leading causes of fires and explosions in the industry.
"Hazard monitoring is about preventing explosions that will hurt people and ruin facilities," explains
Anthony Leali, 4B Components business development
manager. "We want to monitor the source of ignition."
For example, hazard monitors track the temperature, speed and alignment of equipment, like the
bucket elevator and conveyor, to ensure it doesn't malfunction and overheat.
Maintenance is equally as important as the installation of a monitoring system. Because hazard monitors are
exposed to a wide range of ambient temperatures, weather
and harsh environments, Leali recommends performing regular maintenance checks. Commissioning and
periodic maintenance testing can be accomplished using
hand-held testers to perform 100 percent functional tests
on sensors and hazard monitoring systems.
The hand-held tester will provide real-life conditions to verify hazard monitoring operation and, when
connected to a cloud-based monitoring and maintenance system records the date, time and operator notes
of the test in real time. Hazard monitoring status,
system analytics and maintenance test results can be
viewed from any web-enabled device.
Dust collectors 101
Hazard monitors go hand in hand with dust collection systems. It's key for mills to know what types of
dust they're producing, and to take a tailored approach
to controlling it.
■ Bag collectors
Baghouse dust collectors utilize non-woven felt filter fabric supported on wire cages. Dust collects on the
outside of the bag, and compressed air is pulsed to the
bag interior to back-flush dust off of the filter media in
the opposite direction of collection airflow. Bag media
is very tolerant of dusts that tend to agglomerate or
form into a hard cake, as the flexing action of the fabric breaks the cake and enhances dust cake release.
Bag filters are a good choice for feed mills that
handle products that agglomerate or react with moisture
to form a crusty cake. Bag configurations that utilize a

OSHA requires feed mills with storage capacities
of 1 million bushels or more use hazard
monitors to track the temperature of potential
ignition sources. 4B Components
