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 allows the storage of own data together with the recommended data of BAM and PTB. Due to the realization as a client-server application, all users in your company can therefore access the same database.

The Online solution

PTB is offering a free of chargeOnline Access for the complete CHEMSAFE database.
