Abstract: The present invention relates to a barrier assembly for use in protection of personnel at worksites and/or residential areas from escapes of gas. More particularly, this invention relates to a barrier assembly for controlling the lateral and vertical spread of gas in the event of an escape of said gas, even more particularly toxic gas. The invention finds application in all operating sites where gases are produced, and in particular where high concentrations of toxic gases (e.g. CO 2 , H 2 S, SO 2 , mercaptans etc) are present, optionally acting as a safety system in the event of an accidental uncontrolled release of these toxic gases into the atmosphere.
