Fitness-for-Service Task Group

Risk-Based Inspection Software User Group

The refining and petrochemical manufacturing industries are committed to protecting the health and safety of our workers, our contractors and our neighbors as well as the environment in which we operate. Our members continuously look for opportunities to enhance safety and recognize that an effective means to improve process safety performance throughout the industry is to learn from each other. API’s new standards and programs further advance process safety improvements by providing industry with more opportunities to communicate and share experiences and knowledge – vital components of our collective goal to improve process safety performance.

The objectives of the SFPS are to promote safe, healthful, efficient and environmentally sound practices in the petroleum industry, and to initiate, monitor and respond to governmental actions in these areas. The foundation of these activities is the development and maintenance of technical standards and communication and sharing of information related to petroleum industry safety, fire protection, and occupational health.

The Safety and Fire Protection Subcommittee (SFPS) mission is to provide proactive safety and occupational health leadership and expertise to the industry, API committees and member companies. The SFPS seeks to advance and improve the industry’s overall safety and occupational health performance by combining resources to identify and address important public, employee and company issues.

Marketing defined is the wholesale and retail distribution, including tanker truck transportation, of refined petroleum products such as gasoline and diesel fuel to business, industry, government and public consumers.

The Marketing Standards and Recommended Practices that API maintains include the following:
