First-aid measures
In case of inhalation of, ingestion of, or skin contact with the dust or fumes generated during processing of the product, immediately
give first aid described below, and then seek medical attention or treatment if necessary.
・ Inhalation: Move victim to fresh air and keep at rest in position comfortable for breathing.
・ Skin contact: Wash skin immediately with plenty of water and soap.
・ Eye contact: Rinse carefully with water for several minutes. In case of using contact lenses, remove them if easy to do so. Continue
rinsing.
・ Ingestion: Rinse mouth out thoroughly with water.
・ Others: In case of skin wound such as a cut from edge or chips of the product, keep wound clean. If skin becomes burned by arcs,
etc., cool with water.

5.

Fire-fighting measures
When heated in air to a temperature near its melting point, magnesium alloys ignite and burn with a white flame. Smother burningmagnesium by covering with an extinguishing powder approved for use on magnesium fires. Consult national fire protection
association standards for other extinguishing media which may be applicable to certain operations such as foundries or heat treat
furnaces.
・ Suitable extinguishing media: Class D fire extinguisher or smother with dry sand etc.
・ Unsuitable extinguishing media: DO NOT use carbon dioxide or halogenated extinguishing agents. DO NOT use water or foam.

6.

Accidental release measures

No available data to exposure prevention and protective measures for the product in solid state. However, with operations such as
welding, sawing, brazing, grinding, machining etc. that might case dust/fume, follow the procedures shown below.
6.1 Personal precautions, protective equipment, and emergency procedures
Provide adequate ventilation. Wear appropriate protective equipment to prevent inhalation of or eye contact with dust or fumes. See
section 8.
6.2 Environmental precautions
Promptly collect dust generated by processing such as cutting and polishing. Prevent their leakage.
6.3 Methods and materials for containment and cleaning up
Contaminated packages must be disposed of as waste according to section 13.

7.

Handling and Storage

7.1 Precautions for safe handling
Wear appropriate protective equipment in case of generating dust or fumes during welding, weld cutting or grinding. Moreover, besure to provide local or general ventilation system.
Promptly collect processing waste with a dust collector, store the collected processing waste in a steel container, and treat the waste
by chemical treatment, etc.
For heavy weights, call for precautions in handling, against toppling, rolling and package-collapsing. Cut-ends and cutting chips withburr may be injurious. Fumes from welding and fine particles may cause fire injury. When cutting bundling and packaging hoops(bands), be careful about bouncing hoops and hoop-tips. Particularly with coils, be careful about their leading ends which, whenunbundled, might spring up ward.
7.2 Conditions for safe storage, including any compatibilities
Avoid contact with water leakage, acid, alkali or substances containing them. Avoid environment with high temperature and highhumidity. Pack them with sheets or covers to prevent products from getting rusty/rain water infiltrations, if needed.

8.

Exposure Controls/ Personal Protection
No available data to exposure prevention and protective measures for the product in solid state. However, with operations such as
welding, sawing, brazing, grinding, machining etc. that might case dust/fume, follow the exposure control/personal protection
procedures shown below.

10. Stability and reactivity
10.1 Reactivity/Chemical stability: Stable and non-reactive under general condition.
10.2 Possibility of hazardous reactions:・ Magnesium reacts with carbon dioxide, sulfur dioxide, and moisture in the atmosphere to form oxides, sulfides, and hydroxide layers.
・ Molten magnesium burns slowly emitting a flash of light when it reacts with oxygen in the atmosphere to form white magnesium oxide(MgO).
・ Magnesium reacts with nitrogen in the atmosphere to form brown magnesium nitride (Mg3N2). Magnesium nitride will react violently
with water to generate high heat. The amount of heat generated per mole corresponds to that generated per one mole of magnesium.
・ When modest amount of water is exposed to the burning magnesium, water is decomposed, hydrogen and oxygen are generated,
and it causes an explosion and accelerates the combustion of magnesium.
・ Chips and fine dust from magnesium, including modest amount of water, are easily ignited by open flames, and burn strongly when
exposed to the hydrogen and oxygen generated by the decomposition of water.
・ If the iron oxide (e.g. oxidized scale resulting from iron pod) contacts the molten magnesium, a violent reaction (thermite reaction)
occurs to form iron and magnesium fluoride.
・ If the iron fluoride (reactant of iron and rich gas of sulfur hexafluoride) contacts the molten magnesium, a violent reaction (thermite
reaction) occurs to form iron and magnesium fluoride.
・ Magnesium is generally stable to water, but reacts with high temperature water or an aqueous solution containing chloride to form
magnesium hydroxide (Mg(OH)2) while generating hydrogen gas.
・ Magnesium reacts violently with acids and simultaneously generates hydrogen gas. However, it is stable in a concentratedhydrofluoric acid or chromic acid aqueous solution because of forming a passive film.
For details, see “Safety guidelines for Handling” on the website of the Japan Magnesium Association. (Japanese only)
10.3 Conditions to be avoided: Keep away from environments of humidity, water, acid, etc.
10.4 Incompatible materials: Strong oxidizing agent, acid, etc.
10.5 Hazardous decomposition products: Inter-metallic compounds in fume at welding/fusing may exist.
