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.
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> Prolonged exposure to cobalt has been
shown to cause cancer in laboratory animals.
Aggravation of Pre-existing
Conditions:
No information found.

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.

Fire Fighting Measures
Fire:
Not considered to be a fire
hazard.
Explosion;
Not considered to be
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 Measure
Ventilate area of leak or
spill. Wear appropriate personal protective equipment as specified in
Section 8. Spills: Sweep up and containerise for reclamation or
disposal.
Vacuuming or wet sweeping may
be used to avoid dust dispersal. Regulations require reporting spills
and releases to soil, water and air in excess of reportable quantities.

7.
Handling and Storage
Keep in a tightly closed
container, stored in a cool, dry, ventilated area and labelled accordingly. Protect against
physical damage. When pouring into a container of flammable liquid,
ground both containers electrically to prevent a static electric spark.
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.

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.
For Inorganic Cobalt
Compounds:
0.02 mg/m3 (TWA) as Co, A3:
Animal carcinogen.
Ventilation Systems:
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:
If the exposure limit is
exceeded, a half-face dust/mist respirator must be worn suitable for the
exposure limit or the maximum use concentration specified by the
appropriate regulatory agency or respirator supplier, whichever is
lowest.
WARNING: Air-purifying
respirators do not protect workers in oxygen-deficient atmospheres. Respirators must meet the
requirements of European Standard EN149 FF3SL. Suitable for use under
COSHH, CAW, CLAW and IRR.
Skin Protection:
Wear protective gloves and
clean body-covering clothing.
Eye Protection:
Use chemical safety goggles.
Maintain eye wash fountain.
