PRODUCT CONTROL
Product Control Introduction The first responder at the operational level shall identify the defensive options for each response objective
PRODUCT CONTROL Product Control l Identification of defensive options l Containment l Confinement
PRODUCT CONTROL Product Control l Confinement Definition: l “Those procedures taken to keep a material, once released, in a defined or local area.”
PRODUCT CONTROL Product Control l Containment Definition: The actions taken to keep a material in its container. (e.g., stop a release of the material or reduce the amount being released.)
PRODUCT CONTROL Product Control l Other General Control Methods l Absorption l Dikes, dams, diversion and retention l Dilution l Remote valve shut off l Vapor dispersion l Vapor suppression
PRODUCT CONTROL Product Control l Control methods l Absorption l The process by which one substance, such as a liquid, combines with another substance, such as a solid, by becoming part of that substance.
PRODUCT CONTROL Product Control l Control Methods l Adsorption l The material bonds to the outside of the adsorption medium.
PRODUCT CONTROL Product Control l Control methods l Diking/Damming: The use of a barrier to confine the movement of a material. l Diversion: The controlled movement of the liquid from one course of flow or area to a another locale. l Retention: The temporary confinement of a material in an area (e.g. pond, excavation, etc.). (Often used in conjunction with diversion.)

PRODUCT CONTROL Diversion
Retention
Product Control l Control methods l Remote valve shutoffs l Valves that can be used to shut off the flow of a chemical; the term remote is used to denote the valves that are away from the spill or release.
PRODUCT CONTROL Product Control l Control methods l Dilution l The application of water to water soluble hazardous materials to reduce the hazard.
PRODUCT CONTROL Product Control l Control methods l Vapor dispersion l Intentional movement of vapors to another area, usually by the use of master streams or hose lines.
PRODUCT CONTROL Product Control l Control methods l Vapor suppression l The reduction or elimination of vapors emanating from a spilled or released material.

PRODUCT CONTROL Product Control Practical Exercise You are dispatched for the investigation. Upon arrival, you find a tanker truck that is leaking an acid. It is leaking at a moderate rate. You must determine and perform the best method of product control.
