Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Flammability: Extremely Flammable Gas. Contact with water may release flammable gas.
Key value for chemical safety assessment
- Flammability:
- extremely flammable
Additional information
No flammability study is available for the substance. However, sufficient evidence is available to allow the substance to be classified as an Extremely Flammable Gas and further testing is not considered necessary.
There is no evidence from experience in handling and use that the substance is flammable in contact with air. In contact with water, the flammable gas hydrogen may be produced.
Justification for classification or non-classification
The substance is classified as follows:
According to Regulation (EC) No 1272/2008:
- Flam. Gas 1. H220: Extremely flammable gas.
- Water React. Flam. Gas 3. H261: In contact with water releases flammable gases.
According to Directive 67/548/EEC:
F+; R12 Extremely flammable; Extremely flammable.
F; R14/15 Highly flammable; Reacts violently with water, liberating extremely flammable gases.
The classification of extremely flammable is on the basis of a flash point of 9°C and a boiling point of 6°C, supported by evidence for close structural analogues of the substance.
The presence of the Si-H bond in the molecule indicates that contact with water may result in release of hydrogen, a flammable gas.
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.
