Preparing Fleet Technicians for Safe, Effective CNG Vehicle Service

 

Just as understanding electrical and mechanical systems is essential in conventional vehicles, having thorough knowledge of CNG system principles, components, and hazard control practices is critical for the safety of fleet technicians, and proper maintenance of CNG-powered medium- and heavy-duty vehicles.

 

WTA’s CNG Fuel Systems training for fleet technicians focuses on technician-permitted service activities, including safe handling, system inspection, leak detection, and troubleshooting procedures relevant to CNG-powered work trucks, buses, and vocational fleet vehicles.

​

Technicians who complete this training will understand how to service CNG fuel systems within the scope of technician-permitted activities, minimizing risk and ensuring fleet safety and performance. Fleet managers will gain confidence that their maintenance teams can apply industry-aligned best practices and safety protocols to CNG vehicles with competence and care.

​

Compressed Natural Gas (CNG) is a widely adopted alternative fuel for medium- and heavy-duty fleet vehicles, offering a cleaner-burning and efficient energy source. CNG fuel systems operate at high pressures and incorporate unique components such as cylinders, regulators, high-pressure lines, valves, and safety devices. Technicians servicing these systems must have the knowledge to inspect, diagnose, and service them safely and correctly to maintain vehicle uptime and safety.

​

Prepare your team with the technical expertise to keep medium- and heavy-duty CNG fleets safe, reliable, and operating at peak performance with WTA’s CNG Fuel System Maintenance Course for fleet technicians.
