CERTIFICATION EXAM ACTUAL EXAM 200 QUESTIONS AND
CORRECT DETAILED ANSWERS |AGRADE
What problems may occur when a person works in a very hot area for a prolonged
period of time? - ANSWER-Heat stroke, Cramps, Exhaustion
What is the purpose of a confined space safety permit? - ANSWER-It ensures the
use of safety precautions and use of standard safety procedures when working in
a confined space
Why must preventative maintenance tasks be documented? - ANSWER-Records
are needed to show the type and frequency of maintenance of operating units
and to evaluate the effectiveness of maintenance programs
True or False : When accepting a work order, the need for speedy completion is an
integral aspect of your performance as a Maintainenance Technologist - ANSWER-
FALSE : It does not matter how long it takes to complete a work order, the most
important and integral aspect of your performance when completing a work order
is doing it safely and compleately
There is an 18" wide red stripe painted on the ground around a tank. The tank is
25' high and 150' in diameter. What is the perimeter on the outer edge of the
stripe? - ANSWER-475.71 ft
18" = 1.5'
Perimeter = Diameter * pi = (150' + 1.5') * 3.14 = 475.71

A 12" diameter pipe, 48' long, weighs 35lbs per linear ft. What is the weight of the
total load? - ANSWER-1680 lbs/ft
48' * 35lbs = 1680
What is the definition of Arc Welding? - ANSWER-Arc Welding is a welding process
that is used to join metal to metal by using electricity to create enough heat to
melt metal, and the melted metals, when cool, result in a binding of the metals
How does a centrifugal pump work? - ANSWER-Moves fluid by means of rotational
energy from rotor drives/impellers. Fluid enters the rapidly rotating impeller along
its axis and is cast out by centrifugal force along its circumference through the
impeller's vein tips
What is centrifugal force? - ANSWER-An outward force on a mass when it is
rotated
How does a positive displacement pump work? - ANSWER-Pump moves fluid by
repeatedly enclosing a fixed volume of fluid, with the aid of seals or valves, and
moving it mechanically (with a piston or a plunger) through a system
How does a vacuum pump work? - ANSWER-Vacuum pumps have an inlet and and
outlet with a nozzle in between - the nozzle restricts flow of fluids, thereby
increasing fluid's velocity and decreases the fluids pressure. A vacuum is created
by the lack of pressure which pulls the fluid into the nozzle and forces it out the
other side

What types of coatings are usually used on the inside of wet wells? - ANSWER-
Epoxy coatings
What is a wet well? - ANSWER-A tank, a portion of a water system that
temporarily stores water before it is pumped elsewhere
What is an oxygen-acetylene torch? - ANSWER-A welding torch that uses fuel gas
and oxygen to weld or cut metals
What does CMMS stand for? - ANSWER-Computerized Maintenance Management
System
What does OMM stand for? - ANSWER-Operations and Maintenance Manual
What does SOP stand for? - ANSWER-Standard Operating Procedure
What does SCADA stand for? - ANSWER-Supervisory Control and Data Acquisition
What does SDS stand for? - ANSWER-Safety Data Sheet
What does LOTO stand for? - ANSWER-Lock Out Tag Out
What does PPE stand for? - ANSWER-Personal Protective Equipment (PPE)
