Health, Safety & Environment


Safety Vision Statement

U.S. Well Services, LLC (“USWS”) believes that all incidents are preventable and that priority one is having all employees go home healthy every day.

To accomplish this mission, we actively encourage every employee to take personal responsibility for their individual safety as well as the safety of their entire crew. We have also created "10 Pillars of Safety" to help our clients and employees stay safe at all times.

Stop Work Authority (SWA)

SWA is the Company’s commitment to our employees of their right to ask questions if anyone feels that they are in an unsafe situation or being asked to perform an unsafe task. Although SWA may require shutting down the job on occasion, in most cases simply answering a question is enough to resolve the matter. In those cases where a shutdown is necessary, USWS has an established "restart protocol". Senior operations and HSEQ personnel will collaborate to remedy the situation. Once resolved, the matter will be discussed with all affected employees, the unsafe condition will be eliminated, and then work can resume safely.

SWA Commitment

"At US Well Services, one of our core values is that each and every person should go home safe every day. We try to make this happen by simply looking out for each other. A powerful tool to accomplish this is your Stop Work Authority (“SWA”). Simply put, you have the right to ask questions, to point out an unsafe act or condition, or to state that you are not properly trained to perform a task. Your supervisor will then work with you to rectify the situation. You have my personal guarantee that any employee who validly uses SWA will not face discipline of any kind. If any employee feels that they are receiving any negative response because they used SWA, then contact me immediately."

— Richard P. Hoffman, Vice President of HSEQ

HSE-Nexus is the comprehensive safety database developed by U.S. Well Services. This database allows the seamless integration of several different data sets and allows USWS to view the information more holistically, while increasing our capabilities to spot and predict service quality trends. HSE-Nexus truly is where data becomes information.


PSM360® is a program developed by U.S. Well Services that incorporates our lean operations mindset (LEAN360®) with a traditional program of process safety management (PSM). The LEAN360® program focuses on eliminating waste (defects, overproduction, waiting, non-utilized talent, transportation, inventory, motion, and extra processing) with a 6S approach--safety, sort, set in order, shine, standardize, and sustain.

PSM360® is a program whereby safety is embedded into a task or procedure via administrative controls, training, risk hazard analysis, incident investigation, emergency planning, audits, contractor management, and employee involvement.


USWS-U® is the remote training program developed by U.S. Well Services. This remote learning program supports traditional classroom and hands-on training by giving our mobile workforce additional opportunities to complete training electronically through videos and virtual classrooms. The training modules include safety policy refreshers, equipment/task support, and other professional development learning opportunities.
