Magnesium

Magnesium is a lightweight alkaline earth metal with the chemical symbol Mg and atomic number 12. It appears as a silvery-white metal that is highly reactive and flammable. With a molecular weight of 24.305 g/mol, magnesium is the eighth most abundant element in Earth's crust and plays essential roles in both biological processes and industrial applications.

Magnesium is a silver-white metallic solid at room temperature with a relatively low density of 1.74 g/cm³. It has a melting point of 650°C and boiling point of 1090°C. The metal is odorless and reacts readily with water, especially when heated, producing hydrogen gas. It burns with a brilliant white flame and is highly flammable in powder or ribbon form.

Magnesium is widely used in aerospace and automotive industries for lightweight alloys, reducing vehicle weight and fuel consumption. It serves as a deoxidizer in steel production, a reducing agent in metallurgy, and in pyrotechnics for its bright white flame. Other applications include die-casting, chemical synthesis, and as an essential component in fertilizers and dietary supplements.

Magnesium requires careful handling due to its flammable and water-reactive properties classified as Danger. Use appropriate personal protective equipment including safety goggles, protective gloves, and flame-resistant clothing. Work in well-ventilated areas away from heat sources, sparks, and moisture. Keep dry sand or specialized Class D fire extinguishers nearby, never use water on magnesium fires.

Magnesium must be stored in a cool, dry place away from moisture, heat sources, and incompatible materials. Use airtight containers with desiccants to prevent water contact, which can cause dangerous reactions. Store separately from oxidizing agents, acids, and halogenated compounds. Ensure storage areas have adequate ventilation and appropriate fire suppression systems designed for metal fires.

In case of skin contact with magnesium powder, brush off gently and wash thoroughly with water. For eye contact, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek medical help. Never use water on magnesium fires.

Magnesium waste must be disposed of according to local and national hazardous waste regulations. Contact licensed waste disposal companies experienced in handling flammable metals. Small quantities can sometimes be neutralized through controlled oxidation, but this requires professional expertise. Never dispose of magnesium in regular waste streams or pour down drains due to its reactive nature.

Magnesium is classified under ADR Class 4.3 (substances which, in contact with water, emit flammable gases), Packing Group II. It requires specialized packaging in moisture-proof containers with appropriate hazard labels and documentation. Transport vehicles must comply with ADR regulations, including proper ventilation and emergency equipment. Professional logistics companies experienced in dangerous goods handling are recommended.

Magnesium is regulated under CLP regulation with hazard classifications including Flammable Solid Category 1, Self-heating Category 1, and Water-reactive Category 2. It requires GHS02 flame pictogram and 'Danger' signal word on labels. REACH registration applies for commercial use. Transportation follows ADR dangerous goods regulations, and workplace exposure limits may apply under occupational safety legislation.
