Abstract
An improved safety pressure relief system for volatile liquid storage tanks is provided. A pressure relief valve is connected to the storage tank so that when the pressure within the storage tank reaches a predetermined high level, vapors are vented therefrom by way of the outlet of the relief valve. A container for containing pressurized vapors having an inlet and a closed outlet is provided, and conduit means are connected between the relief valve outlet and the inlet of the container for conducting vapors vented by the relief valve to within the container. Means for indicating the presence of vapors within the container are attached thereto.
