#3 | Fire extinguishing waters – Constrained spaces

Contain fire extinguishing water vertically to the building

This approach should only be considered if it is impossible to contain the extinguishing water outdoors because it involves manual installation which can be difficult depending on the circumstances of the fire
Provide for the complete sealing of the networks (valves, sealing balloons, sealing plates)
Identify all openings
Calculate the retention height for each opening
Reinforce passive protections as much as possible: walls, speed bumps
Position the removable protections near each opening
