Abstract: In figure 1 a section of fire rated duct 100 is shown which has been fabricated using a fire 
access panel system according to an embodiment of the invention. The duct includes a duct 
body 110 and a pre-existing air-tight non fire-rated access panel 130 which is affixed into an 
aperture in the duct body 110 by way of latches 132. A frame member in the form of frame 
10 has been attached to the duct body 110 using the preformed holes in the frame, to ensure 
adequate mechanical fixings. Duct wrap fire insulation material 120 has been wrapped 
around the duct body 110 and has been fitted into a recess in the frame about the periphery of 
the frame. A removable laminated fire rated access panel (not shown in figure 1) is to be 
fitted to frame 10 to complete the installation.
