What is a key requirement for nameplates on containers built prior to September 1, 1984?

The requirement for nameplates on containers built prior to September 1, 1984, emphasizes that they must be made of stainless steel and permanently attached by fusion welding. This specification is important for ensuring the durability and longevity of the nameplate, as it should withstand various environmental conditions without deteriorating. The use of stainless steel helps prevent corrosion, which is critical given that these containers often hold volatile substances. Additionally, the requirement for the nameplate to be permanently attached ensures that the necessary information remains accessible and unaffected by external factors, thereby promoting safety and proper identification of the container’s contents. This standard reflects regulatory practices aimed at maintaining safety in the handling and storage of LP gas.
