Son of a Breach
Breaks the container into two or more relatively large pieces (fragmentation) or tears.
What is Runaway Cracking?
This is a triangular-shaped pattern of a hazardous material release with a point source at the breach and a wide base downrange.
What is a Cone?
This describes the temperature at which a solid substance changes to a liquid state at normal atmospheric pressure.
What is Melting?
This is the process of injecting an odorant into a combustible gas so that it is detectible by smell.
What is Odorization?
This defines operations in which responders seek to confine the emergency to a given area without directly contacting the hazardous material involved.
What is Defensive Mode?
This occurs when foreign objects penetrate through a container.
What is Puncture?
This is a ball-shaped pattern of the airborne hazardous material that collectively rises above the ground or water.
What is a Cloud?
This is a Surface-following pattern of liquid hazardous material that is affected by gravity and topographical contours.
What is a Stream?
This defines two or more liquids' capability to mix together.
What is Miscibility?
What is a Site Safety Plan (SSP)?
Mechanical or thermal stressors may cause these, such as when a seam on a bag of fertilizer rips.
What is a Split or Tear?
This is an irregularly shaped pattern of an airborne hazardous material where wind and/or topography influence the downrange course from the point of release.
What is a Plume?
This is a three-dimensional (including depth), slow-flowing liquid dispersion. Liquids assume the shape of their container and collect in low areas.
This defines a material that is incapable of being mixed or blended with another substance.
What is Immiscible?
This is the overall plan for the incident attack and control established by the Incident Commander (IC).
What is Strategy?
These may fail, open, or break off when subjected to stress, leading to total failure of a container.
What are Attachments (Closures)?
This is a semicircular or dome-shaped pattern of airborne hazardous material that is still partially in contact with the ground or water.
What is Hemispheric?
These occur when water is present or enters a tank containing hot viscous oil and the sudden conversion of water to steam causes a portion of the tank contents to overflow.
What is Froth-overs?
This is the degree of which a solid, liquid, or gas dissolves in a solvent (usually water).
What is Solubility?
These are the methods of employing equipment and personnel on an incident to accomplish specific tactical objectives, in order to achieve established strategic goals.
What are Tactics?
This occurs in containers that are made of a brittle material (or that have been made more brittle from some form of stress), causing the container to sustain a general loss of integrity.
What is Disintegration?
This is dispersion of material as defined in the General Emergency Behavior Model (GEBMO); an event such as this occurs when matter and/or energy disperses and forms a danger zone.
What is Engulfment?
This is a situation that occurs when burning oil that is stored in a tank is forced over the edge of the tank by water that is heated to the boiling point and have accumulated under the surface of the oil.
What is Slop-overs?
This is a material in which the positive and negative charges are permanently separated, resulting in their ability to ionize in solution and create electrical conductivity. This also defines flammable liquids with an attraction for water.
What is a Polar Solvent?
This defines operations in which responders take aggressive, direct action on the material, container, or process equipment involved in an incident.
What is the Offensive Mode?
