SECTION 3: Barricades & Signs

The use of barricades and signs is an important part of any job. Barricades should act as physical barriers, preventing contact by passers-by with the hazards created by construction or maintenance activities, while signs should be used to direct traffic, both vehicular and pedestrian, safely through or around the work site. While barricades and signs should be used wherever necessary for the physical protection of people or property, the following is a list of activities where their use is required by code or regulation:

1. Wherever construction debris is dropped without the use of an enclosed chute.

2. Areas with temporary wiring operating at more than 600 volts.

3. Work areas for electrical equipment with exposed, energized parts.

4. The swing radius of the rotating superstructure of cranes or other equipment.

5. Wherever equipment is left unattended near a roadway at night.

6. Excavations.

7. Areas used for the preparation of explosive charges or blasting operations.

8. Street openings, such as manholes.

9. Construction areas in energized electrical substations.
