  Until 2018, the lim­ited fire­fight­ing means in the SPS com­plex largely ex­posed it to the con­se­quences of self-ig­ni­tion or ac­ci­den­tal fire. In 2015 the SPS Fire Safety pro­ject was launched with the ob­jec­tive of im­prov­ing life safety and prop­erty pro­tec­tion by de­ploy­ing a whole set of au­to­matic ac­tions to pro­tect SPS in case of fire out­break. If noth­ing was done, an un­man­aged fire could be a threat to lives of those work­ing un­der­ground and could mean los­ing a vast ma­jor­ity of the SPS ma­chine and its equip­ment. In 2020, CERN has com­pleted the con­sol­i­da­tion of its SPS fire safety sys­tems. Among these, a water based sprin­kler sys­tem, fol­low­ing prin­ci­ples of stan­dard in­dus­trial de­sign but cus­tomized and tai­lor-made for SPS and its ir­ra­di­ated areas, is ready to op­er­ate. The sys­tem must take into ac­count lim­i­ta­tions re­lated to the pres­ence of frag­ile ac­cel­er­a­tor equip­ment, ra­dioac­tive zones, in­te­gra­tion con­straints and com­ply with Eu­ro­pean norms, in par­tic­u­lar EN12845. This paper pre­sents the risk as­sess­ment, our ex­pe­ri­ence from the plan­ning and in­stal­la­tion phase while dis­cussing the cus­tom-cho­sen and ra­di­a­tion tested equip­ment to end up with the lessons learned and out­look for the fu­ture.
