[WARNING] Protect against extremely cold escaping CNG. Compressed
natural gas is stored at an extremely high pressure. If compressed natural gas
escapes from a leak, it will expand into an extremely cold (-260° F) gas. Severe
frostbite may occur from contact with escaping natural gas or its associated
components. Avoid the hazard by relieving the pressure before disconnecting
any CNG fitting or line. Properly tighten all connections and thoroughly check
for leaks before applying pressure.
[WARNING] Storage tanks must be tested according to specified procedures
at required dates. Failure to do so relieves the manufacturer of all responsibil-
ity and is a violation of federal law. See the manufacturer's label.
[WARNING] After an accident, all tanks, lines, and fittings should be thor-
oughly checked by qualified personnel before the vehicle is used again.
All valves are closed when turned fully clockwise (viewed from the top of the
valve handle), and open when turned counterclockwise (viewed from the top of the
valve handle).
[WARNING] Always provide good ventilation, including near the roof and/or
the ceiling. Avoid working in noisy environments, because the sound of leak-
ing gas may go undetected.
[WARNING] Never attempt to find a leak with your hands. A large leak can
freeze burn the skin. Never place your hands, or any other part of your body,
on a leak.
Always have the properly rated fire extinguishers at hand. Be that certain auto-
matic fire suppression equipment is in place and in operating condition.
[WARNING] Avoid heat near pressure relief valves. The manufacturer's rat-
ing is 212° F for the relief valve. If it vents, the area will be filled with natural
gas.
[WARNING] Rust or corrosion on tanks, lines, fittings, and valves can be a
serious problem. Any part with serious corrosion should be replaced. Fiber-
glass coating on tanks should be in excellent condition. Any cracks or serious
scrapes may require tank replacement. Contact the manufacturer.
[WARNING] Tanks cannot be filled to more than 3,000 psi or 3,600 psi
temperature-corrected. Use only authorized refueling stations with adequate
pressure controls and venting capacity. Venting contents of tanks should fol-
low any federal and state guidelines, including EPA.
