Flammable Liquid Emergency Incidents Flashcards
The three operating modes for incidents involving flammable liquids are
- offensive mode
- defensive mode
- non-intervention
This operating mode is a commitment of resources to aggressive leak, spill, and fire control objectives
Offensive Attack Mode
This operating mode uses available resources to achieve less aggressive objectives such as limiting the overall size or spread of the problem
Defensive Attack Mode
This operating mode means taking no immediate action other than isolating the area until the risk of intervention is reduced to an acceptable level so that operations may transition to offensive or defensive strategies
Non-intervention mode
The first due engine company shall do what on a flammable liquid emergency?
Perform initial size-up & identify any obvious life hazards
Recon teams should be equipped with what?
- appropriate PPE
- detection equipment
- binoculars
- thermal imager
The rule of thumb when developing the water supply plan is that the supply should be able to flow at least ______ GPM of finished product per unit flowing product.
100
The water supply group supervisor will be given to
the 3rd due engine officer or 2nd due BC
The two main types of product that may be dealt with are
- Hydrocarbons
- Polar Solvents
Are organic compounds containing only hydrogen and carbon and are found primarily in petroleum products and coal
Hydrocarbons
Typical hydrocarbon fuels include
gasoline & diesel fuel
Are products of distillation that are water soluble
Polar solvents
Examples of polar solvents include
alcohols (such as ethanol), ketones, lacquers
Flammable liquids have a flash point below ______ degrees Fahrenheit and having a vapor pressure not exceeding _____ PSI absolute
100 ; 40
Combustible liquids have a flash point above ______ degrees Fahrenheit and below _______ degrees Fahrenheit
100 ; 200
To extinguish an ethanol fire it is recommended to use what type of foam
Alcohol-Resistant (AR) foam
The majority of the fuel ethanol is transported from the production facilities to the storage depots by what mode of transportation
Rail
A small spill is a spill occuring from a container or package of ____ gallons or less
55
A large spill is a spill exceeding ____ gallons or multiple spills from multiple small packages or containers
55
The resources required for the management of a large spill with or without fire include
- 4 engines
- 2 specialty units (1 must be aerial)
- 2 EMS units
- 1 BC
- 1 command aide
- 1 EMS Sup
- 1 Foam Task Force
- Hazmat material response
Before or during response units should obtain initial information concerning
Weather conditions
The most prevalent style of transport of the blended fuels encountered will be
MC-306
DOT-406
The MC-306/DOT-406 are non-pressurized and have a capacity up to _______ gallons
9,000
How large should placards be and how many sides of the vehicle should carry them
10.75” and all 4 sides
Flammable liquids will be found most often in general service rail cars of what PSI
less than 100 PSI
General service rail cars will carry approximately _________ gallons of product
30,000
The three benchmarks that define the nature and current scope of a flammable or combustible liquid incident are
- Life Safety
- Incident stabilization
- Property conservation
The overall strategic goals of any incident at a bulk petroleum facility are
- Rescue
- Public protection action
- Spill control
- Leak control
- Fire control
- Recovery
Small foam nozzles that are handheld flow what GPM
30-250
Storage tank that has fixed roofs that are either cone, dome or relatively flat by design
Cone/fixed roof tanks
One of the more common types of fires involving cone roof tanks is
Vent fires
A common problem associated with open floating roof petroleum storage tanks is
Seal fire
This method of foam application directs the foam stream on the ground near the front edge of the spill so finished foam rolls across the surface of the fuel
Roll-on method
This method directs the foam stream off an object that is elevated above the spill and allows finished foam to run down onto the surface of the fuel
Bank-down method
This method directs the foam stream into the air above the spill and allows finished foam to float gently down onto the surface of the fuel
Rain-down method
