Since its saturated vapour pressure concentration is 107300 ppm (25degC), the substance is completely a vapour under the test conditions. Based on its rat LC50 of 420 ppm/4h (PATTY (5th, 2001)), the substance was classified into Category 2 using the guidance values for gases | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |

Warning |
H336 | P304+P340 P403+P233 P261 P271 P312 P405 P501 |
As neurotic symptoms by nitrites such as butyl nitrite, vertigo, ataxia, lipothymia, sedation, and weakness are caused, and effects on the digestive organs, cardiovascular system, blood system, immune systems, etc. (especially, immune-compromising effects) are observed (Am. J. Addiction, 10, 2001, 79 - 94), and furthermore, since the substance is a designated drug by the Pharmaceutical Affairs Act, it was classified into Category 3 (narcotic effects). | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (blood) |
Warning |
H373 | P260 P314 P501 |
"Rats were exposed 7h/day for 60 days. At the dose of 300 ppm (6h/day for 90 days conversion, 0.78mg/L) equivalent to the guidance value of Category 2, body weights, organ weights, and methemoglobinemia were the major reported parameters affected under these exposure conditions" (PATTY (5th, 2001)). Therefore, the substance was classified into Category 2 (blood). | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |
