Hi everyone!
I wish to clarify on something. We are from a sugar refinery and one of our CCP is on the magnet traps whereby we shall determine the strength of the magnets using a gauss meter in a pre-determined frequency.
We also practise a cleaning system of those trapped magnet traps (not a part of our CCP). We shall remove the magnets, clean them, collect the sediments trapped by the magnets, weigh and record the quantity in a log book twice daily. This is our internal control so that we are able to refer on the log books shall there any issues in future. We do have a max limit for the magnet traps collected where if the limit is exceeded, we should take an immediate action. The question is : currently I need to study back on the limit as we found that initially set limit might be too stringent (the limit was set by earlier personnel many years ago).
I have done a study where I have gathered sediments collected each day for a period of time, weighed them and plot a graph to determine the maximum limit that has been achieved. Would like to clarify here, is there any reference of limits for this magnets collected during cleaning or it is totally up to the company to set their own limit based on the study? Aside, any other important aspects that I should also consider while doing this study?
Thank you in advance!
