SOLUTION 2026 QUESTIONS WITH ANSWERS
GRADED A+
◉What is one cause of an ineffective maintenance program? Answer:
Airtight joint
◉Which items are sources of pressure on the financial resources of a
wasterwater collection system agency? Answer: Reduction of a federal,
state, and local funds
◉What problem can occur when velocities in a collection system are too
high or too low? Answer: The velocities can interfere with the operation
and maintenance of the system
◉What are lateral and branch sewers? Answer: Sewers that serve the
upper ends of the street sewer components of a collection system
◉Why must building sewer connections be constructed with care?
Answer: To avoid sources of ground water infiltration and sewer
stoppages
,◉When operators review collection system designs, which factors
should be considered? Answer: Manhole locations
◉What kind of training should each person whose actions affect TTC
zone safety receive? Answer: Training appropriate to the job decisions
each individual is required to make
◉What is a TTC plan? Answer: A description of traffic control to be
used for facilitating all traffic through a TTC zone
◉When are governing road authorities most likely to restrict
construction work in streets? Answer: Peak traffic periods
◉In what area should work activity and storage of equipment, vehicles,
and materials not occur? Answer: Buffer space
◉What is one way to minimize the possibility of temporary traffic
control cones being blown over or displaced by wind or moving
vehicular traffic? Answer: Apply retroreflective tape or equip with
lighting devices
◉Which item is not a major category of hazards? Answer: Insect, bug,
rodent, and snake bites
, ◉What is the major concern in confined spaces? Answer: Whether the
existing ventilation is capable of removing atmospheric hazards that may
exist or develop
◉When using atmospheric analyzers to test the air in confined spaces, in
what order should test be performed? Answer: Oxygen content,
combustible gases and toxic gases

instrument be replaced periodically? Answer: It loses its sensitivity to
hydrogen sulfide

first? Answer: Top brace or jack
◉If the human body becomes a variable resistor, what determines the
amount of damage the electric current does to the body Answer: The
amount of current that flows through the body
◉Which diseases can be caused by bacteria that may be present in
untreated domestic wastewater? Answer: Cholera and typhoid fever
◉Gravity flow Answer: Water or wasterwater flowing from a higher
elevation to a lower elevation due to the force of gravity
