Question 1Hazardous Materials Regulations, Definitions, and Driver Responsibilities

While driving a placarded load, where must the driver keep the shipping papers?

  1. Left at the terminal and faxed to the receiver in advance
  2. Folded in the glove box so it stays hidden from public view
  3. Locked inside the cargo area with the packages it describes
  4. In clear view and within the driver's reach Correct answer.

Explanation

Federal rules require hazmat shipping papers to be readily accessible to the driver during transport, typically in a pouch on the driver's door or in clear view within reach. Someone entering the cab, such as an inspector, must be able to see and take the papers immediately. Keeping them locked in the cargo area or off the vehicle defeats that purpose.

Question 2Hazardous Materials Regulations, Definitions, and Driver Responsibilities

What kind of telephone number must appear on a shipping paper for a hazardous material shipment?

  1. A 24-hour number monitored during transport Correct answer.
  2. The driver's personal cellphone number
  3. The nearest state police non-emergency number
  4. The shipper's main office line during weekday business hours

Explanation

The emergency response telephone number on a hazmat shipping paper must be monitored at all times while the material is in transportation, including evenings and weekends. A business-hours line fails when an incident happens at night. The number must reach someone able to give response information.

Question 3Hazardous Materials Regulations, Definitions, and Driver Responsibilities

A truck carries 1,200 pounds of a single Table 2 hazardous material and no other hazardous material. What placarding is required?

  1. None, because Table 2 materials never require placards
  2. Placards, but only if the material is also a marine pollutant
  3. Placards for that hazard class, because the load is 1,001 pounds or more Correct answer.
  4. None, because placards are needed only above 5,000 pounds

Explanation

For Table 2 hazard classes, placards are required when the aggregate gross weight of all Table 2 materials in the load is 1,001 pounds or more. A 1,200-pound load of one Table 2 material crosses that threshold, so the matching placard is required on both sides and both ends.

Question 4Hazardous Materials Regulations, Definitions, and Driver Responsibilities

Under what condition may a driver display the DANGER placard instead of separate hazard class placards?

  1. When any amount of a Table 1 material is aboard
  2. When the load contains only one hazard class above 1,001 pounds
  3. When the shipment is a single package of a Division 6.1 material
  4. When 1,001 pounds or more of two or more Table 2 classes are loaded Correct answer.

Explanation

The DANGER placard is an option for loads that reach 1,001 pounds or more in the aggregate and involve two or more Table 2 hazard classes, when no Table 1 material is present. It substitutes for the individual class placards for those Table 2 materials.

Question 5Hazardous Materials Regulations, Definitions, and Driver Responsibilities

A vehicle carries one 10-pound package of a Table 1 hazardous material. What placarding applies?

  1. No placard, since the load is under 1,001 pounds
  2. No placard, since placards apply only to bulk packages
  3. The Table 1 placard is required for any quantity Correct answer.
  4. A placard is required only if the package weighs 100 pounds or more

Explanation

Table 1 materials are placarded for any quantity, with no weight threshold. The 1,001-pound aggregate rule applies only to Table 2 materials. A single small package of a Table 1 material therefore still requires its placard.

Question 6Hazardous Materials Regulations, Definitions, and Driver Responsibilities

What is the Emergency Response Guidebook used for?

  1. To find initial response actions for a material by guide number Correct answer.
  2. To certify drivers for the hazardous materials endorsement
  3. To calculate freight charges for hazardous shipments
  4. To record a driver's hours of service on hazmat runs

Explanation

The guidebook lets responders and drivers look up a material's four-digit identification number and find a guide number with initial isolation distances and first-response precautions. It is a reference for the early stages of an incident, not a substitute for a full response plan.

Question 7Hazardous Materials Regulations, Definitions, and Driver Responsibilities

Before a state may issue a hazardous materials endorsement, the applicant must complete which of the following?

  1. A fingerprint-based TSA security threat assessment Correct answer.
  2. A commercial driving school refresher course
  3. A sponsoring carrier's written letter of recommendation
  4. A one-year probation period driving tank vehicles

Explanation

Hazmat endorsement applicants must pass a fingerprint-based security threat assessment conducted through TSA before the state can issue or renew the endorsement. The check is separate from the knowledge test and the CDL road skills test.

