At least the front side of the placard card includes information about an identity of a dangerous material. For example, the front side of the placard card may include indicia indicative of the specific identity of the dangerous material or a particular warning about the particular danger posed by the dangerous material (e.g. flammable or corrosive, or visuals symbols indicating the same).

[0051] Referring now to FIG. 1, illustrated therein is a placard holder 100 according to one embodiment. Placard holder 100 includes a holder portion 102 movably coupled to a backing plate 104. Placard holder 100 also includes a fastener 112 engaged with (e.g. coupled or affixed to) the backing plate 104 and configured to secure at least a portion of the holder portion 102 to the backing plate 104 to retain at least one placard card in pocket 106 (see FIG. 2). For instance, as shown in the embodiment in FIG. 1, the fastener 112 is configured to secure a top end 114 (opening 108) of the holder portion 102 to the backing plate 104.

[0052] Referring now to FIGS. 2 and 3, holder portion 102 includes an opening 108 and a pocket 106 extending away from opening 108 for receiving a placard card. Pocket 106 and opening 108 are sized and shaped to receive and retain at least one placard card therein.

[0053] Returning to FIG. 1, the holder portion 102 is hingedly coupled to the backing plate 104 on one side or end by a hinge 110. Hinge 110 is coupled to the holder portion 102 at a position spaced from the opening 108 to provide for a user to insert a placard card into the pocket 106 via the opening 108 without interference from the hinge 110. For instance, in the embodiment shown in the Figures, the hinge 110 is positioned at a bottom end 118 of the holder portion 102. Specifically, in the embodiment shown in the Figures, hinge 110 is affixed (e.g. riveted) to a bottom edge 120 of the holder portion 102. It should be understood that the hinge 110 can be coupled to the holder portion 102 in any appropriate manner that secures the hinge 110 to the holder portion 102, such as but not limited to being riveted to the holder portion 102 using one or more rivets.

[0054] Holder portion 102 may be square-shaped or substantially square-shaped (e.g. may have rounded corners) and may be planar or substantially planar. Holder portion 102 may include a plurality of windows 116 sized to provide for a placard card retained in the pocket 106 to be viewable while looking at a front view of the placard holder 100. Pocket 106 is positioned rearwardly of a front surface 122 of the holder portion 102 and forward of a front face 124 of the backing plate 104.

[0055] In the embodiment shown in the Figures, hinge 110 is coupled to the backing plate 104 at a position spaced from fastener 112 to provide for a user to insert a placard card into the pocket 106 via the opening 108 without interference from the fastener 112 when the placard holder is in its open position. For instance, in the embodiment shown in the Figures, the hinge 110 is positioned at a bottom end 126 of the backing plate 104. Specifically, in the embodiment shown in the Figures, hinge 110 is affixed (e.g. riveted) to a bottom edge 126 of the backing plate 104. It should be understood that the hinge 110 can be coupled to the backing plate 104 in any appropriate manner that secures the hinge 110 to the backing plate 104, such as but not limited to being riveted to the backing plate 104 using one or more rivets.

[0056] Backing plate 104 is also generally square-shaped or substantially square-shaped (e.g. may have rounded corners) and planar or substantially planar (e.g. may have minor indentations or protrusions). Backing plate 104 may also include a plurality of fasteners (not shown) to secure the placard holder 100 to a transportation container (not shown).

[0057] Turning now to FIG. 4, shown therein is a rear view of the backing plate 104 showing rear surface 130. Backing plate 104 may include a plurality of protrusions 134 extending outwardly from the backing plate 104 (i.e. from a front surface thereof) towards the holder portion 102 and a placard card retained therein. Protrusions 134 may inhibit a placard card retained in the holder portion 102 from sticking to the backing plate 104. Protrusions 134 may also push the placard card towards the holder portion 102 to inhibit movement of the placard card when retained in the holder portion 102.

[0058] An example embodiment of a hinge 110 is shown in FIGS. 5-7. Hinge 110 can be any movable joint or mechanism on which holder portion 102 rotates or swings as holder portion 102 moves between its open and closed positions and which couples holder portion 102 to backing plate 104. In the embodiment shown, hinge 110 includes a first plate portion 136, a second plate portion 138 and a pin 140 therebetween. First plate 136 is coupled (e.g. affixed by rivets) to the holder portion 102 and the second plate portion 138 is coupled (e.g. affixed by rivets) to the backing plate 104. A portion of first plate portion 136 and second plate portion 138 wrap around pin 140 to provide for first plate portion 136 and second plate portion 138 to rotate about the pin 140. In at least one embodiment, hinge 110 provides for holder portion to rotate at least one 180 degrees to provide for a user to insert a placard card into the holder portion.

[0059] FIG. 8 shows an exemplary embodiment of holder portion 102. FIG. 8 shows that pocket 106 is defined by a plurality of folds 150 of the holder portion 102. Folds 150 are extensions of a frame 152 of the holder portion 102 that fold rearwardly from the front surface 122 of the holder portion 102 to provide a spacing to define the pocket 106. The spacing can be configured to retain a placard card therein. One or more of the folds 150 may extend along each of first side 154 and second side 156 of the holder portion 102 and one or more folds 150 may extend along a bottom edge 120 of the holder portion 102.

[0060] FIG. 9A shows a side view of the holder portion 102 of FIG. 1. FIG. 9B shows that, in at least one embodiment, the folds 150 are continuous with front surface 122 of the holder portion 102. Folds 150 may be sized to define a spacing S appropriate for retaining a placard card therein. In some embodiments, spacing S is sized to retain more than one placard card, such as but not limited to three or four or five placard cards. For instance, spacing S may be in a range of about 0.1 inches to about 2 inches, or in a range of about 0.1 to about 1 inch. In at least one embodiment, placard cards not being used to identify the dangerous goods of the container upon which the placard holder is attached can be stored in the holder portion 102.

[0061] In some embodiments, adjacent folds 150 may be spaced apart from each other by a gap G sized to provide for drainage of water from between the backing plate 104 and the holder portion 102.

[0062] Referring now to FIG. 10, illustrated therein is a method 1000 of securing a placard card in a placard holder.

[0063] To secure the placard in the holder portion 102, an operator grasps the holder portion 102 and rotates the holder portion 102 outwardly relative to the backing plate 104 about the hinge 110. When the holder portion 102 is sufficiently spaced from the fastener 112, the opening 108 is exposed and, at step 1002, the operator can insert the placard card into the pocket 106 defined by the holder portion 102 via the opening 108.

[0064] Once the placard card is received in the pocket 106, the operator can secure the placard card in the holder portion 102 by, at step 1004, returning the holder portion 102 to its closed position by rotating the holder portion 102 towards the backing plate 104 about the hinge 110. When the holder portion 102 approaches the backing plate 104, at step 1006, the fastener can be manipulated to secure the holder portion 102 to the backing plate 104 to retain the placard card in the holder portion 102.

[0065] The placard holders described herein can be secured to a transportation container (not shown), such as but not limited to a truck, an intermodal container (e.g. a trailer), a railcar, a storage tank or the like or any similar container not used in transportation. The placard holders may be secured to the transportation container by fasteners such as rivets or bolts or by an adhesive affixed to a rear surface (not shown) of the placard holders.
