Erg pipeline transport
In North America, hazardous materials are commonly transported through millions of miles of
Pipelines and related structures
First responders should be aware of the____ in there jurisdiction, the___they transport, and the____ responsible for those pipelines.
Pipelines, products, operators
____ relationships can be beneficial in the safe and effective management of pipeline emergencies
Proactive
Pipeline structures (above ground) natural gas distribution pipelines:
Regulator Stations, customer meters and regulators, valve box covers
Markers for pipelines transporting materials containing dangerous levels of HYDROGEN SULFIDE may have markers that say;"____ "or "_____"
Sour or poison
Natural gas gathering/well production pipelines collect "___" Natural gas from wellheads and transport the product to gas-processing and/or gas-treating plants. These gathering pipelines carry natural gas mixed with some quantity of gas liquids, water, and in some areas, contaminants such as toxic hydrogen sulfide. Natural gas in these pipelines is not odorized with mercaptan,However, natural gas that contains___ will have a distinct start "rotten egg" odor
"Raw" hydrogen sulfide
Natural gas transmission pipelines: Large diameter, steel pipe lines transport flammable natural gas at very high pressures ranging from___ to ___ psi.
200 to 1500 psi
Gathering/production pipelines are often not marked with_____-_____ signs
Above - ground signs
Natural gas distribution pipelines are not marked with
Above - ground signs
Pipeline structures (above ground) natural gas transmission pipelines;
Compressor stations, valves, metering stations
Pipeline structures (above ground) naturalGas gathering/well production pipelines;
Compressor stations, valves, metering stations, well head, piping, manifolds
Liquid petroleum pipeline's
Crude oil, refined petroleum products, and hazardous liquid often or transported by pipeline and include gasoline, jet fuel's, diesel fuel, home heating oil's, carbon dioxide, anhydrous ammonia, and other hazardous liquids. Many liquid petroleum pipelines transport different types of liquid petroleum in the same pipeline. To do so, the pipeline operator sends different products in "batches". For example an operator could send gas for several hours, and then switch to jet fuels, before switching to diesel fuel
Natural gas transmission pipelines
Large diameter, steel pipe lines transport flammable natural gas at very high pressures ranging from 200 to 1500 psi.
Natural gas in transmission pipelines Is odorless - generally not odorized with___;However, natural gas containing____will have a distinct "rotten -egg" odor
Mercaptan, hydrogen sulfide
Markers and Warning signs are located at frequent intervals along___and___ transmission pipeline rights-of-way, and are located at PROMINENT points such as where pipelines intersect?
Natural Gas and Liquid Streets, highways, railways, and waterways
Natural gas distribution pipelines
Natural gas is delivered directly to customers via distribution pipelines. These pipelines are typically smaller diameter, lower pressure pipe lines constructed of steel, plastic, or cast iron.
Products transported through pipelines in related structures include
Natural gas, natural gas liquids, crude oil, gasoline, diesel fuel, anhydrous ammonia,Carbon dioxide, jet fuel, and other commodities
Pipeline structures (above ground) Petroleum and hazardous liquid pipelines
Storage tanks, valves, pop stations, loading racks
Although most pipelines are buried, often there are above-ground ___ and ____ indicating the____ of pipelines
Structures and markers, Presence
Pipelines Markers only indicate what?
The presence of a pipeline - they do not indicate the exact location of the pipeline Pipeline locations within a right-of-way may vary along its length and there may be multiple pipelines located in the same right-of-way
Of the three types of pipelines typically buried underground-transmission, gathering, and distribution only_____________pipelines are marked with the following above ground markers used to indicate the route
Transmission
Pipeline markers are used for what
Worn the transmission pipeline is located in the area, identify the product transported in the line, and provide the name and telephone number of the pipeline operator to call.
Natural gas is delivered directly to customers via____ pipelines.
distribution
Other Hazardous Liquid Pipelines- Some liquid pipelines transport highly volatile liquid that rapidly change from a___to___when released from a pressurized pipe line Examples of these types of liquids include: ____,___,___and others
liquid to gaseous carbon dioxide anhydrous ammonia propane And others
Natural gas in distribution pipelines is odorized with____ "rotten egg smell"
metcaptan
Indications of pipeline leaks and ruptures: Pipeline releases can range from relatively ___leaks to____ ruptures. It is important to remember that gases and liquids behave____ once they are released from the pipeline.
minor, catastrophic Differently
Natural gas is delivered directly to customers via distribution pipelines. These pipelines are typically smaller-diameter,lower-pressure pipe lines constructed of?
steel, plastic, or cast iron.
Generally, the following could be an indication of a pipeline leak or rupture:
•hissing,Roaring, or explosive sound •Flames up hearing from the ground or water •Vapor cloud/fog/mist •Dirt/debris/water blowing out of the ground •Liquid bubbling up from the ground or bubbling in water •Distinctive, unusually strong odor of rotten eggs, Skunk, or petroleum •Discolored/dead vegetation or discolored snow above a pipeline right of way •Oil slick or Sheen on flowing/standing water
