Just a couple of days ago at Pacific Northwest National Laboratory in Washington, a worker backed into a cart that had a large, heavy cylinder loaded on it. He soon figured out the cylinder was not secured properly as it tipped over slightly hitting the workers back. Luckily he walked away unharmed, but large, heavy objects should be secured well to avoid any major injuries. Another lesson learned is to always check your surrounding well before you begin working.
