Potential Health Effects
----------------------------------

Inhalation:
Inhalation of large amounts of this fine dust may lead to pulmonary edema. May cause irritation to the upper respiratory tract. Tickling cough is a common symptom.
Ingestion:
Large doses may cause gastric irritation, nausea, and diarrhea.
Skin Contact:
May cause irritation.
Eye Contact:
May cause redness or irritation of eyes.
Chronic Exposure:
Prolonged inhalation of dust is associated with respiratory effects. Long term excessive exposures to talc may cause Talcosis, a pulmonary fibrosis which may in turn lead to severe and permanent damage to the lung. Crystalline silica: Chronic inhalation of dust can produce silicosis, a disease of the lungs. Cardiopulmonary impairment may occur. Chronic inhalation of crystalline silica is a lung cancer hazard.
Aggravation of Pre-existing Conditions:
No information found.

4. First Aid Measures

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.

5. Fire Fighting Measures

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.

6. Accidental Release Measures

Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal. Talc accumulations on walking surfaces will cause very slippery conditions.



7. Handling and Storage

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

Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL):
20 mppcf for talc containing no asbestos
-ACGIH Threshold Limit Value (TLV):
2 mg/m3 (TWA) respirable dust for talc containing no asbestos

OSHA PERMISSIBLE LIMITS (PELs):
- For silica, amorphous, including natural diatomaceous earth (112926-00-8):
( 80 mg/m3) / (%SiO2), (TWA).
- For silica, crystalline, quartz (14808-60-7):
(30mg/m3)/(%SiO2 + 2), (TWA), total dust;
(10 mg/m3)/(%SiO2 + 2), (TWA), respirable fraction;
where "%SiO2" is the percentage of crystalline silica
determined by airborne samples, as defined by
29 CFR 1910.1000, Z-3.
- For silica, crystalline, tridymite (15468-32-3) or cristobalite (14464-46-1):
Use one-half of the quartz exposure limits.

ACGIH THRESHOLD LIMIT VALUES:
- For silica, crystalline, quartz (14808-60-7):
0.025 mg/m3 (TWA), respirable fraction, A2 - Suspected Human Carcinogen.
- For silica, crystalline, cristobalite (14464-46-1):
0.025 mg/m3 (TWA), respirable 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. Where respirators are required, you must have a written program covering the basic requirements in the OSHA respirator standard. These include training, fit testing, medical approval, cleaning, maintenance, cartridge change schedules, etc. See 29CFR1910.134 for details.
Skin Protection:
Wear protective gloves and clean body-covering clothing.
Eye Protection:
Safety glasses. Maintain eye wash fountain and quick-drench facilities in work area.
