Potential Health Effects
----------------------------------
Inhalation:
Inhalation of dust may cause mild irritation to the mucous membranes.
Ingestion:
Since magnesium salts are slowly absorbed, abdominal pain, vomiting and diarrhea may
be the only symptoms. However, if elimination is blocked by bowel blockage or other
reasons, CNS depression, lack of reflexes, hypocalcemia (deficiency of calcium in the
blood) may occur.
Skin Contact:
No adverse effects expected but may cause minor skin irritation.
Eye Contact:
No adverse effects expected but dust may cause mechanical irritation.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
No information found.
4. First Aid Measures
Inhalation:
Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion:
Give several glasses of water to drink to dilute. If large amounts were swallowed, get
medical advice.
Skin Contact:
Remove any contaminated clothing. Wash skin with soap and water for at least 15
minutes. Get medical attention if irritation develops or persists.
Eye Contact:
Wash thoroughly with running water. Get medical advice if irritation develops.
Note to Physician:
IV administration of calcium gluconate will partially reverse the effects of acute
magnesium toxicity. Ventricular support with calcium chloride infusion and mannitol
forced diuresis has also been successful.

5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard.
Explosion:
Not considered to be an explosion hazard. At room temperature the addition of
magnesium chloride to furan-2-peroxycarboxylic acid, will cause the acid to explode.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
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.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective equipment as
specified in Section 8. Spills: Sweep up and containerize for reclamation or disposal.
Vacuuming or wet sweeping may be used to avoid dust dispersal.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against
physical damage. Isolate from incompatible substances. 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 the dust or mist is apparent, a half-face dust/mist
respirator may be worn. 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 protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in
work area.

10. Stability and Reactivity
Stability:
Stable under ordinary conditions of use and storage. By strong ignition is converted into
oxychloride.
Hazardous Decomposition Products:
When heated to decomposition it emits corrosive hydrochloric acid vapor. When heated
to temperatures above 300C (572F) it emits toxic fumes of chlorine gas.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Furan-2-peroxycarboxylic acid. Strong oxidizing agents will release chlorine.
Conditions to Avoid:
Heat, moisture, incompatibles.
