Explosive moments: the spark often occurs at unexpected locations
Typical applications where explosionrisks exist:
• Mills
• Mixers
• Conveyors
• Elevators
• Pneumatic conveyors
• Silos, bunkers
• Sieves
• Spray dryers
• Fluid bed dryers
• Filters, cyclones
• Shredders
• Reactors
• FIBCs (Big Bags)
• Aerosol Fill Rooms
• And many more!
How can an explosion be initiated from a dustor gas air mixture?
When a flammable mixture occurs simultaneously with sufficient
oxygen and an ignition source. This is the classic fire triangle.
Eliminate any one of these and an explosion will not occur.
Typical ignition sources include:
• Hot surfaces occurring in mills, mixers, fans, etc.
• Mechanical sparks (friction, grinding, impact)
• Electric equipment
• Smouldering combustion
• Electrostatic discharges (cone discharges, brush discharges,
propagating brush discharges and sparks)

Reducing the consequences of explosions
Explosion suppression installations are designed to prevent the generation of high
pressures by fuel-air explosions in vessels. Explosion suppression installations do
not prevent an explosion from occurring but mitigate its effects on the protected
equipment and personnel. The flames are quenched in the early stages of explosion
development. In this way personnel in the vicinity of the installation are protected
from being hurt, and destruction of the installation is prevented.

Extinguishing post-explosionfires
After an explosion a fire in vented
installations is not uncommon. This is
particularly common if explosion doors
do not close after operation.
To avoid further damage by a post-explosion
fire, fire protection systems are installed
(Aquasafe®, powder, CO2, Argonite®,
FM200®, etc.). The choice of the fire sup-
pressant is based on the product
properties. The fire is detected early
during its development using temperature
sensors which are unaffected by pollu-
tants and will automatically extinguish
the fire.

Avoiding explosion transmission
To prevent pressure waves and/or flames being mitigated to other plant areas,
isolation devices must be fitted such as:
• Extinguishing barriers (chemical)
• Fast acting slam shut slide valves
• Ventex-valve
• Diverter with extinguishing barrier
Explosion isolation of a filter designed to withstand 10 bar over pressure
The dust control devices of Dustalert allow for continuous monitoring and indication of dust emissions in dust collectors as well as the early detection offilter damage
Installed in conjunction with explosion protection systems, dust control devices are mounted on the clean airside
of the filter. The potential presence of an explosive dust-air mixture on the clean airside is extremely alarming as
normally no constructive protection measures are applied on this side. An explosion caused by the fan as potential
ignition source could therefore destroy the equipment. Effective monitoring and early detection of hazardous
dust concentrations offer excellent protection against explosions.
The additional control of the filter bags provides extra protection for the environment.
• No optics
• Practically maintenance free
• Simple mounting
• Dust emission trend analysis and monitoring of filter damage
• Innovative microprocessor controlled sensor (patented TriboACE®-method)
• Applicable for several types of filters and ducts
Dust control device DS-10, digital output
Dust control device DS-30, 4-20 mA output
Dust control device DA-50 for moist products and high temperatures
Kidde Explosion Protection sensor technology
Such a control can be achieved by:
• Rate of pressure rise or static pressure
• Temperature
• Flames
In production facilities the protection devices must be installed with process
independent sensors. The explosion multi-sensor MEX-3 can detect potential
hazards at a very early stage in the explosion process.
Thermal explosion
This process is referred to as
runaway reaction or thermal
explosion. This possibility can
arise when:
• materials become thermally
unstable
• strong exothermal reactions
are maintained
• there is an unacceptable
increase in heat production
• there is an unacceptable
accumulation of the reaction
potential
• insufficient heat of reaction
is removed
Controlling spurious events
Several measures can be used
to prevent unwanted events,
such as the concepts of mea-
suring, control and regulating
technology, shutdown systems,
emergency cooling or organi-
sational measures aimed at
eliminating potential hazards.
