Copper

Copper is a metallic chemical element with the symbol Cu and CAS number 7440-50-8. It is a reddish-brown transition metal known for its excellent electrical and thermal conductivity properties. With a molecular weight of 63.55 g/mol, copper is one of the few metals that occurs naturally in its pure form and has been used by humans for thousands of years in various applications.

Copper is a solid metal at room temperature with a distinctive reddish-brown color and metallic luster. It has excellent electrical conductivity (second only to silver), high thermal conductivity, and good corrosion resistance. Copper is malleable and ductile, making it easy to shape. It has a melting point of 1,085°C and is insoluble in water but can dissolve in acids and form various compounds.

Copper is used extensively in electrical wiring and electronics due to its superior conductivity. It serves in plumbing systems, heat exchangers, and air conditioning units. Industrial applications include alloy production (brass, bronze), roofing materials, and decorative items. Copper is also used in agriculture as fungicides, in marine applications for hull sheathing, and in various chemical processes as catalysts or raw materials.

Copper should be handled wearing appropriate personal protective equipment including safety gloves, protective clothing, and eye protection. Work in well-ventilated areas to avoid dust inhalation. Avoid generating dust when processing copper materials. Wash hands thoroughly after handling. Given its aquatic toxicity classification (GHS09), prevent environmental release and ensure proper containment during use and processing operations.

Copper should be stored in a dry, well-ventilated area away from moisture to prevent oxidation and corrosion. Keep containers tightly closed and store away from incompatible materials such as strong acids and oxidizing agents. Maintain stable temperatures and protect from physical damage. Ensure storage areas have appropriate spill containment measures due to copper's environmental hazard classification requiring careful handling.

Copper contact typically requires basic first aid measures. For skin contact, wash immediately with soap and water. If copper dust gets in eyes, rinse thoroughly with clean water for at least 15 minutes and seek medical attention if irritation persists. If inhaled, move to fresh air. For ingestion, rinse mouth and seek medical advice. Remove contaminated clothing and wash before reuse.

Copper should be disposed of according to local environmental regulations due to its aquatic toxicity classification. Recycling is the preferred method as copper retains its properties indefinitely. Contact licensed waste management companies for proper disposal. Prevent release into water systems or soil. Small quantities may be accepted by metal recyclers, while industrial amounts require specialized hazardous waste handling procedures.

Copper is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transport purposes. This indicates it requires appropriate packaging and documentation during shipping. Use approved containers and ensure proper labeling with GHS09 pictogram and 'Warning' signal word. Follow ADR regulations for loading, segregation, and transport documentation. Professional carriers experienced with hazardous materials should handle transportation.

Copper is regulated under various European frameworks including CLP regulation for classification and labeling, requiring GHS09 pictogram and 'Warning' signal word due to aquatic toxicity. REACH registration applies for commercial use. It is not currently listed as an SVHC (Substance of Very High Concern). Environmental regulations strictly control copper discharge due to its Aquatic Acute 1 and Aquatic Chronic 1 classifications.

Copper is available through OYSI, a European distributor of chemical products, ensuring reliable supply across European markets. OYSI provides copper meeting regulatory requirements with proper documentation and safety data sheets. As an established chemical distributor, OYSI offers technical support and ensures compliance with European regulations including REACH and CLP requirements for professional and industrial applications.
