SECTION 4 - FIRE AND EXPLOSION HAZARD OF MATERIAL
|
FLAMMABILITY: YES? NO? X
FLASH POINT (Method Used): N/A |
|
WHAT CONDITIONS? N/A
UEL: N/A
LEL: N/A |
MEANS OF EXTINCTION:
This product is non-combustible in bulk form. For fires involving aluminum fines or chips, use dry sand or Class D extinguishing agents approved for this use. DO NOT USE water or other liquids, foam, or halogenated extinguishing agents.
SPECIAL PROCEDURES:
Suspended aluminum dust, allowed to accumulate in a confined area, may be explosive. If remelted, moisture present in cavities or on external surfaces may cause an explosion |

SECTION 5 - REACTIVITY DATA
|
| CHEMICAL STABILITY: Stable
REACTIVITY AND UNDER WHAT CONDITIONS:
If remelted, moisture present in cavities or on external surfaces may cause an explosion. Bulk aluminum dust when damp may heat spontaneously.
INCOMPATIBILITY TO OTHER SUBSTANCES: YES
For aluminum fines: water, some acids, alkalis, and halogenated compounds. See NFPA#491M for specific incompatible materials. National Fire Protection Association, Batterymarch Park, Ouincy, MA 02269.
HAZARDOUS DECOMPOSITION PRODUCTS: YES
Finely divided aluminum reacts with water, some acids, and alkalis to produce hydrogen gas. Aluminum in contact with halogenated compounds can produce violent reactions and/or explosions.

SECTION 6 - TOXICOLOGICAL PROPERTIES OF PRODUCT
|
| ROUTE(S) OF ENTRY: |
|
|
INHALATION? YES
EYE CONTACT? YES |
|
INGESTION? NO
SKIN ABSORPTION? NO |
EFFECTS OF ACUTE EXPOSURE:
Aluminum is considered a nuisance particulate. Welding or machining aluminum may generate dusts and fumes which may cause eye, nose, and throat irritation. Generally, if exposures for aluminum oxide are kept below the exposure limit, the alloy components should not present a health risk. Ozone may be emitted as a by-product during welding or plasma arc cutting. Exposure to ozone may produce irritation to eyes, nose, and throat. Welding and/or plasma arc cutting of aluminum alloys generates ultraviolet radiation which can cause skin burns or welders flash to unprotected skin and eyes.
EFFECTS OF CHRONIC EXPOSURE:
Prolonged exposure to ozone may result in nausea, headache, and pulmonary damage. Chromium and certain of its compounds are classified as carcinogens in the latest Annual Report on Carcinogens as published by the National Toxicology Program (NTP) and by the International Agency for Research on Cancer (IARC). |

SECTION 7 - PREVENTIVE MEASURES
|
| PERSONAL PROTECTIVE EQUIPMENT:
GLOVES: As needed.
EYEWEAR: Safety glasses, goggles, face shield, or welding helmet, etc., as needed.
RESPIRATORY: Use NlOSH/MSHA-approved respirator for dusts/fume/mist, if TLVs or PELs are exceeded.
FOOTWEAR: Safety shoes, as needed.
CLOTHING:
Appropriate welding protective equipment. If remelted, see Aluminum Association publication "Guidelines for Handling Molten Aluminum", #69. The Aluminum Association, 900 19th St., N.W., Suite 300, Washington, D.C. 20006.
ENGINEERING CONTROLS:
If ventilation is used to convey aluminum dust, generated by grinding, sawing, etc., special ventilation procedures may be necessary to avoid explosion hazards. See National Fire Protection Association codes #65 and #651
LEAK AND SPILL PROCEDURE: If remelted, see Aluminum Association publication #69 listed above.
WASTE DISPOSAL:
For disposal of this material as a waste, act in accordance with all applicable federal, state, and local waste management regulations.
