Working Adjacent to Live Traffic Job Safety Analysis (JSA)

Job / Task

Construction, maintenance, inspection, repair, installation, utility, surveying, and related work performed adjacent to active roadways, drive aisles, parking areas, or other locations where employees are exposed to moving public or site traffic.

Purpose

This Job Safety Analysis (JSA), also known as a Job Hazard Analysis (JHA), identifies hazards associated with working adjacent to live traffic and establishes safe work practices and controls to prevent struck-by incidents, vehicle intrusions, collisions, equipment conflicts, and other injuries to employees and the public.

Personnel Qualifications

Employees shall be trained for their assigned work and shall understand the traffic hazards and protective measures applicable to the work area.

Employees shall:

• Understand the work scope, traffic-control plan, work-zone boundaries, access routes, and emergency procedures.
• Recognize hazards associated with vehicle speed, traffic volume, limited sight distance, intersections, driveways, pedestrians, bicycles, and mobile equipment.
• Wear required high-visibility safety apparel when exposed to vehicular traffic.
• Perform flagging or specialized traffic-control duties only when trained and authorized.
• Maintain awareness of approaching traffic and know the location of a safe escape route.
• Use designated work-zone access and egress points.
• Keep tools, materials, and equipment within the protected work area whenever practical.
• Stop work and notify supervision when traffic-control measures are ineffective or conditions cannot be safely controlled.

Required PPE

PPE shall be selected based on traffic exposure, work activity, environmental conditions, and site hazards and may include:

• High-visibility safety apparel appropriate for the traffic and work conditions.
• Hard hat where head, overhead, or construction hazards exist.
• Safety glasses with side protection.
• Safety footwear with appropriate toe protection and slip-resistant soles.
• Work gloves appropriate for the task.
• Hearing protection where occupational noise exposure requires it.
• Weather-appropriate protective clothing.
• Additional task-specific PPE required by the work activity or site.

PPE does not replace effective traffic control, physical separation, positive protection, safe work positioning, protective vehicles, or other required engineering and administrative controls.

JSA – Job Steps, Hazards, and Controls

Step 1 – Plan the Work Adjacent to Traffic

Potential Hazards

• Vehicle intrusion into the work area.
• High-speed or high-volume traffic.
• Poor sight distance.
• Pedestrian or bicycle conflicts.
• Inadequate separation from traffic.

Required Controls

• Review the work scope and approved traffic-control plan before work begins.
• Evaluate roadway speed, traffic volume, lane configuration, intersections, curves, hills, driveways, and surrounding activities.
• Determine required signs, channelizing devices, barriers, protective vehicles, flaggers, or other controls.
• Plan work to maximize separation between employees and live traffic.
• Schedule work during lower-traffic periods when practical and permitted.

Step 2 – Inspect the Work Area

Potential Hazards

• Live traffic exposure.
• Uneven shoulders or surfaces.
• Limited escape routes.
• Overhead or roadside hazards.
• Poor visibility.

Required Controls

• Inspect the work area from a safe location before setup.
• Identify safe staging, parking, access, egress, and escape areas.

• Identify locations where workers could be trapped between traffic and fixed objects.
• Correct or control identified hazards before work begins.

Step 3 – Establish Traffic-Control Devices

Potential Hazards

• Workers struck while placing devices.
• Incorrect device placement.
• Vehicle intrusion.

Step 8 – Operate Vehicles and Mobile Equipment

Potential Hazards

• Collision with public traffic.
• Backing incidents.
• Workers struck by equipment.
