CANCER:
  WARNING: Contains a chemical which can cause cancer. (CERAMIC FIBERS)
  (IARC possible human carcinogen 2B, Calif. Proposition 65)
                                                                             
  Due to their large size, Nextel(TM) Ceramic Fibers are considered to
  be non-respirable and, therefore, unlikely to pose a cancer risk.
  Respirable fibers are defined by the World Health Organization as
  having lengths greater than 5 microns, diameters less than 3 microns
  and length-to-diameter ratios greater than 3:1. Nextel(TM) Ceramic
  Fibers have diameters of 7 to 13 microns and are continuous in
  length.
