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 Identification of defensive options Containment Confinement PRODUCT CONTROL Product Control Confinement Definition: “Those procedures taken to keep a material, once released, in a defined or local area.” PRODUCT CONTROL Product Control 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 Other General Control Methods Absorption Dikes, dams, diversion and retention Dilution Remote valve shut off Vapor dispersion Vapor suppression PRODUCT CONTROL Product Control Control methods Absorption 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 Control Methods Adsorption The material bonds to the outside of the adsorption medium. PRODUCT CONTROL Product Control Control methods Diking/Damming: The use of a barrier to confine the movement of a material. Diversion: The controlled movement of the liquid from one course of flow or area to a another locale. Retention: The temporary confinement of a material in an area (e.g. pond, excavation, etc.). (Often used in conjunction with diversion.) PRODUCT CONTROL Diking / Damming PRODUCT CONTROL Diversion PRODUCT CONTROL Retention PRODUCT CONTROL Product Control Control methods Remote valve shutoffs 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 Control methods Dilution The application of water to water soluble hazardous materials to reduce the hazard. PRODUCT CONTROL Product Control Control methods Vapor dispersion Intentional movement of vapors to another area, usually by the use of master streams or hose lines. PRODUCT CONTROL Product Control Control methods Vapor suppression The reduction or elimination of vapors emanating from a spilled or released material.

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. PRODUCT CONTROL
