provisions] specifies codes for stowage requirements for specific hazardous materials. The<br />

meaning <strong>of</strong> each code in Column (10B) is set forth in § 176.84 <strong>of</strong> this subchapter.<br />

Vessel shipments <strong>of</strong> Class 1 explosives are currently required to be stored away<br />

from all sources <strong>of</strong> heat including steam pipes, heating coils, sparks, and flame in<br />

accordance with § 176.116(a). In addition to this general provision in § 176.116, several<br />

vessel stowage codes in column (10B) make reference to shading or stowing away from<br />

heat. To harmonize with the IMDG <strong>Code</strong>, reduce the number <strong>of</strong> redundant vessel stowage<br />

codes, and incorporate the addition <strong>of</strong> a new definition for protected from sources <strong>of</strong> heat<br />

(see Section 176.2 <strong>of</strong> this final rule for definition) <strong>PHMSA</strong> is deleting vessel stowage<br />

codes 50 and 48 and replacing all references to these codes with stowage code 25. See<br />

Section 176.84 for a detailed discussion <strong>of</strong> our revision to stowage code 25.<br />

The following proper shipping names and corresponding identification numbers<br />

will have stowage code 48 replaced with stowage code 25 in Column (10B) in the HMT. If<br />

the commodity is currently assigned both stowage code 48 and 25 in Column (10B) in the<br />

HMT stowage code 48 will be deleted and stowage code 25 will remain.<br />
