ABSTRACT:
A pressure vessel safety relief includes one or more recesses on a bottom wall section of the vessel. The thickness of the bottom wall section in areas directly over each recess is less than the thickness of remaining areas of the bottom wall section. Once the bottom wall section has corroded to a significant degree, the wall section ruptures in areas over the recesses to safely relieve pressure within the vessel. Preferably, the recess decreases in cross-sectional area as the top of the recess is approached, such that the escaping air emits a high-pitched whistling noise that functions as an alarm to notify the user that the vessel is corroded and should be replaced.
