The 4500 psi manifold cascade system, consisting of six “K” bottles, a pressure control valve, pressure gauges and two fill whips, was recharged at the Florida State University’s Academic Diving Program facility located 45 miles distant on the Tallahassee Campus. Cascade system recharging and scuba tank-filling were performed only by individuals who had been checked out on such procedures by divemaster staff. All Department of Transportation safety regulations were followed whenever the cascade system was transported on public roads.
