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.

00:00 -1:35 – Discussion of the challenges of firefighting below decks, including smoke, carbon monoxide, and limited oxygen. Military gas masks can filter smoke but don’t supply oxygen, requiring specialized breather apparatus for safety.

1:36-3:45 – Description of three types of breather apparatus (Type A, A1, and patrol type), all designed to filter out carbon dioxide and provide oxygen. The apparatus makes the wearer independent of the surrounding atmosphere, allowing them to breathe safely in hazardous conditions.

3:46-6:10 – Explanation of how the apparatus works: it uses a chemical canister to absorb carbon dioxide and release oxygen. The inhalation and exhalation valves control airflow, and the facepiece ensures an airtight seal.

6:11-7:40 – Step-by-step instructions on how to adjust and wear the apparatus properly for maximum comfort and safety, including how to check for an airtight fit.

7:41-9:02 – Instructions on using the breather in a fire scenario, including setting the timer for the canister’s one-hour life, and how to manage the air pressure and valve.

9:03-12:16 – Detailed process of activating the breather, including removing the outer seal from the canister, putting on the facepiece, and taking the required 15 starting breaths to start the chemical oxygen reaction. Instructions for safety and proper setup of the apparatus.

12:17-14:00 – Instructions for handling the canister after use, including removal and proper disposal, emphasizing the dangers of improperly discarded canisters.

14:01-16:06 – Describes the patrol type breather and its unique design features, like the hand wheel and bail system for inserting the canister.

16:07-19:00 – The Type A1 apparatus, combining features of both Type A and patrol types, and how to operate it. Emphasis on the importance of regular maintenance and proper fitting.

19:01-20:26 – Recap of key safety measures for all types of rescue breathers: the importance of airtight seals, proper maintenance, and performing the 15 starting breaths to ensure the apparatus functions for the full one-hour duration.
