    A combustible liquid has a flash point above 200 deg (F).

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A combustible liquid is one with a flash point at or above 100 degrees Fahrenheit (37.8 degrees Celsius) but below 200 degrees Fahrenheit (93.3 degrees Celsius). Contrarily, a flash point above 200 degrees Fahrenheit categorizes the liquid as non-combustible. This distinction is crucial for regulatory purposes, ensuring appropriate handling and storage practices based on the liquid's flammability characteristics. Non-combustible liquids pose a lower fire hazard compared to combustible liquids with lower flash points.

    • Cryogenic liquid tank car

    • Pressure tank car

    • High-pressure cargo tank

    • Non-pressure liquid cargo tank

    Correct Answer
    A. Pressure tank car
    Explanation
    A pressure tank car is the correct answer because it is designed to hold gases under pressure. The given information states that the tank has a pressure range of 100-600 psi, which aligns with the purpose of a pressure tank car. It is also mentioned that the tank has top loading/unloading, pressure relief, and gauging features, which are common characteristics of a pressure tank car. The other options, such as cryogenic liquid tank car and non-pressure liquid cargo tank, do not match the given specifications of capacity and pressure.

    What is the term for shipping papers used in rail transportation?

    • Waybill

    • Bill of lading

    • Manifest

    • Consist

    Correct Answer
    A. Waybill
    Explanation
    In rail transport, the waybill acts as a receipt and a guide for the shipment. It contains detailed information about the goods being transported, their origin, destination, routing, and any special instructions. It's essential for tracking and managing the shipment throughout its journey. While a bill of lading is also a shipping document, it's more commonly used in maritime shipping. A manifest is a summary of the cargo, and a consist specifically refers to the makeup of a train in terms of the cars and their order.

    A container can release its contents (breach) by all of the following except

    • Detonation (explosion of contents)

    • Violent rupture (NOT an explosion)

    • Oxidizing of hazardous materials

    • Rapid relief (safety valve operation/failure)

    • Spill or Leak

    Correct Answer
    A. Oxidizing of hazardous materials
    Explanation
    Oxidizing of hazardous materials does not directly result in the release of contents from a container. Oxidizing refers to a chemical reaction in which a substance gains oxygen or loses electrons. While this process can potentially lead to a release of contents in certain scenarios, it is not a direct cause of breaching a container.

    A bill of lading is used for Highway transport and rail vehicles.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A bill of lading is not used for Highway transport and rail vehicles. It is a legal document that is typically used in maritime shipping to acknowledge the receipt of goods and to provide evidence of the contract of carriage. For Highway transport and rail vehicles, different documents such as a waybill or a consignment note are used instead.

    Cough, tightness in the chest, and shortness of breath are symptoms of

    • Asphyxiant agent

    • Pulmonary agent

    • Blood agent

    • Mutagen

    Correct Answer
    A. Pulmonary agent
    Explanation
    Cough, tightness in the chest, and shortness of breath are symptoms commonly associated with pulmonary agents. Pulmonary agents are substances that primarily affect the respiratory system, causing irritation and inflammation in the lungs. These symptoms are indicative of the respiratory distress caused by the exposure to pulmonary agents. Asphyxiant agents, on the other hand, cause suffocation by displacing oxygen in the air, blood agents affect the body by interfering with the blood's ability to carry oxygen, and mutagens are substances that can cause genetic mutations.
