Calcium Carbonate 471-34-1 90 - 100% Yes
Inhalation: Excessive concentrations of a nuisance dust may cause
nuisance condition such as coughing, sneezing, and nasal irritation.
Ingestion: Non-toxic.
Skin Contact: Not expected to be a health hazard from skin exposure.
Eye Contact: No information found, but presumed to cause mechanical
irritation.
Chronic Exposure: Excessive oral doses of calcium carbonate may produce
alkalosis and hypercalcemia.
Aggravation of Pre-existing Conditions: No information found.
Inhalation: Remove to fresh air. Get medical
attention for any breathing difficulty.
Ingestion: If large amounts were swallowed, give water to drink and get
medical advice.
Skin Contact: Wash exposed area with soap and water. Get medical advice
if irritation develops.
Eye Contact: Wash thoroughly with running water. Get medical advice if
irritation develops.
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: 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.
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. 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: - 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.
Ventilation System: 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.
Personal Respirators (NIOSH Approved): If the exposure limit is exceeded
and engineering controls are not feasible, a half facepiece 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-facepiece positive-pressure, air-supplied
respirator. WARNING: Air-purifying respirators do not protect workers in
oxygen-deficient atmospheres.
Skin Protection: Gloves and lab coat, apron or coveralls.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain
and quick-drench facilities in work area.
