18.9.1 Any cargo sampling shall be conducted under
                           the supervision of an officer who shall ensure that protective clothing
                           appropriate to the hazards of the cargo is used by everyone involved
                           in the operation.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           18.9.2 When taking liquid cargo samples, the officer
                           shall ensure that the sampling equipment is suitable for the temperatures
                           and pressures involved, including cargo pump discharge pressure, if
                           relevant.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           18.9.3 The officer shall ensure that any cargo
                           sample equipment used is connected properly to avoid any cargo leakage.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           18.9.4 If the cargo to be sampled is a toxic product,
                           the officer shall ensure that a "closed loop" sampling system as defined
                           in 1.2.15 is used to minimize any cargo release to atmosphere.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           18.9.5 After sampling operations are completed,
                           the officer shall ensure that any sample valves used are closed properly
                           and the connections used are correctly blanked.
