Beirut Tragedy Underscores Importance of Security Window film Installation

 The second of two explosions that rocked Beirut, Lebanon on Aug. 4, 2020, caused more than 170 deaths to date and injured more than 6,000. Property damage has been estimated at $10-$15 billion and more than 300,000 people are homeless.

Some of the deaths and unspecified thousands of the injured were victims of glass shards, as the force of the explosions shattered windows sending glass flying through the air in a large section of the city.

What triggered the main explosion has not yet been determined. But it has been confirmed that 2,750 tons of ammonium nitrate stored at the Beirut port for six years without proper safety measures was detonated. The blast is considered one of the most powerful non-nuclear explosions in history.

Coincidently, the same material – ammonium nitrate – was used in the 1995 terrorist attack on the Alfred P. Murrah Federal Building in Oklahoma City, Okla. That bombing caused 168 deaths and nearly 400 injuries. As in the Beirut blast, flying glass over a multi-block area was a significant culprit in the casualty total.

Following the Oklahoma City bombing, window film manufacturers who had been making solar control window film for years turned their efforts to producing a film that would hold glass windows in place during explosions and other unforeseen catastrophic events.

The result was creation of security window film, also known as fragment retention window film and shatter resistant window films. These films quickly became popular with architects and engineers in the federal government and owners of large office buildings. Among the first high-profile buildings to have security window film installed were FBI headquarters in Washington, D.C. and the Pentagon.

A few years later, on Sept. 11, 2001, one of the four planes involved in the terrorist attacks, American Airlines Flight 77, crashed into the Pentagon. Loss of life and injuries were substantial in the location of the crash, but further casualties were prevented, according to government officials, in the peripheral areas of the building as the windows that had security window film installed held in place.

Since then, thousands of buildings around the country have had security window film installed to protect employees from unexpected terrorist attacks, unwanted intruders and catastrophic foul weather events. Among them are all the U.S. House of Representative and Library of Congress buildings, the U.S. Capitol, Departments of Energy, Transportation and EPA headquarters, Grand Central Terminal, O’Hare International Airport and Seattle-Tacoma International Airport, the United Nations, Philadelphia and Denver mints and the Willis [former Sears] Tower.
