Hazards of cable tray cover plates
Improperly secured covers on outdoor cable trays can cause a serious hazard in harsh environment conditions such as wind, snow, and ice. Below, we analyze the common cable tray safety hazards and discuss how each risk can be mitigated to ensure optimal safety and functionality. Customers with experience with “raceways” tend to lean towards requiring. Safety of a cable tray is not a matter of compliance with codes, but a matter of saving human life and billions of dollars' worth of infrastructure. Poorly fitted trays may serve as a fuse in case of a short or a top chimney in case of a fire. This issue can lead to potential injury, equipment damage, or service disruptions.
