In ERG 2024, Guide 157 is titled “Substances - Toxic and/or Corrosive (Non-Combustible/Water-Sensitive)”.
Guide 157 covers 58 UN/NA numbers and 74 material names in ERG 2024. None of them carries the letter P (157P). 11 are highlighted in green and listed in Table 1: UN/NA 1560 (Arsenic chloride); UN/NA 1670 (Perchloromethyl mercaptan); UN/NA 1680 (Potassium cyanide, solid); UN/NA 1689 (Sodium cyanide, solid); UN/NA 1732 (Antimony pentafluoride); UN/NA 1818 (Silicon tetrachloride); UN/NA 2032 (Nitric acid, red fuming); UN/NA 2308 (Nitrosylsulfuric acid, liquid); UN/NA 2692 (Boron tribromide); UN/NA 3048 (Aluminum phosphide pesticide) and UN/NA 3456 (Nitrosylsulfuric acid, solid). 8 appear in Table 2 as water-reactive materials that produce toxic gases: UN/NA 1680 (Potassium cyanide, solid: HCN); UN/NA 1689 (Sodium cyanide, solid: HCN); UN/NA 1732 (Antimony pentafluoride: HF); UN/NA 1818 (Silicon tetrachloride: HCl); UN/NA 2308 (Nitrosylsulfuric acid, liquid: NO2); UN/NA 2692 (Boron tribromide: HBr); UN/NA 3048 (Aluminum phosphide pesticide: PH3) and UN/NA 3456 (Nitrosylsulfuric acid, solid: NO2).
The Spanish edition (GRE 2024) titles this guide “Sustancias - Tóxicas y/o Corrosivas (no combustibles / susceptibles al agua)”, and the French edition (GMU 2024) “Substances - Toxiques et/ou Corrosives (non-combustibles/sensibles à l’eau)”.
