Potential Health Effects
----------------------------------
Inhalation:
Inhalation of dust may irritate the respiratory tract due to corrosive
nature. Symptoms include sore throat, coughing, and shortness of breath.
Symptoms of lung edema may be delayed and serious cases may be fatal.
Ingestion:
Corrosive. May cause burning pain in mouth and esophagus and burns to
mucous membranes. May produce gastrointestinal distress with abdominal
pain, nausea, vomiting and diarrhea.
Skin Contact:
Corrosive. May cause irritation or burns with redness and pain.
Eye Contact:
Corrosive. Eye contact may cause severe pain, blurred vision, and tissue
damage.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems 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. Call a physician.
Ingestion:
Do NOT induce vomiting. Give large amounts of water. Never give anything by
mouth to an unconscious person. Call a physician.
Skin Contact:
In case of contact, wipe off excess material from skin then immediately
flush skin with plenty of water for at least 15 minutes. Remove
contaminated clothing and shoes. Wash clothing before reuse. Call a
physician.
Eye Contact:
In case of contact, hold eyelids apart and flush eyes with plenty of water
for at least 15 minutes. Call a physician.
5. Fire Fighting Measures
Fire:
Not combustible, but may react slowly in a fire.
Explosion:
Not explosive but violent reaction will result if streams of water contact
large quantities.
Fire Extinguishing Media:
Extinguish fires in adjacent materials with dry chemical or foam. Do not
use water.
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
Ventilate area of leak or spill. Wear appropriate personal protective
equipment as specified in Section 8. Spills: Pick up and place in a
suitable container for reclamation or disposal, using a method that does
not generate dust. Do not spray spills with water. Structural fire fighters
clothing is not adequate protection for this material. After removing
material, neutralize residue with soda ash, lime or limestone. Do not flush
waste to sewers or open waterways. A delay in cleanup may allow absorption
of moisture from the atmosphere and may increase the difficulty of cleaning
up the spill area.
7. Handling and Storage
Keep in a tightly closed container. Protect from physical damage. Store in
a cool, dry, ventilated area away from sources of heat, moisture and
incompatibilities. Storage in sprinklered buildings is not recommended.
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.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-ACGIH Threshold Limit Value (TLV):
2 mg/m3 (TWA) soluble salts as Al
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 respirator with an acid gas
cartridge and dust/mist filter 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 respirator with an acid gas cartridge and dust/mist filter 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. Maintain eye wash fountain and quick-drench
facilities in work area.

13. Disposal Considerations
Whatever cannot be saved for recovery or recycling should be managed in an
appropriate and approved waste facility. Although not a listed RCRA
hazardous waste, this material may exhibit one or more characteristics of a
hazardous waste and require appropriate analysis to determine specific
disposal requirements. Processing, use or contamination of this product may
change the waste management options. State and local disposal regulations
may differ from federal disposal regulations.
Dispose of container and unused contents in accordance with federal, state
and local requirements.
