Question 1: Description of a Nonpressure Tank Facility (Floating Roof)
Answer:
A large capacity, above ground holding tank frequently stores flammable liquids (e.g. petroleum products). Designed so that the roof floats on product eliminating the hazard of vapor space. A fabric or rubber seal around the circumference of tank.
Question 2: Description of a Cryogenic Tank Facility
Answer:
Heavy insulated design with a vacuum in the space between inner and outer shell. Primarily found at heavy industrial facilities, hospitals, and gas processing facilities.
Question 3: Description of a Low Pressure Liquid Cargo Tank
Answer:
Insulated tanks look horseshoe shaped and noninsulated tanks appear round with ribs showing. Most common leaks are from the manway and the ends of the tank. Rollover protection surrounds the manways and the ends of the tank.
Question 4: Elaborate on the emergency shut-off valves for the pressure tank valves.
Answer:
Safety relief valves are usually set at 75% of tank test pressure.
Question 5: What do Intermodal tank containers transport?
Answer:
Bulk gases and liquids.
Question 6: What are the three basic types of Intermodals?
Answer:
- Pressure
- Non-Pressure
- Specialized (including cryogenic portable tanks, and tube modules)
Question 7: Description of a Nonpressure Tank Facility (Vapordome Roof Tank)
Answer:
Vertical storage tank with a giant bulge or dome on top. Attached to the underside of the dome is a flexible diaphragm that move in conjunction with the changes of pressure.
Question 8: What is the capacity of Intermodal tank?
Answer:
Range up to 5,500 gallons
Question 9: What is the working pressure of a Pressure Tank Car?
Answer:
Tank test pressures for these tank cars are from 100 psi to 600 psi.Question 10: What type of gases are not liquefied and are hauled in a tube module?
Answer:
Nobel Gases
Question 11: Description of a Radioactive Package Type B.
Answer:
Can weigh more than 100 tons. Packaging must be strong enough to withstand a 30' drop on it's weakest point. Puncture test drop from 40" onto a steel rod that is 6" in diameter and 8" high.
Question 12: What do Intermodals transport?
Answer:
Hazardous and non-hazardous materials (e.g. food grade commodities, liquid fertilizers, resins, anhydrous ammonia, liquefied petroleum gas (LPG), oxygen, helium, and nitrogen.Question 13: Where are the loading and unloading points on a non-pressure tank car?
Answer:
Fittings and valves visible on top of car.Often has bottom unloading valves.
Question 14: Where are the loading and unloading points on a pressure tank car?
Answer:
Typically out of site under the single protective housing on top of the tanks. Typically top loading with their fittings inside the protective housing mounted on the manway cover plate in the center of the tank.
Question 15: Description of a Nonpressure Tank Facility (Lifter Roof Tank)
Answer:
A lifter roof floats within a series of vertical guides that allow only a few feet of travel. The roof is either liquid or fabric-sealed and moves up and down with changes in vapor pressure.
Question 16: Description of a Cryogenic Liquid Cargo Tank
Answer:
Tank-within-a-tank design. Tank must have a suitable pressure guage, indicating the lading pressure, located on the front of the jacket so that the driver can read it in the rearview mirror.
Question 17: Description of a Pressure Tank Facility (Pressure)
Answer:
Painted white or some other reflective color. Commonly located at a site that dispenses petroleum products to the public. Elongated with rounded ends.
Question 18: Description of a Nonpressure Tank Facility (Ordinary Cone Roof)
Answer:
Cone shaped pointed roof. It is designed with a weak roof-to-shell seam, designed to break when/if the container becomes overpressurized. Vapor space is explosive if exposed to an ignition source. Hazard Class 3 and 8.
Question 19: What is the capacity of a Non-Pressure Tank Car?
Answer:
Capacities range from 4,000 gal to 45,000 gal.
Question 20: Description of a Nonpressure Tank Facility (Horizontal Tank)
Answer:
A horizontal tank supported on steel stilts that may be compromised quickly during fire.
Question 21: Give a description of a tank pressure tank car?
Answer:
Tank cars are cylindrical, non-compartmented tanks with rounded ends. Fittings and valves are enclosed in a dome. They may be insulated and/or thermally protected. Black paint usually indicates a jacketed tank car.
Question 22: What tank car is described as a tank-within-a-tank style?
Answer:
Cryogenic Liquid Tank Car
Question 23: Description of a Compressed Gas Tube Trailer
Answer:
Consist of a group of seamless steel cylinders, 9 to 48 inches in diameter. May have as few as two to more than twenty cylinders. All cylinder contain the same material. Each cylinder is independently piped and valved.
Question 24: Description of a Pressure Tank Facility (Noded Spheroid)
Answer:
The noded spheroid tank is held together by a series of internal ties and supports that reduce stress on the external shell. Bulging, ribbed sections (swelled looks).
