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 or ribbon.
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® graphite powder, Met-L-X® powder, powdered
talc, dry graphite, powdered sodium chloride, soda ash, or dry sand. Warning!
Do not use foam, chlorinated products such as Halon®, 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.
