For consumer's safety, the National Fire Protection Association enacted code changes concerning certain propane tanks. These code changes appear in "NFPA 58," a booklet 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-sized propane cylinders.
These cylinder sizes are typically 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 safe propane refilling and reduce 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.
Additionally, residents with propane tanks for disposal may do so by writing "RECYCLE" on the tank and taking it to any Blue Rhino location. Blue Rhino will collect the tank and refurbish it if possible; if the tank does not meet safety and quality standards they will simply recycle the tank. Standard sized (20lbs.) propane tanks of any brand are accepted at Blue Rhino locations and there is no charge to participate in their program. To find a Blue Rhino location nearest you, Click Here.
