Safety and Risk Management Flashcards

What is the primary purpose of a buffer space in a temporary traffic control zone?

Answer: To protect workers and equipment by separating them from traffic

A buffer space is a protected area between the traffic lane and the work space, designed to shield workers and equipment from errant vehicles.

During flagging operations at night, which additional precaution is MOST important?

Answer: Ensure all PPE and devices are retroreflective and properly illuminated

Night operations require retroreflective and illuminated PPE and devices so flaggers and traffic control elements remain visible to drivers.

A driver becomes verbally aggressive toward a flagger. The correct response is to:

Answer: Calmly repeat instructions, avoid escalation, and report the incident to the supervisor

Flaggers should remain calm, avoid arguments, continue safe operations, and document aggressive behavior for their supervisor.

Which factor is MOST critical when determining the length of a one-lane, two-way traffic control zone?

Answer: The sight distance available and the speed of approaching traffic

Sight distance and approach speed determine how far in advance drivers need to be warned and how long a flagger-controlled section can safely be.

Under California law, what is the minimum age requirement to work as a certified flagger?

Answer: 18 years old

California requires flaggers to be at least 18 years old and hold a valid flagger certification.

What does a flagger do when transitioning from STOP to SLOW?

Answer: Lower the STOP paddle face-down and raise the SLOW side toward traffic

The flagger rotates the paddle so the SLOW face is displayed toward approaching traffic before directing vehicles to proceed.

Why is it important for a flagger to maintain eye contact with approaching drivers?

Answer: To confirm the driver has seen and acknowledged the flagger's signal

Eye contact helps the flagger verify that the driver is aware of the stop or slow signal and is responding appropriately.
