Abstract: Described is a containment device for holding a container that defines a container interior volume. The containment device can include a base portion enclosing a base portion interior volume, the base portion including: a plurality of base walls, a trough extending from at least one of the base walls, and a substantially horizontal support surface adapted to support the container above the base portion interior volume. The base portion interior volume can be equal to or greater than the container interior volume. An enclosure can extend above the base portion, the enclosure including a plurality of enclosure walls adapted to surround the container. The enclosure walls can define an opening above the trough, the opening adapted for insertion of the container into the enclosure.

Abstract: A radiation-activated sprinkler includes a sprinkler body defining a main orifice, the main orifice adapted to couple to a source of pressurized liquid; a deflector coupled to the body; a valve adapted to seat on the main orifice to block the source of pressurized liquid; a linkage mechanism adapted to retain the valve on the main orifice; and one or more fusible links coupled to the linkage mechanism, wherein the one or more fusible links are located substantially externally with respect to the sprinkler body, deflector, and linkage mechanism. The one or more fusible links are adapted to release when exposed to an amount of radiation that exceeds a predetermined threshold, thereby releasing the linkage mechanism from the valve. Other features and related methods are also described.
