In addition to requesting the shutdown of airspace over New York City, the New York City Police Department (NYPD) calls for a second Level 4 mobilization, bringing its total deployment to nearly 2,000 officers.
The New York City Fire Department (FDNY) issues a fifth alarm for the South Tower, deploying several hundred additional firefighters to the disaster. Additional companies and off-duty personnel from across the metropolitan area travel to the scene.
When the planes crashed into the towers, 24,000 gallons of jet fuel ignited a fire that spread to 100,000 tons of organic debris and 230,000 gallons of transformer, heating, and diesel oils in the buildings, setting off a giant toxic plume of soot and dust from pulverized building materials, according to a Centers for Disease Control and Prevention report. The fires continued to burn during the rescue and recovery operations at Ground Zero, and workers were exposed to chemicals like asbestos, carbon monoxide, hydrogen sulfide, crystalline silica and other metals and particulates.
More than 7,000 FDNY Firefighters and EMTs have been treated for a 9/11 injury or illness now almost 14 years later.
5,400 members have been diagnosed with lower respiratory diseases such as asthma, chronic bronchitis, and less commonly emphysema, COPD, sarcoidosis or pulmonary fibrosis.
5,200 members have been diagnosed with upper respiratory diseases such as chronic rhinosinusitis and/or vocal cord diseases.
3,700 members have been diagnosed with mental health stress-related conditions.
5,400 members have been diagnosed with gastroesophageal reflux disorders.
1,100 have developed a cancer caused by 9/11 toxins. Of those, 44 have died despite access to treatment.
