HEALTH HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification	Classification year (FY)	GHS Classification Guidance for the Japanese Government
1	Acute toxicity (Oral)	Category 3	Danger	H301	P301+P310 P264 P270 P321 P330 P405 P501	Based on the rat LD50 (oral route) value of 210mg/kg (RTECS (2005)).	FY2006	GHS Classification Manual （10 Feb, 2006）
1	Acute toxicity (Dermal)	Category 4	Warning	H312	P302+P352 P362+P364 P280 P312 P321 P501	Based on the rabbit LD50 (dermal route) value of 1,500mg/kg (RTECS (2005)).	FY2006	GHS Classification Manual （10 Feb, 2006）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Due to the fact that the substance is "solid" according to the GHS definition and inhalation of its gas is not expected.	FY2006	GHS Classification Manual （10 Feb, 2006）
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	No data available	FY2006	GHS Classification Manual （10 Feb, 2006）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data available	FY2006	GHS Classification Manual （10 Feb, 2006）
2	Skin corrosion/irritation	Category 2	Warning	H315	P302+P352 P332+P313 P362+P364 P264 P280 P321	Based on the description in ICSC (J) (2000): "flare and irritation of the eye/skin/respiratory tract." The substance is thus considered to cause skin irritation (though the severity of the effects is not presented) and classified into Category 2 from the viewpoint of safety.	FY2006	GHS Classification Manual （10 Feb, 2006）
3	Serious eye damage/eye irritation	Category 2A	Warning	H319	P305+P351+P338 P337+P313 P264 P280	Based on the description in ICSC (J) (2000): "flare and irritation of the eye/skin/respiratory tract." The substance is thus considered to cause eye irritation (though the severity of the effects is not presented) and classified into Category 2A-2B from the viewpoint of safety.	FY2006	GHS Classification Manual （10 Feb, 2006）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available	FY2006	GHS Classification Manual （10 Feb, 2006）
4	Skin sensitization	Category 1	Warning	H317	P302+P352 P333+P313 P362+P364 P261 P272 P280 P321 P501	Mercury is classified into a "Skin Sensitizing Substance" by the ad hoc committee of the Japanese Society of Occupational Allergy, and "Skin Sensitizing Substance: Group 1"* by the Japan Society for Occupational Health. These classifications, though not specifying mercurous chloride, seem to include mercury compounds. Mercurous chloride, which is a mercury compound, should thus cause skin sensitization. * There is a provision to the effect that "the category refers to the substance concerned and its compounds, but does not identify all substances causing respiratory/skin sensitization.	FY2006	GHS Classification Manual （10 Feb, 2006）
5	Germ cell mutagenicity	Classification not possible	- -	-	-	No data available As for the mutagenicity/genotoxicity, refer to "ID285, Mercury Chloride (II), CAS: 7487-94-7."	FY2006	GHS Classification Manual （10 Feb, 2006）
6	Carcinogenicity	Not classified	- -	-	-	Due to the fact that the substance is classified as Category A4 (as metal mercury and inorganic mercury compounds) by ACGIH (2001) and Group 3 (as metal mercury and inorganic mercury compounds) by IARC (1993).	FY2006	GHS Classification Manual （10 Feb, 2006）
7	Reproductive toxicity	Classification not possible	- -	-	-	No data available As for the reproductive toxicity, refer to "ID285, Mercury Chloride (II), CAS: 7487-94-7."	FY2006	GHS Classification Manual （10 Feb, 2006）
8	Specific target organ toxicity - Single exposure	Category 1 (kidney), Category 3 (respiratory tract irritation)	Danger Warning	H370 H335	P308+P311 P260 P264 P270 P321 P405 P501 P304+P340 P403+P233 P261 P271 P312	Based on the human evidence: "decreased urinary output and edema were observed; renal failure was regarded as a contributing factor of death." (CICAD 50 (2003)) and "eye/skin/respiratory irritation" (ICSC(J) (2000)). Note: According to CICAD 50 (2003), "renal failure, cardiovascular collapse and severe digestive organ damage are considered to be the causes of death following oral exposure to inorganic mercury. Most common findings among these are gastrointestinal tract lesion and renal failure. Exposure to inorganic mercury appears to induce nephrotic syndrome in humans."	FY2006	GHS Classification Manual （10 Feb, 2006）
9	Specific target organ toxicity - Repeated exposure	Category 1 (kidney, nervous system, gastrointestinal tract)	Danger	H372	P260 P264 P270 P314 P501	Based on the human evidence including "abdominal pain, nausea, vomiting, black feces, decreased urinary output and renal failure; irritability, fretfulness, sleeplessness, weakness, photophobia, muscle twitching, hyperactive or hypoactive tendon reflexes, confusion, irregular arm movements, and impaired gait" (CICAD 50 (2003)), "dementia and irritability; reduced brain weight observed at necropsy; decreased cerebellar neurons; mercury granules in the cytoplasm found at the light microscopic level" (ATSDR (1994)). Since gastrointestinal tract effects were observed in the repeated dose toxicity studies using the dermal route of exposure, it is unlikely that these effects represented a direct toxic effect, so the GI tract was included in the target organ list.	FY2006	GHS Classification Manual （10 Feb, 2006）
10	Aspiration hazard	Classification not possible	- -	-	-	No data available	FY2006	GHS Classification Manual （10 Feb, 2006）
