P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment (see ... on this label).
P362: Take off contaminated clothing and wash before reuse.
From the description with the possibility which indicates skin irritation in humans (DFGOT, vol.15, 2001 [as inorganic mercury compounds]; HSFS, 2001[irritate and burn]), it was thought that there was irritation and it was set as Category 2.

P337+P313: If eye irritation persists: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
Due to the description that it may irritate to the eye (HSFS, 2001), it was classified into Category 2B.
4 Respiratory sensitization Classification not possible - - - - No data available
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.

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 metallic mercury and inorganic mercury compound (as Hg) were made into those with skin sensitization (MAK/BAT, 2005; DFGOT, vol.15, 2001), they were set to Category 1.
5 Germ cell mutagenicity Category 2 Warning H341: Suspected of causing genetic defects 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 ...
In ATSDR (1999), since it estimated that mercury and mercury compounds induced chromosomal abnormality to the animal somatic cell in an in vivo, they were set to Category 5.
6 Carcinogenicity Not classified - - - - As inorganic mercury compounds, it was out of the Category. Since it is classified into IARC Group 3 (IARC, 58, 1993) and ACGIH A4 (ACGIH-TLV, 2004).

P271: Use only outdoors or in a well-ventilated area.
P312: Call a POISON CENTER or doctor/physician if you feel unwell.
The substance was classified as Category 1 (kidneys) and Category 3 (airway irritant) based on the reports concerning humans in Priority 1 documents that the target organs of the substance in the inorganic mercury compound are the kidneys (DFGOT, vol.15, 2001), and the report of respiratory organ irritant properties in humans in a Priority 2 document (HSFS, 2001).
9 Specific target organ toxicity - Repeated exposure Category 1 (central nervous system, kidney) Danger H372: Cause damage to organs through prolonged or repeated exposure (central nervous system, kidney) 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 ...
Since the effect on the central nervous system and the kidney to humans by inorganic mercury compounds is indicatted in Priority 1 document (ACGIH-TLV, 2004;EHC, 118, 1991), and the effect on the kidney was suggested in Priority 2 document (HSFS, 2001), it was classified into Category 1 (central nervous systems,kidney).
