During the time the St Julien [Hotel and Spa] was under construction, the fire marshal indicated additional exit signs were needed. The subcontractor working as the intermediary service provider was Riviera Electric. They ordered 3 tritium exit signs to be used on the property. After several discussions, it was determined the tritium exit signs posed a hazard and liability issues. The final decision was not to install them on the property. The disposition of the 3 tritium exit signs is unknown. They are being reported as lost. Riviera Electric is no longer in business.
