PHYSICAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Explosives Classification not possible - - - - It contains chemical groups (acetylene) associated with explosive properties. However, since it is not used as explosives, no evaluation was carried out on this substance as explosives. Consequently, it was classified into the "Classification not possible" category.
2 Flammable gases (including chemically unstable gases) Not applicable - - - - Liquid (GHS definition)
3 Aerosols Not applicable - - - - Not aerosol products.
4 Oxidizing gases Not applicable - - - - Liquid (GHS definition)
5 Gases under pressure Not applicable - - - - Liquid (GHS definition)
6 Flammable liquids Category 2 Danger H225: Highly flammable liquid and vapour P303+P361+P353: IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower.
P370+P378: In case of fire: Use ... for extinction.
P403+P235: Store in a well-ventilated place. Keep cool.
P210: Keep away from heat/sparks/open flames/hot surfaces. ? No smoking.
P233: Keep container tightly closed.
P240: Ground/bond container and receiving equipment.
P241: Use explosion-proof electrical/ventilating/lighting/.../equipment.
P242: Use only non-sparking tools.
P243: Take precautionary measures against static discharge.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P501: Dispose of contents/container to ...
The flash point of the pure substance is 10degC (HSDB (2006)) and its initial boiling point is 89degC (boiling point) (NFPA (12th, 1997)). Based on this information, the substance was classified into Category 2. (Since 80% toluene solution is rated as Class 3, packing group II (UN 2345) by the UNRTDG, it was classified into Category 2.)
7 Flammable solids Not applicable - - - - Liquid (GHS definition)
8 Self-reactive substances and mixtures Classification not possible - - - - It contains chemical groups (acetylene) associated with explosive properties. According to the IMDGC and UN 2345, the pure product is shock-sensitive and decomposes with explosive violence and possibility of detonation when heated under confinement. It can be ignited by impact. Based on this report, the pure product is presumably self-reactive. However, since no further information is available, the substance was classified into the "Classification not possible" category. (80% toluene solution, which is transported, is rated as Class 3 II, indicating that it is non-hazardous in terms of self-reactivity and defined as Type G.)
9 Pyrophoric liquids Not classified - - - - Since its autoignition point is 324degC (NFPA (12th, 1998)), we determined that the substance does not spontaneously ignite in contact with air at room temperature and classified it into the "Not classified" category.
10 Pyrophoric solids Not applicable - - - - Liquid (GHS definition)
11 Self-heating substances and mixtures Classification not possible - - - - No data available.
12 Substances and mixtures which, in contact with water, emit flammable gases Not applicable - - - - The chemical structure of the substance does not contain metals or metalloids (B, Si, Ge, As, Se, Sn, Sb, Te, Bi, Po, At).
13 Oxidizing liquids Not applicable - - - - The substance does not contain oxygen, fluorine or chlorine.
14 Oxidizing solids Not applicable - - - - Liquid (GHS definition)
15 Organic peroxides Not applicable - - - - Containing no bivalent -O-O- structure in the molecule
16 Corrosive to metals Classification not possible - - - - Classification not possible due to lack of data.
