Regarding this substance, mechanically manufactured powder with its particle diameter less than 53 microns and chemically manufactured power with its particle diameter less than 840 microns wetted with water are defined as UN1358 and Division 4.1 II by the UNRTDG, which is equivalent to Category 1. Since the dry form of the substance is more readily flammable, they are all classified into Category 1.
8 Self-reactive substances and mixtures Not applicable - - - - There are no chemical groups present in the molecule associated with explosive or self-reactive properties.
9 Pyrophoric liquids Not applicable - - - - Solid (GHS definition)
10 Pyrophoric solids Category 1 or Not classified Danger H250: Catches fire spontaneously if exposed to air P335+P334: Brush off loose particles from skin. Immerse in cool water/wrap in wet bandages.
P370+P378: In case of fire: Use ... for extinction.
P210: Keep away from heat/sparks/open flames/hot surfaces. ? No smoking.
P222: Do not allow contact with air.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P422: Store contents under ...
Dry powder products can be differentiated into the UNRTDG's UN2008, Division 4.2, packing group I, II, or III by tests. Products in packing group I are classified into Category 1 while those in packing groups II and III are classified into the "Not classified" category. (Products wetted with water are defined as UN1358 or the "Not classified" category.)
11 Self-heating substances and mixtures Category 1 or Category 2 Danger H251: Self-heating; may catch fire P235+P410: Keep cool. Protect from sunlight.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P407: Maintain air gap between stacks/pallets.
P413: Store bulk masses greater than ... kg/... lbs at temperatures not exceeding ... degC/... degF.
P420: Store away from other materials.
Dry powder products can be differentiated into the UNRTDG's UN2008, Division 4.2, packing group I, II, or III by tests. Products in packing group I and II are classified into Category 1 while those in packing group III are classified into Category 2. (Products wetted with water are defined as UN1358 or the "Not classified" category.)
12 Substances and mixtures which, in contact with water, emit flammable gases Not classified - - - - Since the substance can be wetted with water, we determined that it is stable in contact with water and classified it into the "Not classified" category.
13 Oxidizing liquids Not applicable - - - - Solid (GHS definition)
14 Oxidizing solids Not applicable - - - - Inorganic substance containing no oxygen and halogen atoms
15 Organic peroxides Not applicable - - - - Inorganic substance
16 Corrosive to metals Classification not possible - - - - No data available.

HEALTH HAZARDS

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 (GHS definition)

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 ...
There are several epidemiological study reports that the substance induces skin sensitization involving epithelioid granulomas (DFGOT 1999). Based on this report, the substance was classified into Category 1. As additional background information, the substance is rated as Sah (respiratory and skin allergens) by MAK/BAT (2006).
5 Germ cell mutagenicity Classification not possible - - - - No data available.
6 Carcinogenicity Not classified - - - - Since the substance is rated as "A4" by ACGIH (2001), it was classified into the "Not classified" category.
7 Reproductive toxicity Classification not possible - - - - No data available.
8 Specific target organ toxicity - Single exposure Category 3 (Respiratory tract irritation) Warning H335: May cause respiratory irritation (respiratory tract irritation) P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.
P403+P233: Store in a well-ventilated place. Keep container tightly closed.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P271: Use only outdoors or in a well-ventilated area.
P312: Call a POISON CENTER or doctor/physician if you feel unwell.
P405: Store locked up.
P501: Dispose of contents/container to ...
ACGIH established acceptable concentrations of this substance for the purpose of alleviating irritation of the respiratory system. In light of this report, the substance was classified into Category 3 (respiratory tract irritation).
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - Based on reports in various animal tests and epidemiological studies, the cause of respiratory disorder cannot be exclusively attributed to exposure to zirconium powder (metal) (DFGOT (vol. 12, 1999); Patty 5th (2005); ACGIH (7th, 2001); RTECS (accessed in July 2007)). Thus, the substance was classified into the "Classification not possible" category due to insufficient test results available.
10 Aspiration hazard Classification not possible - - - - No data available.
