52 Employee Safety Training As part of our Commitment to Excellence Management System (CTEMS), we offer a robust and dynamic year-round training program to ensure operations excellence. With more than 650,000 hours of safety training in 2021 for ~6,100 refining employees, our safety training covers a wide variety of topics, including: • Critical safety procedures, such as energy isolation and control, confined-space entry, fall protection, life-saving equipment and safe work permitting. • Training for excellence in refining operations and mechanical integrity as well as process safety, emergency preparedness and cybersecurity. • Training through computer-based sessions, instructor-led courses, safety meetings and daily safety talks. Contractor Safety Training Valero’s strong safety culture includes not only employees but also contractors. Contractors have adopted the same approach to operational excellence in order to avoid incidents. In fact, contractor companies working at Valero refineries hold a total of 27 OSHA Voluntary Protection Program Stars, after voluntarily submitting to and completing stringent safety audits by OSHA inspectors, as most of Valero’s refineries have done. As outlined in our CTEMS, safety qualifications for all existing and new contractors performing work at our refineries are essential to improve safety performance, efficiency and safety compliance. Contractors hold themselves to the same level of safety training as our employees, participating in more than 1 million training hours in 2021. Pre-screening for Safety Performance and Risks • Contractor companies are pre-screened by a third party to meet or exceed the Valero health and safety expectations. • Contractor employees are trained initially and annually through a reciprocal contractor safety council focused on petrochemical and site-specific health and safety requirements. • Contractors are responsible for ensuring individual craft certifications are maintained. • Comprehensive drug/alcohol testing and disciplinary action programs are required. Operating Guidelines on Contractor Safety Management • Contractor performance is evaluated both during and at the completion of jobs, including preplanning, permitting, auditing and post-job evaluations. • Contractors are expected to meet or exceed Valero health and safety programs, as well as state and federal regulations. • In 2021, we published the Conduct Guidelines for Business Partners, which detail our high ethical expectations of business partners, suppliers and vendors. These guidelines are available on our website at www.valero.com > Investors > ESG > Corporate Governance Documents. 52
