Question | Answer |
---|---|
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. |
