Compliance is mandatory. The logistical nightmare is optional.
We handle onsite fit testing and the compliance work around it for California employers — and for larger, multi-site clients nationwide. Scheduling, medical clearances, records, and follow-through are managed end to end, so your managers don't have to moonlight as respirator administrators.
The most expensive part of a fit test isn't the test. It's the commute.
Most companies calculate the cost of a fit test by looking at the clinic's invoice. They entirely forget to account for the hour of driving, the hour in the waiting room, and the resulting plunge in productivity.
At Onsite Fit Testing, we’ve designed a done-for-you solution to systematically eliminate this administrative tax. We handle onsite fit testing for California employers, with nationwide support for larger, multi-site programs. We do the scheduling. We come to you. We handle the paperwork. You simply stay compliant.
- Zero travel time for your workforce
- An end to the administrative headache
- Online medical evaluations, available 24/7
- Digital records and automated expiration alerts
