Containers fabricated to earlier editions of regulations prior to April 1, 1967 shall be what?

Containers fabricated to earlier editions of regulations prior to April 1, 1967 are permitted under specific conditions. This allowance recognizes that many older containers, while designed to earlier standards, can still be functional and safe when maintained properly. The regulations acknowledge the existence of these containers and allow their continued use provided they meet current safety standards and do not present a risk to users or the environment.

Continuing the use of these older containers ensures that existing assets are not wasted and provides options for businesses and individuals who may rely on older equipment. However, it's essential that these containers are regularly inspected and maintained to ensure they remain safe and compliant with more modern safety standards.

Other responses, such as discarding, reinforcing, or retrofitting, imply that these containers cannot be used as-is or require significant modifications. The acceptance of older containers directly underlines the recognition of appropriately maintained equipment and the importance of safety regulations that evolve over time while still allowing for legacy systems to function.
