Mississippi CDL HazMat Endorsement Test study plan

Mississippi CDL HazMat Endorsement Test · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Week 2

Hazard classes and divisions: explosive, gas, flammable liquid, flammable solid, oxidizer, toxic, radioactive, corrosive, and miscellaneous & Hazard communication: shipping papers, placarding, marking, labels, and emergency response information

  • Sort 40 common materials (for example gasoline, propane, anhydrous ammonia, sulfuric acid, pool chlorine, fireworks, lithium batteries, and oxygen) into class, division, and packing group where applicable.

  • Match each placard to its class and state the quantity thresholds that trigger placarding, including the 1,001-pound aggregate rule and the table 2 exceptions.

  • Describe the marking requirements for a non-bulk package, including the UN number and proper shipping name, and explain when labels are required in addition to placards.

Your checkpoint

A completed shipping-paper worksheet with 10 entries decoded field by field, plus a placard-to-class matching sheet scored at 90%.

Week 3

Hazard communication: shipping papers, placarding, marking, labels, and emergency response information & Hazardous materials regulations, definitions, and operational requirements (49 CFR Parts 171-180; HM endorsement rules)

  • State the four required elements of emergency response information that must accompany a hazmat shipping paper and identify where it may be kept in the cab.

  • Explain the shipper's and carrier's responsibilities for the emergency response telephone number, including when a third-party registrant may be used.

  • List the situations in which a shipping paper may be kept in a location other than within the driver's immediate reach and the conditions that apply while the vehicle is moving.

  • Describe how to recognize and use the Emergency Response Guidebook: yellow-bordered number index, blue-bordered name index, orange guide pages, and green table for isolation and protective action distances.

Your checkpoint

A written walkthrough using the ERG structure to look up three assigned materials and record guide number, isolation distance, and protective action distance for each.

Week 4

Vehicle inspection, loading, unloading, segregation, and cargo securement for hazardous materials & Special hazmat cargo: bulk tanks, cargo tanks, portable tanks, and division 2.3/6.1 toxic-by-inhalation materials

  • Perform and document a pre-trip inspection specific to a hazmat vehicle, covering tank condition, valves, vents, grounding, placards, labels, and leakage evidence.

  • Explain loading and segregation rules that keep incompatible materials apart, and identify at least four incompatible pairs that must never share a load.

  • Describe securement requirements for bulk and non-bulk hazmat loads, including the working load limit rule and the number of tiedowns needed for a given load length.

  • Distinguish among a cargo tank, a portable tank, and a bulk packaging, and state the marking and specification plate information a driver should verify before loading.

Your checkpoint

A completed pre-trip inspection checklist for a cargo tank with 20 or more line items, plus a segregation worksheet showing four incompatible pairs correctly separated.

Week 5

Driving and parking rules for hazmat: routes, tunnels, railroad crossings, fueling, and attendance & Tunnel, bridge, and railroad-highway crossing restrictions; hazardous materials routing

  • List the parking rules for placarded loads, including attendance requirements, the distance from buildings and roadways, and when a secure facility may substitute for attendance.

  • Explain fueling restrictions for a placarded vehicle, including engine-off requirements, attendance at the nozzle, and the ban on fueling with passengers aboard.

  • Describe railroad-highway crossing procedures for a placarded load: stopping distance, looking and listening, gear selection, and when a flagger or escort is required.

  • Identify the routing restrictions that apply to hazmat, including designated routes, tunnel restrictions, and bridge or weight-posted structures, and explain who sets them.

Your checkpoint

A route plan for one hypothetical placarded trip that marks every railroad crossing stop, tunnel restriction, and designated parking location on the route.

Week 6

Incident reporting, emergency response procedures, and security awareness & Special hazmat cargo: bulk tanks, cargo tanks, portable tanks, and division 2.3/6.1 toxic-by-inhalation materials

  • List the incidents that must be reported to the National Response Center, including the reportable quantity triggers for hazardous substances and the criteria for a hazardous material release.

  • Write out the information a driver must provide when reporting a hazmat incident, including material identity, quantity, location, injuries, and carrier contact.

  • Describe the immediate response steps after a leak or spill: secure the scene, keep people upwind, notify authorities, and avoid contact with toxic-by-inhalation materials.

  • Explain the special handling rules for Division 2.3 and 6.1 toxic-by-inhalation materials, including the hazard zone designations and the additional shipping paper requirements.

Your checkpoint

A written incident report for a simulated chlorine release that includes all required notification elements and a correct hazard zone assignment.

Week 7

Incident reporting, emergency response procedures, and security awareness & Hazmat endorsement application, TSA security threat assessment, and disqualification/background requirements
