Core Responsibilities

Primary Functions

Execute the precise installation, maintenance, and complex repair of residential, commercial, and industrial natural gas lines, ensuring system integrity from the main to the meter.
Conduct comprehensive leak detection surveys on gas mains and service lines using advanced electronic equipment, such as flame-ionization or laser-based detectors, and perform necessary pinpointing and grading of any identified leaks.
Respond with urgency to gas leak emergencies and other system failures, taking decisive action to isolate hazards, restore service safely, and protect public and private property.
Perform rigorous pressure testing on newly installed or repaired gas piping systems to verify their integrity and ensure they are free from leaks before placing them into service.
Read, interpret, and work from complex engineering blueprints, construction drawings, and piping and instrumentation diagrams (P&IDs) to accurately locate and work on underground infrastructure.
Skillfully operate light-to-medium excavation equipment, including mini-excavators and backhoes, for the installation and repair of underground pipes, adhering to strict trenching and shoring safety standards.
Perform industry-standard fusion welding techniques (butt, socket, electrofusion) on polyethylene (PE) gas pipes to create durable, leak-proof joints.
Meticulously document all work performed, including parts used, time spent, and as-built sketches, within a Computerized Maintenance Management System (CMMS) for regulatory and asset management purposes.
Ensure all work practices are in strict compliance with federal (DOT, PHMSA), state, and local safety regulations, as well as company-specific operating procedures.
Perform the installation, removal, and periodic exchange of gas meters and regulator assemblies for residential and commercial customers, ensuring accurate billing and safe pressure delivery.
Calibrate, maintain, and troubleshoot the full range of specialized tools and equipment, from gas detectors to pipe fusion machines, to ensure their accuracy and operational readiness.
Investigate and resolve customer-reported gas odor complaints, methodically identifying the source and executing the appropriate corrective actions to mitigate any hazards.
Install, inspect, and service a variety of natural gas appliances for residential and commercial customers, ensuring proper venting, combustion, and safe operation.
Execute a preventative maintenance schedule on critical system components such as valves, compressors, and regulator stations to prevent failures and extend asset life.
Safely isolate sections of the gas grid by closing valves and purging lines with inert gas to create a safe work environment for maintenance, repair, or system upgrades.
Actively participate in all mandatory safety training sessions, emergency response drills, and daily "tailboard" safety briefings to foster a culture of safety-first.
Maintain a well-organized and fully stocked service vehicle, managing the inventory of tools, replacement parts, and essential personal protective equipment (PPE).
Utilize GIS mapping software and locating equipment to precisely identify the position of underground gas infrastructure prior to any excavation activities.
Conduct cathodic protection readings and perform maintenance on anode systems to prevent external corrosion on steel pipelines, a critical aspect of long-term system integrity.
Train and mentor apprentice mechanics on proper procedures, safety protocols, and the use of specialized tools, helping to develop the next generation of skilled technicians.

Secondary Functions

Provide rapid response and expert technical support for ad-hoc operational issues and emergency call-outs, ensuring minimal disruption to service and maximum safety.
Diligently maintain and contribute to the organization's asset management database by accurately documenting all service, repair, and installation activities in the CMMS.
Actively collaborate with engineering, compliance, and customer service departments to translate system needs and regulatory requirements into actionable fieldwork.
Participate in daily tailboard meetings, safety briefings, and weekly planning sessions to coordinate team activities and ensure project milestones are met safely and efficiently.
