8 Biblical Commandments relating to accident prevention:
1) Build a fence around the roof of a house (Devarim 22:8) This also extends to command protecting against any dangers.
2) Do not place blood on your house (Devarim 22:8), the negative commandment for not protecting against danger
3) Watch yourself exceedingly (Devarim 4:9) The Rambam quotes this (possibly based on Berakhot 32b) as a positive mitzva to avoid danger.
4) Do not stand idly by while your friend’s blood is spilled (Vayikra 19:6) This commands protecting another who is in danger of death.
5) Do not destroy (Devarim 20:19) The Talmud sees this verse (in context referring to destroying fruit trees to build a ramp during a siege) as relating to all forms of pointless destructiveness, including doing things that physically harm our bodies.
6) Don’t put a stumbling block before a blind man (Vayikra 19:14) Most see the simple reading of this verse as a metaphor for giving bad advice or causing another to sin.
7) Damages caused by leaving an open pit (Shemot 21:33-34) This is a mitzva on courts to judge cases involving compensation for damages. This is limited to damages to animals in public places.
8) Returning a lost object to a friend (Devarim 22:2) -- and, the gemara infers, certainly his body. To save one in danger is to return him his life and health. Rambam also sees this as the command for doctors to heal.

5 Jewish values relating to accident prevention
1) Preserving life, ours and othersa cardinal Jewish value, overriding most commandments in the vast majority of cases.
2) Forseeing future situations: Rabban Yochanan ben Zakai asked his five greatest disciples to investigate the proper path for a man to take in this world. Rabbi Shimon said, "He who sees ahead." (Pirkei Avot 2:9) Efficient accident prevention means taking the time to think ahead, deeply and systematically.
3) Taking responsibility, as Hillel says, "If I am not for myself, who will be for me? If I am only for myself, who am I? If not now, when?
4) Looking out for others, as Rabbi Akiva says, "Love your neighbor as yourself," this is a general principle of the Torah. This focus on helping and thinking about others is the central point of Jewish ethics' emphasis on modeling ourselves after the Divine.
5) Patience
