When inspecting PE (polyethylene) pipe fusion joints, which visual characteristic indicates an acceptable butt fusion weld?
Answer: Uniform double rollback bead with no voids or gaps
An acceptable butt fusion joint shows a uniform, symmetric double rollback bead on both sides of the joint, indicating proper heat and pressure were applied.
BGE crews are replacing a section of cast iron gas main. What minimum pressure test is typically required before returning the line to service?
Answer: A pressure test at 1.5 times the maximum allowable operating pressure (MAOP)
Federal pipeline safety regulations (49 CFR Part 192) require a pressure test at a minimum of 1.5 times MAOP to verify integrity before returning gas lines to service.
An inspector notices a gas meter set installed closer to a window opening than code allows. Which step should be taken first?
Answer: Document the deficiency and notify the responsible supervisor
The first step is to document the non-conformance and notify the supervisor so a corrective action plan can be developed per QC procedures.
During electric cable splicing inspection, what is the purpose of verifying the correct torque on compression connectors?
Answer: To confirm the connector will carry the rated current without overheating or failing
Correct torque on compression connectors ensures low-resistance, mechanically secure connections that prevent overheating and connection failure under load.
What is the primary reason BGE requires photographic documentation during trench inspections?
Answer: To provide a verifiable record of installation conditions and compliance at the time of inspection
Photographs create an objective, time-stamped record of actual field conditions that supports compliance verification, dispute resolution, and regulatory audits.
A pipe coating inspection using a holiday detector finds a discontinuity (holiday) in the coating. What must occur?
Answer: Repair the holiday and re-test the repaired area before backfilling
All coating holidays must be repaired and re-tested prior to backfilling to ensure continuous corrosion protection.
Which federal regulation governs the inspection and testing requirements for natural gas distribution systems operated by utilities like BGE?
Answer: 49 CFR Part 192
49 CFR Part 192 (Transportation of Natural and Other Gas by Pipeline) sets minimum federal safety standards for gas pipeline design, construction, testing, and inspection.
