ducting design and equipment type
can be discussed. Keep in mind that
different dusts require different solutions
when selecting and configuring
equipment. And, of course, combustible
dusts require adequate means of
protection, such as explosion venting
or suppression systems.
" Unfortunately there's not a one-sizefits-all
solution. Each material, each
process and each facility has different
dust-collection and dust-safety needs
and requirements, " explains Caulfield.
Other issues to keep in mind
However, experts warn that even a
properly selected, sized and installed
dust-collection system is not enough.

Safety Monitoring Filter (iSMF) requires

Other steps are needed to achieve
complete compliance, and to protect
employees and assets.
Housekeeping is the first line of defense
in fighting the dust battle, no
matter the type of dust. " Fugitive dust
is often a problem because it collects

Do you have flows up to
9,000 GPM (2,000
m3/hr), heads up to
720 ft (220 M), speeds
up to 3,500 RPM, and
temperatures up to 600°F
(315°C)? Then you need Carver Pump
API Maxum Series muscle!
Specifically designed to meet the needs of the
Hydrocarbon Processing Industry, the API Maxum
Series is fully compliant with API 610 Specifications.
Manufactured in 35 sizes, standard materials of
construction include S-4, S-6, C-6 and D-1, with
others available upon request. Standard features
include a 682 Mechanical Seal compatible seal
chamber and the ability to operate up to 400°F
without external cooling. Options include a variety
of mechanical seals, lubrication/cooling arrange -
ments, auxiliary protection devices and certified
testing capabilities. Whatever your requirements,

ing and flat hanging lights, " says Scott.
" Anywhere that dust can accumulate
out of sight is a problem because if
there is a fire or explosion in a facility,
the initial explosion shakes the building,
which releases the dust sitting on
these surfaces and, as the flames from
the initial fire tear through the facility,
this released fuel (the fugitive, dispersed
dust) can be ignited, creating
additional explosions. For this reason,
it is imperative to collect dust at its
source and keep up with housekeeping
to prevent it from accumulating
on these surfaces. "
While dust collection equipment is
often viewed as a necessary evil, Daniel
Novicky, sales engineer at Aerodyne
Environmental, Inc. (Chagrin Falls,
Ohio; www.dustcollectorhq.com), says
there are ways to minimize the expense
associated with it. " Look for equipment
that limits downtime, reduces the frequency
of maintenance and the cost
of working on that equipment, as well
as well-made equipment that does not
need frequent replacement. "
Worker training is also very imporCreating

tant. " OSHA interviews your employees, "
says Scott. " They want to know
if the workers are aware of, trained
about and know how to handle issues.
So training your employees on hazardous
dust handling goes a long way
toward avoiding OSHA citations and
loss related to explosions. "
