Predicting vapor cloud explosions in enclosed spaces

For the example of 80 organic solvents, the methods developed by the All-Russian Research Institute for Fire Protection (ARIFP) and the Dutch ME-TNO method for vapor cloud explosions (VCE) in enclosed spaces are compared. The comparison focuses on the safe volume of the building. The correlation between the results of the two methods is established. After introducing a correction factor of 1.42, the METNO method for third-class VCE may be used to categorize production buildings in terms of explosion safety.
