Can a person walk on an installed Cable Tray System?

No; walking on cable trays is not to be permitted. It violates the new version of NEMA standard VE-2, manufacturers marking and recommendations, and the intent of the NFPA70 Electrical Safety in Employee Work Practices. Walking on electrical equipment, conduits, cables or other electrical systems should also be avoided. In addition to the fall hazard, there is the risk of damage to equipment and possible contact with conductors.