Question 8Hazardous Materials Regulations, Definitions, and Driver Responsibilities

While a placarded vehicle is being fueled, smoking is prohibited within what distance of the vehicle?

  1. 20 feet
  2. 15 feet
  3. 25 feet Correct answer.
  4. 10 feet

Explanation

Federal rules prohibit smoking or carrying a lighted cigarette within 25 feet of a placarded vehicle while it is being fueled. The same distance applies to open flames and other ignition sources around the fueling operation.

Question 9Hazardous Materials Regulations, Definitions, and Driver Responsibilities

For a placarded vehicle that must be attended, the driver is considered to be attending it when the driver is where?

  1. Within 100 feet with the vehicle in unobstructed view Correct answer.
  2. Within one mile and reachable by cellphone
  3. Within 25 feet with the keys left in the ignition
  4. Inside the cab with the doors closed and locked

Explanation

Attendance means staying close enough and positioned so the vehicle is in plain sight, which is defined as within 100 feet and in unobstructed view. Being inside the cab asleep, or far away with only phone contact, does not satisfy the requirement.

Question 10Hazardous Materials Regulations, Definitions, and Driver Responsibilities

Why must cyanides and acids be kept apart when loading a mixed hazardous materials shipment?

  1. They cancel each other's placard requirements
  2. They can react together to release a deadly gas Correct answer.
  3. They melt the protective lining of cargo tanks
  4. They ignite spontaneously when exposed to sunlight

Explanation

Mixing cyanides with acids produces hydrogen cyanide, a highly toxic gas, which is why segregation rules keep them separated in a load. Segregation prevents dangerous chemical reactions if packages leak or break in transit.

Question 11Hazardous Materials Regulations, Definitions, and Driver Responsibilities

A driver hauling a placarded load approaches a tunnel posted with a hazardous materials prohibition sign. What should the driver do?

  1. Park on the shoulder and wait until the sign is removed
  2. Stop and wait for a police escort through the tunnel
  3. Proceed slowly through the tunnel with hazard flashers on
  4. Use the designated hazardous materials route around the tunnel Correct answer.

Explanation

Where a tunnel or road segment is closed to hazardous materials, the driver must follow the marked alternate route designated for hazmat traffic. Ignoring the restriction can mean a citation and a serious risk in a confined space.

Question 12Hazardous Materials Regulations, Definitions, and Driver Responsibilities

Class 3 covers flammable liquids, which are liquids with a flash point at or below what temperature?

  1. 32°F (0°C)
  2. 140°F (60°C) Correct answer.
  3. 100°F (38°C)
  4. 212°F (100°C)

Explanation

A flammable liquid is one with a flash point of not more than 60°C (140°F). Materials above that flash point but below 200°F fall in the combustible liquid range and are handled differently. Flash point is the temperature at which a liquid gives off enough vapor to ignite.

Question 13Hazardous Materials Regulations, Definitions, and Driver Responsibilities

A package marked Division 1.1 contains a material with what primary hazard?

  1. A mass explosion hazard Correct answer.
  2. A projection hazard with no mass explosion
  3. A minor fire hazard with no blast risk
  4. A moderate fire hazard confined to the package

Explanation

Division 1.1 covers explosives that present a mass explosion hazard, meaning the whole quantity can detonate essentially at once. The other divisions describe lesser explosive hazards such as projection, minor fire, or modest blast effects.

Question 14Hazardous Materials Regulations, Definitions, and Driver Responsibilities

During a pre-trip inspection a driver finds a package that is leaking. What should the driver do first?

  1. Keep people away and warn them of the hazard Correct answer.
  2. Continue the trip and report the leak at delivery
  3. Load the package last so it rides near the door
  4. Wipe up the spill with rags kept in the cab

Explanation

A leaking hazardous materials package is an emergency: the driver should avoid contact, keep others away, and warn people nearby before notifying proper authorities. Cleaning up an unknown material without training or protective equipment can cause injury.

Question 15Hazardous Materials Regulations, Definitions, and Driver Responsibilities

On a shipping paper, the basic description of a hazardous material must appear in which order?

