All forms of chromium identified to us by sup pliers end listed in the "catalog" have been previously listed in a "witch hunt". /K toe Industrial Relations Bulletin entitled "toxicology", Bulletin #26 (copy at** tacbed), addresses the potential hazards associated with metals. Information in this Bulletin acknowledges that certain metal products present insignificant risk in their anticipated use, handling and disposal (irrespective of any chromium con tent). Such materials would not he addressed in the "catalog" since 1291 Forms would not normally he required as indicated in Bulletin #26.

Materlale fteouirinr Preoautlone But Not Forme 1593 and 68-100 Materials In classes: MIA Ferrous M2A Non-Ferrous M3A Tool, Die & Equipment Steels M5A Wire, Spring Steel M6A Electrical M7A Anodes MBA Bearing Metals M9A Shot & Grit .' can be ejected to present little or no hazard, except ae described below, in their intended use, handling and storage. No Material Health and Safety Data Sheet - Form 1291, or Environmental Data Sheet - Form 68-100, need be submitted for these materials at thiB time. Possible Hazards: Processing these materials may present hazards where grinding, melting, cutting, welding or other operations produce fusee, dust, emoke or other products of attrition which may enter the breathing zone of employee. Fumes or duBt from those operations generating Buch, can be expected to contain not only the base metal and lta oxide (e.g. iron oxide, zinc oxide, lead, aluminum oxide, nickel, nickel oxide, etc.) but also measurable amounts of other metals and non-metals used as alloys or coatings (e.g., vanadium, chromium, arsenic, beryllium, lead, antimony, etc.). Such materlale if inhaled in sufficient concentration may lead to adverse pulmonary and/or systemic health effects. Precautionary Measures: For those processes where fume, fine particulate, etc., may be generated and inhaled by employes, ventilation must be adequate to maintain the concentration of all airborne contaminants within acceptable limits. Additionally, certain metale (e.g., antimony, chromium) may present skin hazards (dermatitis) especially in the finely divided state. Protective gloves and other garments may be nec essary in the handling of metal fines. A determination of adequacy of workplace ventilation during processing of these materials can be performed by the Industrial Hygiene Services Section of the Industrial Hygiene and Toxicology Department. Plant Engineering Offioe - Man ufacturing Staff can assist in determining feasibility and design criteria for ventilation. 6001 1B17 *' OT> rvrsx Disposal: Metals la these claeeee should he recycled as metallic scrap whenever possible. Unrecyclable scrap can be disposed of in a approved sanitary landfill. Disposal of metal fines into plant Bever systems is not an acceptable practice. Plant Engineering Office - Manufacturing Staff (PEO) can be contacted for information on Bolid and liquid waste management. Stationary Source Environmental Control Office (SSECO) - Environmental and Safety Engineering Staff should be contacted regarding any question on applicable environmental regulations.j II. Materials Requiring Fonns.1291. and 68-100 Materials in classes: MkA Metals Welding, Brazing and Fillers M10A Powders, Metal M11A Solders M12A Lubricant, Solid Film require that Forms 1291 and 68-100 be submitted. The primary concern with these four classes of "Metals" is that because of their nature and/or intended use there is a significant probability that, without proper precautions, they will enter the work environment as dust or fume in excess of acceptable limits'. Ingredients such as, but not limited to, chromium, cadmium, vanadium, beryllium,'arsenic, lead, nickel, and zinc can present unreasonable risk to employes and/or the environment without proper controls. The controls to prevent excessive inhalation and skin contact with these materials as well as any periodic monitoring, record keeping, medical examinations, etc. which may be required by law will be indicated in the material review where applicable, as new products are proposed for these classes. Due to the composition and nature of these materials, restrictions may be placed on their disposal. It must be recognized that the concentration of certain constituents may classify the "Metal" as a hazardous waste. Disposal of metal fines in plant sewer systems is not an acceptable practice. Contact PEO for information on Bolid and liquid waste management. SSECO should be consulted regarding questions on applicable environmental regulations. Note: The information above does not apply to combustion (thermal decomposition) products resulting from subjecting these products to overheating or fire situations. Products of combustion from these materials will vary in quality and quantity depending on temperature rise, oxygen available, amount combusted, and volume in which material is combusted. Specific concerns related to hazards of combustion products, should they arise, should be addressed to Industrial Byglene and Toxicology.* * Manufacturing Staff, Office of General Counsel, Environmental and Safety Engineering Staff, and Engineering & Research Staff concur with this bulletin.
