An improvement in a tank for storage of a product or material at superatmospheric pressure which effects internal pressure relief, and thereby prevents the tank from rising off the foundation, when the anchor means is subjected to heat which causes failure of, or a serious loss of strength in, all or part of the anchor means. A thermally responsive sensor means is positioned in proximity to means anchoring the tank to the foundation. A pressure relief valve is mounted on the tank communicating with the interior thereof. Application of heat to the thermally responsive sensor actuates means to open the pressure relief valve and thereby reduce the pressure therein. With the pressure thus reduced the tank remains on the foundation even when the anchor means fails. |
