Chlorine dioxide was first used in the United States as a drinking water disinfectant in the mid 1940's. It is used around the world, but particularly in North America and Europe where chlorine dioxide experiences ever-increasing use as a substitute for chlorine because it does not form carcinogenic trihalomethanes upon reaction with organic substances. Over four million pounds of chlorine dioxide are produced and used each day in North America.
Sabre has been involved in the restoration of nearly every major facility contaminated during the October 2001 anthrax attacks. Following completion of the Capitol Hill response, Sabre turned its focus to assisting the United States Postal Service (USPS) with its efforts to rehabilitate two major Processing and Distribution Centers (P&DC) that had been widely contaminated by the same anthrax-laced letters found at Capitol Hill. Specifically, these facilities were the USPS Curseen-Morris P&DC in Washington, DC and the USPS Trenton P&DC in Hamilton Township, New Jersey. These two facilities were approximately 14 million ft3 and 6 million ft3 in size, respectively. Sabre successfully eliminated all traces of anthrax contamination from each of these enormous facilities by "upsizing" the same base chlorine dioxide generation and application technology it developed during the Capitol Hill response.
In addition to the Hart Senate Office Building and USPS P&DC facilities, Sabre also successfully fumigated the former American Media Incorporated (AMI) building in Boca Raton, Florida where the first of the anthrax attacks occurred. Having perfected its chlorine dioxide treatment technology during the Capitol Hill and USPS responses, Sabre eliminated all traces of contamination from the AMI facility in record time and at reasonable cost.
Another use of the Company's chlorine dioxide treatment technology in the bio-terrorism response area was the treatment of several large cargo containers filled with lemons in October of 2004. The United States Coast Guard (USCG) had received a tip that several containers on a ship arriving from South America might be contaminated with a biological weapon. In responding to this alert, the USCG contacted Sabre and requested that each suspect container be fumigated with chlorine dioxide gas. Sabre promptly performed the requested treatment
