Hazmat basics1 of 20
The answer
Answer: B. The common reference for these regulations is 49 CFR 171 to 180. Parts 1 to 50 of title 40 deal with other subject matter, parts 380 to 399 of title 49 cover motor carrier safety, and state codes do not hold these federal rules, so look in 49 CFR 171 to 180 for the hazmat regulations.

Hazmat basics2 of 20
The answer
Answer: B. To get the endorsement you must pass a written test about the regulations and requirements. A tank vehicle or passenger endorsement covers different hazards, and a state permit alone is not the federal requirement, so a CDL with the hazardous materials endorsement is needed whatever the vehicle size.

Hazard classes3 of 20
The answer
Answer: B. The nine classes are shown in Figure 9.1, with divisions in some classes. Five, twelve and twenty are not the number of classes, since the manual describes nine hazard classes, and some of them are divided into divisions for more specific hazards.

Hazard classes4 of 20
The answer
Answer: B. Acetone is another example given for flammable liquids. Compressed gases, corrosives and oxidizers are separate classes with their own hazards, whereas gasoline is a flammable liquid in Class 3, and acetone is another example the manual gives. Flammable liquids give off vapor that burns at ordinary temperatures, which is why they sit in their own class.

Shipping papers5 of 20
The answer
Answer: A. Shipping orders, bills of lading and manifests are all shipping papers. A fuel receipt, a parking permit and a driver's logbook describe the trip or the truck, not the cargo, whereas a bill of lading is a shipping paper listing what is carried.

Shipping papers6 of 20
The answer
Answer: A. When you are out of the vehicle, leave them on the driver's seat. The glove box, the sleeper berth and under the seat put the papers out of reach or sight if you are injured, so keep them in a door pouch or in clear view where a rescuer can find them quickly.

Shipping papers7 of 20
The answer
Answer: C. After an accident you may be injured and unable to communicate the hazards. Invoices, scale counts and pay checks are not the reason, because after a crash you may be unable to speak, so the papers tell firefighters and police what the load is and how to protect themselves.

Marking labeling8 of 20
The answer
Answer: B. If the label will not fit, the shipper may put it on a tag securely attached to the package. Round stickers with the carrier's name, barcodes and plates with the shipper's address do not warn of a hazard, whereas diamond-shaped hazard labels show the class at a glance.

Marking labeling9 of 20
The answer
Answer: B. An identification number may identify more than one chemical, and it is preceded by NA or UN. A seven-digit shipper code, a letter pair for the class and a package weight are not what an identification number is, since it is a four-digit code with a UN or NA prefix that responders look up.

Placarding10 of 20
The answer
Answer: A. Placards are used to warn others of hazardous materials. Cab reminders, license stamps and tags on shipping papers are not placards, which are signs on the outside of the vehicle and bulk packages that show other people the hazard class.

Placarding11 of 20
The answer
Answer: B. Placards must be readable from all four directions. Two placards, six placards or one on the door would leave some directions without a warning, so a placarded vehicle needs at least four, one on the front, rear and each side.

Placarding12 of 20
The answer
Answer: B. Table 1 includes Divisions 1.1, 1.2, 1.3, 2.3, 4.3 and certain 5.2, 6.1 and 7 materials. The 1,001 pound threshold, interstate trips and bulk loads relate to other table rules, whereas Table 1 materials are dangerous enough that any amount requires placards.

Loading segregation13 of 20
The answer
Answer: B. Do all you can to protect containers of hazardous materials. Hazard lights, open doors, air-line disconnection, lowered landing gear and removed keys do not secure the vehicle, so set the parking brake and make sure it will not move while the hazardous materials are handled.

Loading segregation14 of 20
The answer
Answer: D. Keep fire away and do not let people smoke nearby. Class 6, 7, 8 and 9 materials and non-flammable gases do not ignite so readily, whereas Class 1, Division 2.1 and Classes 3, 4 and 5 could burn or explode, so no smoking is allowed around them.

Driving parking routes15 of 20
The answer
Answer: A. Except for short periods needed for operations, do not park within 300 feet of a bridge, tunnel or building. Within five feet if attended, 50 feet if attended or 300 feet if lit do not match the rule, which says never park within five feet of the traveled road, and not within 300 feet of a bridge, tunnel or building except briefly.

Driving parking routes16 of 20
The answer
Answer: A. Designation of authorized safe havens is usually made by local authorities. A truck stop, a rest area and a weigh station are open to the public and could put the explosives near people, whereas a safe haven is an approved place where an unattended explosive-loaded vehicle may be parked.

Emergencies notification17 of 20
The answer
Answer: D. It is indexed by proper shipping name and hazardous materials identification number. Approved truck routes, rest stops and shipping rates are not the topic, since the ERG is a DOT guidebook used by responders to protect themselves, indexed by shipping name and identification number.

Emergencies notification18 of 20
The answer
Answer: A. Do not touch any leaking material, since many people injure themselves that way. Warning others, staying upwind and calling for help are correct responses to a spill, but eating, drinking or smoking near a leak could bring the hazard into your body or ignite it.

Endorsement tsa19 of 20
The answer
Answer: D. The State must also notify the holder at least 60 days before the endorsement expires. Every 10 years, every 20 years and once only do not fit the rule, because a State must require renewal at least every 5 years, and the holder is notified 60 days before expiry.

Endorsement tsa20 of 20
The answer
Answer: A. A national of the United States, a refugee or an asylee may also apply. A tourist visitor, an asylum applicant and a person under sixteen are not on the list, whereas lawful permanent residents may apply, as may nationals, refugees and asylees.
