    摘要: A collapsible containment berm having a floor and a peripheral sidewall, a plurality of brace assemblies integrally carried on an external surface of the sidewall and on an adjacent underside surface of the floor, each brace assembly comprising a rigid sidewall support member connected to the external surface of the sidewall and oriented upright when deployed, a rigid buttress member having a first end and an opposite second end, and hingedly connected to an upper end of the sidewall support member that allows the buttress member to arc toward or away from the sidewall, a rigid floor member hingedly connected at the third end to the other end of the buttress member, and a sleeve connected to the underside of the floor and adapted to receive the floor member. The floor member slides in and out of the sleeve and moves the buttress member in and out of a bracing position with respect to the sidewall.

    摘要: An overfill indicator for a flexible collapsible liquid storage tank made of a liquid impervious fabric and having a floor and a top wall with a vent therein, the overfill indicator comprising a connector portion adapted to removably connecting to the vent of the tank, an indicator movably mounted to the connector portion, the indicator being moveable between a resting position and a visually noticeable alert position, a base portion located on the inside of the tank and on the floor thereof and aligned with the vent, and a linkage connecting the base to the indicator such that the indicator is moved from the resting position to the alert position as the top wall of the tank reaches a threshold distance from the floor as the tank is filled with liquid, wherein said threshold distance coincides with the tank having reached a desired liquid capacity.
