The Laurel Walmart was evacuated Sunday morning due to high carbon monoxide levels in the building, an Anne Arundel County Fire Department spokesman said.

Fire personnel responded to the store in the 3500 block of Russett Green East at 10:27 a.m. for a medical emergency and found an injured employee, Fire Department Lt. Russ Davies said.

The person, whose identity and condition were unknown, was transported to Laurel Regional Hospital.

While at the store, fire personnel discovered high carbon monoxide levels and decided to evacuate the roughly 250 people in the building.

Carbon monoxide is a colorless, odorless and tasteless gas that is toxic to humans and animals when encountered in high concentrations.

The source of the leak appears to be the store’s heating, ventilation and air conditioning system, Davies said. The building was ventilated until carbon monoxide levels dissipated, and employees were allowed to return at around 12:30 p.m.
