Storage Color Code: Orange (General Storage)

Potential Health Effects
----------------------------------

Inhalation:
May cause irritation to the respiratory tract.
Symptoms may include coughing and shortness of breath.
Ingestion:

Low single dose toxicity. Ingestion of large amounts may cause nausea,
vomiting and abdominal spasms.
Skin Contact:
May cause
irritation.
Eye Contact:
May cause irritation, redness and
pain.
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. Get medical attention
for any breathing difficulty.
Ingestion:
Give several glasses
of water to drink to dilute. If large amounts were swallowed, get medical
advice.
Skin Contact:
Remove any contaminated clothing. Wash
skin with soap and water for at least 15 minutes. Get medical attention if
irritation develops or persists.
Eye Contact:
Immediately flush
eyes with plenty of water for at least 15 minutes, lifting upper and lower
eyelids occasionally. Get medical attention if irritation persists.

5. Fire Fighting Measures

Fire:
Not considered to be a fire hazard.

Explosion:
Not considered to be an explosion hazard.

Fire Extinguishing Media:
Water, carbon dioxide, or dry
chemical.
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: Sweep up and
containerize for reclamation or disposal. Vacuuming or wet sweeping may be
used to avoid dust dispersal.

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. 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 and
engineering controls are not feasible, a half facepiece particulate respirator
(NIOSH type N95 or better filters) 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 particulate respirator (NIOSH type N100 filters) 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. If
oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present,
use a NIOSH type R or P filter. 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
protective gloves and clean body-covering clothing.
Eye Protection:

Use chemical safety goggles. Maintain eye wash fountain and quick-drench
facilities in work area.
