Verified Across
Every Major Network

Active, audited membership in all seven major contractor qualification platforms used by U.S. industrial operators. Most independent mobile testing providers face a 60–90 day prequalification process at every new facility. Apex is already in.

ISNetworld

The Industry Standard

The largest contractor management platform globally — required by Shell, ExxonMobil, Chevron, Dow, BASF, LyondellBasell, and 700+ operators worldwide. Our current, audited ISN profile with live insurance certificates is the single most powerful door-opener at any Gulf Coast petrochemical facility.

DISA Global Solutions

Drug & Safety Consortium

DISA manages drug testing consortiums and contractor badging for hundreds of Gulf Coast industrial operators. Apex is DISA-certified through the Fastest Labs parent relationship — seamless drug testing, random pool management, and occupational health integration for any DISA-registered client.

Avetta

Supply Chain Risk Management

Avetta serves 500+ enterprise clients across energy, construction, and manufacturing. Verified membership gives Apex immediate access to a massive operator network — competing mobile providers without Avetta face weeks of approval paperwork for every new client.

Veriforce

Pipeline & Energy Sector

The dominant platform in midstream and downstream pipeline, LNG, and natural gas operations — a segment with heavy OSHA medical surveillance requirements and virtually no mobile clinical competitors. Veriforce membership opens the entire Gulf Coast pipeline corridor to Apex.

PEC SafeLand USA

Construction & Contractor Access

SafeLand is the pre-access standard for thousands of Gulf Coast construction and turnaround contractor workers. Our physical, audiometric, fit test, X-ray, and drug test packages align directly to SafeLand badging requirements — making Apex the natural partner for any contractor operating at PEC-managed facilities.

Browz & ComplyWorks

Manufacturing & Cross-Border

Browz (via Avetta) serves U.S. manufacturing and utilities. ComplyWorks maintains prequalification standing for Canadian energy operators and U.S. cross-border contracts — expanding Apex's addressable market well beyond the Gulf Coast.

The Competitive Moat — No Other Mobile Provider Has This

Independent mobile testing operators cannot access most Gulf Coast industrial facilities without a 60–90 day contractor prequalification process for every new client. Apex Onsite's active, current membership across all seven major networks means one phone call, one approved purchase order, and a unit on your site — often within 48 hours.

Mobile Clinic Platforms

The Apex
Mobile Units

Four deployment platforms covering every situation — from large refinery surveillance events and remote MSHA mine sites to a client's existing conference room. Every platform carries digital X-ray, audiometric testing, spirometry, PortaCount fit testing, and full drug collection capability.

Modular building contracts: Minimum 90-day placement. Recommended for 6-month to 2-year programs. Apex handles permitting, crane placement, utility connection coordination, inspection scheduling, and full clinical staff deployment. The client provides a level pad and utility hookup point — Apex does everything else.

What This Is

Apex deploys a fully-equipped, staffed clinical operation inside a room or suite designated by the client inside their existing building — a conference room, training room, break room, or unused office space. No trailer. No modular structure. No construction. Apex brings everything: equipment, supplies, staff, signage, privacy partitions, and portable X-ray.

How it works: Client identifies available space (400 sq ft minimum) and provides a facility contact. Apex handles scheduling, employee notifications, equipment load-in, full clinical operation, results documentation, and teardown — the room is returned to its original state within 60 minutes of the last patient.

Target Markets

Who We Serve

Employers with OSHA-mandated medical surveillance obligations, safety-sensitive workforces, and employee counts that make clinic-based testing impractical. Every segment below carries a legal obligation — not a preference — for the services Apex delivers.

Petrochemical & Refinery

Refineries, chemical plants, and LNG terminals with 500–5,000+ contractor populations. OSHA lead, asbestos, benzene, and hearing programs are mandatory. Gate access, DISA badging, and ISNetworld/Avetta qualification make onsite testing the only practical solution.

EHS ManagerAnnual + TriggerISNetworld

Pipeline & Midstream

Veriforce-managed pipeline operators with heavy OSHA medical surveillance requirements and virtually no mobile clinical competitors. PFT, audiometric testing, X-ray, and fit testing for crews working throughout the Gulf Coast pipeline corridor.

HSE ManagerVeriforceAnnual Mandate

Construction & Industrial

GCs and subcontractors under DISA, ISN, PEC SafeLand, and Avetta programs. Rotating jobsite locations make fixed clinic testing impossible. Apex dispatches to the active site — pre-access badges, annual audiograms, and silica PFT for entire crews in a single day.

Safety ManagerPEC SafeLandPre-Access

Manufacturing & Warehousing

Noise-exposed workers in production environments require annual audiograms. Forklift operators require vision screening. X-ray programs for any asbestos or chemical exposure. Facilities with 50–500+ employees achieve 100% participation rates when Apex comes to them.

HR DirectorAnnual SurveillanceHigh Volume

Transportation & Fleet

DOT physicals required every 1–2 years for all CDL drivers under 49 CFR 391.41. Companies with 25+ drivers lose full route days scheduling clinic visits. Apex brings the FMCSA Medical Examiner to your terminal — physical, audiogram, and drug screen completed before the first truck rolls.

Safety DirectorDOT PhysicalBiennial

Healthcare & First Responders

Hospitals, EMS agencies, and fire departments require annual N95/SCBA fit testing, TB testing, hearing screens, and wellness exams. High headcount, strict compliance, and union agreements create large, predictable annual contracts.

CNO / Safety OfficerAnnual Fit TestContract

Mining & Extraction

MSHA mandates Coal Workers' Health Surveillance including periodic chest X-rays and PFT. Remote mine sites are completely underserved by fixed clinics. Apex's semi-trailer with onboard X-ray and ILO B-reader capability is purpose-built for these deployments.

Mine Safety OfficerMSHAILO B-Reader

Staffing & Workforce Agencies

Industrial staffing firms placing workers in OSHA-covered environments need fast pre-placement physicals, drug screens, audiograms, and fit tests. Apex integrates with LabbOne for tracking — giving staffing agencies a compliance edge over every competitor.
