23/03/ · On August 21, , with funding from the U.S. Congress through FEMA, the National Institute of Standards and Technology (NIST) announced its building and fire safety investigation of the World Trade Center (WTC) disaster that occurred on September 11, WTC Disaster •September 11, –Terrorist attack •Buildings and infrastructure –disaster –Colossal damage and destruction •Building performance / investigation –Engineering profession •FEMA/ASCE – team of engineers –Building Performance Assessment Team (BPAT). The original World Trade Center was a large complex of seven buildings in the Financial District of Lower Manhattan, New York City, United States. It opened on April 4, , and was destroyed in during the September 11 attacks. On the World Trade Center site, three more office towers were to be built one block east of where the original towers stood. 4 WTC, meanwhile, opened in November , making it the second tower on the site to open behind 7 World Trade Center, as well as the first building on the Port Authority property.

High concentrations of coarse and supercoarse WTC Dust were inhaled and deposited in the conductive airways in the head and lungs, and subsequently swallowed, causing both physical and chemical irritation to the respiratory and gastroesophageal epithelia. The numerous health effects in these people were not those associated with the monitored PM 2.

Attention was never directed at the very high concentrations of the larger-sized and highly alkaline WTC Dust particles that, in retrospect, contained the more likely causal toxicants. Unfortunately, the initial focus of the air quality monitoring and guidance on exposure prevention programs on low-concentration components was never revised.

Public agencies need to be better prepared to provide reliable guidance to the public on more appropriate means of exposure assessment, risk assessment, and preventive measures. The lead author has been engaged in his semi-retirement in scientific recapitulation on environmental health topics of 1 his long-term interests; 2 substantial impacts in terms of public health and concern; and 3 continuing concern and confusion in 1 the scientific literature; 2 among the regulatory agencies; and 3 the public.

His two recent recapitulations, published in this journal, addressed 1 toxicological and epidemiological studies of effects of the cardiovascular effects of ambient air fine particulate matter PM; PM 2. This paper, providing a holistic reappraisal on the health impacts of inhalation exposures to dust created by the collapses of the World Trade Center WTC twin towers on September 11, , reappraises the work of many investigators, including the pioneering contributions of its co-authors, on the characterization, toxicology, and health effects of inhaled WTC Dusts.

While the lead author did not get personally involved until , he, like many other environmental health researchers, was surprised to see the emerging evidence in the literature that demonstrated substantial health impacts among populations exposed to WTC Dusts in Lower Manhattan.

Click here for audio of Episode Today’s story is about cigarettes and fertilizer. The University of Houston’s College of Engineering presents this series about the machines that make our civilization run, and the people whose ingenuity created them. O n April 19, , some murderers parked a U-Haul truck filled with only slightly modified ammonium nitrate fertilizer in front of an Oklahoma City office building.

They ignited it, killed people, and injured more. That was 48 years and two days after a far larger charge of the same material had gone off accidentally here in Texas. Hugh Stephens tells how, on April 16th, , two Liberty ships docked at Texas City on the Houston ship channel — the Grandcamp and the High Flyer. Both were loading cargoes of that same fertilizer.

The Grandcamp held tons — the High Flyer , tons. The rest of High Flyer ’s cargo was sulfur. At that morning, a small fire broke out in one of the Grandcamp ’s holds. The ship master tried to suffocate the fire by closing the hatches.

On September 11, , 19 militants associated with the Islamic extremist group al Qaeda hijacked four airplanes and carried out suicide attacks against targets in the United States. Two of the planes were flown into the twin towers of the World Trade Center in New York City, a third plane hit the Pentagon just outside Washington, D. WATCH: Minutes That Changed America on HISTORY Vault. On September 11, , at a. The impact left a gaping, burning hole near the 80th floor of the story skyscraper, instantly killing hundreds of people and trapping hundreds more in higher floors.

As the evacuation of the tower and its twin got underway, television cameras broadcasted live images of what initially appeared to be a freak accident. Then, 18 minutes after the first plane hit, a second Boeing —United Airlines Flight —appeared out of the sky, turned sharply toward the World Trade Center and sliced into the south tower near the 60th floor.

The collision caused a massive explosion that showered burning debris over surrounding buildings and onto the streets below. It immediately became clear that America was under attack. The hijackers were Islamic terrorists from Saudi Arabia and several other Arab nations. Some of the terrorists had lived in the United States for more than a year and had taken flying lessons at American commercial flight schools.

The 19 terrorists easily smuggled box-cutters and knives through security at three East Coast airports and boarded four early-morning flights bound for California , chosen because the planes were loaded with fuel for the long transcontinental journey. Soon after takeoff, the terrorists commandeered the four planes and took the controls, transforming ordinary passenger jets into guided missiles.

Surprisingly, the World Trade Center towers were actually engineered to withstand the impact of a airliner collision. The resultant explosion and extremely intense fire would have substantially decreased the tower’s ability to maintain it’s structural integrity. The collapse of the upper floors and the inability of the lower floors to bear the load resulted in the catastrophic failure of both towers.

As the largest, and one of the most eclectic, urban center in the United States, New York City felt the need to develop an Office of Emergency Management to coordinate communications and direct resources in the event of a mass disaster. Practice drills were then carried out to assess and improve disaster preparedness.

The day of 11 September began with the unimaginable. As events unfolded, previous plans based on drills were found not to address the unique issues faced and new plans rapidly evolved out of necessity. Heroic actions were commonplace. Much can be learned from the events of 11 September Natural and unnatural disasters will happen again, so it is critical that these lessons be learned. Proper preparation will undoubtedly save lives and resources.
