First-aid measures If breathing is difficult, remove to fresh air and keep at rest in a position comfortable for breathing. If breathing stops, provide artificial respiration. Call a physician if symptoms develop or persist. Inhalation Remove contaminated clothing immediately and wash skin with soap and water. Get medical attention if irritation develops and persists. Wash contaminated clothing before reuse. Skin contact Immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention if irritation develops and persists. Eye contact Rinse mouth. Do not induce vomiting. Call a physician immediately. Never give anything by mouth to a victim who is unconscious or is having convulsions. Ingestion Direct contact with eyes may cause temporary irritation.Most important symptoms/effects, acute and delayed Treat symptomatically.Indication of immediate medical attention and special treatment needed Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves. General information 5. Fire-fighting measures Powder. Foam. Carbon dioxide (CO2). Water spray. Dry sand.Suitable extinguishing media Do not use water jet as an extinguisher, as this will spread the fire.Unsuitable extinguishing media During fire, gases hazardous to health may be formed.Specific hazards arising from the chemical Self-contained breathing apparatus and full protective clothing must be worn in case of fire.Special protective equipment and precautions for firefighters Fire-fighting equipment/instructions Move containers from fire area if you can do so without risk. Use water spray to keep fire-exposed containers cool and to knock down vapors which may result from product decomposition. Prevent fire extinguishing water from contaminating surface water or the ground water system. No unusual fire or explosion hazards noted.General fire hazards 6. Accidental release measures Keep unnecessary personnel away. Keep people away from and upwind of spill/leak. Remove all possible sources of ignition in the surrounding area. Wear appropriate protective equipment and clothing during clean-up. Ensure adequate ventilation. Local authorities should be advised if significant spillages cannot be contained. For personal protection, see section 8 of the SDS. Personal precautions, protective equipment and emergency procedures This material is classified as a water pollutant under the Clean Water Act and should be prevented from contaminating soil or from entering sewage and drainage systems which lead to waterways. Small Spills: Soak up spills with inert solids, such as clay or diatomaceous earth as soon as possible. Sweep up and shovel into suitable containers for disposal. Clean surface thoroughly to remove residual contamination. Never return spills to original containers for re-use. For waste disposal, see section 13 of the SDS. Methods and materials for containment and cleaning up Avoid release to the environment. Prevent further leakage or spillage if safe to do so. Avoid discharge into drains, water courses or onto the ground. Inform appropriate managerial or supervisory personnel of all environmental releases. Environmental precautions 7. Handling and storage Provide adequate ventilation. Avoid prolonged exposure. Wear appropriate personal protective equipment. Wash hands after handling and before eating. Avoid release to the environment. Observe good industrial hygiene practices. Use care in handling/storage. For product usage instructions, please see the product label. Precautions for safe handling Store in original tightly closed container. Store in a well-ventilated place. Store away from incompatible materials (see Section 10 of the SDS).

NIOSH: Pocket Guide to Chemical Hazards ValueComponents FormType TWA 1 mg/m3 Dust and mist.Copper (CAS 7440-50-8) No biological exposure limits noted for the ingredient(s).Biological limit values Good general ventilation (typically 10 air changes per hour) should be used. Ventilation rates should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation, or other engineering controls to maintain airborne levels below recommended exposure limits. If exposure limits have not been established, maintain airborne levels to an acceptable level. Appropriate engineering controls Individual protection measures, such as personal protective equipment Wear safety glasses with side shields (or goggles).Eye/face protection Skin protection Wear protective gloves such as: Rubber (natural, latex).Hand protection Wear suitable protective clothing.Other If engineering controls are not feasible or if exposure exceeds the applicable exposure limits, use a NIOSH-approved cartridge respirator with an organic vapor cartridge. Use a self-contained breathing apparatus in confined spaces and for emergencies. Air monitoring is needed to determine actual employee exposure levels. Respiratory protection Wear appropriate thermal protective clothing, when necessary.Thermal hazards Always observe good personal hygiene measures, such as washing after handling the material and before eating, drinking, and/or smoking. Routinely wash work clothing and protective equipment to remove contaminants. General hygiene considerations 9.
