  • Triad Engineering Promotes National Construction Safety Week: The Power of Safe Choices

    By: Vanessa Ervin

    Construction Safety Week is May 7-11, 2018 and Triad is joining the national effort to promote the ‘Power of Safe Choices.’ Multiple tips were discussed each day to empower all employees in the decisions they make each day. The #ToolboxTalks encouraged recognizing team members, leading by example, engaging and empowering, and developing team members. Everyone on a job site should work together to address and solve any safety issues. Everyone on the job has input from past experiences, so it is important to allow communication from all sides. Always be a leader on the jobsite when it comes to safety, and make it the top priority no matter the circumstances! #safetyweek2018
