NICET ITWBS Level III Practice Questions - NICET Inspection and Testing of Water-Based Systems Level III Exam - NICET ITWBS Level III Practice Questions - NICET Inspection and Testing of Water-Based Systems Level III Exam

Question 1

Under NFPA 25 (2023), how often must a deluge valve be trip tested at full flow under normal conditions?

Quarterly, with the control valve partially open to limit discharge Annually, at full flow during warm weather Every 3 years, at full flow Every 5 years, in conjunction with the internal piping assessment

Correct Answer:

Annually, at full flow during warm weather

Question 2

A deluge system protects a turbine lubricating-oil skid where water discharge would damage the equipment unless the unit is shut down. Per NFPA 25, full-flow trip tests must be coordinated with plant shutdowns, but the interval between full-flow tests must not exceed:

1 year 2 years 3 years 5 years

Correct Answer:

3 years

Question 3

A technician proposes trip testing a deluge valve with a partial-flow trip each year and a full-flow trip only every 3 years, 'the same way we do the dry pipe valves.' As the Level III supervisor reviewing the plan, you should:

Reject it — the annual full-flow trip requirement applies to deluge valves; the annual partial-trip/3-year full-trip schedule applies to dry pipe valves Accept it — NFPA 25 treats deluge valves and dry pipe valves identically for trip testing Accept it as long as the AHJ is notified in writing before each partial trip Reject it — deluge valves only require a full-flow trip every 5 years alongside the internal assessment

Correct Answer:

Reject it — the annual full-flow trip requirement applies to deluge valves; the annual partial-trip/3-year full-trip schedule applies to dry pipe valves

Question 4

A double interlock preaction system protects a -10°F freezer warehouse. How does NFPA 25 direct the annual trip test to be performed?

Skip the trip test entirely until the freezer is decommissioned Trip the valve at full flow so ice formation can be observed directly Trip test only the releasing panel and leave the valve untouched Conduct the trip test in a manner that does not introduce moisture into the piping within the freezer

Correct Answer:

Conduct the trip test in a manner that does not introduce moisture into the piping within the freezer

Question 5

On a double interlock preaction system, water is admitted to the system piping only when:

The detection system operates or supervisory air pressure is lost, whichever occurs first Both the detection system operates and supervisory air pressure is lost (such as from a sprinkler opening) A manual release is pulled, regardless of detection or air status The fire department connection is pressurized by a pumper

Correct Answer:

Both the detection system operates and supervisory air pressure is lost (such as from a sprinkler opening)
