One may break the cap on the mouth of a cask of wine or of fish broth; only he shall not intend to make a gutter. You may not open locked jars; Rabban Shimon b. Gamliel declares it permissible. One must not extinguish a log because of the dampness, lest it smoke the house; but if one does it, lest it burn the dish, behold, it is permitted for him.
