Inspector scope · Reference onlyWho this is for and what it does not replace

Walk through a shipping paper UN by UN: each line becomes a tile; hazard-class icons (placard reference) and §177.848 segregation update as an audit snapshot for the whole vehicle load. Based on 49 CFR §172.101.

  • Inspectors: CVI-style checks of papers, labels, placard types vs §172.504, and mixed-class loads at roadside or facility
  • Auditors: Carrier self-audit, training, or pre-trip review against the same 49 CFR references
  • Shows: 49 CFR §177.848, transparent §172.504 placard trace (49 CFR §172.504), ERG and HMT detail per line
  • Not: Computed placard mandates, official inspection file, violation notice, or quantity/weight certification unless you enter quantities
