| 
Explosive substances, which can cause a fire with an explosive action. Pyrotechnic substances and articles | 1.1 | Explosives and pyrotechnic substances and articles , which explode on a mass scale – explosion covers the entire load; | 
| 1.2 | Explosives and pyrotechnic substances and products with no mass explosion hazard ; | 
| 1.3 | Explosives and pyrotechnic substances and articles that can flame out without explosives or with a minor blasting out; | 
| 1.4 | Explosives and pyrotechnic substances and products with a minor blast hazard – only in case of ignition or initiation. The explosion does not destroy the packing and devices; | 
| 1.5 | Explosive substances that can explode on a mass scale; initiation or transition from burning to explosion while transporting is highly improbable; | 
| 1.6 | Detonation-insensitive articles which do not explode on a mass scale; minor possibility of explosion hazard. | 
| 
Gases – compressed, lysed under pressure and liquefied by cooling | 2.1 | Non-flammable gases; |

| TFC | toxic , flammable , corrosive; | 
| TOC | toxic , oxidizing , corrosive; | 
| 
Flammable and combustible liquids, mixtures of liquids. Liquids containing solids in solution. Suspensions that exhale.   | 3.1 | flammable liquids that have a low explosion temperature or liquids with an explosion temperature – 18°C in a closed crucible; | 
| 3.2 | flammable liquids with a mean explosion temperature – from – 18°C to + 23°C in a closed crucible; |

| 4.2 | flammable substances, that can spontaneous heat and ignite; | 
| 4.3 | substances that emit flammable gases in case of water contamination; | 
| 
Organic peroxides, oxidizing substances, easily emit oxygen and sustain combustion.   | 5.1 | Non-combustible oxidizing substances, conduce combustibility of other substances. During combustion they emit oxygen; | 
| 5.2 | flammable organic peroxides are generally combustible, can oxidize other substances and dangerously interact with them; | 
| a | strongly conduce combustion; | 
| b | conduce combustion; | 
| c | insignificantly conduce combustion. | 
| 
Toxic and infectious substances. Can cause a toxication, a disease or death. | 6.1 | toxic substances that cause toxication by inhalation, contacting with skin and if swallowed; | 
| 6.2 | substances containing pathogenic germs; |
