What are the 2 factors regarding Permiation
Breakdown Time
Permeation Rate
How is Breakdown time measured
In minutes
The amount of a chemical which passes through a given area of clothing per unit of time.
Permeation Rate
What are the 4 factors that influence permeation
- Temp
- Thickness of material
- Concentration of chemical
- Multi-component Liquid
The flow of a chemical through closures, seams, and pinholes or other imperfections in a protective clothing on a non-molecular level
Penetration
The elapsed time from initial contact on the outside surface of the CPC to the first detection of chemical on the inside surface
Breakthrough time
The amount of a chemical which passes through a given area of clothing per unit of time
Permeation Rate
A deleterious change in one or more physical properties of a protective clothing material due to contact with a chemical
Degredation
What are the signs of degredation
- Discoloration
- Tackiness
- Cracking
- Bubbling
- Stiffness
List the 4 Emergencies Working in CPE
- Loss of air in SCBA
- Loss of comms with partner
- Integrity breach of CPE
- Bodily Injury
The physical and chemical properties that contribute to the unacceptable risk to health, safety, and environment.Any Material capable of causing harm
Hazard
The process by which people and equipment are subjected to or com in contact with a hazardous material.
Exposure
The process of transferring a hazardous material from its source to others
Contamination
the process by which the haz mat is carried outside of the control zone and is transferred from one to another.
Secondary Contamination
Wheat are the 4 main reasons for decontamination
- decon can be performed at any time an exposure to haz mat may have or is known to have occurred
- obvious contamination of a surface
- There is suspected contamination of a surface by a hazardous material
- there is even a minimal likelihood of exposure to a haz mat.
7 physical methods of decontamination
- Brushing
- Dilution
- Scraping/Scrubbing
- Sorption
- Absorption
- Adsorption
- vacuuming
