HAZWOPER Refresher Quiz – HAZMAT Safety & Procedures

Time, distance, and shielding are safety tactics commonly used to protect oneself from radiation exposure. These tactics involve minimizing the amount of time spent near a radiation source, increasing the distance between oneself and the source, and using shielding materials to block or reduce the amount of radiation that reaches the body. This suggests that the correct answer is radiation, as time, distance, and shielding are specific safety measures associated with this type of event.

The correct answer is "All of the above". Specialized containers include high pressure containers, cryogenic cargo tanks or cylinders, and casks for radioactive material. This means that all of these types of containers are considered specialized containers.

Non-bulk packages refer to smaller containers used for transportation and storage of goods. Carboys and cylinders are commonly used for liquids, while drums are used for both liquids and solids. Tankers and ships are used for bulk transportation of large quantities of goods. Therefore, drums are the correct answer as they are a type of non-bulk package commonly used for transportation and storage.

The signs and symptoms of exposure to hazardous materials can be either acute or chronic. Acute symptoms occur immediately or shortly after exposure and can include nausea, dizziness, and difficulty breathing. Chronic symptoms, on the other hand, develop over a longer period of time and can include cancer, organ damage, and respiratory problems. It is important to recognize and address both acute and chronic symptoms of exposure to ensure the safety and well-being of individuals.

The correct answer is "Rapid vaporization & expansion ratios". When dealing with cryogenic spills, it is important to consider the rapid vaporization and expansion ratios of the cryogenic substance. Cryogenic substances, such as liquid nitrogen or helium, have extremely low temperatures and can rapidly vaporize when exposed to the atmosphere. This can lead to a significant increase in volume and pressure, posing potential hazards. Therefore, understanding and managing the rapid vaporization and expansion ratios is crucial in safely handling cryogenic spills.

The correct answer is "Gouges" because damage to containers can include cracks, scores, dents, and gouges. Gouges refer to deep cuts or grooves on the surface of the container, which can compromise its structural integrity and potentially lead to leakage or other issues.

The manufacturer's recommendation is an important consideration when selecting proper chemical-protective clothing. Manufacturers have extensive knowledge about their products and can provide guidance on the specific chemicals and hazards that the clothing is designed to protect against. They can also provide information on the appropriate break through time, which is the time it takes for a chemical to penetrate the clothing. Therefore, following the manufacturer's recommendation ensures that the clothing will provide the necessary protection and minimize the risk of exposure to hazardous substances.

High pressure tube cars have 30 horizontal stainless steel cylinders. These cylinders are likely used to store compressed gases or liquids that require high pressure for transportation. Stainless steel is a suitable material for these cylinders as it is strong, corrosion-resistant, and can withstand high pressure. The use of stainless steel cylinders ensures the safety and integrity of the contents during transportation.

Cryogenic cargo tanks or cylinders are designed to store and transport materials that are liquefied at extremely low temperatures. The correct answer is -155 degrees F, as this temperature is within the range of cryogenic temperatures and is commonly used for the storage of liquefied gases such as nitrogen, oxygen, and argon.

Liquid pipelines are capable of carrying different products through a single line. This means that multiple types of liquids can be transported simultaneously in the same pipeline, which increases efficiency and reduces the need for separate pipelines for each product. This allows for more cost-effective transportation of various liquids, such as oil, gas, and chemicals, through a single pipeline network. Additionally, it offers flexibility in terms of product transportation and storage, as different products can be easily switched and transported through the same pipeline.
