Exercise OutlineBlock I: Scenario and Response QuestionsPipeline ScenarioAt 6:00 a.m. today the ABC Pipeline Operator arrives at the facility and begins inspecting an above-ground valve site. Heimmediately notices four metal cylinders with closed ends; red, black and white wires around the cylinders; a pressureswitch, 9-volt battery, a device resembling a cell phone and duct tape holding the metal cylinders to the gate valve.Based on scenario information provided, participate in a discussion concerning the key issues raised in Block I. Identify anyadditional requirements, critical issues, decisions, or questions that should be addressed at this time. Be prepared to shareyour table discussion with the entire group.Discussion QuestionsFollowing the initial 911 call and subsequent mobilization of the response resources assigned by dispatch: Pipeline personnel: What are the Pipeline Company’s initial actions in response to this call (Emergency Response Plan)? What agencies and/or departments should be notified and who makes that call? Once on the scene, what are the actions of the local Pipeline Operator?13MLGPA20

Exercise OutlineBlock II: On-Scene Response QuestionsBriefing UpdateEmergency responders have arrived on scene. An Incident Command Post (ICP) has been set up nearby. While gatheredat the ICP, on scene personnel monitor bomb technicians. The technician utilizes a robot to monitor the device, with theassistance of support personnel.Without warning, an audible ringing sound is heard coming from the IED, followed by the device detonating a few secondslater. While the product isn’t on fire, it is releasing from the facility now.Based on the scenario information provided, participate in a discussion concerning the key issues raised in Block II. Identifyany additional requirements, critical issues, decisions, or questions that should be addressed at this time.Discussion QuestionsGiven our shared priorities of preserving life, property, and the environment: How will the emergency services, pipeline operators, and excavators stay in communication? What factors would help determine the appropriate protective action(s) for this incident? Shelter-in-place Evacuation Pipeline personnel: Given the detonation, what procedures will your control center (SCADA system) and field personnelfollow? What sources can you use to find information about product hazards and characteristics?14MLGPA20

Exercise OutlineBlock III: Expansion or DemobilizationBriefing UpdateThe local pipeline operator has advised that the process of closing remote valves and “drawing down” the product in theaffected area has begun.Local first responders and elected officials (city and county) have arrived on scene and are requesting to speak withcommand staff.A television station has arrived on-scene and is also requesting to speak with command staff. They are broadcasting livefrom the scene.Based on scenario information provided, participate in a discussion concerning the key issues raised in Block III. Identifyany additional requirements, critical issues, decisions, or questions that should be addressed at this time.Discussion QuestionsGiven the situation as it currently stands: Pipeline personnel: How long will it take to stop the flow of product? Who will coordinate the actions of the excavators on scene? Is there the potential for federal and state agencies to be involved in this incident? How will emergency responders and the pipeline company coordinate to inform the media?15MLGPA20

