Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
OBSH with a purity of more than 90% (91-97%) was found to be sensitive to shock using a fall weigth of 10 kg and a fall heigth of 40 cm, corresponding to 40 J, and with a fall weigth of 5 kg and fall heigth of 15 cm (25 J). OBSH of a purity of 80-85% was found not to be explosive, due to treatment by shock, friction or ignition.
Key value for chemical safety assessment
- Explosiveness:
- explosive
Additional information
OBSH of 91 to 97% purity was found to be explosive when shock treated by fall hammer of 5 and 10 kg with fall heigth of 15 and 40 cm. Explosivity was observed more often when OBSH was treated with 10 kg fall weigth compared to 5 kg. Additionally, OBSH of purity lower than 90% was found not to be explosive, when shock treated by fall hammer, friction, or flame source.
Justification for classification or non-classification
The substance does not need to be classified as explosive, because OBSH is classified as a self-reactive substance Type D.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
