one engine.
If a spill ignites what resources should be requested?
Foam Task Force
What’s a Foam Task Force?
2 AR foam units, one pump and roll unit, 2 engines, 1 BC, 1 Hazmat assest
What is defined as a large spill?
55 gallons or more, multiple spills from multiple containers.
What is the dispatched algorithm for Large Spill?
4 Engines, 2 specialty with one of those a truck, 2 EMS units, 1 BC, 1 safety/ command aide, 1 EMS supervisor, 1 FOAM Task Force, HAZMAT response
What are 4 tactical approaches to tanker truck incidents?
- Assemble resources and extinguish the fire with Class B foam
- Extinguish fire with water fog so long as run off is no issue
- Protect adjacent exposures and let fuel burn out
- Un-ignited leaks and spills diked and liquid covered with foam
During a tanker fire what unit can act as the attack unit?
the pump and roll unit
First arriving unit main priority is?
Scene Safety
How should you position during a flammable liquid spill?
Uphill and up wind out of product or spill
If no release is detected on a tanker truck leak what could you look for to indicate a possible leak?
people who are ill and or unconscious
What are the resources required for a rail car incident?
Same as a large spill
How is the majority of Ethanol fuel (E-95) transported?
By rail
How far are flaggers positioned away from the incident of railroad emergencies?
2 miles in each direction
What should the IC consider for an off- airport aircraft incidents?
More pump and roll foam units
What are the 2 primary factors for transformer fires?
Load and age
If PCBs are suspected transformer fire what PPE should be used?
Turnout and SCBA
In the event of a pipeline rupture what must established early in the incident?
Control of the flow from the pipe
What are the 6 overall goals of a bulk petroleum facilities fire?
- Rescue
- Public protection actions
- Spill control/confinement
4.Leak control/ confinement - Fire control
- Recovery
Risk assessment at a loading rack fuel spill is devloped how?
By proper recon, info gathering from pre-incident plans, employees and scene observation
What will have a direct impact on the size and scope of any exposure issue?
Terrain, Wind direction, and ambient temperature
When dealing with a loading rack spill the most efficent and effective exposure protection is to do what?
Suppress vapors by applying a finished foam blanket
When dealing with a loading rack spill the most efficient and effective exposure protection is to do what?
Suppress vapors by applying a finished foam blanket
How should you tactically approach a tanker fire?
Never approach from the end of the vehicle.
Attempt to bank the finished foam off the vehicle tank
Extinguish all ground fires before concentrating on any fire with the tanker
In case of a storage tank fire what must be addressed prior to the problem with the tank?
The dike area must be evaluated
What ancillary equipment and components represent serious hazards during a fire within the dike area of a bulk petro facility
Piping in and around the dike area. Pipe supports. Pumps. Valves, connections and couplings.
Any tank greater than __ feet in diameter is required to have a weak roof to shell seam
50
What type of fire is most among cone roof tanks
Vent
What is a common fire associated with open floating roof petro storage tanks?
Seal fire
In a vent fire involving low pressure horizontal or vertical tank the most important tactical issue is?
Keeping the upper portion of the exposed tank shell cool with adequate water flow until the fire can be extinguished
