What precaution should be taken when operating near traffic?

Establishing flagger operations and deploying warning signs is crucial when operating near traffic to ensure the safety of all individuals involved, including emergency responders and motorists. This precaution helps to control the flow of traffic, alerting drivers to the presence of emergency operations and potential hazards. Proper flagger operations can help minimize the risk of accidents by directing vehicles safely away from the work area and ensuring that responders can operate without the interference of oncoming traffic. Warning signs further enhance visibility and communication to approaching drivers, indicating that they should reduce speed or change lanes.

While the other options may seem relevant in certain contexts, they do not provide the comprehensive safety measures that flagger operations and warning signs offer in managing traffic around emergency scenes.
