Potential Health Effects
----------------------------------
This product contains synthetic amorphous silica, not to be confused with
crystalline silica such as quartz, cristobalite or tridymite or with
diatomaceous earth or other naturally occurring forms of amorphous silica
that frequently contain crystalline forms. NOTE: The hazard information
listed is for the material bonded to the flexible strip.
Inhalation:
May cause dryness and irritation to mucous membranes, nose, and throat.
Symptoms may include coughing, sore throat, and wheezing.
Ingestion:
No adverse effects expected.
Skin Contact:
May cause irritation with dryness and abrasion.
Eye Contact:
May cause irritation, redness and pain.
Chronic Exposure:
Repeated exposure may cause symptoms similar to those listed for acute
effects. Synthetic amorphous silica does not produce silicosis.
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:
Immediately flush skin with plenty of soap and water for at least 15
minutes. Remove contaminated clothing and shoes. Wash clothing before reuse.
Thoroughly clean shoes before reuse. Get medical attention 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.
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. 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:
Silica (synthetic, amorphous):
- OSHA Permissible Exposure Limit (PEL) -
80/(%SiO2) mg/m3 (TWA) for amorphous silica, including natural diatomaceous
earth.
- ACGIH Threshold Limit Value (TLV) -
10 mg/m3 (TWA) for amorphous precipitated silica and amorphous silica gel.
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):
Not expected to require personal respirator usage. 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:
Not expected to require eye protection. Maintain eye wash fountain and
quick-drench facilities in work area.
