DoD HAZMAT Tech Part II (Control Measures - E)

Process by which materials hold liquids. Absorption.
Chemical method of decontamination involving the interaction of a hazardous liquid and a solid sorbent surface which stays rigid, with no volume increase. Adsorption.
Examples of Adsorption. Activated Charcoal. Silica. Aluminum Gel. Fuller’s Earth.
Applying a cover of gas over the surface of a hazardous material. Blanketing.
Physical Method of confinement, typically a temporary measure. Covering.
Physical method of confinement by which barriers are constructed to prevent or reduce the quantity of liquid flowing into the environment. Damming.
This type of dam is used to trap floating lighter-than water materials behind the dam. Underflow dam.
Spill control tactic used to trap sinking heavier-than-water materials behind the dam. Overflow dam.
Physical method of confinement by which barriers are constructed on ground used to control the movement of liquids, sludges, solids, or other materials. Diking.
Reducing the concentration of a contaminant. Dilution.
Chemical method of confinement by which certain chemical or biological agents are used to disperse or break up the material involved in liquid spills or water. Dispersion.
Physical method of confinement by which barriers are contructed on ground or placed in a waterway to intentionally control the movement of a hazardous material. Diversion.
Activities involved in controlling and extinguishing fires. Fire suppression.
Altering a contaminant chemically so that the resulting chemical is harmless. Neutralization
Physical method for containment in which a leaking or damaged container, drum, or vessel is placed inside a larger, specially constructed container. Overpacking.
Placing material over a breach and holding it in place to stop flow. Patching.
Inserting, driving, or screwing a chemically compatible object into the breach of a container to reduce or temporarily stop the flow. Plugging.
Physical or chemical method of containment by which the internal pressure of a closed container is reduced. Pressure isolation and reduction.
Physical method of confinement by which a liquid is temporarily contained in an area where it can be absorbed, neutralized, or picked up for proper disposal. Retention.
Causing a liquid to solidify. Solidification.
Physically moving a liquid, gas or some forms of solids either manually, by pump, or by pressure transfer. Transfer.
Physical method of control by which water spray or fans are used to reduce the concentration of a gas below the LEL. Vapor Dispersion.
Physical method of control to reduce or eliminate the vapors emanating from a spilled or released material. Vapor Suppression.
