25
How do you calculate air consumption for SCBA entry teams?
Measure RMV under stress, multiply by tank capacity, and add safety margins.
26
How do organic vapor cartridges differ from CBRNE canisters?
Vapor cartridges filter hydrocarbons; CBRNE canisters filter multiple threats, including chemical agents.
27
What is permeation lag time, and why is it important for gloves?
The delay before chemicals pass through gloves; defines exposure risk timing.
28
Why does Viton outperform butyl for chlorinated solvents, and when is butyl preferred?
Viton resists chlorinated solvents; butyl is better for gases and acids.
29
Why are Silver Shield gloves unsuitable for high-mechanical tasks?
They tear easily and have poor dexterity.
30
What does the breakthrough detection threshold indicate in glove testing?
The lowest detectable chemical concentration inside the glove.
31
Why do boots require chem tape at the suit interface?
To block contaminants from wicking into gaps via capillary action.
32
When is a multi-layer glove system required?
When one layer resists chemicals and another provides mechanical strength.
33
Why is flame resistance critical for hazmat suits in industrial fires?
Reduces ignition risk from flashover or vapor fires.
34
How does fit testing differ for particulate vs. vapor hazards in Level C APRs?
Vapor: irritant smoke/banana oil; particulate: particle counter tests.
35
What must be considered when reusing decontaminated PPE?
Material degradation, residual contamination, and structural integrity.
36
What is the adsorption saturation point for activated carbon filters?
The point where the filter fails to absorb more contaminants, risking breakthrough.
37
Why is chem tape unsuitable for cryogenic environments?
It becomes brittle and loses adhesion in extreme cold.
38
Why are PFA-lined suits superior for hydrofluoric acid?
PFA resists HF, unlike standard Level A materials that degrade rapidly.