  1. Shipping name, hazard class, UN number, packing group Correct answer.
  2. Hazard class, packing group, UN number, shipping name
  3. UN number, packing group, shipping name, hazard class
  4. Packing group, shipping name, hazard class, UN number

Explanation

The required sequence is the proper shipping name, hazard class or division, UN identification number, and packing group. Following the standard order lets responders and inspectors read the entry quickly under pressure.

Question 16Hazardous Materials Regulations, Definitions, and Driver Responsibilities

Where must hazardous materials placards be displayed on a vehicle?

  1. On the rear and the driver's side only
  2. On both sides and both ends of the vehicle Correct answer.
  3. On the roof and both sides
  4. On the front bumper and the roof

Explanation

Placards must be placed so they are visible from both sides and from both the front and rear of the vehicle. This lets responders and other drivers identify the hazard from any approach direction.

Question 17Hazardous Materials Regulations, Definitions, and Driver Responsibilities

What must the driver do with the engine while refueling a placarded vehicle?

  1. Run it at high idle to speed the transfer
  2. Keep it running so the air brakes stay released
  3. Leave it idling to keep the fuel pump running
  4. Shut it off during the fueling operation Correct answer.

Explanation

Federal rules require the engine to be shut off while a placarded vehicle is being fueled. A running engine provides an ignition source around fuel vapors and also allows the vehicle to move unexpectedly. The engine is restarted only after fueling is complete and the nozzle is stowed.

Question 18Hazardous Materials Regulations, Definitions, and Driver Responsibilities

When a shipping paper covers both hazardous and non-hazardous materials, how must the hazardous entries be shown?

  1. Removed before the paper is handed to the driver
  2. Listed first or otherwise distinguished from the rest Correct answer.
  3. Written into a separate logbook kept in the sleeper
  4. Repeated on a second page signed by the loader

Explanation

Hazardous material entries must be listed before the non-hazardous entries, or if they are mixed in, they must be distinguished, for example by highlighting or a contrasting color. The point is that hazardous items can be located at a glance.

Question 19Hazardous Materials Regulations, Definitions, and Driver Responsibilities

A driver must park a vehicle carrying Division 1.1 explosives. The vehicle may not be parked within what distance of the roadway?

  1. 25 feet
  2. 50 feet
  3. 5 feet Correct answer.
  4. 10 feet

Explanation

A vehicle carrying Division 1.1, 1.2, or 1.3 explosives may not be parked within 5 feet of the traveled portion of the roadway. Separating the vehicle from traffic reduces the chance that a passing vehicle will strike the load.

Question 20Hazardous Materials Regulations, Definitions, and Driver Responsibilities

Before crossing a railroad track, a driver carrying a placarded load must do which of the following?

  1. Slow to 25 mph and cross without stopping
  2. Stop, look both ways, and cross only when clear Correct answer.
  3. Sound the horn and proceed at the normal speed limit
  4. Cross only when a flagman is on duty at the crossing

Explanation

Drivers of placarded vehicles must stop before the tracks, look and listen in both directions, and proceed only when no train is approaching. The stop applies even at crossings that other traffic may cross without stopping.

Question 21Hazardous Materials Regulations, Definitions, and Driver Responsibilities

A driver discovers fire in the cargo area of a placarded load. What is the appropriate action?

  1. Stop, move away, and keep others back Correct answer.
  2. Open the cargo doors to let the smoke out
  3. Drive quickly to the nearest fire station
  4. Fight the fire from inside the cargo area

Explanation

For a cargo fire involving hazardous materials, the driver should stop, get away from the vehicle, and keep other people away while emergency responders are notified. Opening doors or fighting the fire can expose the driver to toxic fumes or a sudden flare-up.

Question 22Hazardous Materials Regulations, Definitions, and Driver Responsibilities

What type of hazard does Class 8 identify?

  1. Materials that are toxic only when inhaled
  2. Materials that burn readily below 100°F
  3. Materials that corrode skin or metal Correct answer.
  4. Materials that give off harmful radiation

Explanation

Class 8 is the corrosive class: materials that cause visible destruction or irreversible damage to skin, or that corrode steel or aluminum. Acids and bases are common examples. Radiation, flammability, and toxicity belong to other classes.

Question 23Hazardous Materials Regulations, Definitions, and Driver Responsibilities

A package spills and releases an amount equal to or greater than its reportable quantity. What must the driver do?

