What Are the Properties of Magnesium?

British David produced metallic magnesium in 1808 by reducing magnesium oxide with potassium. It is a silver-white light alkaline-earth metal. It is chemically active and can react with acids to form hydrogen. It has certain ductility and heat dissipation properties. Magnesium is widely distributed in nature and is one of the essential elements of the human body.

First aid measures: Skin contact: Remove contaminated clothing and rinse skin thoroughly with soap and water. Seek medical attention if you feel unwell. ^[2]

Eye contact: Raise eyelids and rinse with running water or saline. Seek medical attention if you feel unwell. ^[2]

Inhalation: Quickly leave the scene to fresh air. Keep your airways open. If breathing is difficult, give oxygen. Respiration and heartbeat stopped. Cardiopulmonary resuscitation was performed immediately. Seek medical attention. ^[2]

Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention. ^[2]

Fire-fighting measures: Hazardous characteristics: Flammable, produces intense white light and emits high heat when burned. It reacts violently with water or moisture to emit hydrogen gas, which generates a large amount of heat, causing combustion or explosion. It will react violently with chlorine, bromine, iodine, sulfur, phosphorus, arsenic, and oxidants, and there is danger of burning and explosion. Powder and air can form an explosive mixture. When it reaches a certain concentration, it will explode when it meets Mars. ^[2]

Hazardous combustion products: Magnesium oxide. ^[2]

Fire extinguishing methods: Firefighters must wear air respirators, full-body fireproof and gas-proof clothing, and extinguish fires in the upwind direction. Move the container from the fire to the open space as much as possible. Spray water to keep the fire container cool until the fire is over. Water, foam and carbon dioxide are strictly prohibited. Protect the eyes and skin during rescue to prevent flying particles from burning your body and magnesium rays from damaging your eyesight. ^[2]

Emergency treatment: Isolate leaking contaminated areas and restrict access. Eliminate all ignition sources. Emergency personnel are advised to wear dust masks, dust masks, and antistatic clothing. Do not touch or cross spillage. Cut off the source of the leak if possible. Water treatment is strictly prohibited. Small amount of leakage: Cover the leakage with dry sand or other non-combustible materials, and then cover with plastic cloth to reduce scattering and avoid rain. Powder leakage: Cover the spill with plastic cloth or canvas to reduce scattering and keep dry. Clear under expert guidance. ^[2]

Detection method: flame atomic absorption spectrometry ^[2]

Engineering control: closed operation. Provide safety shower and eyewash equipment. ^[2]

Respiratory system protection: Filter-type dust-proof respirators should be worn during operation. Wear an air respirator if necessary. ^[2]

Eye protection: Wear chemical safety protective glasses. ^[2]

Body protection: Wear antistatic work clothes. ^[2]

Hand protection: Wear general work protective gloves. ^[2]

Other protection: smoking is strictly prohibited at the work site. Maintain good hygiene. ^[2]

Stability: stable ^[2]

Contraindications: Acids, acid chlorides, halogens (chlorine, bromine, iodine), strong oxidants, chlorinated hydrocarbons, water, oxygen, sulfur, phosphorus, arsenic. ^[2]

Avoid contact conditions: humid air. ^[2]

Hazard of polymerization: no polymerization ^[2]

Acute toxicity: Corrosive and irritating. ^[2]

Other harmful effects: The substance may be harmful to the environment. It is recommended not to let it enter the environment. ^[2]

Nature of waste: hazardous waste ^[2]

Disposal methods: Please refer to relevant national and local regulations before disposal. If possible, recycle. ^[2]

Disposal precautions: Please refer to relevant national and local regulations before disposal. ^[2]

Dangerous regulation number: 41502 ^[2]

UN number: 1869 ^[2]

Packaging mark: flammable solid ^[2]

Packaging category: packaging ^[2]

Packaging method: Fully or middle-opened steel drums outside plastic bags or two-layer kraft paper bags (with a thickness of 0.75 mm steel plate and a net weight of 100 kg per barrel); Full-opened or middle-opened steel drums (steel plates with plastic bags or two-layer kraft paper bags outside) 0.5 mm thick, the net weight of each barrel does not exceed 50 kg); metal barrels (cans) or plastic barrels outside grate boxes; threaded glass bottles, iron capped glass bottles, plastic bottles or metal barrels (cans) outside ordinary wooden boxes . ^[2]

Note for transportation: The transportation vehicle should be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment during transportation. The vehicle's exhaust pipe must be equipped with a fire arrester. During transportation, ensure that the container does not leak, collapse, fall, or damage. It is strictly prohibited to mix and transport with oxidants, acids, halogens, chlorinated hydrocarbons, edible chemicals, etc. During transportation, it should be protected from direct sunlight, rain and high temperature. Stay away from fire and heat sources during stopovers. Transportation vehicles and ships must be dry and have good rainproof facilities. The vehicle should be thoroughly cleaned after transportation. Railroad transportation is prohibited. ^[2]

Operational precautions: strengthen local exhaust. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety protective glasses, and antistatic work clothes. Away from fire and heat sources, smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid generating dust. Avoid contact with oxidants, acids, halogens and chlorinated hydrocarbons. Pay particular attention to avoid contact with water. Dispose in nitrogen. Handle with care when handling to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues. ^[2]

Storage Precautions: Store in a cool, dry, well-ventilated special warehouse, away from fire and heat sources. The storage temperature does not exceed 32 ° C, and the relative humidity does not exceed 75%. Packaging is required to be sealed and not in contact with air. It should be stored separately from oxidants, acids, halogens, chlorinated hydrocarbons, etc. Avoid mixed storage. Use explosion-proof lighting and ventilation facilities. Prohibit the use of spark-prone machinery and tools. The storage area should be equipped with suitable materials to contain spills. ^[2]
