LISP is a family sprinkler contractor at Lier in Antwerp province with more than twenty-five years behind it, certified by BOSEC as a water-extinguishing installer and publishing its BOSEC certificate, ISO 9001 and per-employee VCA attestations for download — which is more than most firms in the register do. Its own website went live only in mid-2025, which is why the BOSEC register carried no address for it.
