TRANSFER FUELING (DEFUELING) MODES,
COMPONENTS AND PROCEDURES
Defueling is generally the process of removing any residual
fuel from the fuel tanks and on-board fuel delivery system
prior to performing any welding or a major repair. Capturing
the CNG in a system that can send it back to a CNG fueling
station storage facility for reuse is the most environmentally
responsible method. Atmospheric venting of CNG might be
illegal and against local environmental regulations for your
area. Check local laws and regulations before venting CNG
to the atmosphere.
Before attempting to defuel a CNG vehicle, read and
understand National Fire Protection Association (NFPA)
52 sections 6.14.1 - 6.14.4.4 as they provide a detailed list
of requirements to be followed when performing defueling.
Also read and understand all of the safety alert messages
and procedures in this section. Maintenance of a
compressed natural gas system is to be performed ONLY
by authorized service personnel.
Basic Rules for Defueling
Consume as much fuel as possible prior to defueling
Notify appropriate nearby personnel prior to defueling
and clear the area of all unessential people
ALWAYS ground (earth ground) the vehicle AND the
fuel system being defueled
NEVER defuel indoors
Always wear personal protective equipment
Be familiar with evacuation routes