  1. Record it in the logbook at the end of the trip instead
  2. Report the release promptly to the proper authorities Correct answer.
  3. Wait for the shipper to decide whether reporting is needed
  4. Nothing, because reportable quantities apply only to water shipments

Explanation

A release at or above the reportable quantity is a reportable incident that must be reported promptly to the designated authorities, such as the National Response Center. The obligation is immediate and rests with the person in possession of the material, including the driver.

Question 24Hazardous Materials Regulations, Definitions, and Driver Responsibilities

Division 6.2 covers which type of hazardous material?

  1. Oxidizing liquids
  2. Radioactive material
  3. Infectious substances Correct answer.
  4. Flammable gases

Explanation

Division 6.2 is the infectious substance category, covering materials known or reasonably expected to contain pathogens that can cause disease in humans or animals. Flammable gases are Class 2, oxidizers are Class 5.1, and radioactive material is Class 7.

Question 25Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

When a hazardous material is entered on a shipping paper, what is the required order of the basic description?

  1. Proper shipping name, packing group, UN identification number, hazard class
  2. UN identification number, proper shipping name, hazard class, packing group Correct answer.
  3. Hazard class, proper shipping name, UN identification number, packing group
  4. Packing group, hazard class, proper shipping name, UN identification number

Explanation

The basic description follows the sequence used in the Hazardous Materials Table: identification number first (preceded by UN or NA), then the proper shipping name, then the hazard class or division, and finally the packing group. A few narrow domestic variations exist, but the standard sequence is identification number, name, class, packing group.

Question 26Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

Who is responsible for furnishing the required placards to the motor carrier for a hazardous materials shipment?

  1. The person offering the shipment to the carrier Correct answer.
  2. The receiving warehouse
  3. The driver of the vehicle
  4. The consignee at the destination

Explanation

The offeror (shipper) must supply the placards to the motor carrier unless the carrier already has the needed placards. The carrier then has the duty to affix them to the vehicle.

Question 27Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

A placard used to communicate a hazard to emergency responders has which shape?

  1. A diamond, mounted on point Correct answer.
  2. An upright square
  3. A triangle
  4. A circle

Explanation

Placards are square-on-point diamonds, matching the shape of hazard labels so responders recognize them instantly. The standard size is about 10 3/4 inches on each side.

Question 28Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

While the vehicle is moving, where must the shipping papers for a placarded load be kept?

  1. Locked inside the cargo area with the freight
  2. Filed at the carrier's terminal office
  3. Mailed ahead to the consignee before departure
  4. Within the driver's reach in the cab Correct answer.

Explanation

The shipping paper must be readily visible to anyone entering the driver's compartment, or kept in a holder mounted inside the driver's door. Keeping it within reach lets the driver hand it to an inspector or emergency responder immediately.

Question 29Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

The letters "RQ" placed before a proper shipping name on a shipping paper indicate that the material is:

  1. A hazardous substance in a reportable quantity Correct answer.
  2. A shipment that must be kept refrigerated
  3. A radioactive material
  4. A limited quantity package

Explanation

RQ stands for reportable quantity and identifies a hazardous substance shipped in an amount that triggers reportable-quantity requirements. The letters are placed directly before the proper shipping name on the shipping paper.

Question 30Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

On a hazardous materials shipping paper, what must accompany the emergency response telephone number?

  1. The driver's personal cell phone number
  2. The name of the agency or a contract number Correct answer.
  3. The vehicle's license plate number
  4. The consignee's delivery address

Explanation

The emergency response telephone number must be accompanied by the name of the person or agency able to provide the information, or by a contract number. The number must be monitored at all times while the material is in transportation.

Question 31Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

Which words appear on the hazard label for a Class 3 material?

  1. CORROSIVE
  2. FLAMMABLE LIQUID Correct answer.
  3. SPONTANEOUSLY COMBUSTIBLE
  4. OXIDIZER

Explanation

Class 3 covers flammable and combustible liquids, and its label carries the words FLAMMABLE LIQUID on a red background. Each hazard class label has its own prescribed text and color scheme.

Question 32Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

Placards on a transport vehicle carrying hazardous materials must be displayed:

  1. On both sides and both ends Correct answer.
  2. On both sides only
  3. On the front and the left side
  4. On the rear only

Explanation

Placards must be visible from both sides and both ends of the transport vehicle so that responders approaching from any direction can identify the hazard. Bulk packagings such as cargo tanks carry their own placarding as well.

