|---|---|---|---|---|---|---|---|
| 1 | Acute toxicity （Oral） | Category 4 |
|
Warning | H302: Harmful if swallowed |
P301+P312: IF SWALLOWED: Call a POISON CENTER or doctor/physician if you feel unwell. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P330: Rinse mouth. P501: Dispose of contents/container to ... |
Based on the rat LD50 (oral route) value of 308mg/kg (RTECS (2006)). |
| 1 | Acute toxicity （Dermal） | Classification not possible | - | - | - | - | No data available |
| 1 | Acute toxicity （Inhalation: Gases） | Not applicable | - | - | - | - | Due to the fact that the substance is "solid" according to the GHS definition and inhalation of its gas is not expected. |
| 1 | Acute toxicity （Inhalation: Vapours） | Classification not possible | - | - | - | - | No data available |
| 1 | Acute toxicity （Inhalation: Dusts and mists） | Classification not possible | - | - | - | - | No data available |
| 2 | Skin corrosion/irritation | Category 1 |
|
Danger | H314: Causes severe skin burns and eye damage |

Based on the evidence of "severe irritation" from skin irritation tests in rats and rabbits (exposure duration unknown). Also based on the description in the report on epidemiological studies of human exposure (CERI Hazard Data 2001-56 (2002)): "soluble barium compounds cause irritation of the eye, skin, nose, throat and bronchi. In particular, aqueous solutions of barium hydroxide are strongly alkaline and severely irritate the eye and skin." Also based on the description in CICAD (2001) (exposure duration unknown): "Barium hydroxide is strongly alkaline and therefore corrosive." |
| 3 | Serious eye damage/eye irritation | Category 1 |
|
Danger | H318: Causes serious eye damage |
P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P280: Wear protective gloves/protective clothing/eye protection/face protection. P310: Immediately call a POISON CENTER or doctor/physician. |
Based on the evidence of "severe irritation" from rabbit eye irritation tests (IUCLID (2000)). Also based on the description in the report on epidemiological studies of human exposure (CERI Hazard Data 2001-56 (2002)): "soluble barium compounds cause irritation of the eye, skin, nose, throat and bronchi. In particular, aqueous solutions of barium hydroxide are strongly alkaline and severely irritate the eye and skin." Also based on the description in CICAD 33 (2001): "corrosive." |

|
Warning |
H371: May cause damage to organs (nervous system, muscle) H335: May cause respiratory irritation (respiratory tract irritation) |
P309+P311: IF exposed or if you feel unwell: Call a POISON CENTER or doctor/physician. P260: Do not breathe dust/fume/gas/mist/vapours/spray. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P405: Store locked up. P501: Dispose of contents/container to ... P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. P403+P233: Store in a well-ventilated place. Keep container tightly closed. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P271: Use only outdoors or in a well-ventilated area. P312: Call a POISON CENTER or doctor/physician if you feel unwell. |
Based on the human evidence: "Barium hydroxide and barium oxide irritate the eye, skin, and respiratory tract" (CICAD 33 (2001). Also based on the evidence from animal studies: "treated animals relaxed and subsequently suffered vomiting and diarrhea; exhibited smooth muscle contraction which occurs during ejaculation; paralysis and spasm in the hind limbs were observed in some rats" (IUCLID (2000)). The effects on experimental animals were observed at dosing levels within the guidance value ranges for Category 2. |
