CLEANING AND THE INSPECTION OF HDPE AND MS LINED DRUMS

1.0    PURPOSE:
    
        To describe a standard operating procedure for the cleaning and  the inspection of HDPE and MS lined drums. 
    
2.0    SCOPE:
    
        The  SOP  describes in detail the method of cleaning and  the inspection of HDPE and MS lined drums.
    
3.0    RESPONSIBILITY:
    
        The  responsibility  of  getting the drums cleaned as  per  the standard operating procedure  lies  with  the staff  of the rank not lower than operator of production department.
    
        The responsibility of preparing, reviewing and approving the SOP lies with the Officer (Production), Head of Production and Head of QAD  respectively.
    
4.0    METHOD:
    
4.1    DEDICATED DRUMS

4.1.1    The  drums are cleaned by the solvents for which the drums  are   intended  to  be used.  The washings are checked  for  moisture  content by quality control department.
 
4.1.2    After getting the satisfactory report of moisture content  from  quality  control  department,  the supervisor requests  the  QC  personnel  to check the drums physically and QC  chemist  after   checking the drums physically for foreign matter, certifies the  drums in the prescribed format.

4.2    NON-DEDICATED DRUMS

4.2.1    The drums are rinsed with the solvent which is to be filled  in   the drums.  The rinsings are sent to quality control department  for G.C. analysis (check for the absence of foreign peaks).
 
4.2.2    After  getting the G.C. results the quality  control  in-charge  will decide whether the rinsings are sufficient or not.  If the  rinsing  is not sufficient the supervisor will be asked  to  do   more  rinsings and send samples to QC department for  analysis. This step will be continued till the G.C. results are satisfactory.

4.2.3    After  getting  the  report, the supervisor  will  request  the  quality  control  department to inspect the  drums  physically. The  quality control chemist after inspecting the drums  certifies in the prescribed format.
 
    NOTE:  
        
1.     The  supervisor  should assure that the lids of the  drums  are  always closed 
        after cleaning is over.
                
2.     The  dedicated drums used for solvents have to be checked  only physically.
