| The Navy provided a woven steel wire life-line for 
						use by firefighters. The uses of the line were numerous; 
						while most of them were precautionary, firefighters 
						often had to rescue a person that had been overcome by 
						smoke or had slipped, fallen and was injured. The rescue 
						was affected with the life-line as a means of hauling 
						the injured person to safety. The life-line was 
						indispensable for hauling a stricken person from a 
						compartment, lowering a rescue party or equipment into a 
						compartment and various other uses. The life-line was 
						also used in shallow water diving. The life-line was 50 
						feet long by 3/16 inch in diameter, which was later 
						changed to 3/8 inch in diameter. Each end had a stout 
						steel snap hook for attaching to the “D” ring on the OBA 
						or air-line harness. The line had maximum pliability and 
						would slide freely around obstructions. The life-line 
						was never secured around or to the waist. The life-line 
						was attached to firefighters involved in tasks where 
						they had to take more than ordinary risks. It was manned 
						by a fellow shipmate who knew the emergency signals -- 
						OATH -- so as to communicate with the wearer of the OBA 
						or shallow water breathing apparatus. He would pay out 
						the line off the coil with caution as tension was 
						created; he then slackened the line, being careful not 
						to allow it to become entangled. The following is the 
						tending line code for OBA/diver emergency signals. |
