In ADR 2015 Table A, UN3135 WATER-REACTIVE SOLID, FLAMMABLE, N.O.S. at Packing Group I level shows neither a UN portable tank code (in column 10), nor an ADR tank code (in column 12), and thus cannot be carried in tanks.
Yet in column 15 the tunnel restriction code is shown as “(B/E)”. According to ADR Chapter 8.6 the “B” would be applicable only to carriage in tanks, yet this mode of carriage is not allowed. Why then show as “(B/E)” rather than “(E)”?
