoarsenite is on the Hazardous Substance List 0.1 mg/m3 averaged over a 10-hour workshift. because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, DEP, and EPA. ACGIH: The recommended airborne exposure limit is * Definitions are provided on page 5. 0.2 mg/m3 averaged over an 8-hour workshift.

HOW TO DETERMINE IF YOU ARE BEING * The above exposure limits are for air levels only. When EXPOSED skin contact also occurs, you may be overexposed, even The New Jersey Right to Know Act requires most employers though air levels are less than the limits listed above. to label chemicals in the workplace and requires public employers to provide their employees with information and WAYS OF REDUCING EXPOSURE training concerning chemical hazards and controls.

Eating shellfish or fish may elevate Arsenic immediately or shortly after exposure to Copper levels for up to two days. At NIOSH recommended Acetoarsenite: exposure levels, urine Arsenic should not be greater than 50 to 100 micrograms per liter of urine. * Skin contact can cause irritation, burning, itching and rash. * Eye contact can cause irritation and burns.

Exposures in the community, except possibly in cases of fires or spills, are usually much lower than those Industrial Hygiene Information found in the workplace.

In addition, they can help to interpret the results of industrial hygiene survey data.

Medical Evaluation If you think you are becoming sick because of exposure to chemicals at your workplace, you may call personnel at the Department of Health and Senior Services, Occupational Disease and Injury Services, who can help you find the information you need.
