Configuration of Fire Zones and Outdoor Hydrants

• The configuration of fire zones depends on the zone's surface area and intrinsic risk level.
• Types of zones:
  • A: ≥ 300m², low to medium risk
  • B: ≥ 1000m², medium risk
  • C: ≥ 2000m², medium to high risk
  • D or E: ≥ 5000m², high risk

Installation of Outdoor Hydrants

• The number of outdoor hydrants required is determined by the size of the protected area.
• Each hydrant should cover a radius of 40m, measured horizontally from the hydrant's location.
• At least one hydrant should have a 100mm outlet, preferably located at the entrance.
• The distance between the hydrant and the exterior of the building or protected zone should be at least 5m.

Water Requirements and Autonomy

• The water requirements for each zone are determined by the type of establishment and its intrinsic risk level.
• Water requirements:
  • A: 500L/min, 30min autonomy
  • B: 500L/min, 30min autonomy; 1000L/min, 60min autonomy; 1000L/min, 90min autonomy
  • C: 500L/min, 30min autonomy; 1500L/min, 60min autonomy; 2000L/min, 90min autonomy
  • D or E: 1000L/min, 30min autonomy; 2000L/min, 60min autonomy; 3000L/min, 90min autonomy
• Notes:
  • When storing combustible products outside, add 500L/min to the water requirements.
  • The minimum pressure at the hydrant outlet should be 5 bar.
