Its rat LD50 through dermal administration is 12 mg/kg (Patty 5th, 2001). Based on this report, the substance was classified into Category 1. |
| 1 | Acute toxicity （Inhalation: Gases） | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 1 | Acute toxicity （Inhalation: Vapours） | Category 1 |
|
Danger | H330: Fatal if inhaled |
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. P260: Do not breathe dust/fume/gas/mist/vapours/spray. P271: Use only outdoors or in a well-ventilated area. P284: Wear respiratory protection.

Its mouse LC50 through 30-minute inhalation exposure is 1500 mg/m3 (Patty 5th, 2001). The 30-minute LC50 value was converted to 4-hour LC50 value using the following equation: LC50 (4 hours) = 1500*sqrt (0.5) / sqrt (4) = 530 mg/m3. Moreover, with the use of the conversion factor: 1 mg/m3 = 0.1567 ppm (at 25degC), LC50 (4 hours) = 83.1 ppm. Its saturated vapour pressure at 25degC = 65.1 mmHG*133.3 = 8677.8 Pa = 8.677 kPa and its saturated vapour pressure concentration (25degC) = 85,911 ppm. Because the LC50 value, 83.1 ppm, is lower than 90% of the saturated vapour pressure concentration, the experiment was conducted presumably in a vapour with almost no included mists. Thus, using ppm-based concentration criteria, the substance was classified into Category 1. |
| 1 | Acute toxicity （Inhalation: Dusts and mists） | Classification not possible | - | - | - | - | No data available. |
| 2 | Skin corrosion/irritation | Category 1A-1C |
|
Danger | H314: Causes severe skin burns and eye damage |
P301+P330+P331: IF SWALLOWED: Rinse mouth. Do NOT induce vomiting. P303+P361+P353: IF ON SKIN （or hair）: Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. P260: Do not breathe dust/fume/gas/mist/vapours/spray. P264: Wash ... thoroughly after handling. P280: Wear protective gloves/protective clothing/eye protection/face protection. P310: Immediately call a POISON CENTER or doctor/physician. P321: Specific treatment （see ... on this label）. P363: Wash contaminated clothing before reuse. P405: Store locked up. P501: Dispose of contents/container to ... |
It brings about a strong vesicant action on the skin and is corrosive (Patty 5th, 2001). As refined categorization is difficult, we determined that the substance is classified between Category 1A and 1C. |
| 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. |
Since it damages the deeper ocular structures (Patty 5th, 2001), we determined the substance to be corrosive and classified it into Category 1. |
| 4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data available. |
| 4 | Skin sensitization | Classification not possible | - | - | - | - | Classification not possible due to lack of data. |
| 5 | Germ cell mutagenicity | Category 1B |
|
Danger | H340: May cause genetic defects |
P308+P313: IF exposed or concerned: Get medical advice/attention. P201: Obtain special instructions before use. P202: Do not handle until all safety precautions have been read and understood. P281: Use personal protective equipment as required. P405: Store locked up. P501: Dispose of contents/container to ... |
According to IARC 9 (1975) and S7 (1987), it induces dominant lethal mutations in mice and micronuclei in bone-marrow cells of mice. Thus, the substance was classified into Category 1B. |
| 6 | Carcinogenicity | Category 1B |
|
Danger | H350: May cause cancer |
P308+P313: IF exposed or concerned: Get medical advice/attention. P201: Obtain special instructions before use. P202: Do not handle until all safety precautions have been read and understood. P281: Use personal protective equipment as required. P405: Store locked up. P501: Dispose of contents/container to ... |
According to IARC S7 (1987), this substance is rated as Group 2A. Hence, it was classified into Category 1B. |
| 7 | Reproductive toxicity | Classification not possible | - | - | - | - | Classification not possible due to lack of data. As additional background information, IARC 9 (1975) documented that intravenous injection of this substance to pregnant rats on the 4th day of pregnancy resulted in signs of fetal toxicity being observed. However, since the administration route used in this study is not a conventional route and concentrations of the substance administered are not mentioned. As such, the report was not considered for classification. |
| 8 | Specific target organ toxicity - Single exposure | Category 2 (blood system, respiratory system) |
|
Warning | H371: May cause damage to organs (blood system, respiratory system) |
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 ... |
Evaluating the following descriptions comprehensively, the substance was classified into Category 2 (blood system and respiratory system): people who made a contact with this substance developed bone marrow degeneration within 12 hours, which progressed to severe aplasia. These people also experienced a moderate anemia accompanied with lymphopenia, granulocytopenia, and thrombocytopenia (HSDB, 2004); this substance causes respiratory tract injury (HSDB, 2004); inhaling nitrogen mustard can irritate the nose and throat (HSFS, 1998); and this substance may be corrosive to the skin and eyes (Patty 5th, 2001). |
