UIP technical note on marking of wagons flushed with nitrogen

Guidelines developed by UIP Topical Committee Safety

 

In the past, according regional sector agreements and non-existing legislative rules, the marking of wagons flushed with nitrogen was different. Different markings may result in fatalities (injured or killed people) when entering the tank. In order to display the risk to everybody who is about to enter the tank as well as to give the operator clear information that a tank is flushed with nitrogen and ready for filling, a clear marking is necessary. This UIP Technical Note is drafted by the UIP Topical Committee Safety and provides for a Europe-wide instruction on how to mark a tank wagon flushed with nitrogen.
