  2. Occupational exposure banding - Wikipedia

    en.wikipedia.org/wiki/Occupational_exposure_banding

    Tier 2 banding is also incorporated into the NIOSH OEB e-tool but can take hours instead of minutes to complete for a given chemical. However, the resulting band is considered more robust than a Tier 1 band due to the in-depth retrieval of published data. [7] NIOSH recommends users complete at least the Tier 2 process to produce reliable OEBs.

    An occupational exposure limit is an upper limit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. It is typically set by competent national authorities and enforced by legislation to protect occupational safety and health.

    en.wikipedia.org/wiki/List_of_UWB_channels

    The Time Frequency Codes (TFC) define the frequency interleaving sequence for utilizing 1-3 of the bands within a band group. TFCs 1-4 are for TFI channels, TFCs 5-7 are for FFI channels, and TFCs 8-10 are for TFI2 channels, which simply interleave their data across two bands. Note that all TFCs will be in the same band at some time during ...
