Its flash points are 5degC (closed cup, IMDG vol.2 (2006)), 22.8degC (closed cup, Weiss (1986)), and 17.8degC (Tag closed cup, HSDB (2002)), which are < 23degC; and its initial boiling point is 71degC (Merck No. 6043 (2006), Ullmanns (E) vol.8 (2003), Howard p.76 (1997)), which is > 35degC.

1 | Acute toxicity (Oral) | Category 3 |
Danger |
H301 | P301+P310 P264 P270 P321 P330 P405 P501 |
Based on the rat LD50 < 0.05g/kg (50mg/kg) (PATTY (5th 2001)), the substance would be classified into either Category 1 or 2. However, in other tests, the rat LD50 of 60mg/kg is not greatly different in value from the mouse LD50 of 67mg/kg and the guinea pig LD50 of 140mg/kg (RTECS (2006)), with these values rated as R22 in the EU classification (EU-Annex 1 (accessed in May 2008)). As such, the substance was classified into Category 3. | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |

Danger |
H330 | P304+P340 P403+P233 P260 P271 P284 P310 P320 P405 P501 |
The substance was classified into Category 1 since its rat LC50 = 88 ppm/1h (44 ppm/4h) (RTECS (2006)) and its EU classification is R26 (EU-Annex 1 (accessed in May 2008)). In these studies, since 88 ppm is <= 90% of saturated vapour pressure concentration, it was estimated the vapour with almost no included mistsvapour. In addition, the lethal dose for humans is 190 ppm/10minutes (PATTY 5th 2001: reported in 1948). | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |

The substance was classified into Category 1 since the substance caused damage to skin, and its contact to eyes and skin was highly irritating or corrosive in guinea pig studies (PATTY (5th 2001)). Similarly, the substance is reported to be a highly corrosive irritant according to HSDB (2002); and it is rated R34 in EU classification. | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |
3 | Serious eye damage/eye irritation | Category 1 |
Danger |
H318 | P305+P351+P338 P280 P310 |
The substance was classified into Category 1 since it is highly irritating and corrosive through contact to the eyes and skin (PATTY (5th 2001)) and because its preexisting classification for skin corrosion/irritation is Category 1. | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |

H371 | P308+P311 P260 P264 P270 P405 P501 |
In the human exposure cases, irritation, heavy cough, dyspnea, and light lip cyanosis were observed, and it took nine days for full recovery (HSDB (2002)). Thus, the substance was classified into Category 2 (respiratory system). | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |
