Define the term "clear and bright." - CORRECT ANSWER✅✅Clear is the absence of particulate matter
(sediment),

When are LO samples required? - CORRECT ANSWER✅✅24 hours prior to start,
Daily while operating (include equipment in auto start),
Upon receipt of new oil,
Within 24 hours prior to transfer or oil,
When unusual conditions exist,
After an equipment casualty,
Test purifier sample 30 minutes after starting and at least one every four hours,
Equipment with sump capacities with 1 gallon or more
Discuss the requirements for a lube oil sample drawn from the MRG LO System - CORRECT
ANSWER✅✅The MRG LO system is purifiable and therefore a sample is UNSAT if it fails to meet the
clear and bright test. The system can still be operated and a BS&W must be conducted. The system must
be placed on purification. Refer to NSTM 262 for flow chart and more details
Discuss the requirements for a lube oil sample drawn from the CPP LO system - CORRECT
ANSWER✅✅This uses NSTM 245 to determine sample criteria. A sample is considered UNSAT after it
fails the BS&W test with more than .1 SED and more than .4 comb
Discuss the requirements for lube oil sample drawn from a LSB - CORRECT ANSWER✅✅This is a non-
purifiable system/sump. If the sample fails the clear and bright, the transparency test or the visible
sediment test must be preformed. If it still fails those test then a BS&W test must be performed and if it
is less than .1 SED and less than .4 comb it is an SAT sample
At what speed and how long is the centrifuge used for when conducting a BS&W test? - CORRECT
ANSWER✅✅1500 RPM for 30 minutes
,How do you conduct a transparency test on non-purifiable samples? - CORRECT ANSWER✅✅Place a
PMS card behind bottom and read, if it can be read the sample is SAT
How do you conduct a visible sediment test? - CORRECT ANSWER✅✅Let bottle sit for 10 minutes, the
place the bottle on its side for 10 minutes. If sediment is greater than 1/8th an inch or forms a solid line
along the bottom, the sample is UNSAT
How long is the LOQM log kept on board? - CORRECT ANSWER✅✅2 years
What is the testing criterion for fuel filter separator discharge samples? - CORRECT ANSWER✅✅Free
Water Detection test max allowable outcome is 40ppm, contaminated Fuel Detection test allowable
outcome is 2.64mg/L sediment
Discuss the test requirements for a fuel service tank sample - CORRECT ANSWER✅✅clear and bright
Where is the fuel service tank sample drawn from? - CORRECT ANSWER✅✅Filter separator if tank is
online,
Purifier discharge if tank is on recirculation
What is the minimum flashpoint of F-76? - CORRECT ANSWER✅✅140 degF
How often is fuel sampled during normal fuel service system operation? (service tank that is online) -
CORRECT ANSWER✅✅Eight hours prior to use, the filter/separator for the online service tank is tested
5 minutes after tank placed online and every 4 hours after that
What are the maximum limits of BS&W during UNREP? - CORRECT ANSWER✅✅0.1% max
How often are head tank samples taken? - CORRECT ANSWER✅✅Monthly
How is linear motion translated into radial motion in the CPP system? - CORRECT ANSWER✅✅The
crosshead moves in a lineal direction, and is connected to the blades creating the radial motion
,How full can the tanks get during re-fueling operations? - CORRECT ANSWER✅✅95% at sea and 85% in-
port
How long is the FOQM log kept onboard? - CORRECT ANSWER✅✅6 months
How long are the Fuel, Oil and Water reports kept on board? - CORRECT ANSWER✅✅1 year
When is a heat stress survey required? - CORRECT ANSWER✅✅when DB reaches >90 degF,
prior to EOCC drills that will last longer than 3 hrs,
upon CO request,
in the even of a heat stress casualty
When is a follow up heat stress survey required? - CORRECT ANSWER✅✅DB increases or decreases 5
degF from previous surveys
When do you need to rush survey results to the CO? - CORRECT ANSWER✅✅The current watch
rotation exceeds the recommend heat stress stay time
When is a time weighted mean? - CORRECT ANSWER✅✅Allows watch standers to stay in the space
longer by allowing them to take breaks and cool off in a location cooler than the watchstation
When are time weighted means applied during the course of standing watch? - CORRECT
ANSWER✅✅In a hot environment where reduced stay times have been imposed on watch/work
stations
How do you verify an installed WBGT sensor is working properly? - CORRECT ANSWER✅✅DB>WB or
GT>DB
What is the WBGT index? - CORRECT ANSWER✅✅It is the combination of the WBGT, WB, & DB temps,
that actually affect you
, Where are Dry Bulb thermometers required to be hung? - CORRECT ANSWER✅✅Work of watch
stations in which a heat stress environment may occur, Non-ventalated spaces that are normally not
manned, but personnel may work in
Where are the required to be installed within the space - CORRECT ANSWER✅✅In a spot that provides
a good representative sample of the entire spaces temp, should be located at least 2 feet away from any
ventilation sources, shall be hung with a non-metal heat transferring material
What does PHEL stand for? - CORRECT ANSWER✅✅Physiological Heat Exposure Limit
What is the recovery time for personnel who has reached the heat stress exposure limit? - CORRECT
ANSWER✅✅It should be equal to twice the exposure limit or 4 hrs whichever is less
What happens with the exposure of fuel combustion gases/fuel vapors in a space? - CORRECT
ANSWER✅✅The detection of stack gas or fuel vapor reduces the stay time by 2/3 normal time, to
calculate new stay time dived the old stay time by 3
How long does it take a new person to acclimate to the environmental conditions? - CORRECT
ANSWER✅✅3 - 4 weeks
