Warning |
H351 | P308+P313 P201 P202 P280 P405 P501 |
[Rationale for the Classification] Based on (1) to (2), it was classified in Category 2. [Evidence Data] (1) As for classification results by domestic and international organizations, this substance was classified in Group 3 by IARC, "not classifiable or a Group D chemical (under the 1986 guidelines)" or "cannot be determined, but for which there is suggestive evidence that raises concern for carcinogenic effects (under the 1996 guidelines)" by EPA (IRIS (1998), and DFG MAK classified as Category 3B (DFG MAK (2015)). (2) In a carcinogenicity study by two-year inhalation exposure with rats, pulmonary adenomas in 6/60 males and 2/60 females and pulmonary adenocarcinomas in 1/60 males were observed at the highest concentration of 6.0 mg/m3 (DFG MAK (2008), IRIS (1998), AICIS (previous NICNAS) IMAP (2013)). [Reference Data, etc.] (3) After long-term exposure of rats to this substance, preneoplastic and neoplastic changes were observed in the lungs. A mechanism of tumor formation by cell proliferation associated with chronic inflammation was assumed (DFG MAK (2008)). |

Danger |
H370 | P308+P311 P260 P264 P270 P321 P405 P501 |
[Rationale for the Classification] Based on (1) to (3), it was classified in Category 1 (respiratory organs). [Evidence Data] (1) It was reported that short-term exposure to this substance could cause irritation of the eyes and respiratory tract (DFG MAK (2008)). (2) It was reported that the aerosol mixture of this substance being used to apply an insulator to the insides of railway carriages was blown by the wind, a group of 12 workers standing 20 to 40 meters away was exposed to the mixture, and within two hours, all twelve developed symptoms such as pain behind the eyes, nasal discharge, retrosternal soreness, constriction of the chest, coughing and headaches. The symptoms regressed within a few days (DFG MAK (1992)). (3) It was reported that in an acute inhalation (vapor) exposure test with rats (for four hours), in the 0.384 mg/L and 0.523 mg/L (within the range for Category 1) groups, labored breathing and mouth breathing during the exposure were observed, some hemorrhages in the lungs and hemorrhagic fluid around the noses were observed in a few animals that died, and the lungs of most animals in the highest dose group were grayish white and wet (REACH registration dossier (Accessed Oct. 2020), NICNAS IMAP (2013), DFG MAK (1992)). |

[Rationale for the Classification] Based on (1) to (3), it was classified in Category 1 (respiratory organs). [Evidence Data] (1) According to a report on repeated exposure effects in humans, an impairment of lung function was observed at the PMDI (polymeric methylene diphenyl diisocyanate) concentration of as low as 87 ppb (0.9 mg/m3); at the concentration of 20 ppb (0.2 mg/m3), no changes in lung spirometry were found, although airway symptoms occurred; and after exposure to the PMDI concentration of below 10 ppb (0.1 mg/m3), the frequency of respiratory complaints did not significantly increase (DFG MAK (2008)). (2) It was reported that in a 13-week inhalation exposure test with rats (aerosol, 6 hours/day, 5 days/week), an increase in alveolar macrophages, interstitial macrophage infiltration and macrophages with yellowish inclusions in the lungs in the mediastinal lymph nodes were observed at 4.1 mg/m3 and above (converted guidance value: 0.0029 mg/L, within the range for Category 1), damages to the olfactory epithelium and basal cell hyperplasia in the nasal cavity were observed at or above 8.4 mg/m3 (converted guidance value: 0.0059 mg/L, within the range for Category 1), and reduced body weight gain was observed and 11/30 males and 4/30 females died of severe respiratory failure at 12.3 mg/m3 (converted guidance value: 0.0088 mg/L, within the range for Category 1) (DFG MAK (1992)). (3) It was reported that in a two-year inhalation exposure test with rats (aerosol, 6 hours/day, 5 days/week), effects on the nasal cavity (degeneration and basal cell hyperplasia of the olfactory epithelium, hyperplasia of Bowman's gland), the lungs (increase in alveolar macrophages, localized fibrosis, epithelialization of the alveolar duct) and the mediastinal lymph node (macrophages with yellowish inclusions) were observed at 1.0 mg/m3 and above (0.001 mg/L, within the range for Category 1) (DFG MAK (2008), AICIS (previous NICNAS) IMAP (2013), REACH registration dossier (Accessed Oct. 2020)). |
