Two Federal Agencies Have Interest in Work Zone Safety MUTCD? The Manual on Uniform Traffic Control Devices (MUTCD) was developed to create standardized control during roadway construction, maintenance, and utility (work zone) operations. Adopted by OSHA on 9/12/2006 Work Zone What is a work zone?

When Are Flaggers Necessary? Flagger Safety Construction Vehicles & Equipment in Uncontrolled Traffic Lanes Two way Traffic Can Pass in Only One Direction Pathway Through the Construction Is Too Confusing for Motorists Mobile Work Zone Stand in the Proper Location Remain Attentive Always Face Traffic Communicate Effectively Clothing and Equipment Meet Standards Proper Training Flagger Hazards Paddle Placed in Cone; Flagger in Shadow Confusing Signal Flagger Not Facing Oncoming Traffic Concrete Jersey Drums: Filled with sand and used at ends of guardrails: 8
Drums (filed with sand) Guardrails: Used to divide traffic Used to protect pedestrians Guardrails Guardrails Guardrails Guardrails shall be constructed of 2 X 4 or equal materials.
