811 Day

811 Day is an annual initiative led by the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) to ensure the practice of safe digging is echoed in communities by calling 8-1-1, a nationwide toll-free number, before any excavation project. 

As an agency committed to safety and protecting the nation’s 2.6 million miles of pipeline, PHMSA recognizes the importance of damage prevention and seeks to eliminate excavation damage, which remains the leading cause of pipeline incidents.

Calling 811 or visiting, has proven to be the foremost preventive measure in excavation safety and damage prevention. Research has revealed that if someone calls 8-1-1 before they dig, they have a 99 percent chance of avoiding an incident, injury, harm to the environment and even death. 

In addition to 811 Day, PHMSA has partnered with several organizations including the National Energy Foundation (NEF), and the Common Ground Alliance (CGA) to develop several community outreach efforts and public awarness campaigns including: the 811 video and poster contests for elementary, middle, and high school students as well as social media and digital campaigns for National Safe Digging and National Safety Months.

Further, the agency has awarded nearly $1.3. million in One-Call grant awards for state damage prevention and published Congressional publications including "A Study on Improving Damage Prevention Technology," which was released in 2017.
