Special provisions (§172.102)
A7 — Steel packagings must be corrosion-resistant or have protection against corrosion.
B15 — Packagings must be protected with non-metallic linings impervious to the lading or have a suitable corrosion allowance.
B23 — Tanks must be made of steel that is rubber lined or unlined. Unlined tanks must be passivated before being placed in service. If unlined tanks are washed out with water, they must be repassivated prior to return to service. Lading in unlined tanks must be inhibited so that the corrosive effect on steel is not greater than that of hydrofluoric acid of 65 percent concentration.
N5 — Glass materials of construction are not authorized for any part of a packaging which is normally in contact with the hazardous material.
N34 — Aluminum construction materials are not authorized for any part of a packaging which is normally in contact with the hazardous material.
