Storage Containers - Fixed Facility Flashcards
What are the THREE primary types of fixed facility storage tanks, AND where are they installed?
- Non-pressure; installed above ground.
- Pressure; installed below ground.
- Cryogenic; installed inside of buildings.
This fixed facility storage container:
- operates at atmospheric pressure, 0 to 0.5 psig (non pressure)
- stores hazard classes 3, 4, 5, and 8
- ex. combustible and flammable liquids, corrosives, oxidizers, and solvents.
- tank with a PERMANENTLY ATTACHED, sloped roof with weak seams where the roof meets the sides.
Cone Roof Tank
This fixed facility storage container:
- has a working pressure of 0 to 0.5 psig (non pressure)
- hazard class 3
- ex. flammable and combustible liquids
- capacity ranges from 50,000 to over 1,000,000 gallons.
Floating Roof w/Geodesic Dome
note: the floating roof is inside the structure while the dome sits on the top.
This fixed facility storage container:
- has a working pressure of 0 to 0.5 psig (non-pressure)
- hazard classes 3 and 8
- flammable, combustible, and corrosive liquids
- ladder on roof
- the roof actually floats on liquid surface
- capacity range from 50,000 gallons to over 1,000,000 gallons
Floating Roof Tank (Open Floating Roof Tank)
This fixed facility storage container:
- has a working pressure of 0 to 0.5 psig
- hazard class 3
- ex. flammable and combustible liquids
- large vents found at the top of the tank shell
- also referred to as an internal floating roof
Lifter Roof Tank (Covered Floating Roof Tank)
This fixed facility storage container:
- has a working pressure of 0 to 0.5 psig
- range in size up to a maximum of about 8,500,000 gallons
- hazard classes 3, 5, and 9
- flammable and combustible liquids
- some non-hazardous materials such as molasses and fertilizer blends may be stored in this style of tank.
- vertical storage tank with a giant bulge or dome on its top
- attached to the underside of the dome is a flexible diaphragm that moves in conjunction with changes in vapor pressure.
Vapor Dome Roof Tank
This fixed facility storage container:
- has a working pressure of 0 to 0.5 psig
- capacity ranges from 300 to 20,000 gallons
- hazard classes 3, 5, 6, 8, and 9
- commonly used for bulk storage in conjunction with FUEL-DISPENSING operations
- can be used to store solvents, oxidizers, poison liquids, and corrosives
Horizontal Tank (Atmospheric)
This fixed facility storage container:
- capacity will vary based on construction design.
- has a working pressure of 0.5 to 15 psig
- hazard classes 2 and 3
- ex. LPG, methane, propane and other light gases. It may also contain certain flammable liquids such as gasoline and crude oil.
Noded Spheroid
This fixed facility storage container:
- has a capacity of 3,000,000 gallons or more
- working pressure of 0.5 to 15psig
- hazard classes 2 and 3
- ex. LPG, methane, propane and other light gases. It may also contain certain flammable liquids such as gasoline and crude oil.
Spheroid
This fixed facility storage container:
- has a capacity of 600,000 gallons of product
- working pressure of 0.5 to 15 psig
- hazard class 2
- flammable and non-flammable liquefied gases
Sphere
This fixed facility storage container:
- has a working pressure of 15psi and above
- capacity of 500 to 40,000 gallons
- hazard class 2
- flammable and non-flammable liquefied gases
Pressure Vessel
This fixed facility storage container:
- varying pressures, but some can be high (over 300 psi)
- capacity of 500 to 20,000 gallons
- hazard class 2.2
- liquefied argon, ethylene, helium, nitrogen, and oxygen
- heavily insulated with a vacuum in the space between the outer and inner shells. These tanks are designed to carry refrigerated commodities.
