Tornado Rips Developing

SEnuke: Ready for action

About 150 staff at Parsons Manufacturing Co. in Illinois had been shocked to see their company's constructing turned into a pile of mangled steel beams and other rubble as an F-4 tornado ripped by way of the region. But what's even far more shocking is that they were inside the developing when the storm hit.

Thanks to reinforced concrete masonry shelters, all 150 people walked away from the disaster with no a scratch. An F-four tornado has wind speeds from 207 to 260 mph.

Winds from the storm leveled the 225,000-square-foot plant and destroyed at least half a dozen homes nearby.

\We have been told over a public address program to head to the 3 restrooms, which are created of reinforced concrete masonry and serve as storm shelters. Dig up more on our related article by clicking read. When we got to the shelters, we could see steel beams and machinery flying in the air,\ recalled Dave McClallen, a Parsons employee.

Woodford County Emergency Services & Disaster Agency volunteer Dustin Oltman said reports indicated that the storm inflicted the most harm on the half-mile region in Roanoke, Ill., where Parsons Manufacturing Co. is located.

Bob Parsons, owner of Parsons Manufacturing, which makes components for the construction and mining industries, did not want to take any probabilities when constructing his operation immediately after a near miss of his 1st company by a tornado in 1972. When he built an expanded enterprise across the street, he included reinforced concrete masonry storm shelters inside. He stated that he never could have guessed that decision would save 150 lives 30 years later.

The inherent strength of reinforced concrete masonry tends to make it an exceptional decision to withstand wind-borne debris - the largest threat to occupants in these storms, stated Dennis Graber, an engineer on the employees of the National Concrete Masonry Association in Herndon, Va.

\Researchers at the Wind Science and Engineering Research Center at Texas Tech University demonstrated this truth at a wind projectile test in September 2003,\ Graber said. \In that test, solid grouted 8- and 6-inch reinforced concrete masonry wall panels withstood the standardized FEMA [Federal Emergency Management Agency] test of 15-pound, two by four projectiles shot at one hundred mph, which is representative of debris in a 250-mph tornado.\.
