# §153.365. Liquid overpressurization protection.

- (a) Except as noted in [paragraph (b)](#b) of this section, a containment system requiring closed or restricted gauging must:
  - (1) Be designed to withstand the maximum pressure that develops during an overfill of the densest cargo endorsed for the containment system; or
  - (2) Have an overflow control system that meets [§ 153.408](/cfr/46/153.408.md); or
  - (3) **Meet the requirements specified by the Commandant (CG-ENG).**
- (b) A containment system requiring restricted gauging, except for those cargoes that reference §§ [153.525](/cfr/46/153.525.md) or [153.527](/cfr/46/153.527.md), may be equipped with a spill valve that:
  - (1) Meets ASTM F 1271 (incorporated by reference, see [§ 153.4](/cfr/46/153.4.md)); and
  - (2) Limits the maximum pressure during liquid overfill at a specified cargo loading rate to that which the containment system is able to withstand (see §§ [153.294(b)](/cfr/46/153.294.md?p=b) and [152.977(b)](/cfr/46/152.977.md?p=b)).
