You can use bolt cutters to remove the bolt seal. The jaws of a pair of bolt cutters are designed to compress metal and cut it at its weakest point. This means that if you squeeze them around any metal object, they will eventually break through it - even if the object is thicker than your hands can grip (such as a bolt seal).
1. Place the jaws of the bolt cutters around the bolt seal.
2. Place the jaws of the bolt cutters around the bolt seal.
3. Squeeze the handles of the bolt cutters together until you hear a "click".
If bolt cutters are not in sight, a die grinder will also work, as one driver said: "I think in all my years I've only cut with a die grinder once or twice, just because I or receive I don't have bolt cutters."
However, drivers should never remove any type of safety seal without permission. The recipients at these warehouses will usually have bolt cutters, just ask them for them.
