Clever solvedIn production facilities the explosion protection means are designed as stand-alone systems and therefore installed
with process independent sensors.

Field connection box FAB-3
for conditioning MEX-3 signals
The explosion multi-sensor MEX-3 recognizes the hazard at an early stage by detection of pressure rise (dp/dt) or a
static pressure threshold.

Explosion Suppression EN 14373
Explosion suppression and
explosion isolation on grinding mill
Nipped in the budExplosion suppression systems are designed to prevent the generation of high pressures by fuel-air explosions in
vessels. Explosion suppression systems do not prevent an explosion from occurring but mitigate its effects on the
protected equipment. The flame front is extinguished at the early stages of the explosion development, considerab-
ly reducing the risk of post-explosion fires and secondary explosions events.

Focused relievedExplosion venting devices are designed to open at the incipient stages of an explosion event and
are sized to ensure that the rising pressure does not exceed that of the pressure shock resistance of
the vessel.
Explosion Venting EN 14797
Flameless explosion
venting
Explosion venting using curved
rupture discs
Vertical explosion venting Rupture disc with isolation
Notice:
After the explosion pressure has been released by a venting device, it is likely that flame will still be present
which can then lead to a post-explosion fire or secondary explosion occurrence. To avoid subsequent damage
fire protection systems are highly recommended.

Explosion Isolation EN 15089
Well-delineatedIn order to reduce the risk of flame transfer to connected plant items and processes, explosion isolation devices can
be employed. Mechanical devices such as fast acting valves also prevent pressure waves damaging connected plant.
Suppressant barriers are rapidly established (even on very large ducts) and effectively extinguishing the propagating
flame front.
Some conveying and process feed systems also provide effective explosion isolation under the EN15089 directive.

Our vision is, to make the world a safer place
UTC offers safety solutions worldwide by using explosion and fire
protection technology
From product development, safety system design through to
commissioning and maintenance of explosion protection
systems, our engineers and technicians take care of per-
sonnel safety and protect industrial installations around
the globe.
INCOM Explosionsschutz AG is a UTC group company
(www.utc.com), integrated in the Fire and Security
division. UTCFS is an important company in the world-
wide business of safety engineering with organisations
in 35 countries and 47‘000 employees.
We concentrate on the safety system design and turnkey
delivery of fire and explosion protection systems for pro-
cess plants. Furthermore our region-wide service network
from Hamburg to Naples and from Paris to Budapest guaran-
tees short travel times for our technicians therefore delivering
a fast response time and low maintenance costs.
