PHYSICAL HAZARDS

Hazard class Classification Symbol
Signal word
Hazard statement Precautionary statement Rationale for the classification
1 Explosives Classification not possible - - - The substance contains a chemical group associated with an explosive property (neighboring oxygen atoms) and it is classified in Class 5.2 and subsidiary risk 1 in UNRTDG (UN3102 (ORGANIC PEROXIDE TYPE B, SOLID, concentration > 82 %)), but the classification is not possible due to no test data for sub-categorization.
2 Flammable gases (including chemically unstable gases) Not applicable - - - It is a solid at normal temperatures (UNRTDG (16th, 2009)).
3 Aerosols Not applicable - - - Not an aerosol product.
4 Oxidizing gases Not applicable - - - It is a solid at normal temperatures (UNRTDG (16th, 2009)).
5 Gases under pressure Not applicable - - - It is a solid at normal temperatures (UNRTDG (16th, 2009)).
6 Flammable liquids Not applicable - - - It is a solid at normal temperatures (UNRTDG (16th, 2009)).
7 Flammable solids Classification not possible - - - No data.
8 Self-reactive substances and mixtures Not applicable - - - It was classified as "Not applicable" because it is classified as "Organic peroxides."
9 Pyrophoric liquids Not applicable - - - It is a solid at normal temperatures (UNRTDG (16th, 2009)).
10 Pyrophoric solids Not classified - - - It is conceivable that it does not to ignite at normal temperatures from an ignition point of 497 degrees C (NOF CORPORATION (Access on July. 2011)).
11 Self-heating substances and mixtures Classification not possible - - - No data.
12 Substances and mixtures which, in contact with water, emit flammable gases Not applicable - - - Not containing metals or semimetals (B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At).
13 Oxidizing liquids Not applicable - - - It is a solid at normal temperatures (UNRTDG (16th, 2009)).
14 Oxidizing solids Classification not possible - - - It is an organic compound containing oxygen, but the classification is not possible due to no data.
15 Organic peroxides Type B
