SHIELD YOUR FUTURE Shield Your Future is a training program for all new employees and contractors. It includes case studies based on real incidents at Phillips 66 and exercises to enhance understanding of safety protocols. These lessons are the foundation and the "why we do what we do" for many of our 10 Life Saving Rules. New employees get materials to review before their first day, and the information is covered as part of orientation. The training is also used as a refresh for existing employees. There are three components of Shield Your Future: 1. Be Aware of Your Actions 2. Stop Work When Unsure 3. Recognize Hazards Hands-on Learning Leads the Way Safety is our first core value. We seek out impactful ways to keep safety at the forefront. In 2021, the Sweeny Refinery created a hands-on safety training experience for more than 850 employees and contractors. The Safety Days program focuses on improving understanding of the Phillips 66 10 Life Saving Rules and Sweeny's safe work practices. It is facilitated by safety teams and operations and maintenance personnel who bring their front-line perspective to the training. Over five weeks, groups of about 50 cross-functional employees rotate through eight hands-on stations, including energy isolation, fall protection, confined space entry, hazard recognition and live fire extinguisher training. Each station meets requirements for annual refresher training, uses prior incidents as examples, addresses frequently asked questions and allows employees to practice what they've learned. Training stations feature a multilevel scaffold, a lock-out tag-out and work permitting room, access to mobile equipment, and retired process equipment for hands-on practice. Employee feedback was overwhelmingly positive, and this critical training has been key to the Sweeny Refinery achieving excellence in safety performance. 10 LIFE SAVING RULES In conjunction with the HSEMS, our 10 Life Saving Rules program is fundamental to Phillips 66's safety culture. All employees are trained on the rules, which are clear, concise and apply to all routine and critical activities. They enhance safety performance and benefit both individuals and communities by preventing injuries. CONTRACTOR SAFETY We involve our contract companies in planning work to be performed to ensure safe practices. Regular communication at all levels is foundational to achieving our mutual goals. Many of our sites have an established Contractor Safety Alliance. These teams include safety professionals, front-line supervisors and leadership from Phillips 66 and each of our contract companies and business trades. They meet regularly to discuss safety issues, performance and lessons learned. Subcommittee members mentor and onboard new contractors and train them on our 10 Life Saving Rules and other safe work procedures. We have contractor-to-contractor audits to support smaller contract companies. The teams include Phillips 66 employees and several contract company leaders. They reach out to workers and address any barriers to safe work. 22 PHILLIPS 66 2022 SUSTAINABILITY REPORT OUR BUSINESSES: TODAY AND TOMORROW ENVIRONMENT AND SAFETY GOVERNANCE STAKEHOLDER ENGAGEMENT
