Special Instructions for SARA 313 Chemicals:
The chemicals present in this product which are marked with an asterisk (*) are subject to the reporting requirements of Section 313 of Title III of the Superfund Amendment and Reauthorization Act of 1986 in 40 CFR, Part 372. If no percentage is shown, the chemical represents less than 1% by weight of the product (the chemical is not a carcinogen) or less than 0.1% (if the chemical is a known or suspected carcinogen).
** Aluminum and Zinc are only reportable as dust or fume.

Special Fire Fighting Procedures: Solid, massive form is not combustible. 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 (SCBA)and protective clothing.

Aluminum dust/fines and fumes are a low health risk by inhalation and are normally treated as nuisance dust in normal operations (e.g., milling, cutting, and grinding).

In some workers, chromium compounds act as allergens and may cause dermatitis and may also produce pulmonary sensitization. Chromic acid and Chromate’s have a direct corrosive effect on the skin and the mucous membrane of the upper respiratory tract. Although rare, there may be the possibility of skin and pulmonary sensitization. IARC has determined that there is sufficient evidence of increased lung cancer among workers in the chromate-producing industry and possibly chromium alloy workers. This determination is supported by sufficient evidence for carcinogenicity to animals and possible muta-genicity testing of Cr-VI compounds.

Melting, grinding, cutting of copper may produce fumes or dust exposure and breathing these fumes or dust may present potentially significant health hazards. Fumes or copper may cause metal fume fever with flu-like symptoms and skin discoloration. While industrial dermatitis has not been reported, keratinization of the hands and the soles of the feet have been reported. Systemically as well, copper dust and fume cause irritation of the upper respiratory tract, metallic taste in the mouth, and nausea. Chronic poisoning results in Wilson’s disease, characterized by a hepatic cirrhosis, brain damage, demyelination, renal disease and copper deposition in the cornea.

The inhalation of iron oxide fumes may cause an apparent benign pneumoconiosis that 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 (generally over two years exposer). The pathology resembles Parkinson’s Disease. Chronic manganese poisoning is not a fatal disease although it is extremely disabling. Some individuals may be hypersusceptible to manganese. Freshly formed manganese fume has caused fever and chills similar to metal fume fever.

Inhalation of the dust or fumes of this metal can cause upper respiratory system irritation. While no cases of industrial poisoning have been reported, laboratory experiments with animals have shown cumulative liver and kidney damage (fatty changes) and blood disorders.

Nickel

The most common ailment arising from contact with nickel or its compounds is an allergic dermatitis 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 under water and is transferred as a liquid. Yellow phosphorus is toxic and may produce poisoning if taken by mouth. Contact with skin may cause severe and painful burns and the contact area turns grayish-white. Often, there is infection. Respiratory tract irritation has been caused by inhalation of vapors (oxides). Chronic poisoning takes form of general weakness, including anemia, loss of appetite, indigestion, chronic cough resulting from irritation of the gastrointestinal system and fatty degeneration of the liver.

Inhalation Hazard—The disease associated with chronic (long-term) exposure to free crystalline silica is silicosis. This is a form of pneumoconiosis, which is characterized by the formation of nodules of scar tissue (fibrosis) throughout the lings. Silicosis can cause difficult or labored breathing, especially on exertion, decreased physical work capacity, and sometimes an enlarged chest. The degree of hazard depends upon the silica content, concentration and size of the airborne dust, as well as the length of exposure. Silicosis may also make the lungs more susceptible to other diseases and silicotuberculosis can be a severe complication.

NOTE: If grinding or any work is done on the casting, release of silica may result

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, local regulations.

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.

Respiratory Protection: If exposure above the PEL, TLV, NIOSH approved respirator for fume or dust, dependent upon the source of airborne contaminant.

Ventilation: Required if dust or fume is created in handling or working on this material.

Local Exhaust:required if dust or fume is created in handling or working on this material.

Eye Protection: Required for melt, grind, cut, and weld operations. Minimum requirement of safety glasses with side shields for these operations. Melting and welding may require special eye protection including face shields and special tinted glass. Grinding operations may also require face shield.

Other Protective Clothing or Equipment: As required for work done on or with the steel castings.

Work/Hygiene Practices: As required for the rework or additional work done on this product in accordance with OSHA or relevant state or local standards. Always evaluate the jobs being done on this product per the information contained on this data sheet.

These castings were produced in a silica sand mold. Therefore, there may be some residual sand on the surface of the castings or lying loose on or inside the product. Precautions must be taken if handling or work on the castings would release or cause this silica to become airborne in the breathing zone of workers. Refer to the sections on Health Hazards and Control measures.

Those chemicals marked with an asterisk (*) are subject to the reporting requirements of section 313 of Title III of the Superfund Amendment and Reauthorization Act of 1986 in 40 CFR, Part 372.
