What OHS does
OHS Health & Safety Services, Inc. (legal entity OHS Inc.) is a family-owned California corporation headquartered in Costa Mesa, Orange County, that operates as a Third Party Administrator (TPA) for workplace safety and drug testing compliance. Founded in January 1991 as one of the original 50 industry innovators in the field, the company delivers a unified service portfolio including onsite and nationwide employee drug testing (pre-employment, random, reasonable suspicion, post-accident, return-to-duty, follow-up), the proprietary WorkFit System℠ post-offer physical evaluation, OSHA Respirator Medical Evaluations, DOT Collector and Supervisor Training, background checks, and written drug testing policy development. Customers include DOT-regulated employers (trucking, public transportation, safety-sensitive industries) and non-DOT general employers across all 50 U.S. states, with operations also extending into Canada.
The company's technology stack combines mobile field operations with online self-service portals. Drug Test Technicians deliver onsite specimen collection at client job sites for groups of 10 to 1,010 employees, supported by CLIA-certified laboratory partnerships for confirmatory analysis and chain-of-custody management. The proprietary WorkFit System℠, developed by an occupational medicine expert based on 300,000+ physical examinations, evaluates candidates against 70+ physical checkpoints and delivers same-day Pass, Accommodate, or Fail determinations within 1-4 hours at a flat $39 per evaluation. The OSHA Respirator Exam is delivered through a digital questionnaire platform reviewed by Board-Certified Occupational Medicine Physicians, producing results in 1-2 business hours. Online training portals at respiratorcertification.com serve individual and SMB buyers for Respirator Exam, Collector Training, Supervisor Training, Employee Training, and Random Selection management.
OHS generates revenue through unit-priced transaction fees ($39 flat rates on WorkFit physicals and OSHA respirator exams), subscription or recurring fees for compliance program administration, and professional services fees for training, certification, and policy drafting. The company reaches customers primarily through direct sales outreach, phone-based consultation, website inquiries, and long-cycle client referrals — managing enterprise TPA programs with up to 224 locations across 26 states while maintaining a long tail of SMB accounts, including its first customer from 1991 still active. Distribution is hybrid: mobile field teams for enterprise onsite events, online portals for self-serve SMB/individual certification, and clinic-network referrals for traditional specimen collection. Customer logos span environmental services, commercial real estate, telecommunications infrastructure, oil and gas exploration, manufacturing, security, trucking, agriculture, and ice manufacturing.
