Most drivers and commuters are likely to have seen a flagger on the job. These are the personnel who control vehicle-traffic to create a safe environment for construction/repair projects, such as those involving roadways or parking lots. Flaggers help notify drivers of the needs for reduced speeds or restricted lane flow; as such, they play key roles in creating and maintaining safe construction sites.
Flaggers must fully understand the use of all signaling devices at his/her disposal, including flags, portable signs, and paddles for daytime use. Flaggers are also used after dark, usually with lighted wands or other illuminated signaling devices. They may also coordinate with a supervisor and other flaggers in same construction area to ensure the workspace is safe.
Flaggers must also engage in constant communication with other flaggers, especially in situations involving lane closures and alternating one-way flow of traffic. Most flaggers are equipped with radios or walkie-talkies to communicate with each other and their on-site supervisor.
Although there are no formal education requirements for the position, applicants should have strong communication skills and be in good physical shape. Most flaggers must be able to stand for hours at a time and reasonably avoid drivers and other hazards on the job site. This is outdoor work, sometimes in hot or cold weather, and flaggers should expect to spend most of their work-days on their feet.
