P281: Use personal protective equipment as required.
P372: Explosion risk in case of fire.
P374: Fight fire with normal precautions from a reasonable distance.

Since the substance, which is wetted with less than 20% water or alcohol by mass, is prohibited from being transported (Ship Safety Act / Article 5-1(o) of Public Notice of the Ministry of Transport, No.549 of 1979), we determined that it is an unstable explosive. (If the substance is wetted with not less than 20% water or alcohol by mass, it is defined as UN0129 and Division 1.1.)
2 Flammable gases (including chemically unstable gases) Not applicable - - - - Solid
3 Aerosols Not applicable - - - - Not aerosol products.
4 Oxidizing gases Not applicable - - - - Solid
5 Gases under pressure Not applicable - - - - Solid
6 Flammable liquids Not applicable - - - - Solid
7 Flammable solids Classification not possible - - - - No data available.
8 Self-reactive substances and mixtures Not applicable - - - - Since the substance is classified as an explosive, classification as a self-reactive substance is not applicable.
9 Pyrophoric liquids Not applicable - - - - Solid
10 Pyrophoric solids Classification not possible - - - - No data available.
11 Self-heating substances and mixtures Classification not possible - - - - No data available.
12 Substances and mixtures which, in contact with water, emit flammable gases Not classified - - - - Based on its water solubility value (Merck (14th, 2006)), we determine that the substance is stable in contact with water.
13 Oxidizing liquids Not applicable - - - - Solid
14 Oxidizing solids Not applicable - - - - The substance does not contain oxygen or halogen.
15 Organic peroxides Not applicable - - - - Inorganic substance
16 Corrosive to metals Classification not possible - - - - No data available.

HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Classification not possible - - - - No data available.
1 Acute toxicity (Dermal) Classification not possible - - - - No data available.
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Solid
1 Acute toxicity (Inhalation: Vapours) Classification not possible - - - - No data available.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - - No data available.
2 Skin corrosion/irritation Classification not possible - - - - According to HSFS (1998), skin contact with the substance can cause irritation. However, since we are unable to locate test results that support this conclusion, the substance was classified into the "Classification not possible" category due to insufficient test results available.
3 Serious eye damage/eye irritation Classification not possible - - - - According to HSFS (1998), eye contact with the substance can cause irritation. However, since we are unable to locate test results that support this conclusion, the substance was classified into the "Classification not possible" category due to insufficient test results available.
4 Respiratory sensitization Classification not possible - - - - No data available.
4 Skin sensitization Classification not possible - - - - No data available.
5 Germ cell mutagenicity Classification not possible - - - - No test results are available on this substance. Lead is reported to induce chromosomal aberrations in humans (ATSDR (2007)) and inorganic lead compounds are rated as "3A" for germ cell mutagenicity (which is equivalent to GHS Category 1B to 2) (MAK/BAT (2007).
6 Carcinogenicity Category 1B 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 ...
Inorganic lead is rated as "Group 2A" according to IARC V87 (2006), and lead azide is illustrated as an example of inorganic lead. Based on this report, lead azide was classified into Category 1B.
7 Reproductive toxicity Category 1A Danger H360: May damage fertility or the unborn child 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 ...
No test results are available on this substance. However, since inorganic lead compounds are associated with reproductive toxicity in humans (ACGIH-TLV (2007), ATSDR (2007)), this substance was classified into Category 1A.
8 Specific target organ toxicity - Single exposure Category 1 (central nervous system, blood, kidney) Danger H370: Causes damage to organs (central nervous system, blood, kidney) P307+P311: IF exposed: Call a POISON CENTER or doctor/physician.
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.
P321: Specific treatment (see ... on this label).
P405: Store locked up.
P501: Dispose of contents/container to ...
No test results are available on this substance. However, since inorganic lead compounds adversely affect the central nervous system, blood, and kidney in humans (ACGIH-TLV (2007), ATSDR (2007)), this substance was classified into Category 1 (central nervous system, blood, and kidney).
9 Specific target organ toxicity - Repeated exposure Category 1 (central nervous system, blood, kidney) Danger H372: Cause damage to organs through prolonged or repeated exposure (central nervous system, blood, 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 ...
No test results are available on this substance. However, since inorganic lead compounds adversely affect the central nervous system, blood, and kidney (ACGIH-TLV (2007)), this substance was classified into Category 1 (central nervous system, blood, and kidney).
10 Aspiration hazard Classification not possible - - - - No data available.
