Can anyone help to answer what is the corrective action for conduct Metal Detector rejection test at the frequency longer than what's written in the SOP, like it's required every 1 hour, however the operator forget and does it more then 1 hour?
Moreover, for the start up test, can the metal test strips embedded with product be conveyed through the Metal Detector instead of only metal test strips alone?
Agree with running all the products made after the last good run, time consuming, but this is how production/management people will learn that Metal detection is not something that they should take lightly.
But, in your written procedure, you should have some wiggle room too to conduct the test, say +/- 15 mins, the metal detector test must be carried out. Unless of course you have dedicated personnel doing the metal detector test, then the exact hourly should no longer be missed.
So... when you pass the test strip on its own on the metal detector, you're not only checking the working condition of the metal detector but you're also checking the condition of each test strip, that they are actually getting detected by the machine and still has the metal in them. So checking the test strip on its own is a good practice before you embed it on a product.
