I have been tasked with researching the sealed/locked metal detector reject boxes and providing justification for implementing one within our current process. I have not found a requirement for having a sealed box at this point (only manufacturer recommendations stating rejected product should go into a sealed box). I am curious who uses a locked box for their metal rejects and justifications for using one. Our current process has the rejected material blown off the conveyor down a chute into a lined box label waste. Current items of support I see are:
1.) Eliminate the risk of rejected product being reintroduced improperly
2.) Eliminate the risk of rejected product getting discarded before an investigation can occur
3.) Eliminate the risk of the metal reject's removal by an operator intentionally put into the product stream or hiding the reject from superiors
I appreciate all your help.
