At the MOHAWK PETROLEUM DIVISION of Getty Oil Company in Bakersfield, California, Marinite I fireproof structural insulation panels are the major element in a simply designed cable raceway.

Marinite I makes simply detailed fire-resistant cable raceways.

In a new gas oil desulfurizer, built as part of a major modernization and expansion of the Bakersfield facility, the wiring for all instrumentation passes through the process equipment of this unit. In case of fire, catastrophic failures could occur if the wire was affected.
To protect the wiring from such an occurrence, several systems were evaluated, including a flame-proof mastic over an
expanded metal enclosure and a refractory fiber board enclosure. The former system had been used in the past and proved to be too labor intensive, while the latter was neither structurally suitable nor sufficiently weather resistant.
The system which evolved and which was used successfully was designed by Thomas R. Puckelwartz and Associates, of Arlington Heights, Illinois, construction managers for the expansion.

The cables were first enclosed in rigid steel conduit.
A simple steel frame of 11⁄2″ x 11⁄2″ x 1⁄4″ steel angle surrounds the conduit and acts as a supporting frame. Sheets of 1″ thick Marinite I panels were used to enclose the raceway which is approximately 3 feet square. The panels were fastened to the longitudinal angles with self-threading screws and washers.
No backup structure was needed at the joints between the Marinite boards.
The Marinite I panels, made of calcium silicate were first given a coat of Devguard™ 4160 or LOXON® conditioner and then finished with Devflex™ 4216HP or DTM Acrylic Coating.
At the ends of the cable raceways, the spaces between conduits and those between conduits and the Marinite sheathing were packed with

a lightweight, mastic, fireproofing material. This prevents the ducting of flame along the inside of the fire-resistant raceway.
This raceway system has withstood both weather and unanticipated foot traffic with no problems, and the system has since been used in the expansion of an adjacent refinery.
Marinite fireproof structural insulating panels have many applications throughout a broad range of industry.
