When securing heavy cargo with transport chains and ratchet binders, what must be done with the loose tail end of the chain?

1. Tie or wrap the loose chain securely to the tensioned binder so it cannot flail, hit other vehicles, or catch under the trailer tires
2. Leave the tail hanging free so it can be inspected quickly at the next stop
3. Coil the tail and rest it loose on top of the load
4. Pass the tail under the trailer and leave it lying across the axle
