Dr. Bridgette Gandy, left, and Detrick White, both with Jackson-based Envirohance Consultants, don protective suits and use special equipment to deep clean and sanitize Charleston City Hall Monday morning. White is pictured spraying a sanitizing mist into the air. Hard surfaces were wiped down or cleaned with a handheld ultraviolent light wand. The city government building was closed for more than two hours to allow for the cleaning of all City Hall offices, including the police department and courtroom facilities. Gandy said they were called in strictly as a precautionary measure after a close family member of a City Hall employee was exposed to someone who had tested positive for COVID-19.
