Aluminum

Aluminum is a lightweight metallic element with the chemical formula Al and CAS number 7429-90-5. It is the third most abundant element in the Earth's crust and belongs to the group of reactive metals. With a molecular weight of 26.981538 g/mol, aluminum is classified as a flammable solid and water-reactive substance, making it an important industrial material with specific handling requirements due to its chemical reactivity.

Aluminum is a silvery-white, lightweight metal that appears as a solid at room temperature. It has excellent corrosion resistance due to its natural oxide layer, high thermal and electrical conductivity, and low density. The metal is malleable and ductile, making it easily workable. Aluminum reacts with water under certain conditions and can ignite when in powder form, which explains its classification as a flammable solid and water-reactive material.

Aluminum serves numerous industrial and commercial applications due to its unique properties. It is extensively used in aerospace and automotive industries for lightweight components, construction materials including window frames and roofing, packaging materials such as foil and cans, electrical conductors, and marine applications. Its corrosion resistance and formability make it valuable in manufacturing, while its reflective properties are utilized in mirrors and reflective coatings.

Aluminum requires careful handling due to its flammable and water-reactive properties. Personnel must wear appropriate personal protective equipment including safety glasses, protective gloves, and dust masks when handling powder forms. Work areas should be well-ventilated and free from ignition sources. Avoid contact with water and moisture, especially for fine aluminum powders. Ground all equipment to prevent static electricity buildup, and have appropriate fire suppression systems available.

Aluminum must be stored in dry, well-ventilated areas away from moisture and water sources due to its water-reactive classification. Storage areas should be kept free from ignition sources and incompatible materials such as strong acids and oxidizers. Containers should be tightly sealed and properly labeled with appropriate hazard warnings. Temperature should be controlled, and storage areas must comply with local fire safety regulations for flammable solids.

Immediate first aid measures depend on the type of contact with aluminum. For skin contact, brush off any aluminum particles and wash the affected area with soap and water. In case of eye contact, rinse thoroughly with clean water for at least 15 minutes and seek medical attention. If aluminum dust is inhaled, move the person to fresh air immediately. For ingestion, rinse mouth with water and seek medical advice promptly.

Aluminum disposal must comply with local and national waste management regulations. Clean aluminum can often be recycled through specialized metal recovery facilities, making it an environmentally sustainable option. Contaminated aluminum waste should be classified according to the type of contamination and disposed of through authorized hazardous waste facilities. Never dispose of aluminum in regular municipal waste, and always consult local environmental authorities for specific disposal requirements.

Aluminum is classified under ADR Class 4.1 (flammable solids) Packing Group III for transportation purposes. It requires appropriate packaging that prevents moisture ingress and meets UN specification standards. Vehicles must carry proper placarding and documentation, and drivers need ADR certification. The transport must avoid routes through tunnels with restrictions for dangerous goods, and emergency response information must be readily available during transit.

Aluminum is subject to various European regulations including CLP (Classification, Labelling and Packaging) requirements due to its hazard classification as flammable solid and water-reactive substance. It falls under REACH registration requirements and must display appropriate GHS02 pictograms and danger signal words. The substance is not currently listed as SVHC (Substance of Very High Concern), but users must comply with occupational safety regulations and proper hazard communication standards.
