NFPA-99 Practice Exam

Under what condition is the mechanical limitation of the makeup depth of a fitting permitted for medical gas piping installation?

1. Only on final line connectors.

2. Only on vacuum systems.

3. Where only B cup 5 brazing rod is used.

4. Where the limited makeup depth is not less than maximum cut depth per ANSI/ASME recommendations.

The correct answer is: Where the limited makeup depth is not less than maximum cut depth per ANSI/ASME recommendations.

In medical gas piping installations, it is essential to adhere to strict safety and performance standards, as these systems can have significant implications for patient care. The concept of makeup depth refers to how deep the fitting can be engaged within the pipe without compromising the integrity of the joint or the overall system. Choosing the option that indicates a limitation on makeup depth as not being less than the maximum cut depth per ANSI/ASME recommendations affirms the importance of maintaining structural integrity and preventing leaks. The ANSI/ASME standards outline best practices for the installation and maintenance of piping systems to ensure safe and effective performance. By ensuring that the limited makeup depth meets or exceeds these established recommendations, the fitting will maintain sufficient contact area and strength at the joint, which is crucial for the reliability of medical gas systems. This approach not only supports compliance with safety codes but also involves professional workmanship that protects patient safety. Each medical gas installation should follow these standards to prevent potential failure or hazardous situations that could arise from poorly made joints.
