Connecticut CDL: Hazardous Materials Practice Test

Not quite. The answer is UN 1090, Acetone, 3

The basic description of hazardous materials includes the identification number, the proper shipping name, the hazard class or division, and the packing group, if any, in that order. The packing group is a grouping by the degree of danger as shown for that hazardous material in the Hazardous Materials Table. Packing Group I indicates great danger; Packing Group II, medium danger; and Packing Group III, minor danger. (The answer choices for this question do not include the packing group.)

Not quite. The answer is The shipper

The shipping paper describes the hazardous material and its quantity, among other things. The shipper must fill out the shipping paper because the shipper packages the material. Only the shipper knows exactly what's inside the package. Except in an emergency, no one else should open the package to see what's inside until the package is delivered to the receiver.

Not quite. The answer is 4 psi.

One of the most common types of cargo tanks is the DOT-406, typically used for fuel delivery. A semi-truck with a DOT-406 mounted to the semitrailer is commonly called a "gasoline truck." DOT-406 tanks have a low maximum allowable working pressure (MAWP) of 4 psi.

Not quite. The answer is Radioactive Materials

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. Class 7 materials are radioactive materials. These include radioactive metals, ionization smoke detectors that contain the isotope Americium 241, medical and scientific isotopes, and spent nuclear fuel.

Not quite. The answer is 3 inches

Placards must be displayed so they can be easily read from the directions that they face. They must be kept clean, undamaged, unobscured by tarpaulins or other objects, and positioned at least three inches from any other markings.

Not quite. The answer is you will have to use placards.

The hazard classes listed in Placard Table 1 are particularly hazardous. These include mass explosives (1.1) and toxic gases (2.3). You must use placards to carry any amount of the hazard classes in Placard Table I.

Not quite. The answer is On the shipping papers and on the packages

The two main places where you must keep the hazardous material identification numbers are on your shipping papers and on the packages, because these are the places that emergency personnel have been trained to check immediately.

Not quite. The answer is On the driver's seat whenever you are out of the vehicle

Your shipping papers for hazardous materials must be visible and accessible to emergency personnel at all times, including when you are out of the vehicle. Therefore, whenever you are away from your vehicle, they must be left on the driver's seat, within easy reach in case of an emergency.

Not quite. The answer is All of the above

The hazardous materials regulations (HMR) don't just apply to the movement of hazmat. These regulations also apply to those operations that are considered incidental to the movement of hazmat. Such operations include loading and unloading, blocking and bracing, and segregating hazmat from incompatible cargo. For bulk packaging transported by road, the HMR also apply to the transloading (transfer) of hazmat from one bulk package to another; and to the emptying of hazmat from the bulk package, upon delivery to the receiver.

Not quite. The answer is the shipper.

The shipper packs the hazardous materials for transport. The shipper must determine the correct identification number and record it on the packages and the shipping papers. (In the event of an accident, first responders are trained to look first at the packages and the shipping papers for the identification number.)

Not quite. The answer is a place that has been approved for parking unattended vehicles carrying explosives.

The term "safe haven" refers to a place created by local authorities where you can safely leave your truck unattended by you while it holds explosive materials. While the rules for managing safe havens may vary by jurisdiction, the safe haven may be secured by warning signs and gates and patrolled by watch personnel who are trained in how to handle the dangers of hazardous materials. This solves a trucking dilemma that has often led drivers to make risky decisions, such as driving through the night so that they could stay with their loads.

Not quite. The answer is The identification number

The hazardous material identification number is a four-digit code used by first responders to identify the material, should an accident occur. The identification number must appear first on the shipping paper as part of the shipping description.

Not quite. The answer is within 25 feet.

Whenever you load or unload a cargo tank, there must be a qualified person no farther than 25 feet away who can observe the process and intervene if necessary. This person must know the hazards and what to do in case of an emergency. He or she must also be authorized to move the cargo tank and able to do so if necessary.

Not quite. The answer is Reflective triangles

Ideally, you should not risk exposing any type of hazardous material to flame, but especially Division 1.1, 1.2, or 1.3 (explosives), Division 2.1 (flammable gases), or Division 3 (flammable liquids). These can be so volatile that they should not be exposed to any heat source, not even a cargo heater. Set out warning triangles as explained in the section "Communicating Your Presence" in the Connecticut Commercial Driver License Manual.

Not quite. The answer is The material is subject to the HMR only when offered or intended for transport by air unless it is a hazardous substance or hazardous waste.

Column 1 tells which shipping mode(s) the entry affects and other information concerning the shipping description. Six different symbols may appear in Column 1 of the table. (A) Means the hazardous material described in Column 2 is subject to the HMR only when offered or intended for transport by air unless it is a hazardous substance or hazardous waste.

Not quite. The answer is have their drivers text their locations.

To communicate the risk of hazardous materials, regulations require shippers to put placards on trucks, put hazard warning labels on packages, provide proper shipping papers, and supply emergency response information. Regulations don't usually require regular texting. In fact, in many states, texting on a handheld cell phone while driving is illegal.

Not quite. The answer is $50,000

If there is an incident involving hazardous materials, you or your employer must call the National Response Center if any of the following have occurred: death or injury requiring hospitalization; more than $50,000 in estimated property damage; evacuation of the general public for more than one hour; the closure of a major road for more than one hour; damage to or spillage of radioactive substances; damage to or spillage of infectious agents; or any other incident that the carrier believes is dangerous enough to be reported.

Not quite. The answer is Only when it is a non-placarded material

You must have a hazardous materials endorsement on your CDL to drive a vehicle that is placarded for hazardous materials. However, not all packages of hazardous materials require placarding your vehicle. For example, relatively small quantities of consumer-grade chemicals such as drain openers and bleaches may be exempt. Federal regulation 49 CFR 172.500 exempts certain amounts and types of hazardous materials from placarding, but states may impose more stringent requirements. Check with the Connecticut Department of Transportation.

Not quite. The answer is 2

A material’s hazard class reflects the risks associated with it. There are nine hazard classes. Class 2 includes various gases: flammable gases (2.1), such as propane; non-flammable gases (2.2), such as helium; and toxic gases (2.3), such as compressed fluorine.
