Workplace Drug and Alcohol Testing Services
Why Drug and Alcohol Testing Is Essential for Workplace Safety
We offer drug & alcohol testing services for companies across various industries. Our company utilizes DISA and Team Alert.
Types of Workplace Drug and Alcohol Testing We Offer
Workplace drug and alcohol testing services aren’t one-size-fits-all, and most employers need more than a single test type to stay compliant and protect their crews. Pre-employment drug screening is the most common starting point, run before a new hire ever sets foot on site, and it’s often paired with a random drug testing program that keeps testing unpredictable throughout employment rather than only at hiring. Beyond those two, we support post-incident testing, reasonable suspicion testing, and return-to-duty testing — all delivered through our partnerships with DISA and Team Alert so results are fast and defensible.
For oil & gas clients specifically, oilfield drug testing often carries additional operator-specific requirements on top of standard workplace drug and alcohol testing services, and we build programs that satisfy both layers at once rather than running separate tracks.
Industries We Serve: Construction, Oil & Gas and Industrial
Construction sites are where a strong construction site drug and alcohol policy matters most — high-risk equipment, multiple subcontractors on one site, and frequent operator audits all raise the stakes of an untested workforce. Oilfield drug testing follows a similar logic but often layers in DOT requirements depending on the role, since many oilfield positions involve commercial driving or safety-sensitive equipment. Industrial and manufacturing clients typically land somewhere between the two — fewer DOT-regulated roles, but still enough machinery and injury risk to justify a full random drug testing program rather than pre-employment screening alone.
Whatever the industry, workplace drug and alcohol testing services work best when they’re built into policy from day one rather than added reactively after an incident. A documented construction site drug and alcohol policy also gives supervisors clear, consistent grounds to act on reasonable suspicion instead of navigating it case by case.
DOT vs. Non-DOT Testing: Why the Distinction Matters
Not every workplace drug and alcohol testing services program falls under the same federal rules. DOT-regulated positions — commercial drivers, certain safety-sensitive oilfield roles — are subject to strict federal collection, chain-of-custody, and reporting requirements that don’t apply to non-DOT employees. Getting this distinction wrong is a common compliance gap we see, particularly on sites where DOT and non-DOT workers overlap day to day. We help clients map out which roles require DOT testing protocols and which fall under a standard random drug testing program, so the right rules apply to the right employees from the start.
Building a Construction Site Drug and Alcohol Policy That Holds Up
A construction site drug and alcohol policy is only as strong as its documentation and consistency. We help clients draft policy language that clearly defines pre-employment drug screening requirements, random drug testing program frequency, and post-incident procedures, then make sure supervisors are trained to apply it the same way every time. That consistency is what protects employers if a testing decision is ever challenged.
Why Partner With EHSS® for Workplace Drug and Alcohol Testing
Our workplace drug and alcohol testing services run through DISA and Team Alert, giving clients fast turnaround and a defensible chain of custody without managing lab relationships directly. Combined with our broader safety consulting work — audits, policy writing, and accident investigation — testing becomes one piece of a program we already understand end to end, rather than a standalone vendor relationship. Reach out and we’ll help determine the right mix of pre-employment drug screening, random testing, and oilfield-specific requirements for your operation.

What is workplace drug and alcohol testing?
Workplace drug and alcohol testing services are programs employers use to screen employees for substance use, typically at hiring, on a random schedule, after an incident, or when there’s reasonable suspicion. The goal is reducing impairment-related incidents on job sites where equipment and working conditions carry real safety risk. Programs are usually built around a documented policy so testing decisions are consistent and defensible.
Is drug testing required in the construction industry?
There’s no single federal law requiring drug testing across all construction work, but many general contractors, operators, and insurers require it as a condition of working on their sites — and DOT rules mandate testing for certain safety-sensitive positions regardless of general industry requirements. In practice, most construction companies end up needing some form of testing program to stay eligible for the jobs they want. A clear construction site drug and alcohol policy makes it easier to meet whichever set of requirements applies.
What's the difference between DOT and non-DOT testing?
DOT testing follows strict federal collection, chain-of-custody, and reporting rules and applies to specific safety-sensitive roles, including many commercial driving and certain oilfield positions. Non-DOT testing follows employer policy rather than federal mandate, giving companies more flexibility in how they structure a random drug testing program. Getting the two mixed up — applying non-DOT procedures to a DOT-covered role, for example — is one of the most common compliance mistakes we see.
How does a random drug testing program work?
A random drug testing program selects employees for testing on an unpredictable schedule throughout the year, rather than only at hiring, using a computer-based selection process to keep it defensibly random. This is what actually deters ongoing use, since employees can’t anticipate or plan around a testing date. We help clients set selection rates and procedures that meet DOT requirements where applicable and stand up to scrutiny otherwise.
What types of workplace drug and alcohol testing services are available?
Beyond pre-employment drug screening, most programs include random testing, post-incident testing, reasonable suspicion testing, and return-to-duty testing after a policy violation. Oilfield drug testing and other DOT-regulated positions typically layer additional federal requirements on top of these standard test types. We build programs through DISA and Team Alert that cover whichever combination your operation needs.
How does onsite testing help employers?
Onsite testing keeps employees on or near the job site instead of losing hours traveling to an outside collection facility, which matters most for random and post-incident testing where speed affects chain-of-custody integrity. It also makes reasonable suspicion testing more practical, since supervisors can act immediately rather than scheduling an appointment. For employers managing a construction site drug and alcohol policy across multiple locations, onsite testing keeps the process consistent site to site.
