Commercial fuel oil storage is now subject to greater scrutiny with the introduction of a fuel certification scheme by the Federation of Petroleum Suppliers (FPS).

Developed in conjunction with tank hygiene specialists OTS TankCare and Scarletts Systems, the scheme will enable FPS members to safeguard themselves against the potential risk and any consequential claims, resulting from post-delivery contamination. Mark Askew, chief executive of the FPS, said: "Fuel quality has moved up the agenda. With the introduction of new biofuels and the current FAME content up to 7%, better housekeeping is essential throughout the supply chain.

"The FPS scheme sets standards for fuel testing, cleansing and best practice for preventing contamination by water, particulates and microbial growth in tanks."
