Maintenance Precautions
* Refer to OSHA regulations 1910.146. Confined Space and 1910.147. Lockout/Tagout
MAINTENANCE
Always post safety warnings and barricade the
work area at dock level and ground level to
prevent unauthorized use of the equipment before
maintenance is complete.
If it is necessary to service the barrier with the arm
in the vertical position, engage a safety chain to
prevent the arm from falling.
In addition, it is recommended and good safety
practice to use use an additional means to support
the raised barrier arm. This additional means may
include, but is not limited to a boom truck, fork truck,
stabilizing bar or equivalent.
A hard hat or other applicable head protection
should always be worn when working under or
around the barrier.
Always stand clear of the raised barrier arm when
working in front of the barrier.
