Sending an employee to a clinic costs more than the test: travel time, waiting rooms, a shift with a hole in it, and, for a random program, the scheduling puzzle of getting notified employees to a fixed site immediately. On-site collection removes most of that. The collector arrives at the workplace, the selected employees are tested during the shift, and the operation keeps moving. This guide lays out where on-site collection makes the most difference and how the logistics run.
The short version
- Shift workforces and multi-site employers see the largest gains
- The same Part 40 chain of custody applies in the field, on the Federal form for DOT tests
- Random selections convert to completed collections faster when the collector comes to the site, which is what the rule's proceed-immediately requirement needs (49 CFR 382.305(l))
- Breath alcohol testing can run on site alongside urine collection, inside the window the rule allows for alcohol tests
