According to the Storefront Safety Council, more than 100 vehicles crash into buildings every single day in the United States. That … Read more

When I ran security at the finish line of our local triathlon two years ago, we learned fast that the line of athletes and spectators waiting to enter a venue moves only as fast as the screening process. By the end of that race weekend, our team had screened more than 4,800 people across two … Read more

Moving heavy freight by hand is the fastest way to burn out your crew and rack up injury claims.
