10.1 World Trade Center Terror Attacks of 200110. Emergency Response and Disaster Preparedness | 10.2 Protect Building Air from Chemical Biological or Radiological Attacks
The terrorist attacks of September 11, 2001 exposed rescue and recovery workers in New York City to high levels of risk for job-related injury and illness. Workers included firefighters, police, emergency medical staff, demolition workers and drivers hauling away rubble, sniffer-dog handlers, and volunteer workers. Thousands of people, both workers and the public, were exposed to a huge dust cloud when the World Trade Center towers collapsed. In subsequent weeks, large dust exposures also occurred among those disturbing settled dust created by the disaster. Reports of adverse health effects from these exposures have been growing steadily over the years since, and reports of respiratory tract-related deaths due to dust exposure are growing.
NIOSH responded swiftly and addressed workers' immediate protection needs in the aftermath of the attacks. RDRP was an important part of this response, given the prominence of respiratory hazards caused by the WTC collapse. Approximately 30 RDRP staff members were deployed to the site, many of them experts in respiratory toxins or respirator use. NIOSH and RDRP performed the following activities:
In March, 2004, FDNY, Mt. Sinai and a group of other institutions (the Long Island Occupational and Environmental Health Center, the Mt. Sinai School of Medicine, the New York University School of Medicine, the City University of New York’s Queens College, and the University of Medicine and Dentistry of New Jersey’s Robert Wood Johnson Medical School) were awarded eight grants totaling $81 million to support an additional five years of medical monitoring. Funding was also provided to create a WTC Responder Health Consortium to promote coordination and data sharing between programs. The medical monitoring programs based at FDNY and Mount Sinai have played an extremely important role both in providing both service to sick workers and in doing research to better understand their health problems, including frequent and difficult respiratory problems.
Outputs and Transfer
RDRP was part of the NIOSH effort to distribute information to on-site workers and supervisors concerning respiratory hazards and exposure prevention through two documents:
In addition, RDRP assisted with the preparation of a topic page on the disaster and other electronic resources for emergency workers on the NIOSH Web page: http://www.cdc.gov/niosh/topics/wtc/ (A10-4).
In 2004, NIOSH sponsored a report by RAND's Science and Technology Policy Institute on emergency responders’ personal protective equipment needs, “Protecting Emergency Responders Volume 2: Community Views of Health and Safety Risks and Personal Protection Needs” (A10-5). The report helps define technology needs and research priorities for personal protection for emergency responders, including respiratory protection. It presents what members of the emergency response community believe to be the most important hazards that they face and their personal protection needs for those situations. The findings presented were derived from feedback obtained from 190 representatives from 83 organizations in the emergency response community nationwide. Volume 1 in this series was “Lessons Learned from Terrorist Attacks” and Volumes 3 and 4 concerned safety management and structural collapse respectively.
Through June 2005, the FDNY WTC Medical Monitoring Program had provided screening examinations to 15,284 firefighters and emergency medical service technicians. The WTC Medical Monitoring Program had provided screening examinations to 14,110 people. These programs have documented high rates of respiratory conditions including sinusitis, asthma, and a new syndrome termed “World Trade Center Cough.” These programs have published numerous peer-reviewed publications documenting the extent and severity of these problems.184
RDRP has provided consultation and help to both the FNDY WTC Medical Monitoring Program and the WTC Medical Monitoring Program in assessing longitudinal spirometry collected by the programs. Representatives of both programs participated in the RDRP-organized a workshop on “Interpretation of Longitudinal Spirometry Data in an Individual” previously described in chapter 4.2c.
An RDRP investigator with expertise in management of lung function data has worked with the Mt. Sinai group since the early stages of the medical monitoring program and was co-author of a recent publication describing high rates of respiratory symptoms and abnormal lung function in exposed workers.
Early after the disaster, NIOSH/RDRP personnel played an important role in helping New York City and other responding organizations implement procedures for occupational safety and health. Key areas were promoting use of respirators; and helping others, including OSHA, to do exposure assessment.
An internet search using Google showed that the Fact Sheets, “Workers in Secondary Response and Other Supporting Roles: Frequently Asked Questions About Exposure to Dusts and Gases” (A10-2) and “Protecting Workers at the World Trade Center Site and Response from NIOSH” (A10-3) have been cited by OSHA and a variety of other state and private organizations (A6-72).
NIOSH/RDRP extramural funding has played a major role in enabling a range of groups, including FDNY, Mount Sinai School of Medicine, and many others to provide medical screening to tens of thousands of people. Documentation that so many were sick from respiratory conditions has, in turn, motivated DHHS to commit $55 million to provide treatment services (see below).
CDC/RDRP will continue to fund the FDNY WTC Medical Monitoring Program and the WTC Medical Monitoring Program to provide medical monitoring services to the 40,000 responders exposed to the WTC collapse. This will allow continued follow up and detection of long term health effects.
CDC/RDRP will soon be funding a $55 million World Trade Center Treatment Program to provide medical treatment to those responders who suffer from diseases related to the WTC Collapse.
RDRP will continue to provide help and consultation to both the FDNY WTC Medical Monitoring Program and the World Trade Center Medical Monitoring Program in evaluating longitudinal lung function data of participants. RDRP will also remain engaged with these programs to help as needed with the long term problems of people exposed to the WTC Collapse.
