Ch. 10: Implementing Response Objectives Flashcards
What are the specific objectives the IC uses to achieve strategic goals?
tactics
In order to be effective, what must need to be concise, easy to communicate, and achievable in a given timeframe with the resources available?
objectives
What mode of operations commits the IC’s resources to aggressive leak, spill, and fire control objectives?
offensive
What mode of operations commits resources to less aggressive objectives?
defensive
What mode means taking no action other than isolating the area?
nonintervention
What mode does hazmat operations begin in?
defensive mode
What are the most difficult decisions responders must make?
Those related to life safety
What is an important step in getting the IC’s strategic game plan implemented?
Getting a buy-in from the risk takers.
What has a stated objective that can be achieved using specific procedures and tasks within a reasonable period of time?
a well-defined tactic
What is about whether to use one tactic over another?
tactical decision making
What are the actions taken to confine a product release to a limited area?
spill-control strategies and confinement tactics
What is the physical process of absorbing or “picking up” a liquid hazardous material to prevent enlargement of the contaminated area?
absorption
What is the chemical process in which a sorbate interacts with a solid sorbent surface?
adsorption
What is a physical method of confinement?
covering
What is a physical method of confinement by which barriers are constructed to prevent or reduce the quantity of liquid flowing into the environment?
damming
What is a physical method of confinement by which barriers are constructed on ground used to control the movement of liquids, sludge, solids, or other materials?
diking
When are dikes most effective?
When they can be built quickly.
What is a chemical method by which a water-soluble solution, usually a corrosive, is diluted by adding large volumes of water to the spill?
dilution
What is the major disadvantage to dilution?
It is not well understood by emergency response personnel.
What is a physical method of confinement by which barriers are constructed on ground or placed in a waterway to intentionally control the movement of a hazardous material into an area where it will pose less harm to the community and the environment?
diversion
What is a chemical method by which certain chemical and biological agents are used to disperse or break up the material involved in liquid spills on water?
dispersion
What is a physical method by which water spray or fans are used to disperse or move vapors away from the surface areas of the product?
vapor dispersion
What is a physical method to reduce or eliminate the vapors emanating from a spilled or released material?
vapor suppression
What is a chemical method by which a hazmat is neutralized by applying a second material to the original spill that will chemically react with it to form a less harmful substance?
neutralization
What should be neutralized by applying the neutralizing material from the outermost edge inward, thereby protecting responders?
corrosive spills
What is a physical method of confinement by which a leaking drum, container or cylinder is placed inside a larger undamaged and compatible overpack container?
overpacking
What containment method uses chemically compatible patches and plugs to reduce or temporarily stop the flow of materials from small container holes, rips, tears, or gashes?
patching (plugging)
What method of containment is by which the internal pressure of a closed container is reduced?
pressure isolation and reduction
What can be done by simply lowering the pressure or completely isolating or shutting down the compressor or pumping system?
The magnitude of the leak can be significantly reduced.
What is the controlled release of a material to reduce and control the pressure, and decrease the probability of a violent container rupture?
venting
What is usually associated with venting and involves the use of physical or chemical filters or control devices to “scrub” contaminants, particulates, or gases during normal or emergency process operations?
scrubbing
What is the controlled burning of a liquid or gas material to reduce or control pressure inside the tank, dispose of residual vapors, and/or to dispose of a product when transfer operations may be impractical?
flaring
What is used to gain access to bulk liquid or gas tanks, pipelines, or containers for the purpose of product removal?
hot tapping
What is a chemical method of containment whereby a liquid substance is chemically treated so that a solid material results?
solidification
What is a physical method of containment by which a hazardous material is placed in a chemically compatible container by simply vacuuming it up?
vacuuming
Which hazmat classes have historically produced the most injuries and fatalities to emergency responders and are encountered in virtually every plant and community?
Flammable liquids, gases, and reactive chemicals.
What are the most common hazard class encountered by emergency responders?
flammable liquids
What is the workhouse of flammable liquid firefighting?
Class B foam
What should be considered to be done when dealing with three-dimensional fires?
Be sure the fuel source can be shut off when the fire is extinguished.
What is a flammable and odorless gas and is methane in its liquid state?
Liquefied natural gas (LNG)
