From Rav Lechem Shevet blog:
“Maakeh and Lo Tasim Damim: Severity of Hazards
So, previously we established that there is a debate whether mitzvas of Maakeh and Lo Tasim Damim are or are not essentially linked, with the consequence to what degree they cover the same cases. Now we’ll take a look at a related question: what cases do these mitzvot actually cover?
The basic case is that brought in the pasuk itself, that of a house with an accessible roof, where the obligation is to add a guard rail. Once we move beyond that case, then the questions begin. We’ll start with the question of severity and then cover other questions in future posts…
Death or Injury
So are these mitzvot concerned with hazards that can cause any injury or just lethal hazards?
Most rishonim understand the gemara(??? ??? ?:, ??.) and it’s 10 tefach limit as implying that these mitzvot are only concerned with hazards which might cause death. As the Meiri says there(?”? ???)
???? ???? ???? ???? ???? ???? ????? ??? ???? ????
On the other hand, there is the baraita of Rebbi Natan, brought several places in the gemara(??? ??? ??:,??? ??? ??.,?????? ??:), and used in discussing cases of potential injury, not death:
??? ??? ???? ????? ??? ???? ??? ??? ?? ???? ???? ??? ????? ???? ???? ???? ???? ?”? ?? ???? ???? ?????
The Sefer Hachinuch(???”?) takes these gemaras at face value and includes nezikin under the mitzva of ?? ???? ????, although he still says that ???? is only concerned with lethal hazards(????).
Rav Soloveichik, on the other hand, explains these gemaras according to the other shita, saying that chachamim made a gezeira extending the issur to include nezikin”
