Which fire protection system is convenient according to the type of fire risk ?

Fire protection systems are designed according to the type of fire risk.

Their design varies according to 4 major characteristics according to :

  • The risk to protect allows general intervention or requires local intervention;
  • Post-discharge residues are admissible or not;
  • The protected area is usually occupied or not by users;
  • The sealing of the room to protect.

Decision tree – Class A fires (not deep seated)

Class B fires

Flammable liquids
