Safety Advisory: Certified IM 101 and IM 102 Steel Portable Tanks With Bottom Outlets Without Internal Discharge Valves or Shear Sections

Safety advisory notice; correction.

RSPA published a safety advisory notice in the Federal Register (62 FR 37638) under notice 97-6 on July 14, 1997. The words ``capable of being closed from a location'' were inadvertently omitted in the advisory notice for material quoted from 49 CFR 173.32c(g)(2). This document corrects this error and, for the convenience of readers, reprints the text of the July 14, 1997 notice in its entirety, as follows: This is to notify owners and users of DOT specification IM 101 and IM 102 portable tanks with filling or discharge connections below the normal liquid level that these tanks may be used for shipping hazardous materials only if they have internal discharge valves and shear sections. Internal discharge valves and shear sections are safety devices required on the bottom-outlets of IM portable tanks in hazardous material service to prevent significant release of lading when damage is sustained at the filling/discharge connection. Without those safety features, damage to a bottom outlet is far more likely to result in loss of a tank's entire lading.
