The haze was determined to be caused by a leak of Freon, a chemical used refrigeration and air conditioning. Inhaling the chemical can cause respiratory issues and can lead to more serious medical problems if it is inhaled in a high concentration.

The leak was secured in the store by 1:23 p.m., and a hazardous materials team confirmed that the building was safe once again. The store re-opened around 3 p.m.
