Action
Safety advisory notice.
Summary
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 bottom-outlet IM 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.
