NEW YORK, NY February 27, 2003 — The fire department's Hazardous Materials unit was created over 20 years ago to handle industrial accidents with toxic chemicals. But ever since the first World Trade Center attack ten years ago, the department has also had to focus on terrorism. Today's potential threats include a chemical, biological or radiological attack. As WNYC's Beth Fertig reports, firefighters are questioning whether they're able to meet these growing demands.
