Section 2
SECTION 2: Hazards identification
OSHA Classification of the substance or mixture This product is not classified as a hazardous substance or mixture. This product does not need to be labelled as hazardous
2.2 Label elements
This substance does not need to be labelled in accordance with EC directives or respective national laws.
2.3 Other hazards
Silicon carbide (SiC) microfibers/ whiskers are a fibrous form of single-crystal silicon carbide having an aspect ratio of 3:1 or greater. SiC microfibers/ whiskers are non-toxic by ingestion, have no extractables, and are even approved for food contact in some situations. Raw, dry SiC microfibers/ whiskers may become airborne during handling and become respirable in some conditions. When dispersed in water, solvent, polymer, or other carrier material (when wetted), SiC microfibers/whiskers are non-respirable and non-hazardous. When SiC microfibers/whiskers are incorporated into a matrix material or composite system (for example a polymer coating), they are non-respirable and non- hazardous. Under such conditions, there is no evidence to suggest that SiC microfiber or whisker ever become respirable, even when these matrix material or composite systems are subjected to mechanical wear.
2.1 Classification of the substance or mixture
