3. Hazards Identification
Emergency Overview
CAUTION! MAY BE HARMFUL IF SWALLOWED.
Potential Acute Health Effects:
Hazardous in case of ingestion.
Slightly hazardous in case of skin contact (irritant), of eye contact
(irritant), of inhalation.
Potential Chronic Health
Effects:
CARCINOGENIC EFFECTS: Not
available.
MUTAGENIC EFFECTS: Not available.
TERATOGENIC EFFECTS:
Not
available.
DEVELOPMENTAL TOXICITY: Not
available.
Repeated or prolonged exposure is
not known to aggravate medical condition.
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: Magnesium Sulfate is not flammable.
Explosion:
It is 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.
6. Accidental Release Measures
Small
Spill: Use
appropriate tools to put the spilled solid in a convenient waste disposal
container. Finish cleaning by spreading
water on the contaminated surface and dispose of according to local and regional
authority requirements.
Large Spill: Use a shovel to put the material into
a convenient waste disposal container. Finish cleaning by spreading water on
the contaminated surface and allow to evacuate through the sanitary system.
7. Handling and Storage
Keep Magnesium Sulfate in a tightly closed
container, stored in a cool, dry, ventilated area. Protect against physical
damage. Isolate from incompatible substances. Containers 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,
glycerin, 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.
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.
