Petroleum and aviation industries globally know about the existence of internationally accepted fuel practices and the important need to comply with such technical requirements and operating procedures. The need for this emphasis has been highlighted by occurrences involving actual contamination of, or the potential to contaminate, petroleum products.

The requirements are set out in numerous industry and company policies, standards and procedures (PSPs) covering the entire supply and distribution systems. These PSPs have been developed to safeguard fuel quality and to ensure safe operations from point of manufacture to delivery into fuel tanks.

The various controls and procedures reflect a philosophy of product testing, traceability and segregation to prevent contamination and to ensure that the fuel is on –specification at the point of delivery to end users.
