Safety FAQ's
Here are just a few of the safety questions we get from customers and the general public, as it relates to traffic signal maintenance and transportation infrastructure.
Q: How does GreenArrow protect crews working in active traffic lanes?
A: Working near moving vehicles is our primary hazard. We strictly adhere to the Manual on Uniform Traffic Control Devices (MUTCD) standards for every work zone. This includes setting up advanced warning signs to alert drivers, using proper tapering with cones to guide traffic away from workers, and establishing a "buffer space" between the traffic and the work area to provide a physical margin of safety.
Q: What protocols are in place for working with high-voltage signal equipment?
A: Traffic signals often operate on high-voltage circuits that present significant electrical risks. Our technicians are trained in strict Lockout/Tagout (LOTO) procedures to de-energize circuits before maintenance begins. When testing live equipment is necessary, our crews utilize specialized Personal Protective Equipment (PPE), including arc-flash rated clothing and insulated tools, to prevent electrical shock.
Q: How do you ensure public safety while working on busy sidewalks or intersections?
A: Our safety commitment extends beyond our crew to the pedestrians and motorists around us. When working in public right-of-ways, we secure the perimeter with barriers to prevent pedestrians from accidentally entering the work zone. We also ensure that temporary pedestrian paths are clearly marked and accessible (ADA compliant) so that foot traffic can move safely around our equipment.
Q: What safety measures are used when working at heights in bucket trucks?
A: Falls are a major industry risk. All GreenArrow technicians working from aerial lifts (bucket trucks) are required to wear a full-body harness and a shock-absorbing lanyard attached to the boom at all times. We also perform daily equipment inspections to ensure the lift's hydraulics and stabilization outriggers are fully functional before the bucket ever leaves the ground.
