SCG Liquid Propane Overfill Protection Devices (OPD valves)
Check against the official notice below — it lists the full affected range.
SCG Miyairi overfill protection devices used on certain 20-pound liquid propane gas cylinders pose a fire hazard. When a cylinder is filled to capacity and exposed to heat, liquid propane can leak instead of gas vapor, causing the gas regulator valve to freeze. When the valve thaws, if it hasn't been turned off, gas will flow into the grill and accumulate, creating a serious fire risk. The recalled devices are marked with "V5QA OPD" on the body and handle, along with either "DT 3.8" or "DT 3.8A" and date codes "07-02," "08-02," or "10-98" on the wrench pad. The cylinders themselves, manufactured by Sahamitr in Thailand and marked "SMPC DOT-4BA240" with serial numbers between 375201 and 396800, are not hazardous.
Consumers who have one of the recalled units should stop using the gas cylinders immediately and contact SCG. The company will direct callers to a local LP gas exchange center, which will replace the cylinder with one featuring a new OPD valve. Consumers should not attempt to remove the OPD or gas valve themselves and should not take the LP gas cylinder to a standard LP gas refiller.

When the cylinder on the gas grill is filled to capacity and exposed to increased temperatures, liquid propane, instead of gas vapor, can leak out and cause the gas regulator valve to freeze. When the regulator valve thaws, if it has not been turned off, gas will flow to the grill. The resulting build-up of gas in the grill can pose a serious fire hazard to consumers.
Consumers should stop using the gas cylinders immediately and contact the company. SCG will identify, for callers who have one of the recalled units, a local LP gas exchange center, which will replace the cylinder with one that has a new OPD valve. Do not take the LP gas cylinder to an LP gas refiller. Consumers should not attempt to remove the OPD or gas valve themselves.
The recalled SCG Overfill Prevention Devices (OPD) have "V5QA OPD" engraved on the body and handle and either "DT 3.8" or "DT 3.8A" printed on one side of the wrench pad and "07-02," "08-02," or "10-98" printed on the other side. The valves are installed on 20-pound liquid propane gas cylinders manufactured by the Sahamitr Pressure Container Public Co. Ltd. in Thailand. The cylinders are marked "SMPC DOT-4BA240" and have a serial number in the range of 375201 to 396800. There is no hazard with the cylinders.
