1.1 This standard offers a guide for safe disposal of wastes of unbound silicon carbide whiskers and fibers and wastes containing 1.0% by weight or greater of unbound silicon carbide whiskers and fibers, which could become airborne during disposal operations or uncontrolled releases of materials during disposal operations. Silicon carbide whiskers are not naturally occurring, and such waste could only be generated during the manufacture of silicon carbide whiskers or their composites.

1.2 If the waste stream contains or is mixed with other constituents that are considered hazardous waste by area federal, state, or local regulations, the disposal requirements are more stringent or require different handling precautions, or both, than those described in this guide. Information specific to these hazardous constituents should be included in each generator's characterization of the waste so that it can be properly managed as a hazardous waste.

1.3 Application of this document must be in accordance with federal, state, county, and local solid waste regulations, or other authorities having such jurisdiction.

1.4 Applicable information may be obtained from the Material Safety Data Sheet(s) (MSDS) for the waste stream constituent(s).

1.5 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
