Overhead permanent highway signs

Safety regulations for overhead permanent highway signs installation and maintenance include traffic control plans with signs, cones, barrels, and barriers to ensure drivers, workers, and pedestrians can clearly understand and follow the proper routes. Approved traffic control devices are used inside work zones. [5]

When highways must be closed for avalanche control, a Stop sign and a Road Closed sign should be clearly displayed on the gate, along with Type B red flashing lights. An Avalanche Control sign and a Prepare to Stop sign should have flags during the daytime, and a Stop Ahead sign should be positioned in advance of the closed gates. [4]

Flaggers should never enter the roadway before traffic has been stopped and should never turn their backs towards oncoming traffic. Operators of motor vehicles should always adhere to roadway warning signage by slowing down and paying close attention while in a work zone area. [3]

Employers should ensure that employees wear high-visibility clothing while performing operations on roadways. Roadway construction work should ideally be scheduled during non-peak traffic periods. [7]

Flagger stations should be illuminated at night, except in emergencies. [6]

It is essential to use temporary traffic control devices, such as signage, warning devices, paddles, and concrete barriers, consistently throughout the work zone and to set up temporary traffic control within a reasonable time prior to construction. [2]

When working with ladders, always read and follow the manufacturer's instructions, look for overhead power lines, maintain a 3-point contact, stay near the middle of the ladder, use a barricade to keep traffic away, and keep ladders free of slippery materials. Ensure ladders are placed on a stable and level surface. [1]

Never use ladders for purposes other than their intended design, use a stepladder with unlocked spreaders, use the top step or cap as a step, place a ladder on unstable bases, move a ladder with someone on it, use cross bracing for climbing, paint a ladder with opaque coatings, use a damaged ladder, leave tools on a ladder, use a stepladder horizontally, or use a metal stepladder near power lines.
