HSE Management System

“

Our HSEMS systematically identifies, assesses and manages risks to safeguard employees, contractors and the environment. It ensures ongoing risk identification, prioritization and control while promoting continuous improvement in implementing HSE policies, meeting leadership expectations and upholding core values.

The HSE Management System is foundational to the safe, reliable operations of our facilities.”

Rich Harbison Executive Vice President, Refining

The HSEMS comprises four distinct phases with 15 interrelated elements:

PLAN

DO

ASSESS

ADJUST

Identify hazards, risks and regulatory requirements then establish strategic plans and objectives accordingly.

Implement tools for managing identified risks and requirements.

Ensure effective risk management through detailed monitoring and auditing.

Review the HSEMS to identify strengths, gaps and opportunities for improvement.

Review

Policy and Leadership Risk Assessment

Audits

Legal Requirements and Standards of Operation

Properly implementing each element is essential for HSEMS effectiveness.

Each phase builds on the previous one to ensure comprehensive risk management.

1 POLICY AND LEADERSHIP Phillips 66 leaders play a crucial role in implementing and driving HSE policy adherence. They ensure policies are clearly communicated to all stakeholders and promote a dynamic safety culture aimed at preventing incidents. By actively engaging the workforce on HSE issues, leaders foster an environment where safety is prioritized, and employees are empowered to identify and address unsafe practices and conditions.

Stop Work is an obligation of every worker, every job, every day.

2 RISK ASSESSMENT Our risk assessment practices encompass comprehensive hazard identification, risk evaluation and analysis, and risk mitigation strategies. We thoroughly evaluate tasks, projects and products using scalable methods tailored to the severity of the risk.

We update risk assessments using a variety of resources. In addition to regulatory requirements, these may include incident investigations, audits, HSE metrics analyses, and stakeholder feedback.

Phillips 66 uses Process Hazard Analysis (PHA) to systematically analyze the design of each process to look for possible causes of process safety events.

For events with the most severe consequences, we go even further and use Levels of Protection Analysis (LOPA). Safeguards identified in LOPA are called Independent Protection Layers (IPLs).

Safeguards We use the Hierarchy of Controls to identify and mitigate hazardous scenarios effectively.
