Tank trailer operators prefer simple security systems

Simple appears to be better when it comes to tank trailer security according to those attending the Brenner Tank Technology Focus Conference June 19 and 20 in Fond du Lac WI. For the most part, fleets and equipment manufacturers are struggling with the security issue on their own. Federal requirements may be in the works, but completion seems a ways off.
A typical chemical trailer may require seals at as many as 23 security points. Equipment should be designed so that it is easy to attach security seals to domelids and other hardware. A locking spill dam cover offers one of the best ways to secure openings on top of the tank. Participants in the conference also suggested surrounding discharge outlets and other hardware with small cabinets. Safety and security both would benefit from sealing systems that can be activated while a driver is on the ground. Some of the participants said hardware improvements were needed to make seals more effective. Heavier tabs are needed on manhole covers to make tampering more difficult. In addition, seals should be more resistant to vibration.
John Cannon, Brenner Tank vice-president of engineering, said his company continues to look at a variety of trailer securement technologies, including tamper-resistant air and electrical lines and keypads and magnetic card readers for access to product-handling systems.
