Hazards
The following hazards may occur when exchanging propane cylinders on the forklift truck:
Cold burns
Musculoskeletal disorder (handling the cylinder)
Chemical exposure (carbon monoxide from incomplete combustion)
Fire or explosion
Displacement of air
Personal Protective Equipment
Eye protection
Neoprene gloves
Long sleeve shirt
Safe Operating Procedure
Propane cylinders must be approved by Canadian Standards Association (CSA) or Underwriters Laboratories of Canada (ULC)
Must be less than 10 years old or re-certified
Must not be dented, gouged or rusted
Cylinders may be used indoors provided that:

Not near exit, stairway or evacuation route.
Fire extinguisher is accessible.
Safety Features for Equipment
PCL threaded connector:
Put-on-left threaded connector
Only special gas fittings can be connected
Relief valve
Releases excess pressure from the cylinder if pressure exceeds 375 pounds per square inch.
Regulator
Reduces propane pressure to the range the appliance was designed for, usually less than 30 pounds per square inch.
Excess flow check connector
Cuts off propane flow when the flow is very high, such as when there is a cut in the hose.
Flame safeguard system
Is required when appliance is left unattended. Note: never leave a forklift unattended when it is running.
Cuts off the propane flow if the flame extinguishes for any reason.
Prevents the build-up of propane and reduces the risk of explosion.
