[Rationale for the Classification] Based on (1) and (2), it was classified in Category 1. The category was changed due to new data obtained. [Evidence Data] (1) There is no report of an irritation test on this substance. However, since the hydrolysate of this substance is calcium hydroxide (CAS RN 1305-62-0), and the pH of calcium hydroxide is 12-13, it should be judged as a corrosive substance (ECHA RAC Background document (2013), CLH Report (2012)). (2) This substance is irritating to the skin, eyes and respiratory organs (HSDB (Access on October 2019)). |

4 | Skin sensitization | Classification not possible |
- |
- | - | [Rationale for the Classification] Though there is a description in (1), it was classified as "Classification not possible" due to lack of data. [Reference Data, etc.] (1) There is no report of a sensitization test on this substance. However, zinc phosphide (CAS RN 1314-84-7), a substance similar to this substance, was negative in a skin sensitization test compliant with OECD TG 406. Therefore, this substance is also considered to be negative for sensitization (ECHA RAC Background document (2013), CLH Report (2012)). |

Danger |
H370 | P308+P311 P260 P264 P270 P321 P405 P501 |
[Rationale for the Classification] There are no data on this substance itself. However, based on (1)-(3), it was classified in Category 1 (central nervous system, respiratory organs). The classification result was changed from the previous classification by the use of the new information sources. [Evidence Data] (1) This substance hydrolyzes in contact with water, or in the gastrointestinal tract, to produce calcium hydroxide (CAS RN 1305-62-0) and phosphine (synonym: hydrogen phosphide, CAS RN 7803-51-2) (CLH Report (2012), ECHA RAC Background document (2013)). (2) There is a description that calcium hydroxide is a strong base and a caustic irritant to all exposed surfaces of the body, including the eyes and respiratory system in humans (ACGIH (7th, 2001)). (3) It is described that the main target organs of phosphine are the respiratory system (cough, sore throat, dyspnea, pulmonary edema, etc.) and the central nervous system (headache, vertigo, tremors, unsteady gait, convulsions, coma, etc.) (IPCS, PIM 865 (1997)). |

9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. [Reference Data, etc.] (1) This substance decomposes very rapidly in contact with water to produce calcium hydroxide (CAS RN 1305-62-0) and phosphine (synonym: hydrogen phosphide, CAS RN 7803-51-2) (CLH Report (2012)). (2) In the GHS classification project in FY2014, calcium hydroxide was classified as "Classification not possible" based on the following rationale. There are descriptions that chronic ingestion of this substance can result in inflammatory and ulcerous changes in the mouth and digestive tract by irritation (HSDB (Access on September 2014)), and that atrophic changes in the liver, kidney and stomach and inflammation in the small intestine were observed in a test in which rats were administered with drinking water for 3 months (IUCLID (2000)). However, details including the dose were unknown. (3) In the GHS classification project in FY2019, phosphine was classified as "Classification not possible" because there are no case reports, etc. of repeated exposure in humans, and no clear effects were observed in inhalation exposure studies in experimental animals at concentrations that allow repeated dose. |
