In ERG 2024, Guide 138 is titled “Substances - Water-Reactive (Emitting Flammable Gases)”.
Guide 138 covers 74 UN/NA numbers and 94 material names in ERG 2024. None of them carries the letter P (138P). None is highlighted in green, so none of them has an entry in Table 1. 2 numbers also have names under other guides: UN/NA 3171 (Guides 154 and 147) and UN/NA 3536 (Guide 147).
The Spanish edition (GRE 2024) titles this guide “Sustancias - Reactivas con el Agua (emiten gases inflamables)”, and the French edition (GMU 2024) “Substances - Réagissant à l’eau (émettant des gaz inflammables)”.
