3. HAZARDS IDENTIFICATION
Emergency Overview: Clear to opalescent, colorless, odorless, liquid. Causes
moderate eye irritation, and slight skin irritation and digestive
tract irritation. Spray mist causes irritation to respiratory
tract. Due to high pH of product, release into surface water is
harmful to aquatic life. Noncombustible. Spills are slippery.
Reacts with acids, ammonium salts, reactive metals and some
organics.
Eye contact: Causes moderate irritation to the eyes.
Skin contact: Causes slight irritation to the skin.
Inhalation: Spray mist irritating to respiratory tract.
Ingestion: May cause irritation to mouth, esophagus, and stomach.
Chronic hazards: Possible developmental hazard. Contains lithium that may
adversely affect the developing fetus. Not listed by NTP, IARC
or OSHA as a carcinogen.
Physical hazards: Dries to form glass film which can easily cut skin. Spilled
material is very slippery. Can etch glass if not promptly
removed.
4. FIRST AID MEASURES
Eye: In case of contact, immediately flush eyes with plenty of water for at least
15 minutes. Get medical attention.

Skin: In case of contact, immediately flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical attention.
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical attention.
Ingestion: If swallowed, DO NOT induce vomiting. Get medical attention
immediately. If victim is fully conscious, give a cupful of water. Never
give anything by mouth to an unconscious person.
5. FIRE FIGHTING MEASURES
Flammable limits: This material is noncombustible.
Extinguishing Media: This material is compatible with all extinguishing media.
Hazards to fire-fighters: See Section 3 for information on hazards when this material
is present in the area of a fire.
Fire-fighting equipment: The following protective equipment for fire fighters is
recommended when this material is present in the area of a
fire: chemical goggles, body-covering protective clothing,
chemical resistant gloves, and rubber boots.
6. ACCIDENTAL RELEASE MEASURES
Personal protection: Wear chemical goggles, body-covering protective clothing, chemical
resistant gloves, and rubber boots. See section 8.
Environmental Hazards: Sinks and mixes with water. High pH of this material is harmful to
aquatic life, see Section 12. Only water will evaporate from a spill of this
material.
Small spill cleanup: Contain and/or absorb spill with inert material (e.g. sand, vermiculite),
then place in suitable container. Do not flush to sewer or allow to enter
waterways. Use appropriate Personal Protective Equipment (PPE).
Large spill cleanup: Keep unnecessary people away; isolate hazard area and deny entry. Do
not touch or walk through spilled material. Stop leak if you can do so
without risk. Prevent runoff from entering into storm sewers and ditches
which lead to natural waterways. Isolate, dike and store discharged
material, if possible. Use sand or earth to contain spilled material.
CERCLA RQ: There is no CERCLA Reportable Quantity for this material. If a spill
goes off site, notification of state and local authorities is recommended.
7. HANDLING AND STORAGE
Handling: Avoid contact with eyes, skin and clothing. Avoid breathing spray mist.
Keep container closed. Promptly clean residue from closures with cloth
dampened with water. Promptly clean up spills.
Storage: Keep containers closed. Store in clean plastic containers. Separate from
acids, reactive metals, and ammonium salts. Recommended storage
temperature 15潞-60潞 C (59潞-140潞 F) . Do not store in aluminum, steel,
fiberglass, copper, brass, zinc or galvanized containers.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering controls: Use with adequate ventilation. Keep containers closed. Safety shower
and eyewash fountain should be within direct access.
Respiratory protection: Use a NIOSH-approved dust and mist respirator where spray mist
occurs. Observe OSHA regulations for respirator use (29 C.F.R.
搂1910.134)
Skin protection: Wear body-covering protective clothing and gloves.
Eye protection: Wear chemical goggles.
9. PHYSICAL AND CHEMICAL PROPERTIES
Appearance: Liquid.
Color: Clear to opalescent white.
Odor: Odorless or musty odor.
pH: Approximately 12
1.26 g/cm3 (20潞C); 30潞 B茅; 10.5 lbs/gal
Density:
Solubility in water: Miscible.
10. STABILITY AND REACTIVITY
Stability: This material is stable under all conditions of use and storage.
Conditions to avoid: None.
Materials to avoid: Gels and generates heat when mixed with acid. Absorbs carbon dioxide
on exposure to air. May react with ammonium salts resulting in
evolution of ammonia gas. Flammable hydrogen gas may be produced on
contact with aluminum, tin, lead, and zinc.
Hazardous decomposition
products: Hydrogen.
11. TOXICOLOGICAL INFORMATION
Acute Data: When tested for primary irritation potential a similar material caused
moderate irritation to the eyes and slight irritation to the skin. Human
experience confirms that irritation occurs when potassium silicates get on
clothes at the collar, cuffs or other areas where abrasion may occur.
The acute oral toxicity of this product has not been tested. When
chemically similar 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 30% potassium silicate. Other soluble
lithium compounds have acute oral toxicity (LD50 values) in the range 500
mg/kg to 2100 mg/kg on a 100% basis. This product contains
approximately 5% lithium silicate.
Subchronic Data: The subchronic toxicity of this material has not been tested. Repeated
ingestion or ingestion of large doses of soluble lithium compounds is
reported to cause temporary mental function impairment.
Special Studies: The mutagenic potential of this material has not been tested. Chemically
similar sodium silicate was not mutagenic to the bacterium E. Coli when
tested in a mutagenicity bioassay. Repeated ingestion or ingestion of

large doses of soluble lithium compounds during pregnancy is reported to
cause fetal abnormalities. Frequent ingestion over extended periods of
time of gram quantities of silicates is associated with the formation
kidney stones and other siliceous urinary calculi in humans. No
ingredient of this product is listed by IARC, NTP or OSHA as a
carcinogen.
12. ECOLOGICAL INFORMATION
Ecotoxicity: The ecotoxicity of this material has not been tested.
Environmental Fate: This material is not persistent in aquatic systems, but its high pH when
undiluted or unneutralized is acutely harmful to aquatic life. It does not
contribute to BOD.
Physical/Chemical: Sinks and mixes with water. Only water will evaporate from this
material.
13. DISPOSAL CONSIDERATIONS
Classification: Disposed material is not a RCRA Hazardous waste.
Disposal Method: Dispose in accordance with federal, state and local regulations and
permits.
14. TRANSPORT INFORMATION
DOT UN Status: This material is not regulated hazardous material for transportation.
15. REGULATORY INFORMATION
CERCLA: No CERCLA Reportable Quantity has been established for this material.
SARA TITLE III: Not an Extremely Hazardous Substance under 搂302. Not a Toxic
Chemical under 搂313. Hazard Categories under 搂搂311/312: Acute
TSCA: All ingredients of this material are listed on the TSCA inventory.
