Hazardous Waste Management
Jubail, Saudi Arabia, 2015

6. POST FIRE INCIDENT SCENARIO
Potential Causes
 No active fire protection, e.g. water mist
system.
 No passive fire protection (inside or
outside, e.g. wall cladding.
 Lack of fire prevention.
 No automatic fire detection, e.g. thermal
detector camera.
 Flammable furnishings used.
 Electrical and sensitive equipment non
compliant.
 Poor maintenance/upkeep sensitive
equipment.
 Human behaviour, e.g. arson (by people)
 Lack of fire training
Effects on People, Assets &
Environment
 Breath the smoke and toxic gases.
 Drop part of the cladding blaze outside.
 Involvement of the beside building as fire and
smoke.
 To compromise the stability building.
 Damage and Downtime the asset.
 Difficult to reach by Fire Service Equipment.
 Environmental involvement

7. “The Fire Triangle of Combustion”
Heat
For a fire to survive, it relies on the
presence of the three elements of the “Fire
Triangle”. Oxygen, Heat and
Combustible material.
The removal of any one of these elements
will extinguish a fire.
A high-pressure Water Mist system goes
further.
It attacks two elements of the fire triangle -
Oxygen and Heat

8. TRADITIONAL SPRINKLERS
SYSTEM
To fight a fire, a traditional sprinkler
system spreads water droplets over a
given area, which absorbs heat to cool
the room. Due to their large size and
relatively small surface, the main part
of the droplets will not absorb enough
energy to evaporate, and they quickly
fall to the floor as water.
The result is a limited cooling effect
and damage the assets.
WATER MIST SYSTEM
1) Cooling effect - Effect Heat-absorption:
(the evaporation of 1 kg of water produces an
absorption of heat equal to 583 kcal/kg = 2,44
MJ/kg).
2) Rapid suffocation (Oxygen displaced from
the fire)
3) Controlling smoke and toxic gases
(combustible gasses displaced from the
fire)
4) Radiant Heat Blocking
 Uses 90% less water than traditional
sprinklers.
 High Pressure work (up to 150 Bar)
 Low Pressure work (8 Bar = 115 PSI)
Active Fire Protection:
Water Mist Compared to Traditional Sprinkler System

9. Water Mist Fire Suppression Mechanism
High Pressure
Water Mist
(HPWM)
Conforms with
NFPA 750
In accordance
with
CEN TS 14972,

10. Fuel/Oil Fuel/Oil
90% less Water
Reduce the Oxygen,
contain and suppression
the fire
Fuel/Oil
More Water
Fire spread effect
Advanced
Water Mist System
Water/Foam traditional
Sprinkler System
 Traditional foam sprinkler : more water raises fuel and causes fire spread effect
 Advanced Water Mist System: less water fuel and fire contained, but reduce oxygen and contain the fire
 The System uses 90% water less, mean longer suppression time than traditional
system.

works with fuel or oil

11. Water Mist System Cooling Effect
The small droplet size
has large reaction surface
which makes the
absorption of heat very
efficient.

High Pressure Water Mist must have less than 1000

μm = 0,001 mm)
