Division 4.1: Flammable Solid . Flammable solids are any of the following four types of materials: Desensitized Explosives: explosives that, when dry, are Explosives of Class 1 other than those of compatibility group A, which are wetted with sufficient water, alcohol, or plasticizer to suppress explosive properties; and are specifically authorized by name either in the 49CFR 172.101 Table or ...
Nitroguanidine - sometimes abbreviated NGu - is a colorless, crystalline solid that melts at 257 °C and decomposes at 254 °C. Nitroguanidine is an extremely insensitive but powerful high explosive. Wetting it with > 20 wt.-% water effects desensitization from HD 1.1 down to HD 4.1 (flammable solid). [2]
2.2 Non-Flammable Gases: Gases which are neither flammable nor poisonous. Includes the cryogenic gases/liquids (temperatures of below -100 °C) used for cryopreservation and rocket fuels, such as nitrogen , neon , and carbon dioxide .
Solid Any material which, in either concentration tested, exhibits a mean burning time less than or equal to the mean burning time of a 3:7 potassium bromate/cellulose mixture and the criteria for Packing Group I and II are not met. Group I 5.1: Liquid Any material which spontaneously ignites when mixed with cellulose in a 1:1 ratio; or
Extremely flammable gas H221: Flammable gas H222: Extremely flammable material H223: Flammable material H224: Extremely flammable liquid and vapour H225: Highly flammable liquid and vapour H226: Flammable liquid and vapour H227: Combustible liquid H228: Flammable solid H229: Pressurized container: may burst if heated H230
Flammable gases – Gases which at 20 °C and a standard pressure of 101.3 kPa: are ignitable when in a mixture of 13 percent or less by volume with air; or; have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit. Alternative sign. Division 2.1 Non-flammable non-toxic gases – Gases which:
For international shipments the label must say Toxic if it will be worded. PG III (Packing Group III): May be used instead of POISON placard on 454 kg (1001 lb) or more gross weight of Poison PG III materials (see Assignment of packing groups and hazard zones below).
Substances and mixtures which, in contact with water, emit flammable gases are categorized from 1 to 3 based on the ignitability of the gas emitted. Oxidizing liquids contribute to the combustion of other materials and are categorized from 1 to 3 in decreasing oxidizing potential. Oxidizing solids follow the same criteria as oxidizing liquids.
