ATSSA-Certified Flagging for Every Job Site
Power Safety Service LLC provides professional, ATSSA-certified flagging personnel for construction zones, utility projects, road work, and special events throughout Northern California. Our flaggers are trained, certified, and equipped to manage traffic safely in any work zone configuration – from simple one-lane closures to complex multi-phase highway projects.
Every flagger on our team carries current ATSSA certification and understands MUTCD standards and Caltrans specifications. We deploy to over 100 cities across Northern California, and we are available 24 hours a day, 365 days a year.
Why Certified Flagging Matters
Work zone safety is not optional. According to Caltrans, thousands of work zone incidents occur on California roads each year. Professional flagging is your first line of defense against accidents, injuries, and project shutdowns.
Untrained or uncertified flaggers create liability exposure for contractors, general contractors, and project owners. Our ATSSA-certified personnel eliminate that risk. They understand signal timing, gap analysis, and emergency procedures – the skills that keep your crew and the traveling public safe.
Flagging Services We Provide
Construction Zone Flagging
Our most common deployment. Whether you are running a utility dig, building pad, road overlay, or structural project, our flaggers integrate with your crew and manage traffic flow from the first cone to the last barrel pickup. We provide single-flagger and multi-flagger configurations depending on traffic volume and lane geometry.
Utility Work Flagging
Gas, electric, water, sewer, and telecom projects often require rapid deployment. Our flaggers are experienced with utility work zone setups and understand the unique challenges of working around live infrastructure. We coordinate with PG&E, SMUD, and municipal utility crews regularly.
Road Work and Highway Flagging
Lane closures, shoulder work, median work, and full road closures all require different flagging strategies. Our team is experienced with both state highway and local road configurations. We carry the right equipment for each scenario – paddles, flags, radio communication gear, and high-visibility PPE.
Special Event Flagging
Marathons, parades, festivals, and community events need traffic management that balances public safety with event flow. Our flaggers work with event coordinators and local law enforcement to keep participants and spectators safe while maintaining surrounding traffic circulation.
