Potential Health Effects
REAGENTS, INC.--MSDS--FLORISIL(R), 60-100 MESH PAGE -2-
----------------------------------
Inhalation: May cause dryness and irritation to mucous membranes, nose, and throat.
Ingestion: No adverse effects expected.
Skin Contact: May cause irritation with dryness and abrasion.
Eye Contact: No adverse effects expected but dust may cause mechanical irritation.
Chronic Exposure: Grossly excessive and chronic inhalation of the dust may cause a progressive
chemical pneumonitis, cyanosis, and pulmonary edema. Repeated or prolonged ingestion may contribute
to the production of urinary calculi.
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: Give several glasses of water to drink to dilute. If large amounts were swallowed, 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: Use protective clothing and breathing equipment appropriate for the surrounding
fire.
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.
7. 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.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
- OSHA Permissible Exposure Limit (PEL):
REAGENTS, INC.--MSDS--FLORISIL(R), 60-100 MESH PAGE -3-
15 mg/m 3 total dust, 5 mg/m 3 respirable fraction for nuisance dusts.
- ACGIH Threshold Limit Value (TLV):
10 mg/m 3 total dust containing no asbestos and < 1% crystalline silica for Particulates Not Otherwise
Classified (PNOC).
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): If the exposure limit is exceeded, a half-face dust/mist
respirator 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 dust/mist respirator 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. 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.
