206.08 Tank Farm Flashcards
The tank farm serves as the primary distribution point for petroleum products in the Phoenix area. Most of these products arrive at the tank farm by ______ and are delivered to the tanks operated by various companies and agencies.
Pipe line
How are the products from this location distributed to service stations and other users?
Tank trucks
Additional underground pipelines
A number of different companies and agencies store and distribute product from adjoining facilities. A pipeline manifold provides for the distribution of products among the individual facilities. The central manifold is located where?
On 53rd Ave. in the Kender Morgan pipeline’s yard in the middle of the tank farm
The pipeline system delivers products to the tank farm at a high rate of flow. Flow may be up to _______. Who can shut down this flow?
6300 GPM
An on duty 24 hour operator
To shut down the pipeline, command should ________.
Direct dispatch to contact Kender Morgan pipelines and relay instructions
How long does it take to fully stop the incoming flow?
Several minutes
A complex system of piping interconnects all of the facilities in the tank farm complex, allowing products to be delivered or transferred. All of these lines connect to the manifold in the Kindle Morgan pipeline’s yard. What can the piping manifold be used for?
Subsurface foam injection into storage tanks
Many loading racks have automatic AFFF deluge sprinkler systems. The systems should be shut down as soon as fire control and/or a good foam blanket have been achieved. Why?
After the foam supply is exhausted it will discharge plain water that will damage the foam blanket
In the sprinkler system a FD connection may be provided to allow a _____ inch AFFF hoseline to be connected to supplement the flow through the deluge system.
2 1/2”
What are the three different categories of large storage tanks in use at the Tank Farm complex?
Floating roof
Cone roof
Cone/floating roof
What is the greatest concern with the tank?
Possibly an overflow spill
It is always important to control the _______ before attempting to control the tank surface fire, since a ______,would continue to reignite vapors coming from the tank.
Spill fire
Floating roof tanks may experience “rim” fires involving a seal area around the floater. These fires are generally controllable with what?
Small hand lines
Dry chemical extinguisher
When applying foam to a floating roof, care must be taken to ______ the floater.
Avoid sinking or tilting
Never apply plain water into a floating roof – it will cause the roof to sink
What are the preferred methods to control a full surface fire?
Subsurface foam injection
Topside fixed foam chambers
Hydro-foam monitor nozzles
When an entire tank top surface area is involved, hand line streams will not be able to penetrate the thermal column to reach the burning liquid surface. _______ are the only alternative to subsurface injection or fixed systems.
Large volume AFFF master streams
In the event of a working incident inside the tank from complex, an operation center will be established at ________.
Shell Oil USA terminal office
The first arriving unit shall provide what information to the initial report?
Specific location – name of shipper involved
Type of incident – leak, spill, fire or no fire
Extent of leak, spill, fire
Operation of any automatic systems
Tank number and location
Initial actions should be directed toward what tactical priorities?
Actions should proceed cautiously
High level of safety
Avoid committing personnel to dangerous situations
Major incidents at the tank farm complex will generally involve either a leak or a spill of petroleum product. This situation may or may not involve a fire. What are the tactical priorities?
Cover spill with foam blanket
Control potential source of ignition
Have a hazmat unit monitor blanket
Contain the spill or run-off
Identify and control the source of the spill or leak
Maintained foam blanket until products can be picked up
Keep all personnel out of spill area
A large spill can create an extremely large vapor problem and may flashback from ignition sources at significant distances. While covering the spill to suppress vapors, the _______ and _______ of vapor travel must be determined.
Direction
Extent
When attempting to control a large flammable liquid fire, what should the strategy be?
To wait until enough foam concentrate to control the fire is on the scene before beginning the attack
The truck and trailer at Station 34 stores how much foam?
4200 gallons
Fires that are controllable with the foam supply on hand should be ________.
Attacked without delay
