Apparatus includes a lid and a containerlid combination, in which the interface between the lid and container provides a liquid-tight seal without the need for a separate gasket member or device. The LAN interface includes a link pulse detector 16 that operates on a predetermined voltage supplied via the IO bus 11 and detects a link pulse transmitted from a counter device connected to the connection port 15. In one example, the system includes a controller coupled to the strobe circuit and configured to assess the results and localize the damage based on measured changes in impedance of individual wires within the detection mesh. , crystalline boehmite, and a swellable clay component, e.
