HAZ MAT INCIDENT PRODUCT CONTROL FOR FIRST
RESPONDERS
2
Product Control

• Introduction
• The first responder at the operational level
  shall identify the defensive options for each
  response objective

3
Product Control

• Identification of defensive options
• Containment
• Confinement

4
Product Control

• Confinement Definition
• Those procedures taken to keep a material, once
  released, in a defined or local area.

5
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.)

6
Product Control

• Other General Control Methods
• Absorption
• Dikes, dams, diversion and retention
• Dilution
• Remote valve shut off
• Vapor dispersion
• Vapor suppression

7
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.

8
Product Control

• Control Methods
• Adsorption
• The material bonds to the outside of the
  adsorption medium.

9
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.)

13
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.

14
Product Control

• Control methods
• Dilution
• The application of water to water soluble
  hazardous materials to reduce the hazard.

15
Product Control

• Control methods
• Vapor dispersion
• Intentional movement of vapors to another area,
  usually by the use of master streams or hose
  lines.

16
Product Control

• Control methods
• Vapor suppression
• The reduction or elimination of vapors emanating
  from a spilled or released material.

17
Product Control

• Control Methods
• Criminal / Terrorist Acts
• Scene security
• Evidence preservation
• Victim / witness control

19
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.
