World Trade Center 9/11 Response

The Sept. 11, 2001, terrorist attack on New York City's World Trade Center (WTC) resulted in intense fires, and the subsequent collapse of the structures released tons of dust on lower Manhattan. The NIEHS Worker Training Program (WTP) responded immediately, delivering 3,000 respirators to the site and providing expert support to coordinate occupational health issues during the recovery and cleanup processes. NIEHS-supported researchers were also on-site, collecting environmental and air samples shortly after the disaster. NIEHS responded by providing funds to support these efforts. Early in 2002, Congress appropriated $10.5 million to NIEHS for worker training and research support. The WTP awarded $6 million in WTC supplemental grants to WTP awardees to train new and existing New York City Fire Department hazardous material teams, environmental remediation workers, and site cleanup workers.
