NDT Safety Protocols & Compliance Regulations 2 — Questions and Answers
Question 1: Under OSHA 29 CFR 1910.146, which condition classifies a space as a permit-required confined space in a boiler?
- Contains a hazardous atmosphere or engulfment hazard (Correct answer)
- Has a restricted entry point only
- Requires a ladder for entry
- Is located below grade level
Correct answer: Contains a hazardous atmosphere or engulfment hazard
OSHA 1910.146 classifies a space as permit-required if it contains or has the potential to contain a hazardous atmosphere, a material that could engulf an entrant, or other serious safety hazards.
Question 2: Which ASME standard governs the inspection and testing of boilers and pressure vessels used in NDT evaluations?
- ASME Section V (Correct answer)
- ASME Section VIII
- ASME Section I
- ASME Section IX
Correct answer: ASME Section V
ASME Section V (Nondestructive Examination) establishes requirements and methods for NDT of boilers and pressure vessels.
Question 3: A boilermaker NDT technician discovers a crack during an inspection but has not yet filed the required documentation. What must happen before work resumes?
- The finding must be documented and reviewed by a qualified inspector before resuming (Correct answer)
- Work can resume if the crack appears minor
- The supervisor can verbally authorize continuation
- A new NDT test can replace documentation
Correct answer: The finding must be documented and reviewed by a qualified inspector before resuming
All findings must be formally documented and reviewed per applicable codes before any work resumes to maintain compliance and safety accountability.
Question 4: What is the primary purpose of a Job Hazard Analysis (JHA) conducted prior to NDT work on a boiler?
- To identify potential hazards and establish controls before work begins (Correct answer)
- To record the names of all workers on site
- To schedule maintenance windows
- To determine equipment rental costs
Correct answer: To identify potential hazards and establish controls before work begins
A JHA systematically identifies hazards associated with each task step and establishes controls to eliminate or mitigate those hazards before work starts.
Question 5: Which federal agency has authority to enforce radiation safety regulations when radiographic testing (RT) is performed on boilers?
- Nuclear Regulatory Commission (NRC) (Correct answer)
- OSHA
- EPA
- NIOSH
Correct answer: Nuclear Regulatory Commission (NRC)
The NRC regulates the use of radioactive materials including industrial radiography sources, and states with Agreement State status enforce equivalent rules.
Question 6: When using magnetic particle testing (MT) near flammable materials in a boiler, what safety precaution is mandatory?
- Eliminate ignition sources and ensure adequate ventilation before applying wet MT fluids (Correct answer)
- Apply MT fluid rapidly to minimize exposure time
- Disable smoke detectors to avoid false alarms
- Increase ambient temperature to improve fluid flow
Correct answer: Eliminate ignition sources and ensure adequate ventilation before applying wet MT fluids
Wet MT fluids are often petroleum-based and flammable; eliminating ignition sources and ventilating the area prevents fire hazards.
Question 7: A boilermaker NDT technician notices a coworker has bypassed a lockout/tagout (LOTO) device. What is the correct immediate action?
- Stop work, notify the supervisor, and restore LOTO before continuing (Correct answer)
- Continue work but document the violation after the shift
- Ask the coworker to replace the device when convenient
- Proceed if the energy source appears de-energized
Correct answer: Stop work, notify the supervisor, and restore LOTO before continuing
LOTO violations require immediate work stoppage and supervisor notification to prevent accidental energization injuries before work can safely resume.
