Magnesium Carbonate 235-192-7 100% 7760-50-1
3.) HAZARDS IDENTIFICATION
Emergency Overview: CAUTION! MAY CAUSE IRRITATION TO EYES AND RESPIRATORY TRACT.
Potential Health Effects: Inhalation: May cause irritation to the respiratory tract. Symptoms may include coughing and shortness of breath. Ingestion: Magnesium carbonate is a food additive and non-toxic unless ingested in very large quantities. May cause diarrhea. Skin Contact: No adverse effects expected. May cause mild irritation and redness. Eye Contact: May cause irritation, redness and pain. 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.
Skin Contact: Wash exposed area with soap and water. Get medical advice if irritation develops.
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.
Ingestion Contact: If large amounts were swallowed, give water to drink and get medical advice.
5.) FIRE FIGHTING MEASURES
Extinguishing Media: Use any means suitable for extinguishing surrounding fire.
Special Fire Fighting Procedures: Not considered to be a fire hazard.
Fire and Explosion Hazzards: Not considered to be an explosion hazard.
Hazardous Combustion Products: No information found.
Protective Measure in Fire: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode.
6.) ACCIDENTAL RELEASE MEASURES
Personal Precaution in Spill: Wear appropriate personal protective equipment as specified in Section 8.
Environment: Ventilate area of leak or spill.
Spill Clean Up: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal.
7.) HANDLING/STORAGE
Usage Precautions:
Usage Descriptions:
Storage Precautions:
Handling Precautions: Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. 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
Protective Equipment: A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. 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.
Process Conditions: - OSHA Permissible Exposure Limit (PEL): 15 mg/m3 total dust, 5 mg/m3 respirable fraction for nuisance dusts. - ACGIH Threshold Limit Value (TLV) for Particulates (insoluble or poorly soluble) Not Otherwise Specified (PNOS): 3 mg/m3 respirable particles and 10 mg/m3 inhalable particles.
Respirators: If the exposure limit is exceeded and engineering controls are not feasible, a half face piece particulate respirator (NIOSH type N95 or better filters) may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest.. A full-face piece particulate respirator (NIOSH type N100 filters) may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest. 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 piece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Protective Gloves: Wear protective gloves.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
Other Protection: Wear clean body-covering clothing.
Hygienic Work Practices: No information found.
9.) PHYSICAL / CHEMICAL PROPERTIES
