FIRED CORE PRODUCTS

SECTION 2: Hazards identification

Product definition

These products are resin-coated, pale yellow-colored solids in formed, block form. The PA-21 Alumina Coated Fired Core product is purple in color. The D-100 Cobalt Fired Core product is blue in color. Health Hazards: These products are considered a manufactured article and present negligible health, or reactivity hazards under typical use conditions. Mishandling of the product may result in abrasion. If end-use produces dust, inhalation of dusts may irritate the nose, throat, and respiratory system. Dusts or particulates may irritate the eyes (as foreign particles). If heated, burns may occur from hot product. Repeated inhalation of dust or particulates from these products may cause silicosis and reduced lung function. The Phenolic Resin component of this product contains formaldehyde. Formaldehyde is a known human carcinogen, known skin sensitizer and respiratory sensitizer and reproductive toxin. Normal handling should not result in exposure to formaldehyde. In event these products are heated, causing decomposition of the resin and evolution of formaldehyde fumes, exposure to formaldehyde may be possible. Flammability Hazards: These products are not flammable. The products are designed to withstand high temperatures and should not produce any toxic decomposition products unless heated above 1538°C (2800°F) for prolonged periods. Above this temperature they may produce carbon, magnesium, silicon, alumina, cobalt and zirconium oxides and silicates, formaldehyde, formic acid, acetone, methanol, aldehydes, ketones and acids, 2,4- dimethyl-1-heptene, 2-pentene, propylene, 2-methyl-1-pentene, and isobutylene. Reactivity Hazards: These products are not reactive. Environmental Hazards: These products do not present any hazard to the environment. Emergency Response Procedures: Emergency responders must wear the proper personal protective equipment suitable for the situation to which they are responding.
