Rationale for the classification | |
---|---|---|---|---|---|---|
1 | Explosives | Not classified | - | - | - | It contains a chemical group associated with explosive properties (O-halogen), but it does not correspond to superior explosives due to class 5.1 subsidiary risk 6.1 in UNRTDG (UN1447). |
2 | Flammable gases (including chemically unstable gases) | Not applicable | - | - | - | "Solids" according to GHS definition. |
3 | Aerosols | Not applicable | - | - | - | Not an aerosol product. |
4 | Oxidizing gases | Not applicable | - | - | - | "Solids" according to GHS definition. |
5 | Gases under pressure | Not applicable | - | - | - | "Solids" according to GHS definition. |
6 | Flammable liquids | Not applicable | - | - | - | "Solids" according to GHS definition. |
7 | Flammable solids | Not classified | - | - | - | It was classified as "Not classified" from information that it is non-flammable (Hommel (1996)). |
8 | Self-reactive substances and mixtures | Not applicable | - | - | - | It was classified as an oxidizing substance. |
9 | Pyrophoric liquids | Not applicable | - | - | - | "Solids" according to GHS definition. |
10 | Pyrophoric solids | Not classified | - | - | - | There is information that it is non-flammable (Hommel (1996)). |
11 | Self-heating substances and mixtures | Not classified | - | - | - | There is information that it is non-flammable (Hommel (1996)). |
12 | Substances and mixtures which, in contact with water, emit flammable gases | Not classified | - | - | - | It contains a metal (Ba), but it is judged to be stable in the water from water solubility data of 312g/100 g at 20 degrees C (CRC (91st, 2010)). |
13 | Oxidizing liquids | Not applicable | - | - | - | "Solids" according to GHS definition. |
14 | Oxidizing solids | Category 2 |
H272 |
P370+P378 P210 P220 P221 P280 P501 |
Due to an oxidizer (Sax (11th, 2004)) and class 5.1 PGII in UNRTDG (UN1447), it was classified in Category 2. | |
15 | Organic peroxides | Not applicable | - | - | - | It is an inorganic compound. |
16 | Corrosive to metals | Classification not possible | - | - | - | No established test method suitable for solid substances. |

Rationale for the classification | |
---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Classification not possible | - | - | - |
No data. Besides, it is classified in Xn; R20/22 in EU classification (EC-JRC (ESIS) (Access on July. 2011)). |
1 | Acute toxicity (Dermal) | Classification not possible | - | - | - | No data. |
1 | Acute toxicity (Inhalation: Gases) | Not applicable | - | - | - | "Solids" according to GHS definition. |
1 | Acute toxicity (Inhalation: Vapours) | Classification not possible | - | - | - | No data. |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible | - | - | - |
No data. Besides, it is classified in Xn; R20/22 in EU classification (EC-JRC (ESIS) (Access on July. 2011)). |
2 | Skin corrosion/irritation | Category 2 |
H315 |
P302+P352 P332+P313 P264 P280 P321 P362 |
There are no data on this substance. However, on the basis of multiple descriptions of barium or barium compounds which show irritation to skin such as barium chlorate as an analog substance causes irritation to skin (HSDB (2002)), barium and soluble barium compounds have skin irritation (ACGIH (2001)), and barium causes mild skin irritation to rabbits (EHC107 (1990)), it was classified in Category 2. |
|
3 | Serious eye damage/eye irritation | Category 2A |
H319 |
P305+P351+P338 P337+P313 P264 P280 |
There are no data on this substance. However, on the basis of multiple descriptions of barium or barium compounds which show irritation to eyes such as barium chlorate as an analog substance causes irritation to eyes (HSDB (2002)), barium and soluble barium compounds have eye irritation (ACGIH (2001)), and barium causes severe eye irritation to rabbits (EHC107 (1990)), it was classified in Category 2A. |
|
4 | Respiratory sensitization | Classification not possible | - | - | - | No data. |
4 | Skin sensitization | Classification not possible | - | - | - | No data. |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | No data. |
6 | Carcinogenicity | Classification not possible | - | - | - |
No data. Besides, barium and soluble barium are classified in A4 in ACGIH (ACGIH (2001)). |
7 | Reproductive toxicity | Classification not possible | - | - | - | No data. |
8 | Specific target organ toxicity - Single exposure | Category 1 (muscle, heart, digestive system), Category 3 (respiratory tract irritation) |
H370 H335 |
P307+P311 P260 P264 P270 P321 P405 P501 P304+P340 P403+P233 P261 P271 P312 |
There are no data on this substance. But there is the information that barium ion is a muscle poison and the poisoning cases caused by barium compounds show gastrointestinal injuries followed by adverse myocardial stimulation (ACGIH (2001)). Furthermore, acute gastroenteritis and muscular paralysis caused by loss of deep reflexes are reported (EHC107 (1990)). Therefore, it was classified in Category 1 (muscle, heart, digestive system). Besides, salivation, nausea, diarrhoea, tachycardia, hypokalemia, twitching, flaccid paralysis of skeletal muscle, respiratory muscle paralysis, and ventricular fibrillation were reported as acute effects after oral administration in rats (EHC107 (1990)). Furthermore, there is the information that inhalation of barium chlorate as an analog substance causes irritation to a respiratory tract (HSDB (2002)), therefore, it was classified in Category 3 (respiratory tract irritation). |

9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | No data. |
10 | Aspiration hazard | Classification not possible | - | - | - | No data. |
