Safety

Safety awareness is a vital aspect of our work. Since our incorporation in 2007, STS has maintained an exceptional safety record due to our everyday respect for dynamic field environments and our ongoing training, including adherence to ISNet safety, Union Pacific E-Rail, and OSHA’s Hazardous Waste Operations and Emergency Response (HAZWOPER) standards.

In addition to maintaining an exceptional safety record, STS has earned a reputation for extending the same level of care to its business practices. Being respectful of client schedules and budgets, viewing each situation as unique, and working collaboratively with clients often enables STS to suggest novel, yet practical solutions. That responsive, innovative approach helps clients address challenges effectively, while meeting their schedules and controlling, or even reducing, costs.
