3. HAZARDS
IDENTIFICATION |
EMERGENCY OVERVIEW:
CAUTION: Inhalation of mist or dust may be harmful. Avoid
repeated or prolonged breathing of spray mist or dusts. Keep container closed when not in
use. Use with adequate ventilation.
|
TARGET ORGANS:
Eyes, Skin, Respiratory Tract (nose & throat)
EYE IRRITATION:
May cause mild, short-lasting irritation.
SKIN IRRITATION:
May cause mild, short-lasting irritation.
RESPIRATORY TRACT (nose & throat) IRRITATION:
May cause irritation to the respiratory tract and lungs if
dust is generated and inhaled. |
HAZARD CLASSIFICATION
The International Agency for Research on Cancer (IARC)
has classified amorphous silica as a Group 3 substance, not classifiable as to its
carcinogenicity to humans.
The Hazardous Materials Identification System (HMIS)
–
| Health 1 |
Flammability 0 |
Reactivity 0 |
Personal Protection Index: B |
FIRST AID PROCEDURES
EYE IRRITATION:
If eyes become irritated, flush immediately with large amounts
of lukewarm water for at least 15 minutes. Eyelids should be held away from the eyeball to
ensure thorough rinsing. Do not rub eyes. Get medical attention if irritation persists.
SKIN IRRITATION:
If skin becomes irritated, rinse with large amounts of
lukewarm water for at least 15 minutes. Get medical attention if irritation persists.
RESPIRATORY TRACT (nose & throat) IRRITATION:
If respiratory tract irritation develops, move the person to a
dust free location. Get medical attention if the irritation continues. See Section 8 for
additional measures to reduce or eliminate exposure.
NOTE TO PHYSICIANS:
Based on the individual's reactions, the physician's judgment
should be used to control symptoms and clinical condition.

SPILL PROCEDURES
Small liquid spills: Contain with absorbent material, such as
clay, soil or any commercially available absorbent. Shovel reclaimed liquid and absorbent
into recovery or salvage drums for disposal.
Large liquid spills: Dike to prevent further movement and
reclaim into recovery or salvage drums or tank truck for disposal.

Water
Silica (amorphous) |
None established.
20 mppcf or 80 mg/m³ / % SiO2 |
None established
None established |
OTHER OCCUPATIONAL EXPOSURE LEVELS (OEL)
Non-regulatory OEL examples include: ACGIH TLVs (TWAs): Water -- None
established. Silica (amorphous) -- 10 mg/m³.
PERSONAL PROTECTION EQUIPMENT
Respiratory Protection:
Respiratory protection is not normally needed since the
volatility and toxicity are low. If significant mists or aerosols are generated,
respiratory protection, pursuant to the requirements of OSHA Standards 29 CFR 1910.134 and
29 CFR 1926.103, is recommended.
Ventilation:
General ventilation is recommended.
Protective Equipment:
Use impermeable gloves and chemical splash goggles when
attaching feeding equipment, doing maintenance or handling product.
The availability of an eye wash fountain and safety shower is
recommended.
If clothing is soiled, remove clothing and thoroughly wash the
affected area. Launder soiled clothing before reuse.

11.
TOXICOLOGICAL INFORMATION |
The International Agency for Research on Cancer (IARC), has
concluded that amorphous silica is "not classifiable as to its carcinogenicity to
humans (Group 3)" based on "inadequate evidence in humans for the
carcinogenicity of amorphous silica" and "inadequate evidence in experimental
animals for the carcinogenicity of synthetic amorphous silica" (IARC Monograph 68,
June 1997, p. 210-211).
EPIDEMIOLOGY:
IARC noted that "very little epidemiological evidence was
available" for amorphous silica. In evaluating the results of three community-based
case-control studies, IARC concluded that "no association was detected for
mesothelioma with biogenic amorphous silica fibres." (IARC Monograph 68, June 1997,
p. 208).
TOXICOLOGY:
A food-grade micronized synthetic amorphous silica was tested
by oral administration to mice and rats. No increased incidence of tumors was seen. In
another study in rats, using intrapleural implantation of two different preparations of
synthetic amorphous silica, no increased incidence of tumors were observed (IARC Monograph
68, June 1997, p. 209).

13. DISPOSAL
CONSIDERATIONS |
DISPOSAL
This product, as manufactured, is not classified as a
hazardous waste according to Federal regulations (40 CFR 261). Any processing, use,
alteration or chemical additions to the product, as purchased, may alter the disposal
requirements. Under Federal regulations, it is the waste generator's responsibility to
properly characterize a waste material, to determine if it is a "hazardous"
waste. Check local, regional, state or provincial regulations to identify all applicable
disposal requirements.
As a non-hazardous liquid waste, it should be solidified with
stabilizing agents (such as sand, fly ash, or cement) so that no free liquid remains prior
to disposal.
