Based on rat LC50 value (4 hours): 6ppm (equivalent: 0.01548mg/L) (ACGIH 7th, 2001), it was classified as Category 1.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - - No data available
2 Skin corrosion/irritation Category 2 Warning H315: Causes skin irritation P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P332+P313: If skin irritation occurs: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment (see ... on this label).
P362: Take off contaminated clothing and wash before reuse.
There was no animal examination data. But it was set as Category 2 from the description "strong stimulativeness and a burn may be caused by skin contacts" (HSFS (2000)).
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.
We classified it as Category 1 based on description that "it stimulated the eyes"(HSDB (2005)), and on the description that "it had a severe irritant property accompanied by the eye injuries when touched to the eye"(HSFS (2000)).

Warning
H370: Causes damage to organs (central nervous system)
H336: May cause drowsiness or dizziness (narcotic effects, respiratory tract irritation)
H335: May cause respiratory irritation (narcotic effects, respiratory tract irritation)
P307+P311: IF exposed: Call a POISON CENTER or doctor/physician.
P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.

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.
In ACGIH (7th, 2001), PATTY (4th, 1994), HSDB (2005), HSFS (2000), and SITTIG (4th, 2002), symptoms accompanied by anesthesia actions such as sleepiness, giddiness, headache, anxiety, mental poor concentration, nausea have been confirmed at low level exposure to humans, while central nervous system symptoms such as excitement, directions sensory paralysis, impaired judgement, memory loss, confusion, muscle aches, trembles, spasms, muscular stiffness of face, neck, trunk and limbs, opisthotonus, and comas have been described at high exposure levels. It was judged as Category 1 (central nervous systems) and Category 3 (anesthetic actions). Moreover, it was judged as Category 3 (respiratory irritant) based on descriptions in HSFS (2000) and SITTIG (4th, 2002) referring to that noses, throats, and lungs were stimulated and coughs, sneezes, and breathlessness were caused.
9 Specific target organ toxicity - Repeated exposure Category 1 (central nervous system, liver) Danger H372: Cause damage to organs through prolonged or repeated exposure (central nervous system, liver) 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 ...
Based on descriptions that excitement and tremor were observed in the four-week inhalation exposure test on rats (ACGIH (7th, 2001)), that hypoesthesia and hypalgesia, ataxia, and tremor were observed in six month inhalation exposure test on apes, dogs, rabbits, rats, and hamsters (PATTY (4th, 1994)), and that character change, such as depression, anxiety, and hypersensitivity, and effects on liver and brain were occured on humans (HSFS (2000)), it was classified into Category 1 (central nervous systems, liver).
