6. ACCIDENTAL RELEASE MEASURES
Personal protection: Wear chemical goggles, body-covering protective clothing, chemical
resistant gloves, and rubber boots, NIOSH-approved dust respirator
where dust occurs. See section 8.
Environmental Hazards: Sinks and mixes with water. High pH of this material is harmful to
aquatic life, see Section 12.
Small spill cleanup: Carefully shovel or sweep up spilled material and place in suitable
container. Avoid generating dust. Use appropriate Personal Protective
Equipment (PPE). See section 8.
Large spill cleanup: Keep unnecessary people away; isolate hazard area and deny entry. Do
not touch or walk through spilled material. Carefully shovel or sweep up
spilled material and place in suitable container. Avoid generating dust.
Use appropriate Personal Protective Equipment (PPE). See section 8. In
case of contact with water, prevent runoff from entering into storm
sewers and ditches which lead to natural waterways. Neutralize
contaminated area and flush with large quantities of water. Comply with
applicable environmental regulations.
CERCLA RQ (US): There is no CERCLA Reportable Quantity for this material. If a spill

11. TOXICOLOGICAL INFORMATION
Acute Data: When tested for primary irritation potential, a similar material caused severe
irritation to the eyes and was slightly irritating to the skin. Human experience
indicates that irritation occurs when sodium silicates get on clothes at the collar,
cuffs or other areas where contact and abrasion may occur.
The acute oral toxicity of this product has not been tested. When sodium silicates
were tested on a 100% solids basis, their single dose acute oral LD50 in rats ranged
from 1500 mg/kg to 3200 mg/kg. The acute oral lethality resulted from
nonspecific causes. This product contains approximately 82.5% sodium silicate.
Subchronic Data: In a study of rats fed sodium silicate in drinking water for three months, at 200,
600 and 1800 ppm, changes were reported in the blood chemistry of some animals,
but no specific changes to the organs of the animals due to sodium silicate
administration were observed in any of the dosage groups. Another study
reported adverse effects to the kidneys of dogs fed sodium silicate in their diet at
2.4g/kg/day for 4 weeks, whereas rats fed the same dosage did not develop any
treatment-related effects. Decreased numbers of births and survival to weaning
was reported for rats fed sodium silicate in their drinking water at 600 and 1200
ppm.
Special Studies: Frequent ingestion over extended periods of time of gram quantities of silicates
is associated with the formation of kidney stones and other siliceous urinary
calculi in humans.
Mutagenicity: Sodium silicate was not mutagenic to the bacterium E. Coli when
tested in a mutagenicity bioassay.
Carcinogenicity: There are no known reports of carcinogenicity of sodium
silicates. Sodium silicate is not listed by IARC, NTP or OSHA as a carcinogen.
Sensitization to product: Not applicable
Reproductive toxicity: Not applicable
Teratogenicity: Not applicable
Name of toxicologically synergistic products: Not applicable
12. ECOLOGICAL INFORMATION
Eco toxicity: The following data is reported for sodium silicates on a 100% solids basis: A 96
hour median tolerance for fish (Gambusia affnis) of 2320 ppm; a 96 hour median
tolerance for water fleas (Daphnia magna) of 247 ppm; a 96 hour median
tolerance for snail eggs (Lymnea) of 632 ppm; and a 96 hour median tolerance for
Amphipoda of 160 ppm. This product contains approximately 82.5% sodium
silicate.
Environmental Fate: This material is not persistent in aquatic systems, but its high pH when undiluted
or unneutralized is acutely harmful to aquatic life. Diluted material rapidly
depolymerizes to yield dissolved silica in a form that is indistinguishable from
natural dissolved silica. It does not contribute to BOD. This material does not
bioaccumulate except in species that use silica as a structural material such as
diatoms and siliceous sponges. Where abnormally low natural silica
concentrations exist (less than 0.1 ppm), dissolved silica may be a limiting nutrient
for diatoms and a few other aquatic algal species. However, the addition of excess
dissolved silica over the limiting concentration will not stimulate the growth of
diatom populations; their growth rate is independent of silica concentration once
the limiting concentration is exceeded. Neither silica nor sodium will appreciably
bioconcentrate up the food chain.
Physical/Chemical: Sinks and mixes with water. Only water will evaporate from this material.
