A fit test taken on Tuesday should not come back after the turnaround starts on Friday. On Site Medical & Safety runs the exams, testing, and surveillance that decide who is cleared to work across Houston, Texas. DOT physicals, drug and alcohol testing, audiograms, respirator fit testing, spirometry, and return-to-work determinations, all under physician oversight and all on one record.
Occupational medicine gets treated as a checkbox until an OSHA 1910.134 fit test record goes missing or a hearing-loss claim arrives with no baseline audiogram to compare against. On Site runs these as a governed program. Physician oversight on the determinations, one record set behind them, and results that arrive before the crew is already on shift.
Commercial driver examinations performed by certified medical examiners on the FMCSA National Registry, with the determination made and the certificate issued the same visit. The driver leaves with the paperwork in hand.
DOT and non-DOT collections run to 49 CFR Part 40 procedure, with Medical Review Officer interpretation standing between a lab result and an employment decision.
Baseline and annual audiograms under OSHA 1910.95, with serial comparison that makes a standard threshold shift visible while it is still preventable, and defensible if a claim arrives.
The 1910.134 medical evaluation and the qualitative or quantitative fit test, run together so a worker is cleared and fitted in one pass.
Pulmonary function testing for workers in silica, asbestos, benzene, and respirator-required roles, tracked over time so the trend shows up while it still matters.
Physician-supported determinations on whether an injured or recovering worker can safely return, with restrictions written clearly enough that a supervisor can actually apply them.
OEUK / OGUK offshore fitness examinations and remote-deployment screening for Houston operators sending crew to assets where a medical problem becomes a helicopter.
Enrollment, completion, expiry, and exception reporting across every surveillance program you run. The view that turns compliance from an annual scramble into a monthly number.
Employers around the metro rarely lose money on the cost of a physical. They lose it on the four days a fit worker spends waiting on paperwork, the contractor crew that shows up to a Baytown or Deer Park gate without current clearances, and the turnaround that starts short-handed because sixty people needed fit tests and the clinic could take twelve a day.
On Site is built to run occupational medicine at industrial tempo. We bring testing to the site when volume justifies it, keep every determination under real physician review, and hold every audiogram, fit test, and surveillance record in one place, so the baseline you need to compare against in three years is actually retrievable. Since 1998 we have done this for operations where being one cleared worker short stops the job.
Learn more about usRespirator medical evaluations and fit testing fall under OSHA 29 CFR 1910.134. Occupational noise exposure and audiometric testing fall under 1910.95, which requires a baseline audiogram and annual comparison. DOT examinations follow 49 CFR 391.41 and must be performed by a certified medical examiner on the FMCSA National Registry. Drug and alcohol testing follows 49 CFR Part 40, including MRO review. Hazardous-waste and emergency-response medical surveillance falls under 1910.120. On Site runs all of them against the same record set.
The value of an occupational medicine program is not the exam. It is knowing, on any given morning, which workers are cleared, which expire this month, and which never completed the surveillance they were enrolled in. HealthLink holds that answer, and it stays yours when you change clinics.
Mobile occupational medicine means sixty fit tests before lunch in a plant parking lot. The pace runs closer to a production line than a clinic. We're hiring clinicians, examiners, and technicians across the metro who can hold clinical standards steady while the volume moves. If that sounds like your kind of work, talk to us.
Send us how many workers need clearing, which exams and testing they need, and when the job starts. We'll come back with a schedule, whether it runs onsite or at a facility, and what the physician review and record retention look like behind it. For plant-side coverage across the metro see our Houston refinery and petrochemical medical services, or our broader Houston programs.
