|
Chemical: the weakening of a material by exposure to chemicals
Physical: weakening or destruction of a material caused by rubbing against rough surfaces |
|
|
Penetration of a suit refers to what?
|
The movement of a chemical through the suit's closures, cracks, or tears
|
|
|
Permeation of a suit refers to what?
|
The process by which a hazardous material moves through a given material on the molecular level.

|
3 hours
|
|
|
What are some indications of degradation of PPE clothing

Stiffness or excess pliability, tears, cuts or abrasions, damage to zippers or closures, soft sticky areas.
|
|
|
What are the three types of cooling systems in PPE suits?
|
Air cooled, Ice cooled, Water cooled.
|
|
|
what are some psychological stresses that can affect users in PPE
|
Low dexterity mobility, low visibility, communication problems, physical stress, claustrophobia, limited dexterity, and heat stress.
|
|
|
how would you describe Absorption when referring to decontamination
|
to absorb liquid contaminants without changing their properties
|
|
|
what is a disadvantage of absorption?
|
absorbed contaminant remains hazardous
|
|
|
what could you use to absorb a chemical?
|
Soil, sand, and absorbent pillows/pads
|
|
|
What is Adsorption?
|
Contaminant sticks to the sorbent material without adding to the volume of the sorbent. The resulting chemical reaction is heat
|
|
|
What is a disadvantage of Adsorption?
|
causes heat, that could cause spontaneous combustion
|
|
|
What is Chemical Degradation?
|
Waiting to allow a chemical to lose potency.
|
|
|
what is Dilution?
|
adding a non-hazardous liquid solution, to lower the concentration
|
|
|
what is a disadvantage of Dilution
|
Could increase the size of the risk, may need a large amount of non-hazardous liquid.
|
|
|
What is Evaporation
|
To allow a chemical to evaporate
|
|
|
What is neutralization?
|
To add a chemical to a contaminant, in order to change the chemical structure. for example adding a base to an acid to neutralize it.
|
|
|
What is solidification?
|
To add a chemical to the contaminant that will convert its physical sate from liquid to solid
|
|
|

|
To gather the contaminant by sucking it from the surface and hard to reach areas. (mostly used in radiological fallout)
