In other words, how to safely exit a submerged submarine and get all the crew members to the surface without them getting the "bends". The students train at the Submarine Escape Training Tank (SETT), a 100-foot water tower either at the submarine base, Pearl Harbor, Hawaii or at the submarine base, New London, Connecticut. This is a film that all U.S. submariners watched at some point during their career. The film mainly focuses on how the safety appliance called the Steinke hood can be properly used to ensure safe escape from a submarine at depths of 450 ft or greater. Film opens, opening credits, introduction and film overview (0:07). Exterior view of SETT at Submarine Base Pearl Harbor, Hawaii (1:34). Exterior view of SETT at Submarine Base New London, Connecticut (1:44). Detailed information about training tanks: Contain 250,000 gallons of water, water maintained at 92 degrees F, filtered and recirculated every 7 hours (1:48). Structure of film, split into three parts: Explanation of the appliance, how it is worn, how it is used (2:08). Part 1: Explanation; Man wearing swim trunks demos Steinke hood for camera: Large buoyancy chamber, charging inlet-check valve for inflation, pocket for surface survival equipment, oral inflation tube, flashlight, zipper connecting hood to jacket, protection flap to prevent chafing, relief valves (2:25). Animated demo of how air is released through relief valves as wearer ascends (3:47). More features of Steinke hood such as zipper-attached hood, plastic window for visibility (4:41). Illustration of man wearing Steinke hood, demonstration of how hood creates dry chamber for the circulation of air (5:08). Snorkel valve assembly; How to operate and open ports of snorkel valve (5:23). Adjustable waist belt on lower portion of escape appliance (6:04). Demo of snap-hook line; Attached to ascending cable to guide trainee to surface (6:25). Part 2: How to wear appliance (6:36). Man from earlier demonstrates step-by-step how to put on appliance: Fasten waist belt, slip head through neck ring after taking and holding breath, check snorkel valve is closed, compressed air applied to buoyancy chamber (6:40). Animation of ascent while wearing Steinke hood, air escapes from buoyancy chamber and supplies hood with oxygen (7:23). Animation showing how breathing through the mouth allows for release of air with high carbon dioxide and intake of fresh air (8:22). Three positions escape appliance worn in during training procedures: Carry position (9:13). Stand-by position (9:47). Ascent position; trainee must keep feet together and head back, arms extended overhead with thumbs locked (10:25). Part 3: How escape appliance used during training tank procedures (11:11). Trainees enter escape lock with appliance in carry position, instructor assists in lock operation and shuts outer door (11:19). Another instructor opens water valve to flood tank (11:35). Tank filled, escape door opened, trainee puts on hood while instructor inflates buoyancy chamber (12:20). Animation detailing how to exit through escape door and ascend in main training chamber (13:47). Return to live action footage, multiple training ascents depicting active use of appliance and correct form (15:03). Instructor offers individual feedback after appliance deflated; Points out mistakes and offers corrective actions (17:04). After briefing, trainee takes position behind white line on deck with other trainees; Stand with weight evenly distributed and check for symptoms of rapid ascension (17:15). Two components of appliance not used in tank training: Zipper on neck, oral inflation tube (17:30). Young man demonstrates opening the neck of the hood with zipper after ascent at sea, use of oral inflation tube to maintain buoyancy while on surface (17:47). Closing words, summary of important points conveyed during film (18:15). Film ends (20:23). Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction.
