Synopsis

Made in 1943 for the U.S. Navy, "Damage Control IV" shows the use of the Rescue Breathing Apparatus during firefighting operations aboard ships. Shown is the Navy Oxygen Breathing Rescue Apparatus, Type A-1, a self-contained, closed-circuit device. Oxygen, generated by chemicals in a canister, flowed to the right-hand section of the breathing bag, where it mixed with air previously passed through the canister, then to the left-hand breathing bag and on through the inhalation tube into the lungs. This process allowed the wearer to be independent of the surrounding atmosphere for the effective time limit of the oxygen supply, approximately 45 minutes. This film provides a detailed explanation of the use and operation of rescue breather apparatus designed for firefighting in confined, smoke-filled spaces. It describes the importance of these devices in allowing wearers to breathe safely in atmospheres with reduced oxygen or contaminated air, such as during fires below decks. The apparatus works by absorbing carbon dioxide and releasing oxygen through a chemical reaction. The text outlines three types of breather apparatus (Type A, Type A1, and patrol type), their components, and how to properly adjust and wear them. It also emphasizes the need for regular maintenance, airtight fittings, and testing to ensure the equipment is ready for use in emergencies. Additionally, safety precautions for handling and disposing of used canisters are highlighted to prevent hazardous reactions.…
