Statistical calculations was applied based on LC50 on rats: 0.899, 0.899, 1.92, and 1.36mg/L (SIDS 2002). It was classified as Category 2 based on calculated value of 0.899mg/L (equivalent to 328 ppm).
1 Acute toxicity (Inhalation: Dusts and mists) Not classified - - - - No data available
2 Skin corrosion/irritation Category 3 - Warning H316: Causes mild skin irritation P332+P313: If skin irritation occurs: Get medical advice/attention. Based on the descriptions that there was mild skin irritation in Draize test on rabbits (SIDS, 2002) and it may cause dermatitis by repetitive or long-term skin contacts on humans, (MOE Risk Assessment the 3rd volume, 2004), it was judged to have mild irritativeness and was classified as Category 3.

Mild irritation was indicated to eye of rabbit. But it recovered within 1 hour (ACGIH 7th.2001). So it was set as Category 2B.
4 Respiratory sensitization Classification not possible - - - - No data
4 Skin sensitization Classification not possible - - - - Although no skin sensitization is assumed to be found in guinea pigs (PATTY 4th.1994), this is uncategorizable because there is no data that clearly negate skin sensitization.
5 Germ cell mutagenicity Not classified - - - - The substance was regarded as outside the categories based on the fact that it was negative in vivo micronucleus tests using both rat and mouse bone-marrow cells and mouse peripheral erythrocytes (SIDS 2002, NTP DB 2005, NTP TR 497, 2001).
6 Carcinogenicity Classification not possible - - - - Carcinogenicity is not observed in a study using rats and mice in which repetitive oral administration was performed for two years (NTP TR 497, 2001, MOE Risk Assessment SIDS, 2002, the 3rd volume, 2004). But data is insufficient, it cannot be classified.

Since the significant low sperm count of F1-generation male in two generation reproduction study, or the delay of estrous cycle of male after the last administration for 13 weeks (all are done by oral administration to rat, SIDS 2002, NTP DB 2005, MOE Risk Assessment the third volume 2004, NTP TR 497 2001), and the decrease of the male rate of offspring per litter in teratogenicity test (rabbit oral administration. SIDS 2002, CERI Hazard Data, 2001), the decrease of weight of fetus (rat inhalation exposure. SIDS 2002, CERI Hazard Data 2001, and NTP TR 497 2001) was observed, it is classified into the Category 1B.

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.
P321: Specific treatment (see ... on this label).
P405: Store locked up.
P501: Dispose of contents/container to ...
When it administers orally to rat in the range of guidance value of Category 1 (less than 300mg/kg), the symptom of central nervous systems, such ataxia, tremor, clonic convulsion, and hygrostomia, were observed (NTP TR 497 2001, the Ministry of Health, Labour and Welfare report 2005, SIDS 2002, ACGIH 7th. 2001), the same symptom was also observed in the aerial density about 1-2mg/L by inhalation to rat. So it was classfied into Category 1 (central nervous system).
9 Specific target organ toxicity - Repeated exposure Category 1 (blood, central nervous system, sensory organ) Danger H372: Cause damage to organs through prolonged or repeated exposure (blood, central nervous system, sensory organ) 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.
P314: Get medical advice/attention if you feel unwell.
P501: Dispose of contents/container to ...
Due to repeated oral administrations to rats, some conditions, such as anemia, clonic convulsion, tremors, salivation, and ataxia, and histologic changes of the olfactory epithelium were observed in dosage within Category 1 (MHLW reports 2005, SIDS 2002, the 3rd volume of MOE Risk Assessment 2004, NTP DB 2005 and NTP TR 497 2001), the target organs were judged to be blood, the central nervous system, and the sense organ. When it makes dogs inhale, the symptoms of these central nervous systems was observed, and a histologic changes of brain was also observed (SIDS 2002 and ACGIH 7th.2001 and IRIS 2005, MOE Risk Assessment the 3rd volume 2004).
10 Aspiration hazard Classification not possible - - - - No data available
