The E90 fire resistance grade ensure the electrical system such as emergency lighting, ventilators, emergency exit, fire alarm, etc can remain working properly and resist long enough to provide assistance in the event of a fire. What's more the compeletely open design of wire mesh cable trays would make sure smoke detectors and fire sprinklers would not be blocked.
