Abstract: A security device protects the vulnerable portions or accessories of a bulk storage tank or container against unauthorized access. The device includes a housing that covers the vulnerable portions of the tank, the housing having two or more lockable doors that selectively permit access to the tank or container via two or more respective apertures. A first door is openable after unlocking a readily-accessible lock, while the second movable door is openable after an elongate lock member that is positioned internally within the housing is moved to an unlocking position. The elongate lock member can be moved to its unlocking position after the first door is opened. Certain tank operations, such as dispensing fuel, may be carried out after unlocking and opening a single door, while other operations, such as refilling the tank, may be accomplished after opening a second door once the first door has been opened.

Abstract: Disclosed are apparatus and methodology for securing access to an underground device such as a storage tank. A lockable blocking plate is secured to a filler cap for an underground storage tank in a manner to inhibit access to the filler cap. The locking mechanism is configured such that the lock and blocking plate may freely rotate with respect to the filler cap. The blocking plate may include a side skirt extending to cover portions of the filler cap and, optionally, portions of a standpipe and coupling for the filler cap. Free rotation is enabled by way of an annular groove in a portion of the locking mechanism, and into which groove one or more locking portions may be inserted, or by way of a freely moving swivel boss attached to the filler cap.

Abstract: The invention relates to a compressed gas container (10?) comprising a block flange (14) that is provided on an upper opening in its wall (12), a flange cover (15) that is equipped with two extraction valves (22) being screwed onto said flange. The block flange (14) is extended radially beyond the region covered by the flange cover (15) by a solid annular flange (40), whose outer periphery is welded to the wall (12) of the container (10?) and whose inner section lying adjacent to the region covered by the flange cover comprises a peripheral groove (44) in an upper front face (42), for holding the sealing rib (46) of an emergency cap. If required, said cap can be screwed onto the annular flange (40) if a leak occurs in the flange region of the container (10?).

Abstract: A device for prevention of particulate contamination of a valve fitting and for notification of whether actual access or tampering or potential access or tampering of a fluid from a fluid tank connected to the valve and/or the valve has occurred, featuring a fitting block which is insertable within the fitting or capable of receiving the fitting, and first and second straps bendable about the valve and fastenable to each other. One of the straps may include a ring through which a valve burst disk is insertable when the strap is bent about the valve. If the device was compromised and the cylinder was removed for access to the valve fitting, the ring of one of the straps would remain on the burst disk even though the cylinder was removed from the fitting. Thus, the compromised device would remain on the valve indicating that access to the valve or fluid had been attempted or achieved.
