If an operator or pedestrian steps out of line and has a run-in with a lift truck, the
lift truck will most likely win. Here's how to cut your chances of confrontation.
"A pedestrian being struck by a lift truck is the most common lift truck
accident," says Diane Cashen, claims manager at clark Material Handling Company.
"Injuries from lift truck run-ins can range from a minor bump to severe crushing and
even death. Based on accident investigations, the nearly universal cause of these
accidents has been operator and/or pedestrian inattentiveness. No matter how many bells,
whistles, mirrors and horns you put on a lift truck, nothing can take the place of
properly trained operators and pedestrians aware of lift truck traffic in a plant,"
she says.
"The first step in preventing lift truck/pedestrian run-ins is to analyze plant
work flows and separate people on lift trucks from people on foot as much as
possible," Cashen says. "Only the people who work in the plant can identify the
best ways to reduce the chances of pedestrian accidents. If you have operators performing
a task with a fellow worker close to the machine or its moving parts, something is
wrong." Reevaluate the task and find a way to complete the job with less chance of
lift truck/pedestrian interaction.
When specifying a lift truck, you can add lights, alarms and mirrors to meet any
special needs in your plant. "We offer these devices so our lift truck buyers can
customize their trucks according to their needs, and we encourage our customers to
consider using these devices if they feel it will reduce the chance of accidents at their
facilities. Also, operators should help with the selection process, because some workers
find warning devices annoying and disconnect them," she says.
These devices cannot replace constant vigilance. Operators can't assume that
pedestrians are aware of the moving lift truck just because the back up alarm is beeping
or the strobe light is flashing. The best bet is to mark specific walking areas for
pedestrians where lift trucks aren't allowed. However, pedestrians often must walk across
lift truck operating paths, so the chances of accidents are still there.
When loads restrict forward vision, operators must take special precautions to prevent
pedestrian or plant equipment collisions. Often, reverse travel is the safest when forward
travel view is restricted by load. When traveling in reverse, operators must be especially
careful to look in the direction of travel. Spotters are essential when visibility is
hindered, Cashen points out.
Training, training, training
After examining lift truck travel and plant layout,
training is the next item that must be implemented to minimize lift truck run-ins. Lift
truck operators and plant workers should be trained and often reminded about material
handling and lift truck travel in the plant.
Your training should reinforce to operators these simple rules:
Watch where you're going. Always face the direction of travel, and when coming to
intersections and blind spots, sound your horn to help alert pedestrians of your
whereabouts.
Ask them to stand back. Always be on the look-out for pedestrians. Make eye contact with
them so you know they are aware of your presence. Double-check behind you for pedestrians.
They may not understand that a lift truck steers from the back, and its tail swing could
put them in danger.
3. If you don't have a clear view of travel, don't move the truck. Get help from a
spotter. If your forward view is restricted, travel in reverse.
Be especially careful in dock areas. Here, congestion and high pedestrian traffic
combined with tight working areas create hazardous conditions. Before you start, make sure
truck drivers and other pedestrians are out of the way.
Keep pedestrians away from your forks, especially when lifting loads. Sudden load shifts
could drop material on them, causing injury.
No hitchhiking. Don't allow passengers to ride on any part of the lift truck. They block
view, distract you and do not have a safe area on which to ride.
If the load must be held in place by another person for transport, stop. The lift truck
you are using is not equipped to handle this type of load and places the person holding
the load in grave danger. Use the right equipment to move loads.
Read the operator's manual before you operate any lift truck. It's the best way to
understand the critical operating nuances of a lift truck model.
Pedestrian training
Training operators is only half the equation. Because pedestrians are vulnerable, it's
important they understand the dangers when walking around a facility. The two most
important concepts for newcomers to the plant to understand is that lift trucks can't stop
on a dime and that when they turn, they pivot at the rear instead of the front.
Lift trucks are designed to stop slowly to minimize load damage from sudden changes in
load balance. Sudden stops can also adversely affect the operator's position and the
truck's stability. That means pedestrians must give lift trucks a wide berth just in case
the operator doesn't see them and they must stop quickly to avoid a run-in.
Lift trucks are rear-steering vehicles, which gives them the best maneuverability
possible. That means it steers completely differently from a front-steer vehicle which can
fool pedestrians. The tail swing can pin or crush pedestrians if they get too close.
Additional equipment to consider:
Because material handling operations vary greatly from plant to plant, it's imperative to
analyze the operation to determine what types of additional equipment may be needed to
improve material handling safety.
Some items to consider:
Flashing, revolving or strobe lights: Available in many colors, so you can select a
unique color for use on all mobile equipment. Don't use that color for any other signal,
such as in production areas or fire exits.
Mirrors: Mirrors can give the operator an improved view of the area surrounding the lift
truck when normal operating vision is otherwise obstructed. Because of distortion, don't
rely on these mirrors to maneuver around the facility, for the same reason it says in your
car's side-view mirrors, "Objects in mirror are closer than they appear." Always
keep a clear view of travel.
Headlights: Helpful when operating in trailers or other dimly lit areas, they can be
mounted on the front or rear of the lift truck.
Paint: The standard Clark color of high-visibility green with low-glare matte black
uprights and overhead guards can be changed to safety yellow or bright orange when you
specify your truck.
Audible alarms: These beeping devices are activated whenever the lift truck operates in
reverse or whenever it is moving. Consider variable-decibel alarms, which adjust volume
based on ambient noise level. When you are specifying your lift truck, work with experts
at your clark dealer to identify and select any additional
equipment options that may help operators and pedestrians steer clear of each other in the
plant.
