Cable trays allow fire pipes
Install fire barriers within the tray to isolate different fire zones. When cable trays pass through walls or floors, seal openings using fire-rated penetration sealing materials. At slab penetrations, provide 20–30 mm of firestopping and install a fire-support plate at the top. Sealing shall be tight and reliable, without visible cracks or voids. * Two (2) sticks of moldable putty (part number FSP-MPS) are also needed for each opening. However, the cable tray may be centered directly below some. Cable tray systems help organize and support electrical cables efficiently, but improper installation or maintenance can increase the risk of electrical fires. Understanding proper cable tray fire safety practices is essential for protecting buildings, equipment, and occupants.