Question 33Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

At what aggregate gross weight do Table 2 hazardous materials require placards on a transport vehicle?

  1. 2,205 pounds or more
  2. Any quantity, no matter how small
  3. 500 pounds or more
  4. 1,001 pounds or more Correct answer.

Explanation

Table 2 materials require placards when the aggregate gross weight of all Table 2 materials in the vehicle is 1,001 pounds (454 kg) or more. Below that threshold, placards are not required for Table 2 materials.

Question 34Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

For domestic transportation, when may the DANGEROUS placard be used?

  1. In place of any placard, including Table 1 placards
  2. In place of the Table 2 placards Correct answer.
  3. Only on cargo tanks
  4. Only when no hazardous materials are on board

Explanation

The DANGEROUS placard may substitute for the specific Table 2 placards when those materials require placarding domestically. It may never be used in place of a placard required for a Table 1 material.

Question 35Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

A material is a toxic inhalation hazard in Hazard Zone A. Which placard must the vehicle display?

  1. POISON INHALATION HAZARD Correct answer.
  2. POISON
  3. DANGEROUS
  4. No placard is required for small quantities

Explanation

Inhalation hazards in Hazard Zones A and B require the POISON INHALATION HAZARD placard and are Table 1 materials, so placards are required regardless of quantity. The DANGEROUS placard cannot be substituted for a Table 1 requirement.

Question 36Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

How long must the person who provides a hazardous materials shipping paper keep a copy of it?

  1. 1 year
  2. 5 years
  3. 6 months
  4. 2 years Correct answer.

Explanation

The offeror must retain a copy of the shipping paper for 2 years after the material is accepted by the initial carrier. Training records are kept longer, but shipping paper retention is 2 years.

Question 37Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

A non-bulk package containing a hazardous material generally must be marked with:

  1. Only the shipper's name
  2. The proper shipping name and UN identification number Correct answer.
  3. Only the hazard class number
  4. The packing group alone

Explanation

Non-bulk packages must show the proper shipping name and the UN identification number, along with any other marking the material requires. Limited quantity and small package exceptions can modify this, but the general rule is name plus identification number.

Question 38Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

For a Class 1 explosive, what must immediately follow the hazard class in the shipping description?

  1. The flash point of the material
  2. The packing group only
  3. The reportable quantity
  4. The compatibility group letter Correct answer.

Explanation

Explosives are described with the division followed by the compatibility group letter, such as "1.1D." The letter tells responders which explosives may be stored or handled together.

Question 39Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

After a vehicle is unloaded and no longer contains hazardous materials, the placards must be:

  1. Removed or obscured Correct answer.
  2. Left in place until the next hazmat load
  3. Covered with tape and dated
  4. Replaced with DANGEROUS placards

Explanation

Placards may not remain displayed on a vehicle that no longer contains the hazardous material, so they must be removed or otherwise obscured. Leaving them up misleads responders and misstates the load.

Question 40Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

What must the shipper provide on a hazardous materials shipping paper?

  1. A written statement, signed by the carrier, confirming that every package was inspected and approved
  2. A signed certification of accurate description and proper preparation Correct answer.
  3. A notarized signature from the driver who will haul the load
  4. A statement listing the gross weight and dimensions of every package

Explanation

The offeror signs a certification stating that the shipment is fully and accurately described, classified, packaged, marked, labeled, and placarded as required. This certification places responsibility for the shipment's condition on the shipper.

Question 41Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

Placards for Table 1 hazardous materials are required:

  1. Only when the vehicle crosses state lines
  2. Only at 1,001 pounds or more
  3. At any quantity Correct answer.
  4. Only when the material is in bulk packaging

Explanation

Table 1 materials, which include high-hazard items such as certain inhalation hazards and dangerous when wet materials, must be placarded regardless of the quantity loaded. The 1,001-pound threshold applies only to Table 2.

Question 42Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

In the Hazardous Materials Table, which column shows the hazard class or division of a material?

  1. Column 8
  2. Column 3 Correct answer.
  3. Column 1
  4. Column 5

Explanation

Column 3 of the Hazardous Materials Table gives the hazard class or division for each entry. Column 2 contains the proper shipping name and column 4 contains the identification number.

