BI-FUEL MODELS ONLY
WARNING:
^
AVOID INHALING GAS OR OCCUPYING CONFINED AREAS CONTAINING PROPANE. PROPANE IS HEAVIER THAN AIR.
THE HEAVIER GAS CAN DISPLACE OR PUSH FRESH AIR OUT OF AN AREA. IN LARGE QUANTITIES, PROPANE CAN
DISPLACE ENOUGH OXYGEN TO MAKE THE SURROUNDING AIR UNFIT TO BREATHE AND POSSIBLY CAUSE ILLNESS.
IF A PERSON BREATHES PROPANE GAS, HEADACHE, DIZZINESS AND WEAKNESS IN THE EXTREMITIES CAN OCCUR. IN
SEVERE CASES, PROLONGED BREATHING OF PROPANE-FOULED AIR CAN CAUSE SUFFOCATION. IN THE EVENT OF
ILLNESS FROM INHALING PROPANE GAS, MOVE THE VICTIM IMMEDIATELY TO FRESH AIR AND CONTACT A
PHYSICIAN OR MEDICAL EMERGENCY PERSONNEL FOR ARTIFICIAL RESPIRATION OR OTHER REQUIRED
TREATMENT.
^
DO NOT NEEDLESSLY VENT PROPANE FUEL DURING REPAIR AND DO HOT OPEN THE 80% STOP-FILL VALVE WHILE A
VEHICLE IS INSIDE A BUILDING. WHEN REPAIRING THE FUEL SYSTEM, FOLLOW THE RECOMMENDED PROCEDURES
TO SHUT OFF THE FUEL TANKS AND RUN THE ENGINE OUT OF FUEL BEFORE DISCONNECTING THE FUEL SYSTEM
COMPONENTS. IF THE FUEL TANK(S) ARE BEING REPAIRED, HAVE THE FUEL EVACUATED BY TRAINED PERSONNEL
AT A LOCAL PROPANE FUEL STATION. LIQUID PROPANE VAPORIZES AT NORMAL BAROMETRIC PRESSURE AT
TEMPERATURES ABOVE -42°C (-44°F), AND EXPANDS TO 270 TIMES ITS VOLUME AS A LIQUID. UNNECESSARY VENTING
OF PROPANE FUEL CAN CREATE FIRE AND HEALTH HAZARDS WHICH COULD CAUSE PERSONAL INJURY OR DEATH.
^
BE ALERT FOR SITUATIONS THAT MAY CAUSE THE PROPANE FUEL SYSTEM TO VENT FUEL. THESE INCLUDE
EXTREMELY HOT DAYS, PARKING NEAR A SPACE HEATER OR HOISTING A VEHICLE NEAR A CEILING HEATER.
RELEASE OF PROPANE FUEL IN A CONFINED AREA THROUGH THE PRESSURE RELIEF VALVE COULD OCCUR. THE
RELEASE OF PROPANE FUEL IN A CONFINED AREA COULD RESULT IN AN ACCUMULATION OF FLAMMABLE VAPORS.
IF FUEL IS VENTED NEAR A HEAT SOURCE, A FIRE OR EXPLOSION COULD OCCUR.
^
DO NOT USE PAINT DRYING OVENS FOR PROPANE-FUELED VEHICLES. THE HEAT OF PAINT DRYING OVENS WILL
INCREASE THE PRESSURE IN THE FUEL TANKS. THIS COULD CAUSE VENTING OF PROPANE FUEL VAPOR INTO THE
OVEN AND RESULT IN A FIRE FROM THE HEAT OR SPARKS IN THE ELECTRICAL EQUIPMENT. IF THE FUEL IS
CONFINED INSIDE AN OVEN AN EXPLOSION MAY OCCUR. WHEN REFINISHING THE BODY PANELS OF A PROPANE
FUELED VEHICLE, USE SPOT PAINTING AND DRYING METHODS.
^
IF IN A CONFINED AREA, SUCH AS A LUBRICATION PIT, HAS BEEN SUBJECTED TO PROPANE GAS, THE AREA SHOULD
BE INSPECTED FOR ADEQUATE OXYGEN LEVELS BY A LOCAL HEALTH DEPARTMENT BEFORE BEING ENTERED OR
PERSONAL INJURY OR DEATH MAY OCCUR.
^
THE FUEL SYSTEM PRESSURE MUST BE EVACUATED PRIOR TO TANK REMOVAL. REMOVAL OF COMPONENTS
WITHOUT PRESSURE RELIEF OR TANK EVACUATION CAN CAUSE PROPANE FUEL TO ESCAPE INTO THE AIR AND
CAUSE INJURY OR DEATH.
