gate operators provide convenience and security to users.
However, because these machines can produce high levels of
force, it is important that all gate operator system designers,
installers and end users be aware of the potential hazards
associated with improperly designed, installed or maintained
systems. Keep in mind that the gate operator is one component
of a total gate operating system. Each component must work
in unison with the others to provide the end user with convenience,
security, and safety.

- A separate
pedestrian gate is always recommended. If the vehicular
gate is near a residential area or pedestrian traffic is
expected near the gate, electric gate edge, photoelectric
sensors or similar equipment should be installed to prevent
entrapment (see below)
designing a system that will be entered from a highway or
main thoroughfare, make sure the system is placed far enough
away from the road to eliminated traffic backup. To eliminate
potential traffic hazards, you must take into account distance
from the road, gate size, levels of use and gate cycle/speed.
The majority of injuries from gate operator systems occur
with Open Rollers or Ornamental "Grill Type" Gates.
The illustration and descriptive captions below see

injuries or fatalities. Familiarize yourself with them when
designing the total system.

operate any controls. Control stations must be seven feet
or more away from the moving gate and operator.
to see that the operator being installed is proper for the
gate's type, size and frequency of use.
- A freely
moving gate will require less force to operate and will
enhance the performance of the operator as well as the safety
devices used with the system. Therefore, you must ensure
that the gate has been properly installed and works freely
in both directions before installation, repair or service
any worn or damaged gate hardware.

injury or death can result from entrapment by the gate.
Therefore, if the vehicular gate is near a residential area
or pedestrian traffic is expected near the gate, such additional
safety equipment as electric gate edges or photoelectric
sensors must be installed to prevent entrapment.

will be installed on both sides of the gate. An electric

must install a push button control or a key switch to allow
for manual operation of the gate if the automatic gate entry
controls do not work. When installing a push button control,
locate it in a secured area within sight of the gate. Both
push buttons and key switches must be located seven feet
or more from the gate, gate operator and fence to ensure
that the user is out of the reach of a moving gate.

less than seven feet away from the gate so the gate or the
gate operator mechanism cannot be reached or touched. Any
puch button located in a building should be installed within
sight of the gate. Do not operate any control device without
monitoring the gate's movement.
not over tighten the clutch to compensate for a damaged

Traffic or Residential Area:
Internal operator load sensors and friction clutches
might not be sensitive enough to prevent arm or hand injuries.
For this reason, padded electric gate edges, or photoelectric
sensing systems are recommended when automatic gate openers
are used near pedestrian traffic. A suggested system is shown
above. Use of a separate pedestrian walk gate is always recommended.
"Grill Type" Gates
occur when people put their arms through openings in the grills
and the gate is operated. The person cannot retract his/her
arm and it get caught between the grill and the fence post or
fence. This potential hazard can be averted simply by placing
a mesh on the gate and the fence in the area of the gate. This
will help to prevent access through openings when the gate travels.
