solids & Gas "no need for Mask"
is CPS considered "Down" if doors are open? true or False true
what is a Not pressurized but provides protection against
what is Limited Protection "LP"
Solids & liquids only?
"if installed" what will instantaneously close in response
what is a Anti-Blast Valve
to the shock front & reopen once shock wave has passed
A Space between the air intake & filter housing assembly
what is "Dirty Side Plenum"
for access to the filters

to stop/prevent the pre-cooling coils from Freezing
&
what does the Preheater do?
has weather intake air to avoid forming condensation & to
provide relative humidity control
what type of filter is installed in each CBR Filter Housing? Pre-filter
what does the Prefilter Reduce? loading on the CBR HEPA filter

what does the HEPA Filter consist of/ what does it do?
Aerosol CBR Contaminats
what is the Flow rate of the HEPA Filter? 200 Cubic Fpm "feet per minute"
contains activated Carbon for removing chem warfare
what is the Gas Absorber Filter contain & what does it do?
gases.
what regulates the pressure in a Zone? Pressure Control Valve "PCV"
, what is the set point does the PCV need to exceed to open? 2.0 in/wg
a Small controlled chamber situated at zones boundaries
What is an Airlock? & allow personnel to transit in or out of zones without
reducing pressure.
3 types
Type I - TP to Weather Deck only for exit.
how many types of Airlocks are there an what do they do? Type II - TP to LP "swept continuously from top to bottom
& across airlocks"
Type III - TP to TP "connects 2 CPS TP zones, can become
a Type II"
what is the difference Between an Airlock & a Pressure Airlock - has air sweep
Lock? Pressure lock - doesn't
from a TP zone to other parts of the ship "only during an
when can Pressure locks be used? Uncontaminated environment & must not after CBR attack"
Not During or after CBR Attack.

"in book only says 4in"
-when Zone in not pressurized
when can water be filled into Drain Traps? what does it
&
prevent?
- to prevent water blowing out
where is Master control panel located? an what does it
