NFPA-99 Practice Exam

What must be true about vacuum piping connections to a receiving tank?

1. They can share connections with medical surgical systems

2. Must be connected to the receiver via its own isolation valve

3. They do not need to be isolated

4. They can bypass the fluid trap

The correct answer is: Must be connected to the receiver via its own isolation valve

The requirement that vacuum piping connections to a receiving tank must be connected via their own isolation valve is essential for several reasons. Isolation valves serve as a means to control the flow of substances in the piping system. By having an isolation valve specifically for the vacuum connections, you can safely shut off the vacuum system in the event of a leak or when maintenance is required, ensuring that no contaminants escape into the environment or the supply lines. Furthermore, having dedicated isolation allows for better system management and helps maintain the integrity of the vacuum system. It ensures that the vacuum system can operate independently, reducing the risk of interference or contamination from other systems. This practice aligns with safety and regulatory standards outlined in NFPA regulations, which aim to ensure that all medical gas systems, including vacuum systems, function safely and effectively without cross-contamination or other hazards. In contrast, the other options either introduce potential risks or defy established safety protocols within medical environments.
