TY - GEN A1 - Molnarne, Maria T1 - Determination of Fire and Explosion Hazards of Dusts, Vapours, Gases and their Mixtures according to the EC Directives by using the Database CHEMSAFE T2 - 1st Italian Convention on Safety & Environment in Process Industry N2 - According to the European Occupation Safety and Health guideline (especially the EC hazardous materials directive 98/24/EC on the protection of the health and safety of workers from the risks related to chemical agents at work) the employer is obliged to identify and evaluate the risk on exposure to dangerous substances at the working place. For this purpose they need reliable, easily available and evaluated data by expert to estimate the risk not only on toxicity but also on fire and explosion. This contribution will show the use of the database CHEMSAFE to search for substances and their mixtures which have hazardous physico-chemical properties and safety characteristics for fire and explosion. The database include more than 3000 substances in 57000 data tables. Safety characteristics like explosion range for more than 200 gas mixtures up to 100 bar and 400 °C are an important part of it. It will be also demonstrated how one can avoid the explosive atmospheres using the measure inerting and for this purpose the necessary data, for e. g. limiting oxygen concentration, can be taken from this database. Also estimation methods for classification of gas mixtures for flammability are included in CHEMSAFE. On the same time the audience will be encouraged to cooperate in order to extend the database with data measured by other institutions or the field of application of the database for example with additional data such as DSC, SADT or other data concerning thermal stability and calorimetry.Cooperation is also possible for developing estimation and calculation methods on the basis of this evaluated database.
