For safety-sensitive CDL drivers, pipeline workers, railroad crews, defense contractors, and aviation employees who cannot leave a shift for a clinic visit, mobile collection keeps operations staffed while meeting federal custody requirements.

Questions from employers in this region

Publix runs one of Florida's largest private CDL fleets from Lakeland — how do you manage their scale?

We coordinate large-volume on-site random and pre-employment collections at Publix's Lakeland distribution campus, managing scheduling to minimize disruption to delivery dispatch windows. Contact us to discuss your fleet size and testing frequency.

Mosaic's ammonia terminals have strict hazmat protocols — can you collect at those facilities?

We coordinate with your Mosaic EH&S team at Bartow and Mulberry facilities to arrange collector access under site-specific hazmat and safety protocols. All PHMSA Part 199 chain-of-custody requirements are met for ammonia and pipeline-covered workers.

The I-4 corridor has a dense concentration of fulfillment centers. Do you serve multiple warehouses in one day?

Yes. We coordinate multi-stop testing days along the I-4 Lakeland/Plant City corridor — visiting multiple fulfillment center and distribution employer locations in a single day to maximize efficiency for employers with multiple sites.

OnSite Employer Testing is headquartered in Illinois and coordinates mobile and on-site employer testing across selected regions and employer locations—including through partner collectors when your program, timing, and geography allow.
