Barricade, Flagging & Hazard Sign Safety Part 3

Personnel using flagging:

• Flag-off only the areas where the hazard exists. Flagging-off too large an area interferes with other work.
• Remove the flagging when the work is complete and recover for further use.
• Use the appropriate type of flagging for the hazard. Check with the supervisor and attain permission for the installation of red “Danger Do Not Enter” flagging.

Identify all projected objects or guy wires with high visibility markings/flagging. All flagging must be tagged identifying the supervisor’s name, contact number, date and reason for its use.

Warning signs shall be used on the Pipeworx project to indicate specific hazards. Some examples of warning signs on the project are:

Danger, High Voltage, Authorized Personnel Only, Caution, Overhead Work, Danger, Swing Area,

Flashing lights are also used to bring attention to hazards during periods of darkness or poor
visibility. Flashing lights shall be used:

At excavation or trenches, which are within 3 m of any vehicle or equipment movement. For slow
moving, wide or long loads, to identify temporary obstructions in roadways, crosswalks, caution,
overhead work.
