1.Composition/Information on Ingredients Ingredient CAS No Percent Hazardous --------------------- ------------ ------------ --------- Magnesium Sulfate Hpetahydrate10034-99-898- 99.5%No
2.Hazards Identification Emergency Overview -------------------------- CAUTION!MAY BE HARMFUL IF SWALLOWED.
SAF-T-DATA(tm) Ratings (Provided here for your convenience) ------------------------------------------------------------------------------------------------- Health Rating: 1 - Slight Flammability Rating: 0 - None Reactivity Rating: 1 - Slight Contact Rating: 1 - Slight Lab Protective Equip: GOGGLES; LAB COAT; PROPER GLOVES Storage Color Code: Green (General Storage) ---------------------------------------------------------------------------------------------------- Potential Health Effects ---------------------------------- 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.
3.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.
4.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.
5.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 protective gloves and clean body-covering clothing. Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
