Emergency responders and police will be at the downtown post office as officials conduct a full-scale simulated emergency drill today.
The drill, which is being held from until 6 p.m., includes evacuation and decontamination of employees, customers and visitors; securing the crime scene; and isolating, controlling and tracking contaminated mail.
According to a news release, a biohazard detection system will signal a positive alert for mail with aerosolized Bacillus anthracis, or the bacteria that causes anthrax, at 4 p.m. The detection will signal the start of the exercise.
A perimeter might be set up disrupting traffic on Eighth and Ninth streets.
The exercise is done in conjunction with the North Florida District National Preparedness specialist.
