NICKEL ALUMINIDE COATINGS

SECTION 2: Hazards identification

Emergency overview Solid. Gray. Odorless. Non-combustible as supplied. Dust and fines from processing may be ignitable. Explosion/fire hazards may be present when (See Sections 5, 7 and 10 for additional information): • Heavily concentrated dust clouds are dispersed in the air.

Potential health effects

from mechanical processing (e.g., cutting, grinding) Dust Can cause irritation of the eyes, skin and upper respiratory tract. These coatings are deposited by various processes onto the surface of Superalloy castings. Occupational exposures would be limited to skin contact unless processing occurs which generates dusts (e.g., cutting or grinding). Under those conditions, exposures could also include components of the Superalloys. The following statements summarize the health effects generally expected in cases of overexposures. User specific situations should be assessed by a qualified individual. Additional health information can be found in Section 11. The health effects listed below are not likely to occur unless processing of this product generates dusts. Eyes Dust from processing: Can cause irritation and inflammation of the eyes and eyelids. Skin Dust from processing: Can cause irritation. Prolonged or repeated skin contact may cause sensitization and allergic contact dermatitis. Inhalation from mechanical processing (e.g., cutting, grinding) Dust Can cause irritation of the upper respiratory tract. Chronic overexposures: Can cause respiratory sensitization, scarring of the lungs (pulmonary fibrosis) and damage to the heart muscle (cardiomyopathy). Carcinogenicity and Product as shipped: Does not present any cancer or reproductive hazards. Reproductive Hazard Dust from mechanical processing: Can present a cancer hazard (Cobalt, Nickel). Does not present any reproductive hazards. Medical conditions Dust from processing: Asthma, chronic lung disease, and skin rashes. aggravated by exposure to product
