Propane tanks disp
For consumer's safety, the National Fire Protection Association enacted some code changes concerning certain propane cylinders. These code changes appear in "NFPA 58," a book of National Fire Protection Association codes published for the propane industry.
As of April 1, 2002, an Overfill Prevention Device (OPD) valve is required on typical 4# to 40# size propane cylinders.
This size cylinder is usually used to fuel outdoor grills, camp stoves, etc. After April 1, 2002 these cylinders cannot be filled without the OPD valve.
The OPD valve is a float-activated device designed to assist propane refilling to safe levels, thus reducing the possibility of hydrostatic relief valve discharges.
Propane cylinders with an "OPD" valve can be easily identified by looking for the "OPD" stamp on top of the handwheel.
If your municipal recycling center does not accept propane tanks, please contact your local propane distributor for proper disposal or exchange of your propane tank.
