49 CFR Lookup Reference

A complete rebuild. 49 CFR and the ERG are now one fully offline app with one search. EVERYTHING SEARCHABLE • All 1,010 pages of 49 CFR Parts 100–177 (Oct 1, 2024 edition) are now searchable word for word, including the Hazardous Materials Table, appendices, front matter and finding aids. • Tables keep their row layout, so the radionuclide, portable tank, organic peroxide and segregation tables read the way they're printed. • Text inside figures and image-only pages is now searchable too, including the §173.62 explosives packing tables, labels, placards and markings. • Hyphenated words that break across lines in the source are still found when you search for the whole word. ONE SEARCH FOR EVERYTHING • A single search box covers the Hazardous Materials Table, every regulation section, ERG 2024 and every PDF page at once. • Results are grouped into Materials, 49 CFR text, ERG and PDF pages, with matches highlighted. • Shortcuts: type a UN/NA number (1203, UN1203, NA1993), a section (173.62), a part (part 177) or a guide (guide 128) to jump straight there. 49 CFR AND ERG TIED TOGETHER Every material now has one page showing: • Its ERG guide, with key hazards and evacuation distances • Table 1 isolation and protective action distances for TIH materials, and Table 2 water-reactive warnings • All 10 Hazardous Materials Table columns • Special provisions explained in plain text, one tap to expand • Packaging sections as direct links • Placard table (Table 1 or Table 2) under §172.504 • Reportable quantity and marine pollutant status • Other entries that share the same ID number Explosives now link to ERG Guide 112 or 114 by division. PLACARDS FOR EVERY MATERIAL • New, sharp DOT-style placards for every hazard class and division, including all six explosives divisions, FLAMMABLE GAS, OXYGEN, INHALATION HAZARD, NON-FLAMMABLE GAS, FUEL OIL, COMBUSTIBLE, GASOLINE, DANGEROUS WHEN WET, FLAMMABLE SOLID, SPONTANEOUSLY COMBUSTIBLE, DANGEROUS, OXIDIZER, ORGANIC PEROXIDE, POISON, TOXIC, RADIOACTIVE, CORROSIVE and CLASS 9. • Explosives show their exact division and compatibility group (e.g. 1.4G, 1.1D). • Each material shows its primary placard, permitted alternates, subsidiary labels and the DANGEROUS option where it applies. • Placard icons appear in search results and the materials list. • Rebuilt placard-to-guide chart, plus infectious substance, lithium battery and orange ID-panel references. EASIER TO READ AND USE • New layout: sidebar on iPad and desktop, bottom tab bar on iPhone. • Regulation text now reads as normal paragraphs instead of narrow PDF column breaks. • Section references (§173.304) and UN numbers in the regulation text are tappable links. • PDF page viewer with page jump, previous/next and links to the sections on each page. • Adjustable text size, light and dark themes, and a recent items list. • Back navigation works throughout the app. • Materials list filters for class, TIH, reportable quantity, marine pollutant and forbidden. • Browse all special provisions and see which materials use each one. • One-tap calling for CHEMTREC and the National Response Center. FIXES • Corrected starting pages for 29 regulation sections. • Separated Appendices A and B to §172.101 and the Part 107 penalty guidelines into their own entries. • Repaired truncated section and appendix titles.
