Safe Operations Through Discipline, Accountability, and Continuous Improvement
DHI is committed to providing a safe, responsible, and efficient work environment for our employees, customers, contractors, and the communities in which we operate. Through training, operational discipline, compliance, engineering oversight, and continuous improvement, we strive to conduct all operations with integrity and professionalism.
At DHI, safety and operations are not viewed as separate functions. Safe operations are operations performed correctly, deliberately, and with proper planning, equipment, communication, and risk management. We believe operational excellence and safety performance are inseparable.
Our objective is not only regulatory compliance, but the development of a long-term operational culture focused on incident prevention, environmental responsibility, accountability, and continuous learning.
Minimizing Environmental Impact
DHI is committed to minimizing environmental impact across all areas of operation. We continuously evaluate our activities, equipment, procedures, and work practices to identify environmental risks and opportunities for improvement.
Our operations are designed and managed with consideration for spill prevention, fluid containment, waste handling, water management, emissions reduction where practical, and responsible resource utilization. Environmental protection is incorporated into planning, mobilization, operation, maintenance, and demobilization activities.
DHI works diligently to remain current with applicable state, federal, and customer environmental requirements and seeks to operate in a manner that reflects responsible environmental stewardship.
Through training, procedures, operational controls, and field supervision, employees are educated on safe environmental work practices and expected to immediately report environmental concerns, near misses, spills, releases, or unsafe conditions.
Our long-term objective is to achieve operational performance that protects both people and the environment while supporting sustainable and responsible industrial activity.
Employee Accountability and Operational Responsibility
DHI employees are the foundation of the company’s Health, Safety, and Environmental program. Every employee, supervisor, and manager shares responsibility for maintaining a safe and professional work environment.
Safety is a condition of employment at DHI. All employees are required to comply with company policies, procedures, operational standards, customer requirements, and training expectations. Employees are expected to actively participate in safety meetings, hazard reviews, training programs, job safety analysis processes, and risk management activities.
Each employee has both the authority and the obligation to immediately report unsafe acts, unsafe conditions, environmental concerns, process upsets, equipment deficiencies, or any operation that presents an immediate threat to personnel, equipment, the environment, or the public.
All DHI employees maintain Stop Work Authority regardless of operational impact, cost, schedule pressure, or customer demands. No task, operation, or objective takes priority over the prevention of serious injury, environmental harm, or uncontrolled operational risk.
Managers and supervisors are expected to lead by example and are held accountable for the safety performance, operational discipline, training, and preparedness of the personnel they oversee. Incidents, near misses, equipment failures, environmental events, and operational deviations are reviewed to identify root causes and implement corrective actions designed to prevent recurrence.
Engineered Safety and Process Risk Management
DHI recognizes that many field operations involve significant mechanical, hydraulic, chemical, electrical, and process-related hazards. For this reason, safety at DHI extends beyond basic compliance and includes engineered operational controls, planning systems, and process risk management practices.
Operational planning may include:
Process Hazard Analysis (PHA)
Job Safety Analysis (JSA)
Management of Change (MOC)
Pre-Startup Safety Reviews (PSSR)
Hydraulic modeling and flow analysis
Equipment readiness verification
Field communication planning
Emergency response preparation
Operational monitoring and escalation procedures
DHI believes risks should be identified and controlled during the planning stage whenever possible rather than relying solely on reaction during operations.
Where appropriate, DHI utilizes operational monitoring systems, instrumentation, SCADA integration, alarms, pressure monitoring, flow monitoring, and engineered safeguards to improve operational visibility and reduce risk exposure.
Dedicated to a Substance-Free Workplace
DHI is committed to maintaining a drug- and alcohol-free workplace. Employees are required to report to work fit for duty and capable of safely performing their responsibilities.
The use, possession, distribution, or impairment from illicit drugs, controlled substances, alcohol misuse, or any substance that compromises safety or operational judgment is strictly prohibited.
Employees are expected to comply with all company drug and alcohol policies, including applicable testing requirements, fitness-for-duty expectations, and customer-specific requirements. These policies are administered in accordance with applicable laws and regulations.
Safety as a Culture
DHI’s safety management system is designed to evolve continuously as operational experience, technology, regulations, and industry best practices advance.
Safety awareness, hazard recognition, operational discipline, and risk evaluation are expected to become part of everyday decision-making across all levels of the organization. DHI utilizes behavior-based observation systems, field audits, operational reviews, training programs, and lessons learned to strengthen company-wide awareness of operational risk.
Risk analysis and job safety evaluation are integrated into operational planning processes to ensure work is properly assessed before execution. DHI strives to ensure employees have the proper equipment, procedures, communication, supervision, and training necessary to perform work safely and effectively.
No employee should ever be placed in a situation where they are uncertain about the work being performed, the hazards involved, or the proper response to changing conditions.
The success of the DHI Health, Safety, Environmental, and Governance program depends on the full participation, accountability, and support of every employee across the organization.
Our commitment is continuous improvement, responsible operations, and the pursuit of zero incidents across all DHI locations and operations.
