• A. To hold the tube securely
• B. To indicate the gas type
• C. To record data concerning the test taken
• D. To ensure user safety

Answer: (C)

The main purpose of the band on the upper end of a Draeger Tube is to record data concerning the test taken. This band often includes important information such as the type of gas the tube is designed to measure and may also indicate expiration dates or batch numbers. Keeping accurate records of testing is essential in hazardous environments to ensure that the data collected can be trusted and used effectively. The presence of this band enhances the reliability of the testing process by documenting vital details about each specific tube's use, allowing operators to maintain safety protocols and comply with regulatory requirements.

The other options, while related to the functionality of the Draeger Tube, do not accurately describe the primary role of the band. For instance, while securing the tube or ensuring user safety are important aspects of utilizing such equipment, it is the band specifically that serves the purpose of data recording.
