| One of the most important parts of any propane container is the container markings. On an ASME container, this information is on a data plate. The data plate carries information vital to the identification and safe use of the container and should be securely attached to the container. If a customer should request that you fill an ASME tank with a missing or illegible data plate and cannot produce a data sheet for the tank, you should refuse -- for their protection and yours.
Container data plates are required to give you the following information about the propane container:
 NAME AND ADDRESS OF MANUFACTURER
TYPE OF SERVICE OR INTENDED USE
MAXIMUM ALLOWABLE WORKING PRESSURE
WATER CAPACITY IN GALLONS
OUTSIDE SURFACE AREA OF TANK (IN SQUARE FT.)
Also, the date plate must contain the wording: "THIS CONTAINER SHALL NOT CONTAIN A PRODUCT HAVING A VAPOR PRESSURE IN EXCESS OF _ PSIG AT 100 0 F. "
Other information, such as the year of manufacture, head and shell thickness, length of the tank, serial number, material of construction, dip tube length, etc, may also be found on the container data plate . |
