When any property of an estate is in such condition as to be in imminent danger of loss or destruction or loss in value, the executor or administrator may make such expenditures as are reasonably and prudently required to avoid such loss, destruction, or loss in value until he can obtain consideration of the matter by the court, and on approval of the court such expenditures shall be allowed as expenses of administration. The court may by order authorize such further expenditures to prevent loss, destruction or loss in value as the interest of the estate requires, and shall allow them as expenses of administration.
