The numerical database Chemsafe contains assessed safety parameters and properties for more than 3000 flammable liquids, gases and dusts.

The Problem: Reliable Data

Safety parameters of fire and explosion prevention are essential for assessment of hazards while processing, filling, storing, transporting or disposing flammable substances. Users in trade and industry need reliable parameters recommended by experts. These data must always be up to date and rapidly available.

The Solution: CHEMSAFE

The database, which is online since 1989, is a joint project between

  • PTB - Physikalisch-Technische Bundesanstalt, Braunschweig
  • BAM - Bundesanstalt für Materialforschung und -prüfung, Berlin
  • DECHEMA e.V., Frankfurt am Main

The Data Providers: BAM und PTB

Sources of the data are own measurements and data compiled from the literature by the laboratories of BAM and PTB, which are specialized on assessing physico-chemical hazards of flammable gases, dusts (BAM), and liquids (PTB). The gathered data are checked in respect of their reliability, rated and stored in the data collection.

The Data: Characteristics and more

Actually CHEMSAFE contains assessed safety parameters for more than 3000 flammable liquids, gases and dusts, e.g.:

  • flash point
  • autoignition temperature
  • explosion limits
  • minimum ignition energy
  • maximum experimental safe gap
  • labelling and classification according to national and international regulations
  • maximum explosion pressure
  • maximum pressure rise
  • ignition temperature of a dust layer
  • smoldering point
  • minimum decomposition pressure
  • maximum working place concentration (MAK)

The Inhouse solution

The Inhouse-Version of CHEMSAFE allows a quick and successful access to the database especially for the unexperienced user. An outstanding feature is the possibility to plot the data  - for example the explosion range of mixture CO/water/air at different temperatures.

CHEMSAFE Inhouse is available in two different versions:

  • CHEMSAFE-ORS is based on an ORACLE database and is designed for Client-Server usage. This version of CHEMSAFE contains together with the recommended data the data of the secondary literature.
  • CHEMSAFE-Lite is a single user version runing directly from CD-ROM. This version of the database contains only the recommended values. It is not possible to enter own data. CHEMSAFE-Lite is recommended especially for occasional users.

The Online solution

Our Internet solution Chemsafe ... on the WEB allows direct access to the complete CHEMSAFE database simply from your web browser. Searching the database and displaying basic information is free of charge.  Access to the numerical data sets itself is possible for registered users on a pay-per-view basis. The prices for downloading data depend on the size of the data table. They are announced online while searching.
