Reasons for being on closeout may be:
• damaged by forklift
• damaged in shipping/transit
• short in length – had to have some cut off
• one/both ends damaged/nicked/scuffed
• good condition, but re-boxed
Shrink wrap can burn.
If heat is applied incorrectly, shrink wrap can ignite into open flame. It can also drop down onto other combustible material and cause secondary ignition and fire. If at any time you observe the wrap on fire immediately stop what you are doing and carefully inspect the area where you are working for a possible fire. Keep a fire extinguisher available at all times.
