What is required of a woman who caused a fire that led to the death of a boy she was teaching?

If the woman did not exceed the normal bounds in her actions and was not negligent in saving the boy, then she is not liable. For example, if someone kindled a fire on his own property or on barren land, and a spark flew to his neighbor's property and burned it, or if he irrigated his land and the water flowed to his neighbor's land and flooded it, he is not liable if he acted according to custom and without negligence, because he is not an aggressor. This is the consequence of a permissible act.
