Compliance Services Tailored for Your Industry
We've designed these specialized services to address the unique compliance challenges faced by Manufacturing & Industrial businesses. Each service is backed by expert support and proven results.
The Diversified Compliance Platform
Everything we do runs on technology we built — one platform bringing testing results, consortium rosters, driver files, Clearinghouse status, and lab and MRO integrations into a single real-time compliance view. You see where every driver and requirement stands, without chasing paper.
Fit-for-Duty & Return-to-Work Evaluations
Objective fit-for-duty and return-to-work evaluations for current employees — a functional work-readiness assessment by licensed physical therapy professionals, matched to the job's real demands. Used after injury or leave, a safety concern, or a workplace incident to decide who can safely return.
Pre-Employment Drug Testing
A driver can't perform safety-sensitive functions until you have a verified negative pre-employment drug test (49 CFR 382.301). Test at our clinics, on-site with our mobile collectors across Nebraska and Kansas, or at a partner site nationwide. MRO-verified. $75 clinic / $95 mobile.
Audiometric Testing & Hearing Conservation
OSHA 1910.95 hearing testing for noise-exposed workforces — baseline and annual audiograms with standard-threshold-shift tracking. Test individuals at our Lincoln clinic, or bring our growing on-site mobile service to your factory floor for whole-crew baseline and annual screening.
Post-Accident Testing
When an accident happens, the clock starts: DOT requires alcohol testing within 8 hours and drug testing within 32 (49 CFR 382.303). Our 24/7 dispatch and our own collectors across Nebraska and Kansas get a driver tested — and every attempt documented — so you meet the window and stay defensible.
Vision Screening (Snellen & Color Vision)
Fast, low-cost vision screening — Snellen visual acuity and Ishihara color vision — most often built into a custom pre-employment or occupational-health package alongside functional, drug, and hearing testing. Also a quick pre-check that a driver meets the DOT 20/40 standard.
Reasonable Suspicion Testing
When a trained supervisor observes signs of drug or alcohol use, the test must happen fast. Our collectors dispatch same-day, on-site across Nebraska and Kansas, 24/7 — determination and collection documented to keep it defensible. Supervisors need DOT training first; we offer that too.
Post-Offer Back & Musculoskeletal Screening
Post-offer back and musculoskeletal screening for material-handling roles — a job-matched functional assessment by licensed physical therapy professionals that confirms a new hire can handle the lifting and documents a musculoskeletal baseline to defend against future injury claims.
Return-to-Duty & Follow-Up Testing
After a drug or alcohol violation, a driver can't return to safety-sensitive duty until they pass a directly observed return-to-duty test — then complete a SAP-prescribed follow-up plan of unannounced, observed tests (at least 6 in the first year). We run every test and keep the plan on track.
Post-Offer Physical & Functional Screening
Post-offer functional and physical-ability screening built around each job's real demands — lift, carry, push/pull, range of motion — administered by licensed physical therapy professionals and optionally paired with a pre-employment drug screen. Match the right hire to the work before day one.
24/7 Emergency Response & DER Support
Small fleets can't keep a 24/7 compliance desk — but a post-accident at 2 a.m. or a positive result on a Friday can't wait. We're your around-the-clock backup: emergency collector dispatch, plus expert DER guidance on removals, post-accident calls, and reasonable-suspicion procedures.
Supervisor Reasonable Suspicion Training
DOT requires every supervisor of CDL drivers to complete at least two hours of reasonable-suspicion training — 60 minutes on drug use and 60 on alcohol misuse (49 CFR 382.603). Ours is led by instructors with law-enforcement backgrounds, delivered online or in-person, for one supervisor or a team.
Medical Review Officer (MRO) Review
Every non-negative drug result must be verified by a qualified Medical Review Officer before it's reported, so a valid prescription never becomes a false positive. Our DOT-qualified MRO network reviews every result — built into our testing, or standalone for specimens you collect.
DER Training & Certification
Your Designated Employer Representative (DER) is the person who receives test results and pulls a driver from duty — and getting those calls right matters. Our DER training walks your DER through their DOT responsibilities: handling results, removals, return-to-duty, and Clearinghouse actions.
Mobile Drug & Alcohol Collection
Our own certified collectors across Nebraska and Kansas bring drug and alcohol testing to your terminal, job site, or accident scene — instead of pulling drivers off the road. Random, pre-employment, post-accident, reasonable-suspicion, and return-to-duty tests, collected on-site. $95 per test.
Compliance Consultation
Have a DOT or FMCSA question that doesn't fit a standard service — an audit notice, a new-authority setup, a corrective action plan, or a regulation call you can't afford to get wrong? We consult on any DOT and FMCSA compliance matter by the hour, from the team that runs carrier programs every day.
Breath Alcohol Testing
DOT evidential breath alcohol testing by certified Breath Alcohol Technicians — for random, post-accident, reasonable-suspicion, return-to-duty, and follow-up needs. Collected on-site by our mobile team across Nebraska and Kansas or at any clinic, on DOT-approved devices. $55 per test.
SAP Coordination
When a driver violates DOT drug or alcohol rules, they can't return to duty without completing the Substance Abuse Professional (SAP) process. Our qualified SAP on staff handles it end to end — the evaluation, the recommended education or treatment, the return-to-duty test, and the follow-up plan.
Non-DOT / Employer Drug & Alcohol Testing
Not every employer is DOT-regulated — but you still need a drug and alcohol program that's consistent and defensible. We build and administer non-DOT testing on your terms: pre-employment, random, post-accident, and reasonable-suspicion, with instant or lab panels, on-site or in-clinic.
Respirator Fit Testing & Medical Evaluations
OSHA respirator fit testing and provider-reviewed medical evaluations for N95 and half-mask respirators, with optional pulmonary function testing. Use DSC for the fit testing, the evaluation, or the complete program — on-site, in-clinic, or at a coordinated event.

We offer a comprehensive suite of DOT compliance services beyond these industry-specific solutions. Explore our full catalog or speak with a specialist.
Manufacturers carry a heavy occupational-health load — respirator programs, hearing conservation, functional screening, and drug and alcohol testing across shifts and job classes. Diversified handles all of it, so your safety and HR teams don't have to stitch together three vendors.
We bring OSHA-required testing to your floor: qualitative respirator fit testing (29 CFR 1910.134), audiometric testing for your hearing conservation program (29 CFR 1910.95), vision screening, and post-offer physical and musculoskeletal screening matched to the physical demands of the job. For drug and alcohol testing we run both non-DOT employer programs and full DOT programs for any regulated drivers, with 24/7 collection for post-accident and reasonable-suspicion events.
Our mobile collectors come to your plant across Nebraska and Kansas, with national coverage through our lab-partner network for multi-site manufacturers. Every result is documented and tracked, so annual fit-test and audiogram due dates never slip.
Unique compliance challenges in Manufacturing & Industrial.
Every industry faces distinct compliance hurdles. Here is what we help you overcome.
A Stack of OSHA Programs to Run
Respirator fit testing, hearing conservation, and functional screening each carry their own schedule and documentation — and keeping all of them current across shifts is a real administrative load.
High-Volume Hiring and Turnover
Every new hire needs a post-offer physical and pre-employment test before they touch equipment, and hiring surges can’t wait days for appointments.
After-Hours Incidents on the Floor
A post-accident or reasonable-suspicion event on a night shift has to be tested within tight windows and with clean chain of custody — not whenever a clinic opens.
