Health and Safety

Journey to ZERO

At Halliburton, Journey to ZERO is our vision to achieve ZERO safety incidents, ZERO environmental incidents, and ZERO non-productive time — every day, on every job.

The guiding principles below support and enable our Journey to ZERO progress. While specific focus areas evolve annually, these principles remain consistent each year:

• Oversight from the Board of Directors' HSE Committee
• Execution and robustness of the Halliburton Management System
• Training and education
• Identification and communication of personal and process safety risks
• Commitment to continuous process improvement
• Verification of our HSE and SQ performance

Throughout 2022, we focused on risk management, refreshed primary scorecard metrics, and continued evolution of our incident investigation program. We also tied in our GHG emissions, waste, and water-reduction efforts that were highlighted in the Environmental section of this report. We completed 100% of our 2022 Journey to ZERO objectives

Risk Management

In 2022, each of the product lines built on our 2021 improvements to the Company's risk-management processes by expanding the content and utilization of the digital risk-assessment platform released in Q4 2021. This was supported by a new Risk Management Planning training module focused on job planning risk assessments. 94% of personnel assigned this module completed it during 2022.

Critical Focus Areas

Over the past 10 years, we have made tremendous progress in reducing total recordable injury rates. We have also made improvements toward reducing significant incidents; however, opportunity still exists to reduce the potential for serious and life-altering events. In 2022, we assessed our primary scorecard metrics and found an opportunity to bring our highest potential personal and process safety incidents to the forefront.

Our Critical Focus Areas (CFA) present the highest potential for process safety risks. CFA incidents have potential to result in catastrophic loss involving groups of people, whole processes, and the communities where we work. We mitigate these risks with our robust processes and systems as defined in our HMS. In addition to highlighting these on the frontpage scorecard in 2022, we updated our CFA supporting documents in HMS and published a new CFA video series. These videos featured product line vice presidents and geography product line leaders reinforcing why CFA awareness is vitally important to their business and methods for preventing potentially devastating impacts. Product line country or area teams utilized these videos to facilitate a series of extended safety conversations about how a given CFA relates to local activities, how the team uses HMS CFA one sheets and critical thinking to recognize and prevent CFA process safety events, and how we prepare for and respond to worst case scenario events to ensure personnel safety. The CFA video series had over 7,000 views in the second half of 2022.

Halliburton Critical Focus Areas:

• Well Barriers: Manage well barriers to prevent uncontained release of formation fluids
• Hydrocarbons to Surface: Control the well to prevent unintended flow to the surface
• Pressure Control: Control pressurized systems at all times
• Well Proximity: Plan and maintain non-intersecting drilling trajectories to avoid a collision
• Radiation and Explosives: Adhere to global and local regulatory safety requirements at all times

Leadership Visits

Our 2022 scorecard assessment also highlighted leadership visits as the primary leading indicator to reinforce desired behaviors and outcomes. As travel reopened in 2022, our leadership teams were able to resume field workshop and customer job site visits. This aligned with the introduction of a leading indicator that measures monthly operational leadership visit execution. Leadership visits are focused on engagement with frontline employees to ensure processes are working as intended and to gather process improvement feedback. Management Process Execution Assurance (MPEA) is a checklist tool that provides leadership with a question set designed to facilitate frontline conversations about the highest risk tasks and processes. In 2022, our product lines and Global HSE/SQ team conducted a systematic review of critical process risks and HSE/SQ program findings and refreshed the MPEA checklist question sets. This resulted in the creation of new product line-specific questions and refreshed critical HSE program questions with simplified terminology designed to foster two-way dialogue. During 2022, we improved by 256% in monthly leadership visits utilizing the updated checklists.

Incident Investigations

Learning from incidents with the potential for serious or life altering results remains a critical part of our Journey to ZERO. In 2022, we expanded our investigation training curricula to differentiate event investigation facilitators, investigation training facilitators, and subject matter experts. Within the investigation training content, we included a new Fair Outcome Model assessment for investigations that identify where our processes were not followed as intended. The Fair Outcome Model assessment allows for better application of our human performance principles when we assess what led to process variation. The assessment takes a holistic view of individual and supervisory behaviors to identify potential underlying conditions or systematic issues. To support this process improvement, and in collaboration with Human Resources, the Company hosted a series of Fair Outcome Model training sessions both globally and in each region. We also established monthly global investigation community calls to further collaboration and sharing of lessons learned across the regions.
