Mobile occupational health services bring board-certified clinical support to your job site
For construction contractors, industrial employers, and project-based operations across Texas, getting workers to a clinic is not always practical – and sometimes it is not even legal. When post-accident DOT testing has a two-hour window, when 120 workers need to be screened before a project mobilizes, or when OSHA requires respirator fit testing before your crew enters a confined space, a fixed clinic 40 miles away is not a solution.
Occucare International deploys mobile occupational health units directly to your worksite, staging area, or remote project location. Drug testing, pre-employment physicals, OSHA surveillance exams, and mobile clinic response – everything your safety program requires, without pulling a single worker off the job.
What Occucare's Mobile Medical Units Do for Employers
Our mobile units are not a convenience service. They are a compliance and cost-control tool. Every deployment is supervised by our occupational medicine team and integrated with our injury management and medical direction programs – so the care your workers receive in the field is connected to a clinical oversight model, not an isolated appointment.
DOT and non-DOT drug and alcohol testing
 Certified chain-of-custody collections conducted by trained technicians with MRO review. Post-accident, random, pre-employment, reasonable suspicion, and return-to-duty testing – conducted at your site within the regulatory window.
Pre-employment and pre-placement physicals.
Employer-directed medical screenings conducted onsite before workers are cleared for duty. Includes occupational history review, physical examination, and task-specific assessments.
OSHA medical surveillance and compliance testing
 Respirator fit testing (OSHA 1910.134), pulmonary function tests (PFT/spirometry), audiometric testing, and baseline medical surveillance required under OSHA substance-specific standards. Brought directly to your facility or project site.
Mobile clinic response
Acute injury triage, wound care, and first-response occupational injury evaluation conducted onsite to reduce unnecessary ER referrals and protect your experience modification rate (EMR).
Built for Construction, Industrial, and Project-Based Employers
Mobile occupational health services are designed for employers where fixed-clinic access is a barrier to compliance and workforce productivity. If your operation matches any of these scenarios, mobile deployment is built for you:
- General contractors running large or remote construction projects where transporting workers to a clinic creates scheduling delays and project risk.
- Industrial employers with seasonal or project-driven high-volume hiring who need to screen large crews in a short mobilization window.
- Oil and gas operators at upstream, midstream, or remote field locations where the nearest clinic is hours away and OSHA or DOT compliance cannot wait.
- Employers with DOT-regulated drivers or equipment operators who need certified post-accident or random testing completed at the worksite to preserve chain of custody.
- Any employer with OSHA-mandated medical surveillance requirements who needs fit testing, PFTs, or baseline exams completed before work begins – not weeks later.
Mobile Medical Units - What We Deploy
Our mobile platform covers three specialized deployment types. Each can be requested independently or combined in a single worksite visit.
Acute injury triage, wound care, and first-response occupational health delivered at your project site. Reduces ER referrals and protects your EMR.
DOT and non-DOT certified testing at your worksite. Post-accident, random, pre-employment, and return-to-duty – with full chain-of-custody and MRO review.
Respirator fit testing, PFT/spirometry, audiometric exams, and pre-placement screening. OSHA compliance delivered to your staging area.
How We Deploy to Your Site - Three Steps
Pre-employment medical screening sits at the intersection of four separate regulatory frameworks, each governing a different aspect of the clearance decision and the documentation that supports it. Compliance is not optional, and the standards do not align cleanly – the employer is responsible for meeting all four simultaneously.
Step 1
Request deployment and confirm services needed
Tell us your location, the services required, the number of workers, and your timeline. We confirm availability and the specific unit configuration needed.
Step 2
We schedule and dispatch the unit to your worksite
Our team coordinates logistics, credentialing, and equipment. For DOT testing, we confirm chain-of-custody protocols in advance. For OSHA compliance exams, we review the specific standard requirements before arrival.
Step 3
Testing conducted onsite, results delivered to your safety team
Results, documentation, and medical clearances are delivered directly to your safety director or HR manager. For DOT results, MRO review is completed before reporting. All records are maintained in compliance with applicable regulatory requirements.
Why Houston Employers Choose Occucare for Mobile Medical Services
Most mobile testing vendors are just collection sites on wheels. Occucare’s mobile program is different because it is integrated into a full occupational health model supervised by board-certified occupational medicine physicians.
Physician oversight on every program
Our occupational medicine physicians review protocols, supervise clinical staff, and maintain medical director oversight of all testing programs. Not a standalone vendor – a clinical program.
True chain-of-custody drug testing
Every DOT and non-DOT drug screen is conducted under a documented chain-of-custody protocol with MRO review before results are reported. Your program is legally defensible.
OSHA and DOT compliant across all testing types
Our testing protocols are built to 49 CFR Part 40 for DOT and to applicable OSHA substance-specific standards for surveillance exams. We know what a compliance violation looks like – and we prevent them.
Integrated with case management and medical direction
When a mobile clinic response identifies an injury, that case enters our active case management system immediately. Nothing falls through the cracks between the job site and the clinic.
Not a regional vendor - a Texas-wide deployment model
We serve the Houston metro area and deploy to project sites across Texas. Remote oil and gas locations, pipeline corridors, and large construction projects outside the city are all reachable.
Frequently Asked Questions About Mobile Occupational Health Services
Mobile units can conduct DOT and non-DOT drug and alcohol testing (urine, breath alcohol), pre-employment and pre-placement physicals, respirator fit testing under OSHA 29 CFR 1910.134, pulmonary function tests (spirometry), audiometric exams, and acute injury triage and first-response care. Multiple services can be combined in a single deployment to minimize disruption to your project schedule.
Yes. All DOT drug testing is conducted in accordance with 49 CFR Part 40 requirements, including proper specimen collection procedures, tamper-evident packaging, and MRO (Medical Review Officer) review before results are reported to the employer. Our collectors are certified and trained in DOT collection procedures. Post-accident testing is prioritized for same-day or next-day deployment within the regulatory testing window.
For most services, same-day or next-day deployment is available for Houston-area job sites. Post-accident DOT testing is treated as urgent and expedited accordingly. For large-scale pre-employment screening events, we recommend scheduling 3 to 5 business days in advance to confirm technician availability, equipment configuration, and logistics for your site.
Yes. A single deployment can include drug and alcohol testing, pre-employment physicals, and OSHA compliance exams - processed consecutively so your workers move through a complete screening in one session. Combined deployments are commonly used by general contractors during project mobilization, when an entire incoming crew needs to be cleared before their first day of work.
Yes. Occucare deploys mobile units to project sites across Texas, including remote construction, oil and gas, and pipeline locations. We also support multi-site employers with deployment scheduling across multiple active projects. Contact us with your location and scope and we will confirm coverage and logistics for your specific project.
Several OSHA standards mandate employer-provided medical surveillance that can be conducted via mobile deployment: Respiratory Protection (29 CFR 1910.134) requires medical evaluation before employees wear respirators. The Confined Space Entry standard (29 CFR 1910.146) requires medical clearance for authorized entrants. OSHA hazard-specific standards for silica, asbestos, lead, benzene, and noise require baseline and periodic medical exams. Mobile deployment allows employers to meet these obligations without removing workers from the site for extended periods.
