Loss of suit integrity Loss of verbal comm Buddy down in hot zone |
|
|
Absorption
|
process by which materials hold liquids
|
|
|
Adsorption
|
Substance attracts and holds another; produces heat and can spontaneously combust
|
|
|
Dilution
|
reduces concentration of contaminent; best used with water soluble materials
|
|
|
Disposal
|
direct removal of a contaminent from a carrier; may not remove all contamination
|
|
|
Chemical Degradation
|
natural breakdown of the contaminants as they age
|
|
|
List and describe the two ways to decontaminate something.
|
1 ) Physical - manually separate the chemical from material contaminated by scrubbing/washing
2) Chemically - adding another chem to change the properties of one chem into another to facilitate its removal |
