President Donald Trump on Monday signed legislation to set up a national registry for firefighters to help track links between exposure to fumes and cancer. The Firefighter Cancer Registry Act requires the Centers for Disease Control and Prevention to set up a database in order to study possible links between cancer and the fumes and toxins firefighters are exposed to. The idea is use the information to develop better equipment and other techniques to protect firefighters from cancer-causing chemicals. "The brave men and women of the fire services who put their lives on the line for us each day deserve every ounce of support," said Rep. Bill Pascrell Jr., D-9th Dist., who sponsored the bill in the House. "Passing this bipartisan bill into law is Congress's way of having their backs."
