BOILERMAKER MAINTENANCE NCCER EXAM WITH CORRECT ANSWERS
Question 1
Which organization requires that a person must be formally trained and certified to operate
personal lifting equipment such as an aerial lift?
A) NCCER
B) ASME
C) API
D) OSHA
E) AWS
Correct Answer: D) OSHA
Rationale: The Occupational Safety and Health Administration (OSHA) sets and enforces safety
standards in the workplace, including the requirement for documented training and
authorization for operators of powered industrial trucks and personal lifting equipment.
Question 2
In which of the following applications would the use of a Ring Type Joint (RTJ) gasket be most
appropriate?
A) Low-pressure water lines
B) High-pressure steam or hydrocarbon systems
C) Gravity-flow drain piping
D) HVAC ductwork
E) Plastic piping systems
Correct Answer: B) High-pressure steam or hydrocarbon systems
, Rationale: RTJ gaskets are solid metal rings designed to create a metal-to-metal seal in
grooved flanges. This design provides a very robust seal suitable for the extreme pressures
and temperatures common in oil, gas, and power generation industries.
Question 3
All of the following are common examples of internal manway hardware EXCEPT:
A) Yoke
B) Davit arm
C) Nut
D) Slide fastener
E) Stud
Correct Answer: D) Slide fastener
Rationale: Yokes, davit arms, nuts, and studs are all standard components used to secure and
handle heavy manway covers on vessels and towers. A slide fastener is not used in these high-
pressure applications.
Question 4
Which threaded pipe fitting is specifically designed to allow for the easy disassembly of a piping
system without having to cut the pipe?
A) Coupling
B) Bell reducer
C) 90-degree elbow
D) Union
E) Nipple
