¾ Preventing workers from being run over by construction trucks and equipment. The Project Goals

¾ Limit exposure of workers-on-foot to construction traffic.

¾ Focus on blind areas around construction and equipment.

‹ Develop exposure monitoring system(s)

‹ Evaluate injury prevention measures The Interventions

Blind Areas Definition of Blind Area

¾ A blind area is the area around a vehicle or piece of construction equipment that is not visible to the operators, either by direct line-of-sight or indirectly by use of internal and external . Vehicle Blind Spots

¾ Running over people

¾ Running over materials

¾ Striking other equipment and vehicles

¾ Rollovers

¾ Contact with utilities Area of fully obstructed view Non-Construction Vehicle Blind Spot Measurements

Methods ¾ International Organization for Standardization (ISO) 5006

¾ Manual methods

‹ Light Bar

‹ Operator

¾ Computer methods

‹ Design Drawings

‹ Laser Scans

Internal Traffic Control Plans Why Develop an Internal Traffic Control Plan?

¾ Coordinate vehicle/equipment movement inside the work zone

¾ Limit exposure of workers on foot to construction traffic

¾ Reduce hazards for equipment operators Definition of Internal Traffic Control Plans (ITCP)

“STRATEGIES TO CONTROL THE FLOW OF CONSTRUCTION WORKERS, VEHICLES AND EQUIPMENT INSIDE THE WORKZONE” Traffic Control Plans TCP – ITCP PARALLELS

TCP ITCP TYPICAL ⇒ MODEL

RESPONSIBLE ⇒ COMPETENT PERSON PERSON ⇒ REQUIRED BY CONCEPT MUTCD PRINCIPLES OF SAFE CONSTRUCTION TRAFFIC CONTROL

¾ Reducing the need to back up equipment ¾ Limiting access points to work zones ¾ Establishing pedestrian-free areas where possible ¾ Establishing work zone layouts commensurate with type of equipment PRINCIPLES OF SAFE CONSTRUCTION TRAFFIC CONTROL

¾ Providing signs within the work zone to give guidance to pedestrians, equipment and trucks

¾ Designing buffer spaces to protect pedestrians from errant vehicles or work zone equipment

¾ WORK AREA DIAGRAMS SAFETY POINTS

1. Truck spotter stays at paver

2. Stage trucks to minimize backing

3. No walking behind backing trucks, in front of paving NOTES PAGE machine, across hot mat, or over trailer tongue. SAFETY POINTS PERSONNEL Truck Drivers Truck Spotter PERSONNEL Paver Operator Roller Operators Inspector EQUIPMENT Superintendent Test Personnel

EQUIPMENT Oiler Trucks Dump Trucks Pavers Rollers Detailed Notes Safety Points

¾ No workers in traffic zone ¾ Spotter uses hands free radio to talk to trucks ¾ No workers on foot between a backing truck and the paver ¾ Truck spotter remains at paver until truck stops ¾ Inspectors remain away from paving train and notify spotter before obtaining samples

¾ Review TCP and other contract documents ¾ Determine site-specific ITCP needs ¾ Draw work space ¾ Add pedestrian and equipment paths ¾ Locate staging areas ¾ Prepare notes and plan Internal Traffic Control Plans – Questions ¾ Can the need for backing be reduced or eliminated? ¾ Can the number of vehicle access points into the work space be reduced? ¾ Can pedestrian-free zones be established? ¾ Can the work space accommodate the equipment being used? ¾ Do any physical features of the site place operators at risk?
