Traffic Control Within a Worksite

Make sure you follow these key engineering controls and work practices:

  • Develop and use a site plan that provides traffic flow details.
  • Limit access, barricade, or set up controlled access zones where the equipment will be used. For equipment that rotates and/or carries/dumps loads, create an access zone that extends beyond the maximum rotation/swing radius of the equipment and/or beyond the area where loads will be carried/dumped.
  • Illuminate the work area and its approaches to provide better visibility for drivers to safely travel through the work zone.

  • Establish/follow traffic control patterns (e.g., cones, barrels, barricades) in work areas.
  • Use spotters where visibility is limited.
  • Do not drive in reverse gear with an obstructed rear view unless the vehicle has an audible alarm or a signaler is used.
  • Ensure that spotters and heavy equipment operators have communications equipment or agree on and use hand signals.
  • Workers and pedestrians should make eye contact with heavy equipment operators before proceeding near equipment or operating areas.
  • Use ANSI/ISEA 107-2004 compliant high visibility safety apparel and headwear.
  • Provide signaling, slow/stop signs, or wands/flashlights for flaggers providing traffic control outside the work zone.
