Day-to-day maintenance of a program keeps you out of what mode?
Crisis management
Using good quality feedwater will help prevent damage to the what?
Boiler watersides
What is the universal solvent as it tends to dissolve everything it touches?
Water
What in feedwater contributes to scale buildup in boilers?
Hardness
Hardness is caused primarily by calcium and what else?
Magnesium
What act as insulators in the boiler?
Scale Deposits
What is an aggressive ion, which attacks and inhibits the formation of the magnetite layer on the boiler metal?
Chloride
What causes localized corrosion and pitting?
Dissolved oxygen
As dissolved oxygen contacts the boiler metal it forms what, which dissolves the metal to form a black iron oxide that covers the pit?
Anode
The navy uses two types of boiler water treatments. The older treatment method is the coordinated phosphate (Cophos) treatment. The newer treatment method is what treatment?
CHELANT
The boiler is a receiver for all contaminants the feedwater system puts into it. One way to prevent these contaminants from damaging the boiler is to precipitate them into what?
Sludge
The Navy uses three treatment chemicals to maintain the phosphate-pH relationship. The chemicals are trisodium phosphate (TSP), disodium phosphate (DSP), and what else?
Caustic Soda
What is used to control pH and add some of the needed phosphate?
TSP
What occurs when there is a pH rise above the Cophos curve?
Free caustic
You use caustic soda as a treatment chemical only in casualty situations and only with the approval of whom?
Chief Engineer
Inject caustic soda at the rate of 1 once per how many gallons of boiler water and only when boiler is steaming?
1,000
All 1200 psi and some 600 psi boilers are designated as what?
Type B
What chelates dissolved metals, including calcium and magnesium, by surrounding and bonding to the metal at several places?
EDTA
Metal chelates are removed from the boiler by continuous what?
Blowdown
Continuous blowdown amounts to about a daily blowdown at what percent of normal boiler loads?
Four
Initial treatment with the CHELANT system is achieved by what?
Batch treatment
The boiler is tested as often as required to maintain limits, but must not exceed what time frame?
24 hours
Who maintains the boiler water/feedwater chemistry?
Oil King
Review of the boiler water/feedwater chemistry logs and records shall be conducted by the main propulsion assistant (MPA) and the Chief Engineer how often?
Daily
Who reviews the monthly water treatment log package?
Commanding Officer (CO)
What is essentially a shipboard laboratory?
Oil Shack
Temperature of the laboratory should be maintained below what temperature?
100 Deg F
The primary fuel tests are visual, bottom sediment and water (BS&W), flash point, and what else?
API gravity
The most common fuel tests are the visual and what?
BS&W
Only water in mechanical suspension is of concern to the engineer. The suspended water is referred to as what?
Free water
What provides spectrometric analysis of lube oil at a designated laboratory?
Navy Oil Analysis Program (NOAP)
A basic requirement of fueling station personnel is a thorough knowledge of what system?
Fuel receiving
Fuel tanks should be filled only to what percent mark?
95
The final soundings, after temperature and gravity corrections, will determine the amount of fuel received, measure the volume and gravity at a standard temperature of what?
60 Deg F
The specific order of refueling is necessary to maintain the ship’s stability. You can find this information in the what?
Ship’s Information Book (SIB)
What has the responsibility of making the final decision on transferring liquid?
DCC
What system allows controlled flooding of designated fuel tanks for stability control?
Ballasting
What is used for ballast?
Seawater
Consult what instruction before pumping contaminated fuel off the ship?
OPNAVINST 5090.1
Newer ships require inspection of one service tank per fireroom every how many months?
36
Never use jury-rigged extension cords, extension cords should not exceed what length?
25 feet

Two
Specific procedures for tag-outs are contained in what instruction?
OPNAVINST 3120.32
Personnel should be trained to notify the EOOW if the dry-bulb temperature reaches or exceeds what in engineering spaces?
100 Deg F
The basic features of an effective training program are compatibility, evaluation and instruction, and what?
Analysis and improvement