Question 43Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

A package bears a FLAMMABLE LIQUID label and a subsidiary CORROSIVE label. Which placards must the vehicle display?

  1. No placards, because the material is in non-bulk packaging
  2. Both the FLAMMABLE and CORROSIVE placards
  3. Only the subsidiary CORROSIVE placard
  4. Only the placard for the primary hazard, FLAMMABLE Correct answer.

Explanation

Placarding follows the primary hazard class of the material; subsidiary hazard placards are generally not required. Non-bulk packaging does not by itself exempt a shipment from placarding once the quantity threshold is met.

Question 44Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

When an identification number appears on a shipping paper, how must it be shown?

  1. Preceded by the letters PG
  2. Enclosed in parentheses
  3. Preceded by UN or NA Correct answer.
  4. Written with no prefix at all

Explanation

The four-digit identification number must be preceded by the letters UN (for international entries) or NA (for North American entries). This format lets responders recognize the number as an identification number rather than a quantity or code.

Question 45Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

A vehicle carries 500 pounds of a Table 1 material and 2,000 pounds of a Table 2 material. Which placards must be displayed?

  1. No placards, because neither material reaches 1,001 pounds alone
  2. Only the DANGEROUS placard, which covers both materials
  3. The Table 1 placard plus the Table 2 placard or DANGEROUS Correct answer.
  4. Only the Table 2 placards, because the total exceeds 1,001 pounds

Explanation

Table 1 materials must be placarded at any quantity, so the 500-pound portion alone requires its specific placard. Because the Table 2 portion exceeds 1,001 pounds, its placards are also required, though DANGEROUS may substitute for those Table 2 placards.

Question 46Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

A tank car has been emptied of a hazardous material but has not been cleaned or purged. What marking is required?

  1. No marking at all, because the tank car is now empty of product
  2. The UN number alone on an orange panel
  3. EMPTY - NO HAZARD
  4. RESIDUE: LAST CONTAINED and the proper shipping name Correct answer.

Explanation

A tank car that has been emptied but not cleaned and purged still contains a hazardous residue, so it must be marked with RESIDUE: LAST CONTAINED followed by the proper shipping name. The residual material keeps the car regulated until it is cleaned.

Question 47Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

A shipment consists entirely of packages bearing the limited quantity marking. What placarding is required?

  1. Only the DANGEROUS placard
  2. No placards are required Correct answer.
  3. Placards for each hazard class present in the load
  4. Only the FLAMMABLE placard

Explanation

Materials packaged as limited quantities are excepted from the placarding requirements, so the vehicle needs no placards even though the packages carry hazard information. The packages must instead bear the limited quantity marking.

Question 48Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

Where must a hazard label be placed on a non-bulk package?

  1. On the same surface as the proper shipping name marking Correct answer.
  2. Anywhere on the package, including the bottom surface
  3. On a tag wired to the outside of the package
  4. Inside the package, with a duplicate on the outside

Explanation

A label must be affixed to the package surface, other than the bottom, and located on the same surface as and near the proper shipping name marking when the package's size and shape allow. This keeps the hazard and the identification information together.

Question 49Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

A toxic material in Hazard Zone B is offered for shipment. How is the inhalation hazard shown on the shipping paper?

  1. By attaching the placard to the shipping paper
  2. By the letters RQ before the proper shipping name
  3. By the UN identification number and packing group in the description
  4. By a Poison-Inhalation Hazard notation with the hazard zone Correct answer.

Explanation

The shipping paper must carry the words Poison-Inhalation Hazard or Toxic-Inhalation Hazard together with the hazard zone, entered right after the basic description. Responders rely on that notation because the placard alone does not show the hazard zone.

Question 50Hazard Communication: Shipping Papers, Marking, Labeling, and Placarding

Which words appear on the hazard label for a Division 4.3 material?

  1. DANGEROUS WHEN WET Correct answer.
  2. OXIDIZER
  3. FLAMMABLE SOLID
  4. SPONTANEOUSLY COMBUSTIBLE

Explanation

Division 4.3 covers materials that give off a flammable gas when they come into contact with water, so the required label text is DANGEROUS WHEN WET. The label also shows the class number 4 in its lower corner and a flame symbol.
