The illustrations and descriptive captions found on the 
following pages provide precautions to help eliminate 
injuries or fatalities.  Familiarize yourself with them when 
designing the total system. 

 

▲ 

1.   Familiarize  yourself with the precautions and 

warnings for the installer. Users are relying on your 
design to provide a safe installation. 

 

▲ 

2.  The operator is supplied with a primary obstruction 

sensing entrapment protection system.  The 
installation must also have a secondary entrapment 
protection system installed, such as photoelectric 
sensors or an electric edge system. 

 

▲ 

3.  When designing a system that will be entered from a 

highway or main thoroughfare be sure the system is 
placed far enough away from the road to eliminate 
traffic backup.  Distance from the road, size of the 
gate, usage levels, and gate cycle/speed must be 
considered to eliminate potential traffic hazards. 

 

▲ 

4.  Design the gate system so a person cannot reach 

over, under, around or through the gate to operate 
any controls.  Never place controls on the gate 
operator itself.
