Musar for Bava Kamma 124:12

We find a similar discussion in Bava Kamma (62b), in conjunction with rules about where to place the Chanukah lights. First we are told that any damage due to sparks emitted from the anvil is the smith's responsibility. We are also taught there that if a camel laden with flax walks in the public domain near which Chanukah lights are burning, the owner of those lights is not responsible for damage sustained by the flax (at least according to Rabbi Yehudah). If the lights causing the damage did not serve a מצוה purpose, everybody agrees that the owner is responsible. The discussion about possible damage caused by the Chanukah lights is also mentioned in Shabbat 21b, where most of the details about Chanukah observances may be found.
