For a shipment subject to the emergency-information rules, the available information gives the material's name but omits its immediate hazards to health. Is the name alone enough?
Correct answer: The immediate health-hazard information still needs to be supplied
Section 172.602(a) requires more than the material's identification: its minimum content includes immediate health hazards. The question stipulates a covered shipment and does not teach treatment or exposure-assessment procedures.

A covered shipment's emergency information describes health effects but leaves out the material's fire and explosion risks. Which assessment is correct?
Correct answer: Fire and explosion risks are also part of the required information
Section 172.602(a)(3) includes risks of fire or explosion among the minimum emergency-response information. This is a requirement to supply information, not permission for an untrained driver to fight a hazardous-material fire.

The only emergency-response information for a covered material is fixed to its package. An incident would make approaching that package unsafe. What requirement has this arrangement failed to meet?
Correct answer: The information must be available for use away from the package
Section 172.602(b)(2) requires emergency-response information to be usable away from the package. Do not approach a hazardous package just to obtain it. Current (b)(1) permits paper or electronic format; this question does not impose a paper-only rule.

A carrier uses the separate-guidance-document option for emergency information on a covered shipment. What must connect that guidance with the hazardous material described on the shipping paper?
Correct answer: A cross-reference between the shipping description and the relevant response information
Under 172.602(b)(3)(iii), the separate document must relate its emergency information to the hazardous-material description through a cross-reference. Merely having a general reference somewhere does not establish that connection.

During a covered hazardous-material trip, the carrier's required emergency information is available only in an office file that the driver cannot access promptly. What is the problem?
Correct answer: The information is not immediately accessible to the driver for an incident
Section 172.602(c)(1) requires the emergency information to be immediately accessible to the motor-vehicle driver for use in an incident. An inaccessible office copy does not meet that operational need.

A facility holds covered hazardous materials in storage incidental to transportation. The required information is locked in an office unavailable to the personnel present. What needs to change?
Correct answer: The information must be immediately accessible to facility personnel
Section 172.602(c)(2) requires the facility operator to maintain the required information whenever the material is present and in a location immediately accessible to facility personnel during an incident. Storage incidental to transportation is within 172.600's scope.

An authorized government representative is investigating a hazardous-material incident involving a shipment subject to Subpart G. The immediate fire has ended. What happens to the required information-access duty?
Correct answer: The required information must remain immediately available to the investigator
Section 172.600(c)(2) covers authorized federal, state and local government representatives responding to an incident or conducting an investigation involving a hazardous material. Its application is not limited to an active fire.

A shipment subject to the emergency telephone-number rule remains in transportation during an overnight hold at a transfer terminal. When must its required number be monitored?

A required emergency number reaches a service that records a message but cannot provide knowledgeable help or immediate access to it. What makes that service inadequate?
Correct answer: A callback-only arrangement does not provide the required immediate capability
Section 172.604(a)(2) requires knowledgeable assistance or immediate access to someone with the necessary material and mitigation information. A service that only arranges a later callback does not meet that requirement.

A person registered with an outside emergency-information provider changes the material being offered but leaves the provider's product records unchanged. What must be ensured before the offer?
Correct answer: That the provider has received current information about the new material
Under 172.604(b)(2), the person registered with the ERI provider must ensure it has received current information about the material before it is offered. An unchanged telephone number or contract does not update the provider's material knowledge.

A covered shipment uses an outside ERI provider. Which shipping-paper entry can identify the person registered with that provider?
Correct answer: Registered name, or provider-assigned contract number or unique identifier
Section 172.604(b)(2) requires identification of the registered person by name or the ERI provider's contract number or other unique identifier, presented as required by that rule. Unrelated shipment references do not establish that relationship.

A trainee thinks the ERG is a complete cleanup plan for every stage of every hazardous-material incident. How should its intended role be described?
Correct answer: Guidance for first responders in a transportation incident's initial phase
PHMSA describes the ERG as a manual for first responders during the initial phase of a hazardous-materials transportation incident. That limited role does not make it a complete cleanup plan or confer specialized training.

After a suspected hazardous-material release, a bystander says the area is safe because the earlier odor is now faint. What should the driver recognize?
Correct answer: Odor strength does not establish that the area is safe
The manual warns against identifying a release by smell: harmful gases may have little odor or impair the sense of smell. Do not approach or use odor strength as proof of a safe atmosphere.

An unknown liquid has leaked from hazardous cargo. Someone proposes touching a small sample to identify it, although shipment information is already safely available. What is the appropriate response?
Correct answer: Avoid contact and leave scene assessment to appropriately trained responders
Do not touch leaking hazardous material to identify it. Small sample size and lack of visible fumes do not make direct contact safe. Use information already safely available and let appropriately trained responders assess the scene.

Hazardous cargo is burning, and the driver has neither specialized hazmat-fire training nor the protective equipment needed for it. What response fits those limitations?
Correct answer: Keep clear, warn others and summon trained emergency responders
The manual says hazardous-material fires require specialized training and protective equipment. In the stated situation, keep clear and call trained responders rather than attempt cargo firefighting. This is not a rule about every minor noncargo vehicle fire.

From a safe location, a driver reports a hazardous-material incident on a divided highway. Which information most directly helps responders find the scene and understand the known hazard?

Give the actual incident location and direction of travel, along with hazardous-material information already known and safely available. The planned destination is not the incident location. Do not return to a dangerous area to obtain more details.
