4 Respiratory sensitization Category 1 Danger H334: May cause allergy or asthma symptoms or breathing difficulties if inhaled P304+P341: IF INHALED: If breathing is difficult, remove victim to fresh air and keep at rest in a position comfortable for breathing.
P342+P311: If experiencing respiratory symptoms: Call a POISON CENTER or doctor/physician.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P285: In case of inadequate ventilation wear respiratory protection.
P501: Dispose of contents/container to ... 		Since nickel and its compounds are classified into Category 2 for respiratory tract sensitizer (Recommendations for allowable concentrations (2009)) in Japan Society For Occupational Health (JSOH), the substance was classified into Category 1. As relevant information, in the MAK table of DFG (Germany), "Sah" mark is assigned.
4 Skin sensitization Category 1 Warning H317: May cause an allergic skin reaction P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P333+P313: If skin irritation or rash occurs: Get medical advice/attention.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P272: Contaminated work clothing should not be allowed out of the workplace.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment （see ... on this label）.
P363: Wash contaminated clothing before reuse.
P501: Dispose of contents/container to ... 		Since nickel and its compounds are classified into Category 1 for skin sensitizer in Japan Society For Occupational Health (JSOH), (Recommendations for allowable concentrations (2009)) and are classified into R43 in EU classification, the substance was classified into Category 1. As relevant information, in the MAK table of DFG (Germany), "Sah" mark is assigned.
5 Germ cell mutagenicity Not classified - - - - Based on a negative result in an inhalation mouse peripheral blood micronucleus test (in vivo somatic cell mutagenicity test) (NTP DB (access on Oct. 2009)), the substance was classified as "Not classified". As relevant information, from in vitro mutagenicity tests, there are reports of an equivocal Ames test (NTP DB (access on Oct. 2009)), positive human lymphocyte chromosomal aberration and micronucleus tests (NTP TR453 (1996)), and positive gene mutation tests using CHO cell and rat hepatocyte (DFGOT vol. 22 (2006)).
6 Carcinogenicity Category 1A Danger H350: May cause cancer P308+P313: IF exposed or concerned: Get medical advice/attention.
P201: Obtain special instructions before use.
P202: Do not handle until all safety precautions have been read and understood.
P281: Use personal protective equipment as required.
P405: Store locked up.
P501: Dispose of contents/container to ... 		Since nickel compounds are classified into "Group 1" in IARC (IARC 49 (1990)), the substance was classified into Category 1A. Nickel compounds are classified into Category 1 in Japan Society For Occupational Health (JSOH) (Recommendations for allowable concentrations (2005)). Nickel subsulfide is classified into "A1" in ACGIH (ACGIH (2001)). In a rat 2-year inhalation test, there was clear evidence of carcinogenic activity of nickel subsulfide in rats based on exposure-related increases in the incidences of alveolar/bronchiolar adenoma and carcinoma and significant increases in the incidences of pheochromocytoma of the adrenal medulla (NTP TR453 (1996)). There was no evidence of carcinogenic activity in mice exposed by inhalation for 2 years (NTP TR453 (1996)).

As relevant information, there is a report that the number of live fetuses per litter was decreased when rats received intramuscular injection on day 6 of gestation (EHC 108 (1991), PATTY (5th, 2001), IARC vol. 49 (1990)).
8 Specific target organ toxicity - Single exposure Classification not possible - - - - No data available. As relevant information, in a rat intratracheal test, inflammation, hemorrhage and alveolitis in the lung were observed (EHC 108 (1991), IARC vol. 49 (1990)).
9 Specific target organ toxicity - Repeated exposure Category 1 (respiratory system) Danger H372: Cause damage to organs through prolonged or repeated exposure (respiratory system) P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P314: Get medical advice/attention if you feel unwell.
P501: Dispose of contents/container to ... 		It was reported that high risk of mortality from respiratory disease is found among workers exposed occupationally to nickel oxides and metal nickel at concentrations of 0.04 mg/m3 and higher. In addition, rhinitis, sinusitis, nasal septal perforations and dysplasia of the nasal mucosa were reported in nickel refinery and nickel plating workers (Risk assessment report of nickel and nickel compounds (Ministry of Health, Labour and Welfare) (2009)). Based on the data, the substance was classified into Category 1 (respiratory system). In addition, in rat and mouse inhalation tests (0, 0.15, 0.3, 0.6, 2.5 mg/m3, 6 h/day, 13 week), chronic inflammation of the lung, lymphoid hyperplasia of the bronchial and mediastinal lymph nodes were observed in male and female rats exposed to 0.3 mg/m3 and higher concentrations. Atropy of the nasal olfactory epithelium was observed in male and female rats and mice exposed to 0.6 mg/m3 and higher concentrations. Chronic inflammation of the lung, lymphoid hyperplasia of the bronchial and mediastinal lymph nodes were observed in male and female mice exposed to 1.2 mg/m3 and higher concentrations (NTP TR453 (1996), Hazard Assessment Report (CERI, NITE) (2007), ECETOC TR-33 (1989)). These toxic effects were observed at dose levels within the guidance value range for Category 1.
10 Aspiration hazard Classification not possible - - - - No data available.
