When cable trays pass through walls from a normal environment into a fireproof or explosion-proof environment, appropriate sealing devices should be installed on the wall. It can also help to keep out birds, rodents and insects. Fire. Vertical penetrations are weathertight openings where pipes, ducts, cable trays and any other building ancillaries enter or exit a building through a wall. They provide a route for building services such as gas, water, and electricity to enter a building, for waste to be carried away and for data. This document outlines the key requirements for cable tray layout, installation, and fireproofing in industrial and commercial environments. The answer is yes, but with a caveat: only when robust waterproofing measures are implemented. Safeguarding outdoor cable trays is not just a.
