Based on LC50 (4h) values of 2.4 mg/L (486 ppm)(male) and 2.2 mg/L (450 ppm)(female) (SIDS (1997)) and 500 ppm (ATSDR (1998)) for rats, the substance was classified into Category 2. Since the LD50 values were lower than 90% of saturated vapour pressure concentration (1158 ppm), the classification criteria for gas was adopted.
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.

Based on a result of "irritating" in a rabbit test (similar to OECD TG404) where severe erythema with eschar and oedema were observed in 3/6 rabbits after a 4-hour application (SIDS (1997)), the substance was classified into Category 2. As relevant information, there is a report that some reddening of the skin and contact dermatitis occurred in cleaners using floor strippers containing high levels of the substance (SIDS (1997)).
3 Serious eye damage/eye irritation Category 2A Warning H319: Causes serious eye irritation P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P337+P313: If eye irritation persists: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
In rabbit Draize tests (OECD TG405 (GLP)), corneal opacity, iritis, conjunctival redness and chemosis were observed. Corneal opacity and iritis reversed but conjunctival redness and chemosis persisted at 7 days after application. The MMAS (Maximum Average Score) was calculated to be 68.7 (ECETOC TR48 (1998)). Since the MMAS value corresponds to an AOI (acute ocular irritation index) of 30 - 80 and conjunctival redness and chemosis were observed after 7 days, the substance was classified into Category 2A.
4 Respiratory sensitization Classification not possible - - - - No data available.
4 Skin sensitization Not classified - - - - Based on negative results in 2 maximization tests using guinea pigs (SIDS (1997)) and a human repeated insult patch test (SIDS (1997)), the substance was classified as "Not classified".
5 Germ cell mutagenicity Not classified - - - - Based on negative results in rat and mouse bone marrow micronucleus tests by intraperitoneal administration (in vivo somatic cell mutagenicity test) (SIDS (1997), CICAD 10 (1998)) and a report that no increases in micronuclei or sister chromatid exchanges were observed in epidemiological research (ATSDR (1998)), the substance was classified as "Not classified". As relevant information, from in vitro mutagenicity tests, there are reports of negative results for an Ames test (SIDS (1997)), a human lymphocyte chromosomal aberration test (ECETOC 95 (2005)), a chromosomal aberration test, a gene mutation test using CHO cells (SIDS (1997)) and a CHL cell gene mutation test (ATSDR (1998)).
6 Carcinogenicity Not classified - - - - The substance is classified into "Group 3" in IARC (IARC 88 (2006)), "A3" in ACGIH (ACGIH (7th, 2003)) and "C" in EPA (IRIS (1999)). Although these assessment documents classified the substance in different categories, it was classified as "Not classified" in accordance with the latest classification in IARC ("Group 3"). In 2-year inhalation tests in rats and mice, incidences of forestomach squamous cell papilloma was significantly increased in females and the incidence of hemangiosarcoma of the liver was significantly increased in males (NTP 484 (2000)).
7 Reproductive toxicity Category 2 Warning H361: Suspected of damaging fertility or the unborn child 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.

Inhalation of the substance by rats and rabbits throughout gestation was associated with embryotoxicity, as evidence by a decreased number of implantations and an increased number of resorptions. At the same doses, dams exhibited general toxicity such as decreased body weight, increased kidney weight and changes in hematological parameters (SIDS (1997)). Based on the data the substance was classified into Category 2. An epidemiology test suggested the risk of cleft lip, however, the association with the substance is not clear (PATTY (5th, 2001)).

The effects on erythrocyte are characteristic in animals exposed to the substance (SIDS (1997)). There are human cases that demonstrated hematological effects such as decreased hemoglobin and/or erythrocyte counts, and hemoglobinuria. Additionally, it is reported that exposed individuals exhibited symptoms such as coma, dizziiness, breathing difficulties, metabolic acidosis, hematuria and liver dysfunction (SIDS (1997)). There are some reports of severe cases resulting in hospitalization of the exposed individuals (SIDS (1997), PATTY (5th, 2001)). Based on all human information, the substance was classified into Category 1 (central nervous system, blood system, kidney, liver). In addition, since there are reports of "nasal and throat irritation" in a human inhalation test (SIDS (1997)) and "recurrent respiratory irritation, and dry cough" in a case report (HSDB (2004)). Based on these results, the substance was classified into Category 3 (respiratory tract irritation).
9 Specific target organ toxicity - Repeated exposure Category 2 (blood) Warning H373: May cause damage to organs through prolonged or repeated exposure (blood) P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P314: Get medical advice/attention if you feel unwell.
P501: Dispose of contents/container to ...
In a 90-day inhalation test, male and female rats exposed to 77 ppm exhibited hematological changes such as a decrease in red blood cell count, hemoglobin concentration and hematocrit as well as an increase in mean corpuscular hemoglobin (SIDS (1997)). In a 14-week inhalation test in male and female rats, anemia was present in males rats at 125 pm or higher concentrations and in female rats of all exposed groups. The anemia was characterized as normochromic and regenerative (PATTY (5th, 2001)). Based on these evidences of anemia, the substance was classified into Category 2 (blood system).

ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Not classified - - - - Classified into Not classified from its 96h-LC50 >116 mg/L for fish (Sheepshead minnow) (Initial Environmental Risk Assessment of Chemicals (Ministry of the Environment) vol. 6 (2008), etc) and 96h-LC50 >130 mg/L for Crustacea (Penaeus) (Initial Environmental Risk Assessment of Chemicals (Ministry of the Environment) vol. 6 (2008), etc).
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - Classified into Not classified since it is rapidly degradable (BOD degradation rate: 96% (Biodegradation and Bioconcentration of Existing Chemical Substances under the Chemical Substances Control Law, 1976)) and low bioaccumulative potential is estimated (log Kow = 0.83 (PHYSPROP Database, 2009)).
12 Hazardous to the ozone layer Classification not possible - - - - This substance is not listed in Annexes to the Montreal Protocol.
