|Publication Date:||1 January 2013|
Cylinders and tubes for which procedures apply
The cleaning recommendations contained in this publication are intended for cylinders of water capacities from 0.5 L to 454 L and tubes up to 3000 L that are fabricated in accordance with specifications promulgated by the U.S. Department of Transportation (DOT) in the United States and the Canadian Transport Commission (CTC) or Transport Canada (TC) in Canada and are authorized for reuse [1, 2, 3, 4].1 Unless otherwise specified, when the word "cylinder" is used in this publication, it applies to both cylinders and tubes.
The references made in this publication, in general, apply equally to DOT specifications and regulations in the United States and TC specifications and regulations in Canada [1, 2, 3, 4].
In the United States new cylinders are prefaced by "DOT" and in Canada new cylinder specifications are prefaced by "TC". Older U.S. cylinders are prefaced by "ICC" and older Canadian cylinders are prefaced by "CTC". Cylinders marked "CTC/DOT" or "TC/DOT" are authorized for service in both the United States and Canada. These procedures also apply to these older cylinder specifications.
These recommendations do not apply to:
- nonrefillable and composite cylinders;
- cylinders with internal linings, plating, or treatments;
- cylinders being changed into medical and food gas service; and
- cargo tanks, portable tanks, and tank cars.
These containers may require special techniques that can best be prescribed by the container manufacturer. These containers may have other requirements set forth by additional government agencies, such as DOT, Food and Drug Administration (FDA), TC, and Canadian Health Products and Food Branch Inspectorate (HPFBI).
