9.1 The retained sample should be kept in a safe
                           storage location, outside the ship’s accommodation, where personnel
                           would not be exposed to vapours which may be released from the sample.
                           Care should be exercised when entering a sample storage location.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           9.2 The retained sample should be stored in a
                           sheltered location where it will not be subject to elevated temperatures,
                           preferably at a cool/ambient temperature, and where it will not be
                           exposed to direct sunlight.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           9.3 Pursuant to regulation 18.8.1 of Annex VI
                           of MARPOL 73/78, the retained sample should be retained under the
                           ship’s control until the fuel oil is substantially consumed,
                           but in any case for a period of not less than 12 months from the time
                           of delivery.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           9.4 The ship’s master should develop and
                           maintain a system to keep track of the retained samples.
