16.1 Where bagged grain or other suitable cargo
                           is utilized for the purpose of securing partly filled compartments,
                           the free grain surface shall be level and shall be covered with a
                           separation cloth or equivalent or by a suitable platform. Such platform
                           shall consist of bearers spaced not more than 1.2 m apart and 25 mm
                           boards laid thereon spaced not more than 100 mm apart. Platforms may
                           be constructed of other materials provided they are deemed by the
                           Administration to be equivalent.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           16.2 The platform or separation cloth shall be
                           topped off with bagged grain tightly stowed and extending to a height
                           of not less than one sixteenth of the maximum breadth of the free
                           grain surface or 1.2 m, whichever is the greater.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           16.3 The bagged grain shall be carried in sound
                           bags which shall be well filled and securely closed.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           16.4 Instead of bagged grain, other suitable cargo
                           tightly stowed and exerting at least the same pressure as bagged grain
                           stowed in accordance with A 16.2 may be used.
