NGVi Introduces CNG Fuel System Inspector Certification Program
Natural Gas Vehicle Institute (NGVi) has launched its certification program for compressed natural gas
(CNG) fuel systems, which provides an independent assessment to ensure technicians possess the
knowledge, skills and specific competencies required to conduct CNG fuel system inspections according
to all federal codes and standards and industry best practices.
According to NGVi, the program was designed according to the requirements for professional
certification programs prescribed by the National Commission for Certifying Agencies and certifies
technicians for a period of five years.
The institute states that regular inspections of all CNG cylinders are required by Federal Motor Vehicle
Safety Standard 304 and that NGV industry best practices recommend inspection of the entire fuel
system. These inspections must be performed by qualified CNG fuel system inspectors and in
accordance with the manufacturer’s recommendations and Compressed Gas Association pamphlet C-
6.4.
“While there is no national requirement that CNG Fuel System Inspectors be certified, certification
offers that extra layer of assurance and risk mitigation in the operation and maintenance of any CNG-
powered vehicles,” says Leo Thomason, executive director of NGVi.
The institute says that qualified CNG Fuel System Inspectors must be able to thoroughly inspect all
components of CNG fuel systems, correctly document their findings, assess any damage and determine
the proper steps necessary to ensure that fuel system safety is maintained. They also must be familiar
with and able to effectively use a variety of inspection documents, including applicable codes, standards,
regulations, specific manufacturer guidelines, as well as industry best practices.
“We are proud to say that our rigorous certification program was carefully designed and specifically
developed to assess the knowledge and skills these technicians must apply during an actual inspection.
Our certification exam was created based on a detailed job study of tasks required to be performed by
CNG Fuel System Inspectors,” says Thomason.
NGVi’s CNG Fuel System Inspector program was developed and will be administered independently from
its training programs, and there is no training prerequisite for technicians who seek certification. To
ensure quality, uniformity and impartiality, the certification program is overseen by an independent
Advisory Board comprising CNG cylinder, fuel system and vehicle manufacturers, as well as end users.
The Advisory Board includes representatives from Hexagon Lincoln, Worthington Industries, Agility Fuel
Systems, Penske Truck Leasing, Waste Management, UPS and Volvo.
The certification exam will be offered live at various locations throughout the country, as well as via an
online, electronically proctored exam that can be scheduled individually and taken at a time convenient
for the participant.
“Another great advantage of our certification program is its accessibility,” says Thomason. “The live-
proctored paper exam will be offered in at least six separate locations throughout the country during
the fourth quarter of 2016, in addition to monthly offerings at our headquarters. To make the
certification experience even more convenient, we have added an online, independently proctored
option, allowing participants to take the exam from their own computers.”
