,• A scale on a blueprint indicates 1" = 2". What does this scale mean? -✓✓Each line on
the blueprint is shown as half of its actual size
• A computerized maintenance management system (CMMS) is a type of .... -✓✓tool
• What problems may occur when a person works in a very hot area for a prolonged
period of time? -✓✓Heat stroke, Cramps, Exhaustion
• What is the purpose of a confined space safety permit? -✓✓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? -✓✓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 -✓✓FALSE : It
does not matter how long it takes to complete a work order, the most important and

• 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? -
✓✓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? -✓✓1680 lbs/ft
48' * 35lbs = 1680
• What is the definition of Arc Welding? -✓✓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? -✓✓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? -✓✓An outward force on a mass when it is rotated
, • How does a positive displacement pump work? -✓✓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? -✓✓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? -✓✓Epoxy
coatings
• What is a wet well? -✓✓A tank, a portion of a water system that temporarily stores
water before it is pumped elsewhere
• What does "galvanized" mean? -✓✓Coated with a protective layer of zinc
• What does PVC stand for? -✓✓Polyvinyl chloride, a type of plastic used for pipes
• What is the formula for horsepower? -✓✓hp = Fd/t
Force (in lbs) multiplied by distance (in feet) divided by time (in minutes)
• What are volts? -✓✓A unit of electric potential
• What is the equation for volts? -✓✓Volts = watts/amps
• What are amps? -✓✓A unit of electric current
• How do you calculate amps? -✓✓Amps = watts / volts
• What are watts? -✓✓A watt is a unit of power
• How do you calculate watts? -✓✓Watts = amps * volts
• What are ohms? -✓✓A measurement of resistance between two points
• How do you calculate ohms? -✓✓Ohms (R) = volts / amps
• What does pneumatic mean? -✓✓Containing or operated by gas or air under pressure
• The specific gravities of gasoline and other volatile solvents are typically
__________________ than water -✓✓less than, meaning they will float
