CAS No.: 7778-18-9
Molecular Weight: 136.14
Chemical Formula: CaSO4
Product Codes: 31132
Ingredient CAS No Percent Hazardous
--------------------------------------- ------------ ------------ ---------
Calcium Sulfate (anhydrous) 7778-18-9 98 - 100% Yes
Inhalation: Causes irritation to the respiratory tract. Symptoms may
include coughing, shortness of breath.
Ingestion: May cause obstruction in stomach, as it hardens with moisture.
Symptoms include stomach pain, distress.
Skin Contact: Causes irritation, redness, pain.
Eye Contact: Causes irritation, redness, and pain.
Chronic Exposure: No information found.
Aggravation of Pre-existing Conditions: No information found.
Inhalation: Remove to fresh air. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion: Induce vomiting immediately as directed by medical personnel.
Never give anything by mouth to an unconscious person. Get medical attention.
Skin Contact: Immediately flush skin with plenty of water for at least 15
minutes. Remove contaminated clothing and shoes. Get medical attention. Wash
clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact: Immediately flush eyes with plenty of water for at least 15
minutes, lifting lower and upper eyelids occasionally. Get medical attention
immediately.
Note to Physician: Drinking glycerin, gelatin solutions, or large volumes
of water may delay the hardening of calcium sulfate in the stomach. Surgical
relief of obstruction, particularly at the pylorus, may be necessary.
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
-ACGIH Threshold Limit Value (TLV):10 mg/m3 (TWA) inhalable fraction
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: 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.
