Sample Louisiana HazMat Test Questions

Question 1

What is the primary safety purpose of properly packaging hazardous materials?

  1. A To display the vehicle's required placards
  2. B To contain the material safely
  3. C To simplify the driver's route planning
  4. D To eliminate the need for shipping papers

Correct answer: B – To contain the material safely

Hazardous materials packaging is intended to keep the product contained during normal transportation conditions. Proper containment protects drivers, other people, property, and the environment from exposure. Labels, markings, placards, and shipping papers perform the separate function of communicating the hazard.

Into how many numbered hazard classes are hazardous materials organized?

  1. A Seven
  2. B Nine
  3. C Twelve
  4. D Thirty-two

Correct answer: B – Nine

Hazardous materials are organized into nine numbered hazard classes. Several classes are divided further into divisions that describe more specific hazards, such as flammable gas or poisonous gas. Those divisions do not increase the total number of primary hazard classes.

Question 3

Which motor-vehicle shipment may qualify for an exception from the shipper's certification requirement?

  4. D A non-waste shipment transported by the shipper as a private carrier and not being reshipped or transferred

Correct answer: D – A non-waste shipment transported by the shipper as a private carrier and not being reshipped or transferred

Federal regulations generally require the person offering hazardous materials to certify that the shipment is properly prepared. Except for hazardous waste, certification is not required when the shipper transports the material as a private carrier, unless it is being reshipped or transferred between carriers. The Louisiana manual also identifies carrier-supplied cargo tanks as another motor-vehicle exception.

  4. D UN1789, 8, Hydrochloric acid, PG II

The basic description begins with the identification number, followed by the proper shipping name and hazard class or division. The packing group, when assigned, follows those elements and is shown in Roman numerals. Additional required information may appear before or after the basic description as permitted by the regulations.

The CDL manual directs the driver to remove all explosives before separating vehicles involved in a collision. The explosives are to be placed at least 200 feet from the vehicles and occupied buildings. The driver must also warn others, keep bystanders away, prohibit smoking or open flames, and remain at a safe distance.

A bill of lading, shipping order, or manifest is an example of what type of document?

  1. A A vehicle inspection report
  2. B An emergency response guide
  3. C An optional cargo receipt
  4. D A shipping paper

Correct answer: D – A shipping paper

Shipping orders, bills of lading, and manifests are common forms of shipping papers. When hazardous materials are transported, the shipping paper provides the required description of each regulated material. It must be prepared and kept where the driver and emergency responders can locate it as required.
