What About Construction Equipment?
Treat equipment and vehicles with caution.

Around equipment, vehicles
  • Stay out of "blind spots"
  • Communicate with operators by radio signals and/or eye contact
  • Don't approach until you communicate with operator and he/she acknowledges you
  • Stay outside a "safety circle" around equipment
  • Stay clear of vehicles, know traffic control plan
  • Use spotters when you must work with your back to equipment or traffic

How Can We Be Safe When Placing TCDs?
Simple precautions make placement of TCDs (Traffic Control Devices) safer.

Workers should
  • Wear a Class III vest to be easily seen
  • Place, relocate, or remove TCDs when traffic flow is light
  • When possible, work from platform on vehicle
  • Use seat, seatbelt, fall restraint, or guardrail and a handhold when guardrail must be removed
  • Stay in constant communication with driver
  • Use shadow vehicle to warn drivers
