Emergency Overview
|
|
CAUTION:
Handling or machining of these products may produce respirable dust
particles. Dust may irritate eyes,
skin respiratory tract. |
|
Inhalation |
Dust may cause irritation
or soreness of throat and nose. |
Eye Contact |
Dust may cause temporary
irritation or inflammation. |
Skin Contact |
May cause temporary
dryness, irritation or rash. |
Ingestion |
Ingestion is unlikely. May cause gastrointestinal
disturbances. Never induce vomiting
without the advice of a physician. |
Medical Conditions Aggravated by Exposure: Respiratory effects may be aggravated by
smoking. Pre-existing respiratory
problems may be aggravated by dust. |
4. First Aid
Measures
Inhalation: Remove to fresh air. Rinse mouth to clear throat and expel
liquid. Blow nose to evacuate dust. Consult a physician if irritation persists.
Eye Contact: Do not rub eyes. Keep hands or contaminated body parts away
from eyes. Remove contact lenses. Flush with water. If irritation persists, consult a physician.
Skin Contact: Wash with soap and water. For dryness, a skin cream may be
helpful. Do not apply anything to a
rash. Consult a physician if irritation
persists.
Ingestion: Do not induce vomiting without advice of a
physician. Seek medical attention.
Note to Physicians: Aluminum Oxide dusts have caused no known
systemic or pathological problems. The
material is inert in the body. Some
individuals may experience allergic sensitivity reactions. These are generally limited to mild
occupational dermatitis. Chronic
inhalation may result in pleural plaques not associated with cancers. Other effects principally derived from
physical abrasion.
These products contain a small
percentage of amorphous silica, however, not in sufficient quantity to produce
free crystalline silica upon heating.
Dusts are therefore considered of the inert (nuisance) type and would
not be expected to cause permanent damage to tissues on inhalation unless the
exposure is severe. Chronic exposure may
produce radioplaque deposits in the pulmonary system with little or no
parenchymal reactions. Some individuals may exhibit allergenic
reactions ranging from asthmatic symptoms to benign pneumoconiosis.
Product as shipped can cause irritation
to exposed tissue. Prolonged contact can
cause local irritation or burns to exposed tissue. Phosphoric acid is slightly toxic with
repeated inhalation or ingestion.
As shipped, this product is a corrosive
liquid (contains phosphoric acid). The
major hazard is from direct physical contact or ingestion, unless a mist is
somehow evolved into the air. If exposed
areas are flushed promptly and thoroughly with water, there should be not ill
effects. Appropriate personal protective
equipment should be worn when applying this product.
5. Fire
Fighting Measures
Materials are not
combustible.
Unusual Fire or Explosion
hazards: Thermal decompositon of
phosphoric acid may emit irritating phosphoric oxide fumes.
Special Fire-Fighting Prodedures: Wear full protective equipment and self-contained breathing apparatus.
6. Accidental
Release Measures
Spill Procedures: Clean
up procedures should minimize formation of airborne dusts. Remove dust by vacuuming using HEPA
filtration where possible. Liquid products (groups 3 & 4) should be cleaned up with sponge, mop or
cloth. Contain and neutralize liquid,
then flush with water.
Release into Air: Prevent
release of airborne particulates where possible. Not a regulated hazardous substance. See section 8 for appropriate engineering
controls.
Release into Water: Release into water is not appropriate. Not a regulated hazardous substance. Landfill dusts and debris consistent with local regulations.
7. Handling
and Storage
Storage:
These materials are stable and
may be stored indefinitely. Physical
abrasion may produce small amounts of respirable dusts. Liquid and moist
products (groups 4, 5, 7 and 8) should be stored in a sealed container. See
precautions under section 8.
Normal Use: Materials
are stable under normal use and are not expected to produce significant
hazardous by-products or emissions.
Machining and Cutting: These
materials may produce respirable and nuisance dusts when machined or cut. See section 8 for exposure controls and
personal protection during machining or installation procedures.
High Temperature Conditions: Service
significantly above the product design temperature may increase friability and
the possibility of generating airborne fibers or particulates. While not considered problematic during use,
airborne fibers may complicate removal activities. It is recommended that product use be
carefully matched to design parameters.
After Service: Product removal must consider the possibility of usage above design
temperatures. See section 8 for appropriate
respiratory protection during removal.
8. Exposure
Controls
Engineering Controls: |
Respiratory Protection: |
Use appropriate protection
pursuant to OSHA 29CFR 1910.134 and 29CFR 1926.103. The following information is provided as a
guide and reflects industry recommendations for control of dust. |
PPE Other
|
Work clothes should be
washed separately and the washing machine rinsed following use. If possible, do not take work clothes home
following machining or removal activities that produce significant amounts of
dust. |
Skin Protection
|
Wear gloves, head
coverings, and full body clothing to prevent skin irritation. Disposable clothing may be used. Store work clothes and street clothes
separately. |
Eye Protection
|
Wear safety glasses or
chemical goggles to prevent eye contact.
Do not wear contact lenses without goggles. Do not get dust or liquids into eyes. Have eye washing facilities available when
using products. |
These products are
generally not hazardous during normal use.
These guidelines are provided for special circumstances involved in
machining , use and or after service removals. See section 7 for after
service and section 13 for disposal recommendations. |

10. Stability
and Reactivity
Stability: Materials are
stable.
Chemical Incompatibilities: Powerful oxidizers; fluorine, chlorine
trifluoride, manganese trioxide, oxygen difluoride, etc. Avoid contact with active metals such as mild
steel and aluminum.

12. Ecological
Information
Ecotoxicological Information: No
information available.
Distribution: Aluminum
oxide and silica are naturally occurring and are widely distributed in igneous
rock. Secondary deposits in sedimentary
rock may be found.
Chemical Fate Information: The relative inertness of this material indicate that it may be highly persistent in the environment. No information regarding any negative effects of this persistence has been noted.
