Haag's January Newsletter- 95th Anniversary + Imperial Sugar Explosion

95 Years of Failure & Damage Analysis
As we celebrate Haag’s 95th anniversary in 2019, we thought it would be fun to take a look back at a few of the many noteworthy projects completed by Haag staff. During each month in 2019, this blog will feature noteworthy projects, as selected by our senior staff. We are fortunate to have several employees still with Haag who started in the 1970s, and one—my predecessor as Haag’s president & CEO, John Stewart (featured below)—who will be celebrating 50 years with Haag!
Around 7:00 am on February 7, 2008, a massive explosion occurred in the center of the Savannah Foods/Imperial Sugar facility, destroying or extensively damaging all three sugar silos and the packaging buildings that surrounded the silos. Sugar dust was believed to have been ignited by operating machinery. Many buildings outside the center of the plant also was extensively damaged. Investigations by government agencies as well as private experts concluded that the event was caused by an explosion of sugar dust followed by a fire wherein the sugar in the silos and throughout the area burned. Tragically, 14 individuals were killed in the blast and some 40 others were burned or injured.
Haag Research & Testing: Ice Ball Testing
Haag Research & Testing pioneered simulated hail impact testing of roofing materials. We have propelled simulated hailstones (ice balls) using various methods since 1963. Now, Haag’s patented ice ball launcher, the IBL-7, is our premier simulated hail testing tool. The IBL-7 was used by Factory Mutual to develop the ANSI FM 4473 ice ball impacting protocol, which is the industry standard in testing roofing materials for their hail resistance. Although the standard references impacts by 1-1/4, 1-1/2, 1-3/4, and 2 inch diameter ice balls, the IBL-7 can launch ice balls ranging from ½ inch to 2-1/4 inches in diameter at free-fall or wind-driven velocities. 
Haag has completed hundreds of ice ball tests and we’re accepting new projects now. For more information, please give us a call: 800-527-0168.
