Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Preliminary test:

The test item could not be ignited with a flame. The performance of the main test was therefore not necessary.

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The test item could not be ignited with a flame in the preliminary test. The performance of the main test was therefore not necessary.

Description of key information

Arsenic metal (powder, ca. 0.1-1mm size range) was not flammable in a study according to EU method A.10, where an attempt was made to ignite a pile of the metal powder with a flame. The pile could not be ignited. In a study for self-ignition (heating to ca. 400°C), no self-ignition of arsenic metal has been observed. Further, arsenic metal dose not react with water under formation of flammable gases. In contrast, arsenic metal has a very low water solubility and yields only dissolved inorganic ions upon dissolution.

Additional information

Justification for classification or non-classification

 Arsenic metal (powder, ca. 0.1-1mm size range) was not flammable in a study according to EU method A.10, where an attempt was made to ignite a pile of the metal powder with a flame. The pile could not be ignited. In a study for self-ignition (heating to ca. 400°C), no self-ignition of arsenic metal has been observed. Further, arsenic metal dose not react with water under formation of flammable gases. In contract, arsenic metal has a very low water solubility and yields only dissolved inorganic ions upon dissolution. In conclusion, a classification for flammability is not required for alfa arsenic metal.
