Police union leader: 911 dispatchers may be exposed to asbestos The leader of Palm Beach County’s police union is calling for nearly 100 dispatchers and radio operators to be moved from the sheriff’s office headquarters undergoing renovation work on Gun Club Road, saying the workers have been “forced to endure” potential exposure to hazardous materials like asbestos. The “first responders of the first responders” have been working out of the sheriff’s office headquarters while it undergoes a $42 million renovation, most of which is paid for with sales tax dollars. The headquarters houses the central location for the county’s 911 communications.
