When a ship shall have entered a port or place of refuge or shall have returned to her port or place of loading in consequence of accident，sacrifice or other extraordinary circumstances which render that necessary for the common safety，the expenses of entering such port or place shall be admitted as general average；and when she shall have sailed thence with her original cargo，or a part of it，the corresponding expenses of leaving such port or place of refuge consequent upon such entry or return shall likewise be admitted as general average．

When a ship is at any port or place of refuge and is necessarily removed to another port or place because repairs cannot be carried out in the first port or place，the provisions of this Rule shall be applied to the second port or place as if it were a port or place of refuge and the cost of such removal including temporary repairs and towage shall be admitted as general average．

The cost of handling on board or discharging cargo，fuel or stores whether at a port or place of loading，call or refuge，shall be admitted as general average，when the handling or discharge was necessary for the common safety or to enable damage to the ship caused by sacrifice or accident to be repaired，if the repairs were necessary for the safe prosecution of the voyage，except in cases where the damage to the ship is discovered at a port or place of loading or call without any accident or other extraordinary circumstances connected with such damage having taken place during the voyage．
