A Draeger gas detector tube indicates the presence of Carbon Monoxide. How many times can the same tube be reused?

• A. Once
• B. Twice
• C. Three times
• D. Unlimited

Answer: (A)

Draeger gas detector tubes are designed for single-use only. When a tube indicates the presence of a gas such as Carbon Monoxide, it undergoes a chemical reaction that is irreversible. This reaction changes the physical characteristics of the material inside the tube, which can lead to inaccurate readings if the tube is reused.

Using a gas detector tube more than once could lead to misleading results, making it crucial to adhere to the manufacturer's guidelines for single-use to ensure safety and compliance in monitoring hazardous gases. Therefore, the correct answer signifies the importance of proper usage of detection equipment in maintaining accuracy and safety in potentially dangerous environments.
