[Rationale for the Classification] Based on (1) and (2), it was classified in Category 1. [Evidence Data] (1) This substance is irritating to the skin, eyes and respiratory organs (HSDB (Access on July 2019)). (2) It is reported that this substance is severely irritating or corrosive to the mucous membranes and skin in humans (GESTIS (Access on August 2019)). [Reference Data, etc.] (3) It was classified as "Skin Corr. 1B (H314)" in the EU CLP classification (EU CLP classification (Access on July 2019)). |

Danger |
H318 |
P305+P351+P338
P280 P310 |
[Rationale for the Classification] Based on (1)-(4), it was classified in Category 1. [Evidence Data] (1) Based on a report that this substance causes severe irritation or corrosion to the mucous membranes and skin of humans (GESTIS (Access on August 2019)), it was classified in skin corrosion (Category 1). (2) There is a description that the fumes of this substance cause irritation of the eyes (ACGIH (7th, 2001), HSDB (Access on July 2019)). (3) There is a description that the vapor or fume of this substance is very irritating to all mucous membranes (PATTY (6th, 2012)).

Danger |
H370 |
P308+P311
P260 P264 P270 P321 P405 P501 |
[Rationale for the Classification] Based on (1)-(3), it was classified in Category 1 (respiratory organs). The circulatory system also was adopted as a target organ in the previous classification, based on descriptions in HSDB (2005) adopted as evidence. However, these were described as general effects from various acids in HSDB (Access on July 2019), and it was unknown whether it was due to the effect of this substance alone. Since there was no other information to support the effects on the circulatory organ system, the classification result was changed. [Evidence Data] (1) There is a report that the fumes of this substance caused irritation of the eyes and respiratory passages, and that exposure caused cases of bronchitis (ACGIH (7th, 2001)). (2) The vapor or fume of this substance is very irritating to all mucous surfaces including the lungs (OEL Documentations (Japan Society For Occupational Health (JSOH), 1989), PATTY (6th, 2012)). (3) As for humans, it was reported that the vapor of this substance caused irritation to the eyes and respiratory tract, and that secretion from the nose, cough, pain in the throat and difficulties in breathing as well as pulmonary edema were observed in some cases (GESTIS (Access on July 2019)). [Reference Data, etc.] (4) Under moisture in the air, this substance hydrolyzes to generate hydrogen chloride (CAS RN 7647-01-0) and phosphoric acid (CAS RN 7664-38-2) (OEL Documentations (Japan Society For Occupational Health (JSOH), 1989), GESTIS (Access on July 2019)). Both hydrogen chloride and phosphoric acid are corrosive and irritating, and the effects on the respiratory organs were reported (hydrogen chloride: SIDS (2005), phosphoric acid: SIDS (2011)). |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (bone) |
Warning |
H373 |
P260
P314 P501 |
[Rationale for the Classification] Based on (1), it is considered that inhalation causes effects on the bone in humans. Since it was information on phosphorus and phosphorus compounds, not this substance itself, it was classified in Category 2 (bone). [Evidence Data] (1) Chronic inhalation of phosphorus and chloro compounds of phosphorus causes damage to bony tissue in humans (HSDB (Access on July 2019)). [Reference Data, etc.] (2) In experimental animals, chronic exposure to the oxychloride, trichloride and pentachloride of phosphorus caused morphologic changes of the liver, bone, kidneys and lungs. Moreover, pathological examination in the respiratory passages resulted in desquamative rhinitis, tracheitis and bronchitis (HSDB (Access on July 2019)). |
