Magnesium Sulfate Anhydrous 7487-88-9 99 - 100% Yes
Inhalation: Dust may be slightly irritating. Sore throat or coughing may
occur.
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.
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.
Fire: Not considered to be a fire hazard.
Explosion: Not considered to be an explosion hazard.
Fire Extinguishing Media: Use any means suitable for extinguishing
surrounding fire.
Special Information: Use protective clothing and breathing equipment
appropriate for the surrounding fire.
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8.
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.
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 protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain
and quick-drench facilities in work area.
Appearance: Transparent crystals, or white powder.
Odor: Odorless.
Solubility: Very soluble in water.
Density: 1.67 g/ml @ 4C
pH: Aqueous solution is neutral or slightly acid.
% Volatiles by volume @ 21C (70F): 0

Evaporation Rate (BuAc=1): No information found.
Stability: Stable under ordinary conditions of use
and storage. Loses some moisture on exposure to dry air at room temperatures.
Hazardous Decomposition Products: Oxides of sulfur and the contained
metal.
Hazardous Polymerization: Will not occur.
Incompatibilities: Ethoxy ethyl alcohols, arsenates, phosphates,
tartrates, lead, barium, strontium, and calcium
Conditions to Avoid: Heat, moisture, incompatibles.
