Potential Health Effects
Inhalation:
A strong alkaline irritant. Inhalation can cause
severe irritation of mucous membranes and upper respiratory
tract. Symptoms may include burning sensation, coughing,
wheezing, laryngitis, shortness of breath, headache, nausea and
vomiting. High concentrations may cause lung damage.
Ingestion:
A strong alkaline irritant. Causes irritation to
the gastrointestinal tract. Symptoms may include nausea,
vomiting and diarrhea. Solid sodium silicate: Alkaline corrosive
ingestion may produce burns to the lips, tongue, oral mucosa,
upper airway, esophagus and occasionally stomach.
Skin Contact:
A strong alkaline irritant. Causes severe
irritation. Symptoms include redness, itching and pain. Dries to
form a glass film which can cut skin. Solid sodium silicate:
Dermal contact with alkaline corrosives may produce pain,
redness, severe irritation or full thickness burns.
Eye Contact:
A strong alkaline irritant. Alkaline eye
exposures produce severe irritation with effects similar to
those of dilute caustics. Inflammation or burns with possible
damage to the eye tissues can occur together with tearing and
considerable pain.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or
impaired respiratory function may be more susceptible to the
effects of the substance.
4. First Aid Measures
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. Give large
quantities of water. Never give anything by mouth to an
unconscious person. Get medical attention immediately.
Skin Contact:
Immediately flush skin with plenty of water for
at least 15 minutes. Remove contaminated clothing and shoes. Get
medical attention. Wash clothing before reuse. Thoroughly clean
shoes before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for
at least 15 minutes, lifting lower and upper eyelids
occasionally. Get medical attention immediately.
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:
In the event of a fire, wear full protective
clothing and NIOSH-approved self-contained breathing apparatus
with full facepiece operated in the pressure demand or other
positive pressure mode.
6. Accidental Release Measures
Caution! Floor and other surfaces may be
slippery. Ventilate area of leak or spill. Wear appropriate
personal protective equipment as specified in Section 8. Contain
and recover liquid when possible. Collect liquid in an
appropriate container or absorb with an inert material (e. g.,
vermiculite, dry sand, earth), and place in a chemical waste
container. Do not use combustible materials, such as saw dust.
Do not flush to sewer!
7. Handling and Storage
Keep in a tightly closed container, stored in a
cool, dry, ventilated area. Protect against physical damage.
Isolate from incompatible substances. Containers of this
material may be hazardous when empty since they retain product
residues (vapors, liquid); observe all warnings and precautions
listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
Amorphous Silica, including natural diatomaceous
earth:
- OSHA Permissible Exposure Limit (PEL):
(80 mg/m3) / (%SiO2) (TWA).
- ACGIH Threshold Limit Value (TLV):
10 mg/m3 (TWA) inhalable particulate;
3 mg/m3 (TWA) respirable particulate.
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):
If the exposure limit is exceeded, a half-face
dust/mist respirator 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 dust/mist respirator 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. 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 impervious protective clothing, including
boots, gloves, lab coat, apron or coveralls, as appropriate, to
prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face
shield where splashing is possible. Maintain eye wash fountain
and quick-drench facilities in work area.
