I would like to ask if undetected test piece could be considered as physical hazard in metal detection process.
Process :metal detection
Type of Hazard :Physical
Hazard: undetected test pieces
Cause : malfunction of metal detector
Control Measure : twice a year calibration , every hour test piece detection with and without product
Likelihood: Could Occur
Severity: Product Recall
Siginificant
Thank you
As Tony-C mentions the test piece itself should be encapsulated in a large carrier that makes it highly unlikely to be consumed.
I would also question the rating of your Severity, as the verification test appears to be conducted hourly -- presumably you have an escalation procedure in place that would alert for a hold on the material in question. It seems unlikely you would lose physical control of the test piece from one verification procedure to the next even if it did end up in a package of finished goods.
