Questions from employers in this region
What is the Florida Drug-Free Workplace Act and does it affect our testing program?
Florida's Drug-Free Workplace Act (§ 440.101–.102 F.S.) allows employers who implement a qualifying drug-free workplace program to receive a workers' compensation insurance premium discount of up to 5%. The program has specific requirements for policy, testing procedures, employee notification, and EAP access. For DOT-regulated employees, federal requirements already exceed most state standards. We coordinate collections that meet both frameworks.
Can you collect at JAXPORT vehicle import terminals without disrupting unload operations?
Yes. We stage collections at terminal gates, drayage driver check-in areas, and designated on-site locations within JAXPORT terminals — minimizing vehicle turn time while meeting FMCSA Part 382 chain-of-custody requirements.
CSX is headquartered in Jacksonville — do you cover HQ staff as well as yard workers?
We collect for any CSX employee category requiring DOT testing — FRA covered-service employees at Bowden Yard and throughout the Jacksonville terminal network. Contact us to discuss your specific covered workforce and collection locations.
