The vacuum exhaust shall not discharge __________.

• A. In a place of public assembly
• B. At a different level from air intakes
• C. Outside
• D. On a roof

Answer: (A)

The important idea here is keeping exhaust air from a medical vacuum system away from places where people gather. Vacuum exhaust can carry odors or potentially contaminated air from suctioned materials, so it’s critical to vent it to a location where occupants won’t be exposed or breathing it in.

That’s why the best choice is that the vacuum exhaust should not discharge into a place of public assembly. Exposing patients, staff, or visitors to any discharge from the vacuum line would pose a risk of contamination or nuisance odors in areas where people spend time.

In practice, exhausts are routed to the outdoors or up to a roof, and they are positioned to stay clear of air intakes and occupied spaces. Placing the discharge outside or on a roof is common, provided it’s arranged so the air doesn’t re-enter the building or affect locations where people gather. Discharging at a different level from air intakes is also a typical design consideration to minimize backflow and re-entrainment.
