Lookup Portable Tank Instructions

For example, the tank instruction for HYPOCHLORITE SOLUTION (UN Number 1791, Packing group II) is T7, with provision numbers TP2 and TP24. Turning to the portable tank instructions, we find T7 listed in the summary table under 4.2.5.2.6. This table shows the minimum test pressure and tank shell thickness, as well as the pressure release and bottom opening provisions. Note that in subsequent tables, some dangerous goods are given specific tank instructions based on their UN number under portable tank instructions T23 and T50. Portable tank special provisions are listed under 4.2.5.3. The provision numbers TP2 and TP24 for HYPOCHLORITE SOLUTION add more detailed information about the degree of filling and a method of avoiding pressure build-up in the tank. A final section of the Chapter (4.2.6) gives provisions for the transport of road tank vehicles.
