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 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.
5. Fire
Fighting Measures
Materials are not
combustible.
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 and moist products (groups 3, 4, and 5) should be cleaned up with sponge, mop or
cloth.
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 3, 4, and 5) 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: AS MANUFACTURED THIS PRODUCT
IS AN ALUMINOSILICATE WHICH MAY TRANSFORM UPON HEATING (TEMPERATURES GREATER
THAN 1000oC FOR EXTENDED PERIODS OF TIME) TO NON‑HAZARDOUS
MULLITE AND CRISTOBALITE (CAS # 14464‑46‑1), A FORM OF CRYSTALLINE
SILICA. REMOVAL OF THIS PRODUCT AFTER
USE MAY GENERATE DUSTS. PROLONGED OR
REPEATED INHALATION OF RESPIRABLE FREE CRYSTALLINE SILICA DUST MAY CAUSE
DELAYED LUNG INJURY (SILICOSIS). THE
IARC HAS CLASSIFIED CRYSTALLINE SILICA AS GROUP 2A, PROBABLE HUMAN
CARCINOGEN. THERE IS SUFFICIENT EVIDENCE
OF CARCINOGENICITY IN ANIMALS, BUT LIMITED EVIDENCE IN HUMANS. OSHA'S FINAL RULE LIMIT AND ACGIH'S TLV FOR
RESPIRABLE CRISTOBALITE IS 0.05 mg/m3. APPROPRIATE VENTILATION AND RESPIRATORY
PROTECTION SHOULD BE PROVIDED IN COMPLIANCE WITH OSHA STANDARDS. STRICT ADHERENCE TO RECOMMENDED SAFE WORK
PRACTICES IS ADVISED. PRODUCT REMOVAL MUST CONSIDER THE POSSIBILITY OF USAGE
ABOVE DESIGN TEMPERATURES.
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: |
Use dust suppression
controls. Local exhaust ventilation,
point of generation dust collection, and/or down-draft work stations to
minimize airborne dust generation are recommended when machining product. |
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. |
