Location and Positioning

Where your tank is located plays a significant role in determining how easy it is to steal from it. For example, if the tanker is located next a pathway, it inadvertently becomes a vulnerable target. Additionally, where your tank is located in your terminal is also crucial. The tank must be easily visible from the back office however, it should also be hidden away from thieves. While positioning the tank, be sure to place it in way that makes it easy to fill the tank or refuel the vehicles that are dependent on it. Similarly if a mobile tanker is parked inside the terminal and locked away especially after dark, your risk of theft is greatly reduced.


Your facility may already be well secured with anti-theft alarms and gates across the property. However, you can enhance tank security by placing an alarm system within the tank itself. The alarm system can be programmed to send alerts to all concerned personnel if the fuel level drops below a pre-determined level happens.

Anti Syphon Valves and Fuel Caps

Anti syphon valves are essentially one-way valves placed at the tank inlets that allows you to fill the tank but prevent someone from syphoning fuel out. A lockable filler cap or padlocks can go a long way in preventing theft. While these are not guaranteed to stop theft, it can help deter some attempts.


Geofencing a mobile fuel tanker is a technological advancement in GPS fuel management that can help ensure deliveries are only offloaded at predefined areas. The valve of the fuel tanker will only open when the truck is at one of these predefined locations.

Control Switches

If the storage tank makes use of control switches for its operations, make sure these are switched off when not in use. The same principle holds true for electrical supplies, these should also be kept isolated when it’s not required.

Defensive Planning

While perpetrators may arrive at your location, they most likely won’t be prepared to make their way through barbed wire, broken glass and other intruder deterrents surrounding the tank. Defensive planning, while done correctly, can help deny easy access to your tank or terminal.

Security Lighting

For a budget-friendly but effective means to make your tank challenging to target, install security lighting. Preparatory usually like to work in the dark, and by installing security lighting next to the tank, you can notice any dubious activity happening next to it.

Install CCTV’s

While CCTVs alone may not help in warding off thieves, they are a useful security measure, especially if they are combined with other security features.


Arguably, the most straightforward and perhaps even the most useful thing you can do to prevent theft from your on-site premises is to place warning signs. While thieves may ignore such signs, these can help alert by-passers when suspicious activity occurs.
