1	Acute toxicity (Inhalation: Dusts and mists)	Category 4	Warning	H332	P304+P340 P261 P271 P312	[Rationale for the Classification] Base on (1), it was classified in Category 4. Besides, since exposure concentrations are higher than the saturated vapour concentration (0.50 mg/L), the reference value in units of mg/L was applied as the dust. [Evidence Data] (1) LC50 (7 hours) for rats: 165 ppm (converted 4-hour equivalent value: 4.65 mg/L) (ACGIH (7th, 2001), HSDB (Access on July 2019)), 183 ppm (converted 4-hour equivalent value: 5.16 mg/L) (PATTY (6th, 2012))	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))

4	Respiratory sensitization	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
4	Skin sensitization	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	[Rationale for the Classification] There are no in vivo data. Therefore, classification was not possible due to lack of data. [Evidence Data] (1) As for in vitro, positive results in bacterial reverse mutation tests and a negative result in a mammalian cell chromosomal aberration test were reported (NTP DB (Access on July 2019)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
6	Carcinogenicity	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data. [Reference Data, etc.] (1) In carcinogenicity tests in which this substance was administered by gavage to rats and mice for 78 weeks, no increases in the incidences of any tumors in rats or mice were noted. However, because of poor survival in male rats, the possibility of causing thyroid tumors cannot be excluded. Therefore, it was concluded that under these tests, no convincing evidence was provided for the carcinogenicity of this substance (NTP TR110 (1978)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
7	Reproductive toxicity	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))

As for the kidney, liver and heart, as detailed information was not obtained, they were not adopted as target organs. [Evidence Data] (1) There is a description that when used as a topical antiseptic in medical applications in humans, percutaneous absorption through a wound may result in acute depression of the central nervous system and systemic toxicity such as vomiting, tachycardia, coma, and damage to the kidneys, liver, and heart (ACGIH (7th, 2001), PATTY (6th, 2012)). (2) There is a report that by a single oral or dermal dose to rats, mice, and guinea pigs, drowsiness and low activity were first observed, and bloody nasal exudate, breathing disturbances, tonic-clonic convulsions, and paralysis of the extremities preceded death (PATTY (6th, 2012), HSDB (Access on July 2019)). (3) There are reports that application of this substance to wounds in dogs and cats resulted in poisoning, which was characterized by vomiting, muscular spasms, a lowered temperature, cardiac depression and drowsiness (PATTY (6th, 2012)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
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) Systemic poisoning from iodoform can result from percutaneous absorption through a wound. At least one instance of delirium and hallucinations was attributed to iodoform intoxication (ACGIH (7th, 2001)). (2) There are results of carcinogenicity tests with rats and mice (NTP TR110 (1978)), however, it was described in ACGIH that the histopathologic examination was inadequate for the results of these tests (ACGIH (7th, 2001)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
10	Aspiration hazard	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
