Hazardous Materials Transportation Checklist

Use the shipper's SDS and the Hazardous Materials Table to confirm proper shipping name, UN/NA identification number, hazard class/division, packing group, and any subsidiary hazards. Mismatches between the SDS and the BOL are the most common reason hazmat loads get rejected at the dock or red-tagged at roadside.

Class 1 explosives, Class 7 radioactives, and inhalation-hazard materials trigger HM-232 routing rules. Check state-by-state restrictions (NYC tunnel network, Boston Tobin/Sumner, Baltimore Harbor, Washington DC) and confirm the routing plan is filed if the load is a placarded explosives or HRCQ shipment.

Inspect the UN packaging mark (e.g., 1A1/Y1.4/150) and confirm it matches the packing group and product. Drums beyond their 5-year reconditioning date, IBCs past their 2.5-year inspection, or cylinders with expired hydro dates fail at the dock.

Per 49 CFR 172.202, the basic description must be in the order: UN ID, proper shipping name, hazard class, packing group (e.g., UN1203, Gasoline, 3, II). Include total quantity, number and type of packages, and the shipper's certification signature. The 24/7 emergency response phone number with monitoring (CHEMTREC 1-800-424-9300 or registered alternate) must appear on the BOL — a missing ERP phone is an automatic OOS.

Proper shipping name and UN number marked on the package, primary hazard label affixed adjacent to the marking, subsidiary labels where applicable, orientation arrows on liquids, and the shipper's name and address on the outer package. Cross-check against the BOL line-by-line before sealing the trailer.

Standard Part 396 pre-trip plus hazmat-specific items: fire extinguisher (10 B:C minimum for placarded loads, charged and within inspection date), no exposed wiring near the cargo area, no leaks or residue from a prior load, trailer interior clean for the commodity class.

Cross-check every commodity pair against the 49 CFR 177.848 segregation table. Common traps: oxidizers (5.1) with flammable liquids (3), corrosives with cyanides, and Division 6.1 PIH materials with anything in the food chain. Document the loading diagram for the file.

Tie-downs rated to the working load limit, cylinders upright and chocked or chained, drums on pallets shrink-wrapped and braced against forward shift. The cargo must withstand 0.8g deceleration forward, 0.5g rearward and lateral.

CDL with H or X endorsement, current and not expired. TWIC required if the route enters a regulated port facility. A driver hauling placarded hazmat without a current H endorsement is an OOS violation and a CSA hit under Driver Fitness.

Per 49 CFR 172.704, every hazmat employee needs general awareness, function-specific, safety, security awareness, and (if applicable) in-depth security training every three years. Pull the training record from the DQ file and confirm the cycle date.

Match PPE to the SDS section 8: nitrile or Viton gloves, splash goggles, face shield for corrosives, Tyvek or chemical-resistant suit for spill response, and an escape respirator for PIH commodities. Stash in the side box, not buried in the sleeper.

If the shipper uses CHEMTREC as the 24/7 ERP provider, the CCN must appear on the shipping paper. Verify the number with the dispatcher; an invalid or unregistered ERP phone fails roadside and exposes the carrier even though the shipper signed the cert.

Driver places a test call or Motive/Samsara message to dispatch before departure. For 172.800 loads, set the check-in cadence (typically every 2 hours plus arrival/departure at fuel and rest stops) and document missed-call escalation.
