These tamper evident stickers will help alert you and your employees to any unauthorized entries into the fuel pump cabinets. All point of access to fuel pumps (including diesel and kerosene) are equipped with tamper-evident stickers. If someone attempts to remove the sticker, it will show "VOID" across the front. Each time the pump is opened (for maintenance by a tech, adding receipt paper, etc.) the sticker must be replaced on the pump and in the control log. The control log is updated with the reason the pump was opened.
