Employee Drug Testing

Drug Testing- All Cities, All 50 States

Employee drug testing has been our core business at OHS Inc. since 1991. Our workplace drug testing clients include companies with 2-3 employees to more than 30,000. Today, we proudly still serve our very first 1991 client!

Workers' Compensation

Reducing Workers' Comp Claims

Our proprietary pre-placement physical evaluation determines whether your job candidates are physically fit to do the job SAFELY- without injury. Our strategy will dramatically reduce the frequency of your Workers' Comp claims!

DOT Supervisor Training

Reasonable Suspicion Training

Our Supervisor Training is fully DOT-compliant. This two hours of "reasonable suspicion" training is a federal requirement for supervisors of DOT-regulated personnel. OHS Inc. strongly recommends it for all supervisors!

OSHA Respirator Exams

OSHA-Compliant Exam & Certification

Federal OSHA standard 1910.134 requires a medical survey be completed by all employees that use a respirator. Take our OSHA-compliant exam in English or Spanish, online or use our 800# IVR phone program, anytime 24/7!

OHS Inc. and Local Youths at Risk

OHS Inc. cares about our community, and keeping local families drug-free. So, we help families where it counts the most!

OHS Inc. provides random drug testing services at our cost, to any parent who brings their child to our Costa Mesa offices for drug testing. As parents (and grandparents) ourselves, we want the best for our children. We've learned that drug testing children randomly strongly enables them to resist today's tougher-than-ever peer pressure (i.e., "I can't!  My parents drug test me!"). Random drug testing helps protect them from losing focus in school, and helps keep them on a drug-free, brain-healthy path to responsible adulthood.