Hazardous Liquids Material Data SheetPOTENTIAL HAZARDSFIRE OR EXPLOSION HIGHLY FLAMMABLE: Will be easilyignited by heat, sparks or flames. Vapors may form explosive mixtures withair. Vapors may travel to source of ignition andflash back. Most vapors are heavier than air. They willspread along ground and collect in lowor confined areas (sewers, basements,tanks). Vapor explosion hazard indoors, outdoorsor in sewers. Those substances designated with a “P”may polymerize explosively when heatedor involved in a fire. Runoff to sewer may create fire orexplosion hazard. Containers may explode when heated. Many liquids are lighter than water. Substance may be transported hot. If molten aluminum is involved, refer toGUIDE 169.HEALTH Inhalation or contact with material mayirritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution watermay cause pollution.FIRECAUTION: All these products have a verylow flash point: Use of water spray whenfighting fire may be inefficient.CAUTION: For mixtures containingalcohol or polar solvent, alcohol-resistantfoam may be more effective.Small Fire Dry chemical, CO2, water spray or regularfoam.Large Fire Water spray, fog or regular foam. Use water spray or fog; do not use straightstreams. Move containers from fire area if you cando it without risk.PUBLIC SAFETY CALL Emergency Response TelephoneNumber on Shipping Paper first. IfShipping Paper not available appropriatetelephone numbers can be found in theEmergency Response Guidebook. As an immediate precautionary measure,isolate spill or leak area for at least 50meters (150 feet) in all directions. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate closed spaces before entering.PROTECTIVE CLOTHING Wear positive pressure self-containedbreathing apparatus (SCBA). Structural firefighters’ protective clothingwill only provide limited protection.EVACUATIONLarge Spill Consider initial downwind evacuation for atleast 300 meters (1000 feet).Fire If tank, rail car or tank truck is involvedin a fire, ISOLATE for 800 meters (1/2mile) in all directions; also, consider initialevacuation for 800 meters (1/2 mile) in alldirections.EMERGENCY RESPONSEPRODUCT: Crude OilDOT GUIDEBOOK ID #:GUIDE #:1267128PRODUCT: Diesel FuelDOT GUIDEBOOK ID #:GUIDE #:1202128PRODUCT: Jet FuelDOT GUIDEBOOK ID #:GUIDE #:1863128PRODUCT: GasolineDOT GUIDEBOOK ID #:GUIDE #:1203128Refer to the Emergency ResponseGuidebook for additional products notlisted.Fire involving Tanks or Car/Trailer Loads Fight fire from maximum distance oruse unmanned hose holders or monitornozzles. Cool containers with flooding quantities ofwater until well after fire is out. Withdraw immediately in case of risingsound from venting safety devices ordiscoloration of tank. ALWAYS stay away from tanks engulfed infire. For massive fire, use unmanned hoseholders or monitor nozzles; if this isimpossible, withdraw from area and let fireburn.FIRST AID Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is notbreathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothingand shoes. In case of contact with substance,immediately flush skin or eyes with runningwater for at least 20 minutes. Wash skin with soap and water. In case of burns, immediately cool affectedskin for as long as possible with cold water.Do not remove clothing if adhering to skin. Keep victim warm and quiet. Ensure that medical personnel are awareof the material(s) involved and takeprecautions to protect themselves.SPILL OR LEAK ELIMINATE all ignition sources (nosmoking, flares, sparks or flames inimmediate area). All equipment used when handling theproduct must be grounded. Do not touch or walk through spilledmaterial. Stop leak if you can do it without risk. Prevent entry into waterways, sewers,basements or confined areas. A vapor suppressing foam may be used toreduce vapors. Absorb or cover with dry earth, sandor other non-combustible material andtransfer to containers. Use clean non-sparking tools to collectabsorbed material.16MLGPA20

Highly Volatile Liquids Material Data SheetPOTENTIAL HAZARDSFIRE OR EXPLOSION EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks orflames. Will form explosive mixtures with air. Vapors from liquefied gas are initiallyheavier than air and spread along ground.CAUTION: Hydrogen (UN1049),Deuterium (UN1957), Hydrogen,refrigerated liquid (UN1966) andMethane (UN1971) are lighter than airand will rise. Hydrogen and Deuteriumfires are difficult to detect since theyburn with an invisible flame. Use analternate method of detection (thermalcamera, broom handle, etc.) Vapors may travel to source of ignition andflash back. Cylinders exposed to fire may vent andrelease flammable gas through pressurerelief devices. Containers may explode when heated. Ruptured cylinders may rocket.HEALTH Vapors may cause dizziness orasphyxiation without warning. Some may be irritating if inhaled at highconcentrations. Contact with gas or liquefied gas maycause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxicgases.FIRE DO NOT EXTINGUISH A LEAKING GASFIRE UNLESS LEAK CAN BE STOPPED.CAUTION: Hydrogen (UN1049),Deuterium (UN1957) and Hydrogen,refrigerated liquid (UN1966) burn withan invisible flame.
