				Conditions.

 


READILY
				ACCESSIBLE: Capable of being quickly obtained for operation
				without requiring removal of obstacles.

 


On

PRIMARY
				BUOYANCY CHAMBER: Any buoyancy chamber which independently
				provides sufficient buoyancy (at Minimum Operating Pressure) to
				achieve the minimum required freeboard around the entire
				periphery of the life raft with the life raft loaded at both
				rated and overload capacity. A minimum of two primary buoyancy
				chambers are required.
