Vacuum piping for a teaching laboratory shall connect to what directly?

Vacuum piping in a teaching laboratory is designed to connect directly to a receiver tank. The receiver tank serves as a reservoir for the vacuum system, allowing for the collection and containment of materials or gases that are removed from the laboratory environment. This setup ensures the efficient operation of the vacuum system while providing a safe and controlled way to handle potentially hazardous materials.

Connecting directly to a receiver tank is critical because it is specifically designed to manage the vacuum pressure and to accommodate the substances being evacuated from the laboratory. The receiver tank typically has the necessary safety features, such as pressure relief mechanisms, to prevent overpressure conditions.

While a central vacuum system plays a significant role in providing overall vacuum capabilities to multiple locations or processes, it does not serve the same function as a dedicated receiver tank that is meant to handle specific evacuated materials in a teaching lab setting. Other options such as medical surgical systems and gas cylinders are not pertinent to the functions of vacuum systems and would not provide the necessary protections and controls required for laboratory operations.
