Irritation to the human upper respiratory tract is reported (ICSC, 2002; HSDB, 2002). Moreover, since irritation and breathing difficulty were reported by the inhalation test with rats (ACGIH, 2001), it was set as Category 3 (respiratory irritant). | |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (nervous system, lung, eye) | Warning | H373: May cause damage to organs through prolonged or repeated exposure (nervous system, lung, eye) |
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 ... |
Effects on nervous system (reduction in an spontanous motor activity, tremor), alveolar-epithelium hypertrophy and ocular opacity were reported in the oral administration examination using the rat (Health, Labor and Welfare Ministry reports). Based on each value rectified by the administration period and the result compared with the guidance value on the 90th, it was classified to as Category 2 (a nervous system, lungs, eye). | |
