Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
1 | Explosives | Classification not possible | - | - | - | - | It contains chemical groups (chlorates) associated with explosive properties. The aqueous solution, which is of higher than 10% concentration, is prohibited from being transported (Ship Safety Act / Article 5-3(d) of Public Notice of the Ministry of Transport, No.549 of 1979). 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 |
3 | Aerosols | Not applicable | - | - | - | - | Not aerosol products. |
4 | Oxidizing gases | Not applicable | - | - | - | - | Liquid |
5 | Gases under pressure | Not applicable | - | - | - | - | Liquid |
6 | Flammable liquids | Classification not possible | - | - | - | - | Although it is generally considered as a nonflammable aqueous solution, the substance was classified into the "Classification not possible" category due to insufficient data available. |
7 | Flammable solids | Not applicable | - | - | - | - | Liquid |
8 | Self-reactive substances and mixtures | Not applicable | - | - | - | - | It contains chemical groups (Chlorates) associated with explosive properties. The aqueous solution, which is of higher than 10% concentration, is prohibited from being transported (Ship Safety Act / Article 5-3(d) of Public Notice of the Ministry of Transport, No.549 of 1979). However, since it is defined as an oxidizing liquid, it does not fit the definition of self-reactive substances. Consequently, the substance was classified into the "Not applicable" category. |
9 | Pyrophoric liquids | Classification not possible | - | - | - | - | Although it is generally considered as a nonflammable aqueous solution, the substance was classified into the "Classification not possible" category due to insufficient data available. |
10 | Pyrophoric solids | Not applicable | - | - | - | - | Liquid |
11 | Self-heating substances and mixtures | Classification not possible | - | - | - | - | Although it is generally considered as a nonflammable aqueous solution, the substance was classified into the "Classification not possible" category due to insufficient 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 | Category 1-2 | Danger | H271: May cause fire or explosion; strong oxidizer |
P371+P380+P375: In case of major fire and large quantities: Evacuate area. Fight fire remotely due to the risk of explosion. P306+P360: IF ON CLOTHING: Rinse immediately contaminated clothing and skin with plenty of water before removing clothes. P370+P378: In case of fire: Use ... for extinction. P210: Keep away from heat/sparks/open flames/hot surfaces. ? No smoking. P220: Keep/Store away from clothing/.../combustible materials. P221: Take any precaution to avoid mixing with combustibles/... P280: Wear protective gloves/protective clothing/eye protection/face protection. P283: Wear fire/flame resistant/retardant clothing. P501: Dispose of contents/container to ... |
If the aqueous solution is of 10% concentration or less by mass, it is defined as UN2626, Division 5.1 II. The aqueous solutions which are of higher than 10% concentration are prohibited from being transported and no packing group is assigned. While its classification for oxidizing ability is likely Category 1, we chose more liberal classification of Category 1-2. | |
14 | Oxidizing solids | Not applicable | - | - | - | - | Liquid |
15 | Organic peroxides | Not applicable | - | - | - | - | Inorganic substance |
16 | Corrosive to metals | Category 1 | Warning | H290: May be corrosive to metals |
P234: Keep only in original container. P390: Absorb spillage to prevent material-damage. P406: Store in corrosive resistant/... container with a resistant inner liner. |
Based on the document that many metals release hydrogen while being dissolved in chloric acid to produce chlorate (Encyclopedia Chimica, Kyoritsu Shuppan Co. Ltd.), the substance was classified into Category 1. |

2 | Skin corrosion/irritation | Classification not possible | - | - | - | - | It is reported that coming into contact with the substance can irritate and burn human skin and eyes (HSFS (2002)). However, since no other information is available, the substance was classified into the "Classification not possible" category. |
3 | Serious eye damage/eye irritation | Classification not possible | - | - | - | - | It is reported that coming into contact with the substance can irritate and burn human skin and eyes (HSFS (2002)). However, since no other information is available, the substance was classified into the "Classification not possible" category. |
