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 ... |
It was classified in Category 1 (respiratory tracts) from the descriptions in IRIS (1998) and CICAD 27 (2000) that the effects on the respiratory system, such as focal/multifocal alveolar and bronchioalveolar hyperplasia, and interstitial fibrosis of lungs were seen with the concentration of the guidance value range of Category 1 in the inhalation exposure test using the rat , and from the descriptions in ACGIH (7th, 2001), DFGOT (vol.8, 1997), CICAD 27 (2000), IARC 71 (1999), and Japan Society for Occupational Health Recommendation of Occupational Exposure Limits (1993) that the respiratory dysfunction and increase in generating of a lung disease were seen in human occupation exposure cases. | |
