Potential Health Effects
----------------------------------
Inhalation: Inhalation of dusts or fumes may irritate the respiratory tract and may cause metal fume
fever. Symptoms may include coughing, chest pain, fever, and leukocytosis.
Ingestion: Magnesium metal does not have well-characterized toxicity. May cause abdominal pain and
diarrhea.
Skin Contact: Particles embedded in the skin may cause eruptions. Molten magnesium may cause
serious skin burns.
Eye Contact: High concentrations of dust may cause mechanical irritation. Watching a magnesium fire
can cause eye injury.
Chronic Exposure: No information found.
Aggravation of Pre-existing Conditions: Existing wounds contaminated with magnesium are very slow
to heal.
4. First Aid Measures
Inhalation: Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion: If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give
anything by mouth to an unconscious person. Get medical attention immediately.
Skin Contact: Remove any contaminated clothing. Wash skin with soap or mild detergent and water for
at least 15 minutes. Get medical attention if irritation develops or persists.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower
eyelids occasionally. Get medical attention if irritation persists.
5. Fire Fighting Measures
Fire: Autoignition temperature: 473C (883F)
When heated in air to a temperature near its melting point, magnesium may ignite and burn. Dangerous
in the form of dust or flakes, and when exposed to flame or by violent chemical reaction with oxidizing
agents. Magnesium may react with moisture or acids to evolve hydrogen gas, which is a highly
dangerous fire or explosion hazard. Autoignition temperature is for Magnesium turnings.
Explosion: Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition
source is a potential dust explosion hazard. Minimum explosible concentration 0.030 grams/liter. Water
used on molten magnesium will produce hydrogen gas and may cause an explosion.
Fire Extinguishing Media: Use metal extinguishing powders such as G-1庐 graphite powder, Met-L-X庐
powder, powdered talc, dry graphite, powdered sodium chloride, soda ash, or dry sand. Warning! Do
not use foam, chlorinated products such as Halon庐, carbon dioxide, or water to extinguish magnesium
fires, because dangerous reactions will occur. Use of water on molten magnesium will produce
hydrogen gas and may cause an explosion.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-
contained breathing apparatus with full-facepiece operated in the pressure demand or other positive
pressure mode. Fire fighters should protect their eyes and skin from flying particles. In order to prevent
eye injury, do not look directly at magnesium fires.

6. Accidental Release Measures
Remove all sources of ignition. Ventilate the area of the spill or leak. Wear appropriate personal
protective equipment as specified in Section 8. Collect the spilled material and transfer to a clean, dry
metal covered container for recovery or disposal. Do not use water in the collection process. If the
spilled magnesium has come into contact with water, proceed with caution. Hydrogen gas may be
generated, which may cause a fire or explosion. Evacuate the area, put on fire fighting protective
equipment and proceed as with a metal fire.
7. Handling and Storage
Keep in tightly closed container. Store in a cool, dry, ventilated area. Protect against physical damage.
Store finely divided powder, chips or shavings in detached fire-resistant building, protected from
moisture and away from oxidizers, chlorine, bromine, iodine, acids, and all possible sources of ignition.
Heavier sections may be stored in the open. Storage and use areas should be No Smoking areas. Use
non-sparking type tools and equipment, including explosion proof ventilation. Containers of this
material may be hazardous when empty since they retain product residues (dust, solids); observe all
warnings and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits: None established.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee
exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the
emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please
refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent
edition, for details.
Personal Respirators (NIOSH-Approved): For conditions of use where exposure to dust or mist is
apparent and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better
filters) may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a
NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a
full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect
workers in oxygen-deficient atmospheres.
Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or
coveralls, as appropriate, to prevent skin contact.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of
solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
