KNIGHTDALE, N.C. (WTVD) — Workers and animals at Wake Veterinary Hospital & Urgent Care had to evacuate the building Monday due to a carbon monoxide poisoning scare.

It happened around 2 p.m. at the building located on Tandal Place in Knightdale near the intersection of Interstate 540 and Business 64.

ABC11 crews learned a generator associated with construction happening near the building was operating near the back door of the hospital. Exhaust smell from the generator caused someone to call the fire department.

First responders arrived and help evacuate the building out of an abundance of caution.

No humans or animals were seriously harmed, but they all could be seen gathering in the parking lot outside the building as first responders worked the scene.
