For Employers

Construction Drug Testing

Construction has some of the highest injury and fatality rates of any industry, and post-injury opioid and fentanyl use is a real risk. A testing program protects your crew, cuts workers’ compensation exposure, and can earn insurance credits.

Why construction tests

Heavy equipment, heights, and power tools make impairment catastrophic. Many states offer workers’ comp premium discounts for a qualified drug-free-workplace program, and post-accident testing is central to liability defense.

The right program for job sites

Run pre-employment on every hire, keep post-accident kits in the trailer, and use a 14-panel so fentanyl is covered.
