Flammable vapours and gases are handled in many industries and the danger of explosion exists wherever these vapours and gases may form flammable mixtures with air. A common way of protecting plant and buildings against explosions is to provide relief vents. In this note, certain aspects of the design and installation of these vents are discussed. Although no attempt is made to give a comprehensive review of the subject or to give a practical guide to venting, particular attention is paid to the correlation of the results of different investigations, to indicating those problems for which useful information is available and those for which further work is still required.
