Chemsafe
Chemsafe (own name: CHEMSAFE ) is a free database for evaluated safety parameters of flammable chemical substances and mixtures, which is operated by the Physikalisch-Technische Bundesanstalt .
Until 2016, the database will be distributed via DECHEMA, which also sells an in-house version for larger companies.
content
The parameters
- Explosion limits
- Maximum explosion pressures
- Flashpoints
- Explosion points
- Ignition temperatures
- Minimum ignition energies
- Standard gap widths
- Stability limit pressures
are used for explosion and fire protection when handling (transport, filling, storage, disposal, etc.) of flammable chemical substances.
Besides this data, Chemsafe also contains
- Information on substance identification
- thermophysical data (e.g. boiling points, enthalpies of formation)
- Identification and classification according to national and international regulations
- maximum workplace concentration (MAK)
- bibliographic data
- Definitions and help texts for the parameters
Chemsafe also contains tools for the graphical representation of explosion areas, for example, and some calculation methods for determining the flammability, the oxidation potential, the vapor pressure and standard gap widths for mixtures.
use
Chemsafe serves as a database in
- international standards (e.g. IEC / TR 60079-20 "Data for flammable gases in vapors" and in future ISO 10156)
- national regulations (e.g. in the professional association rules BGR 104, BGR 132 and BGR 500, section gases, "table of decomposable gases")
- other databases (e.g. BAM dangerous goods database , joint central substance data pool of the federal and state governments )
and as a basis for tables (e.g. Nabert / Schön / Redeker and "Safety-related parameters" Volumes 1 and 2 from PTB and BAM) and the creation of EC safety data sheets.
Database structure
Chemsafe is used by federal agencies
- PTB ( Physikalisch-Technische Bundesanstalt , Braunschweig)
- BAM ( Federal Institute for Materials Research and Testing , Berlin)
maintained, whereby the PTB contributes data for liquids and the BAM data for gases and dusts. Sources are own measurements and evaluated data from freely accessible literature.
