Hazards and Protection.
Storage
Keep in a cool, dry location in a tightly sealed container.
Handling
Always work in a well- ventilated area. Wash hands before eating or smoking.
Protection
Avoid skin contact. Avoid breathing in dust. Wear rubber or PVC gloves, overalls, eye protection and a particulate mask.
Respirators
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Small spills/leaks
Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.
Stability
No data.
Incompatibilities
Strong oxidizing agents.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.

Health.
Exposure limit(s)
OSHA: PEL (8 h TWA): 1 mg/m3.
Exposure effects
Increased temperature may be noted in some cases. Abnormally low blood pressure may occur. Mental status may be depressed.
   Ingestion
Copper carbonate is a moderately toxic chemical via ingestion. Affected areas are kidneys and nervous system. Symptoms are dizziness, gastric pain, vomiting, exhaustion, anaemia, convulsions, coma and death.
   Inhalation
Copper carbonate is a moderately toxic chemical by inhalation. Affected areas are kidneys and nervous system. Symptoms are dizziness, gastric pain, vomiting, exhaustion, anaemia, convulsions, coma and death.
   Skin
Skin exposure can produce in severe irritation, itching, erythema, dermatitis and eczema; systemic toxicity may result.
   Eyes
Copper carbonate can be irritating to the eyes.

First aid
 
   Ingestion
Following ingestion and/or prior to gastric evacuation, immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 15 ml/kg in a child). Vomiting is rapid and spontaneous in most patients following ingestion of copper salts. Ipecac is contraindicated after ingestion of caustic copper salts because of the risk of further injury to the gastrointestinal mucosa and the possibility of severe cns changes.
   Inhalation
If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.
   Skin
Remove contaminated clothing. Wash exposed area with soap and water. If symptoms persist, seek medical attention. Launder clothing before reuse.
   Eyes
If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention.
