III. PHYSICAL DATA
Fire Fighting Procedures: Solid,
massive form is not combustible under normal conditions. Use fire fighting methods that are appropriate
for surrounding fire. Fire and explosion hazards are moderate when
material is in the form of dust and exposed to heat, flames, chemical reaction, or contact with powerful oxidizers. Use
special mixtures of dry chemical or sand. Firefighters should wear self-contained breathing
apparatus and protective clothing.
Permissible Exposure Limits and Threshold Limit Values: See Section II
Route(s) of Entry: Inhalation: Yes Ingestion: Yes Skin: Yes
Aluminum dust/fines and fumes are a low health risk by inhalation and are normally treated as a nuisance dust in normal operations (e.g., milling, cutting, grinding). The AIHA Hygiene guide lists toxicity of ingestion as “none expected”.
Antimony and its compounds are irritating to the skin and mucous membranes and are systemic poisons. Effects are reported to include a metallic taste in the mouth, vomiting, colic, loss of appetite and weight, and diarrhea. In addition, dermatitis may result which starts as an inflammation of the hair follicles and can progress through pus formation and sloughing to leave a contracted scar. Chronic inhalation of antimony trioxide is reported to produce a reduction in white blood cells and damage to the liver. Antimony and its compounds have been identified as suspected cancer-causing agents.
Meting, grinding, cutting of copper may produce fumes or dust exposure and breathing these fumes or dust may present potentially significant health hazards. Fumes of copper may cause metal fume fever with flu-like symptoms and skin and hair discoloration. While industrial dermatitis has not been reported, keratinization of the hands and the soles of the feet has been reported. Systematically as well, copper dust and fume cause irritation of the upper respiratory tract, metallic taste in the mouth, and nausea.
The inhalation of iron oxide fumes may cause an apparent benign pneumoconiosis which is called siderosis. This disease is reported not to be disabling, but makes x-ray of other lung conditions difficult or impossible.
Chronic manganese poisoning may result from inhalation of dust or fume. The central nervous system is the chief site of the injury. Chronic manganese poisoning is not a fatal disease although it is extremely disabling. Some individuals may be hypersusceptible to manganese. Freshly formed manganese fume base has caused fever and chills similar to metal fume fever.
common ailment arising from contact with nickel or its compounds is an allergic dermatitits known as “nickel itch”
which usually occurs when the skin is moist.
Generally nickel and
most salts of nickel do not cause systemic poisoning. IARC has determined
that there is at least limited evidence that nickel and certain nickel compounds may be human carcinogens. Several nickel compounds are carcinogenic
to laboratory animals by various routes of entry.
Red phosphorus does not react with the air and is extremely insoluble making it harmless. Yellow phosphorus is extremely flammable. The liquid ignites spontaneously in the presence of air. It is normally stored as a solid kept underwater and is transferred as a liquid. Yellow phosphorus is toxic and may produce poisoning if taken by mouth. Chronic poisoning takes the form of general weakness, including anemia, loss of appetite, indigestion, and chronic cough resulting from irritation of the gastrointestinal system and fatty degeneration of the liver.
Silicon is a nuisance dust. Deposition in the eyes, ears, skin, and nose may result in injury. Inhalation produces no change in x-ray.
The inhalation of inorganic tin fumes or dust may cause an apparent benign pneumoconiosis called stenosis which is not reported to be disabling.
*Zinc (as an oxide):
relatively low in toxicity but inhalation of fumes may cause “metal fume fever”. Onset of symptoms may
be delayed 4 - 12 hours and include irritation of the nose, mouth, and throat, cough, stomach pain, headache, nausea,
vomiting, metallic taste, chills, fever, pains in the muscles and joints, thirst, bronchitis or pneumonia and a
bluish tint to the skin. These symptoms go away
in 24 - 48 hours and leave no effect.
Emergency and First Aid Procedures:
Eye Contact: Flush well with running water to particulate. Get medical attention.
Skin Contact: Vacuum off excess dust. Wash well with soap and water. Avoid blowing particulate into the atmosphere.
Inhalation: Remove to fresh air. Get medical attention.
Ingestion: Seek medical attention if large quantities
of material have been ingested. Check airborne levels
of lead and employee blood levels in accordance with OSHA standards.
VI. REACTIVITY DATA
Stability: Stable under normal conditions of use, storage, and transportation.
Conditions to Avoid: Molten metal may react violently with water.
Incompatibility (Materials to Avoid): Acids, bases, and oxidizers.
Hazardous Decomposition or Byproducts: Metal fume. NOTE: If grinding or any work is done on the casting, release of silica may result from residual sand on the surface of the casting.
Steps to be Taken in Case Material is Released or Spilled: No special precautions are necessary for spills of bulk material. If large quantities of dust are spilled, remove by vacuuming or wet sweeping to prevent heavy concentrations of airborne dust. Follow federal, state, and local regulations concerning the disposal of waste.
Waste Disposal Method: Dispose of in accordance with federal, state, and local regulations. Cleanup personnel should wear respirators and protective clothing.
Precautions to be Taken in Handling and Storing: Store material away from incompatible materials and keep dust from sources of ignition.
Other Precautions: See all other sections of this
VIII. CONTROL MEASURES
Respiratory Protection: If exposure above the PEL or TLV, NIOSH approved respirator for fume or dust, dependent upon the source of airborne contaminant.
Ventilation: Required if dust or fume created in handling or working on this material.
Local Exhaust: Required if dust or fume created in handling or working on this material.
Mechanical (General): As above to reduce airborne dust or fume levels.
Protective Gloves: Required for melt, grind, weld operations. Select glove approved for the specific operation.
Eye Protection: Required for melt, gring, cut or weld operations. Minimum requirement of safety glasses with side shield for these operations. Melting and welding may require special eye protection including face shields and specially tinted glass. Grinding operations may also require faceshield.
Other Protective Clothing or Equipment: As required for the work done.
Work/Hygiene Practices: No food may be allowed in the work area. Always wash thoroughly before leaving work area. Work clothes must be stored separate from street clothing and be marked for laundering. Always evaluate the jobs done on this product in accordance with OSHA or revenant state, federal, or local standards.
