GRAIN
HANDLERS INVEST IN WORKER SAFETY FOR RAIL OPERATIONS
More and more grain handlers have been installing
equipment to protect employees who are working 14 feet
up atop covered hopper cars from falls, though the approach
varies from company to company. Fall protection units
often are custom-designed to fit the unique aspects of
the job site and the work performed.
One example is Maumee, OH-based The Andersons Inc.,
which has installed fall protection equipment at several
of its elevators in a four-state region. Perhaps the most
unusual installation was completed over the winter of
2000-01 at the company's 5.5-million-bushel rail-loading
terminal at Delphi, IN (765-564-6130/www.andersonsinc.com),
which serves as both an indoor and outdoor system.
The Delphi facility loads 50-, 75-, 85-, and 100-car
trains on the Norfolk Southern at a rate of 55,000 bph,
says Operations Manager Bob Marlow.
The spout for the facility's bulk weigh loadout system
is located in a metal rail shed, which does a good job
of holding down dust emissions. However, the speed of
loading railcars, which are pulled by locomotives through
the shed in five-car strings, requires a six-worker crew,
including one on top of the rail-cars. This worker monitors
the flow of grain into the railcars and then closes the
hatches and seals them.
"The first and most obvious reason for installing
fall protection equipment is to protect our employees,"
Marlow says.
The Andersons looked at several systems on the market
before settling on a patented, truss-supported I-beam-and-trolley
type unit designed, manufactured, and installed by Fall
Protection Systems Inc., Florissant, MO (877-972-0400/www.fallprotectionsystems.com).
The system stretches 300 feet in length, nearly long
enough to cover an entire five-car string, with portions
both inside and outside of the loadout shed. The section
inside the shed is mounted directly on the shed structure,
while the outdoor sections are supported by 30-foot-tall,
heavy-duty steel poles in concrete bases. The system is
rated to handle up to four workers at once.
With the I-beam suspended overhead, workers simply
don a full body harness and attach to the self-retracting
lifeline, which is connected to a trolley that can roll
the full length of the I-beam without interruption, since
the beam is virtually seamless.
"We preferred an I-beam system to a cable-type
system for several reasons," Marlow explains. "We
felt that with the conditions we have during the winter,
there was a danger of icing on a cable, which could interfere
with operations.
"The primary thing, though, was that if we did
have a fall, we would have to take the entire cable-type
system out of service until it could be repaired and tested.
With an I-beam and trolley, we would have to take the
individual harness and lanyard out of service but not
the entire system."
Also, with rigid beam systems, the beam does not stretch
and, unlike a safety cable, has no elastic memory. Therefore,
falls normally are limited to less than two feet, and
when a fall is arrested, secondary falls due to bouncing
are eliminated.
In practice, The Andersons only allow two workers
on top of railcars at a time under most circumstances.
Catwalk Modification
The Andersons has a reputation of designing new technology
or modifying existing technology to suit its needs.
In this case, The Andersons' in-house engineering
department in Maumee designed a 300-foot-long catwalk
to run the length of the fall protection unit, parallel
to the loadout siding. Andersons employees installed the
catwalk, which is mounted adjacent to the Fall Protection
Systems unit.
"The catwalk allows our crew to close and seal
a hatch, step off the car, wait for the next one to roll
past, and step back onto the car safely, all while the
string of cars is in motion," Marlow explains.
This system required some compromises in its design,
since covered hopper cars vary somewhat in height - in
some cases the worker must step up onto the catwalk from
the railcar; in others, the worker must step down. However,
having the Fall Protection Systems unit in place allows
the worker to do this safely.
Railcar Wash
Fall Protection Systems Inc. also was the vendor of choice
far fall protection equipment at the other end of the
Corn Belt at Frito-Lay Inc.'s 3-million-bushel corn receiving
elevator in Gothenburg, NE.
This unit, however, is not used for railcar loading
but as part of a "wet cleaning" station for
railcars, located some distance away from the elevator
structure.
"We are basically a single-car shipper, and we
have a pool of covered hopper cars from the Union Pacific
(UP) that we use to ship food-grade corn to our chip plants,"
says Operations Manager Christian Freberg.
Normally, these railcars cycle back and forth between
the chip plants and Gothenburg and require relatively
little maintenance and cleaning in between round trips.
However, during peak demand seasons for Frito-Lay products
such as during the summer or holidays, the company must
bring in "free-runners" from the UP to haul
the extra corn needed.
"Often, it's hard to tell what the railroad had
in those cars before, and we need to get them up to food-grade
standards," Freberg says. "We can do some dry
cleaning in our loadout shed, but we need the outdoor
station for wet cleaning the cars with pressurized water,
bath inside and out."
There was never any question that there would be fall
protection equipment at the station, not just because
of the usual hazards associated with working on top of
railcars, but because of the additional potential fall
hazard associated with handling water under high pressure.
Last autumn, Fall Protection Systems installed a 120-foot-long
overhead I-beam system, suspended from a 30-foot-tall
support pole at either end, with the poles firmly mounted
in concrete bases. The system is rated to handle two workers
at once and stretches the length of two railcars.
In addition, this installation includes a metal staircase
mounted on one of the two support poles, which allows
workers to climb on top of the railcars safely in all
weather.
"'We've had no problems with the system so far,"
Freberg reports. "It has enabled our employees to
clean up railcars in a safe manner within OSHA guidelines."
Two-Spout Coverage
An Iowa cooperative took yet another approach to fall
protection at a 7-million-bushel concrete rail loading
elevator in Vincent, IA.
The New Cooperative Inc. facility (515-356-4185) loads
100-car unit trains on a Union Pacific branch line through
two separate loading points simultaneously. The loading
points are gravity spouts outfitted with Kyoat metering
systems. Using automated loadout controls from two points
allows workers to load a five-car string in 15 to 20 minutes.
New Cooperative installed a fall protection unit during
the fall and winter of 2000-01 and, again, turned to Fall
Protection Systems because of its I-beam design. "If
someone falls on a cable system, we would have to take
it out of service until it could be retested," says
Dennis Knight, director of safety and loss control.
The Vincent elevator is one of six rail loading sites
the coop operates, all of which will have fall protection
installed by the end of 2002. "We built at Vincent
first because it was the most potentially dangerous,"
Knight says. "Because of the way the loadout is set
up, workers would have to climb up the side of the railcar
and stay on top until the car was ready to move."
The system is a lengthy one, spanning a little over
300 feet or a little more than five railcar lengths, in
order to cover both loadout points. In addition to the
I-beam system, Fall Protection Systems designed and installed
two stairway accesses at each loadout location, and New
Coop mounted electronic loadout controls at the top of
each staircase. This allows workers to control spout operation
without having to stand on top of the railcars, though
they still need access to railcars in order to open and
seal hatches.
"We also bought individual harnesses for each
worker, with shoulder pads for summer use," Knight
says. "Some of our employees have a second harness
designed to fit over bulky clothes during the winter.
"At first, some of our employees were reluctant
to use the system, but when they saw how it freed up their
hands to work on top of railcars, they were more accepting.
We load in ice, snow, sleet, rain, and hail, and once
they get used to the system, they feel safer under those
conditions."
