Over the past two decades, The University of Texas Medical Branch (UTMB) has developed a strong program in infectious disease research. UTMB has an internationally recognized group of emerging infectious disease investigators at a time when this subject is of critical public health importance and interest.
In 1997, UTMB decided to construct a Biosafety Level 4 (BSL4) laboratory facility to safely handle and maintain infectious agents so that UTMB researchers could continue making important discoveries on how to combat some of the most deadly diseases known to man. This was well before the anthrax attack of 2001, and before the decision in 2003 by the National Institutes of Health (NIH) to partially fund construction of the Galveston National Laboratory on the UTMB campus. Construction of UTMB's BSL4 laboratory was largely funded by a grant from The Sealy & Smith Foundation of Galveston, a philanthropy solely dedicated to benefiting UTMB, with additional support for the facility from NIH, among other sources.
The BSL4 laboratory was formally dedicated on November 17, 2003, and was named the Robert E. Shope, MD, Laboratory in honor of Dr. Shope, a world-renown virologist who was a member of the UTMB faculty until his death from complications of idiopathic pulmonary fibrosis in early 2004. UTMB's Shope Lab, as it has come to be known, has been fully operational since 2004. It is the first full-sized facility of its kind in the nation to be located on a university campus.
BSL4 is the highest biosafety rating for laboratories dealing with highly contagious organisms. BSL4 laboratories are designed to prevent microbes from being released into the environment and to provide maximum safety for the researchers inside. BSL4 labs require some of the most sophisticated architectural, engineering and construction techniques to ensure the safety of both the scientists inside and the surrounding community. Construction of the Shope Lab entailed a three-story addition to the existing Keiller Building, as well as some renovation work within the existing building infrastructure to accommodate the addition. The combination of new work and renovation work resulted in an additional 12,000 gross square feet of space. Often likened to a submarine encased inside a giant bank vault, UTMB's Shope lab features 2,000 square feet of dedicated research space. The remaining 10,000 square feet of the facility contains support equipment designed to capture and destroy any microbes before they can exit the structure.
While a BSL4 may look like an ordinary building from the outside, the building itself is anything but ordinary. BSL4 design features demand that:
- All seams, joints and doors are sealed to make the building airtight. Windows cannot be opened, and air does not flow in or out under the doors.
- Air is pumped in and out of the building through a sophisticated filtration system to catch even the tiniest microscopic particles, including bacteria and viruses.
- All air ducts are welded stainless steel and rigorously tested to ensure they are airtight.
- The laboratories are surrounded by "buffer" corridors to help protect them in the event of an accident or attack.
- Airlocks, fumigation chambers, disinfectant "dunk tanks" and waste water treatment systems ensure that absolutely everything that leaves the lab is decontaminated.
Interior safety features include:
- Entries and exits with double-door airlocks.
- Regularly decontaminated work surfaces.
- Solid and liquid waste decontamination by heat sterilization, gaseous sterilization, or liquid disinfection. Before it leaves the facility, all waste meets or surpasses the environmental standards of the local community.
- Airtight, pressurized suits with dedicated life-support systems that include redundant breathing air compressors, alarms and emergency backup air tanks, as well as a HEPA air filtration system.
- Work stations (called biosafety cabinets) that serve as additional barriers. With their own inward-directed and HEPA-filtered air systems, these cabinets are designed to prevent potentially dangerous microbes from escaping.
As a testament to the Shope Lab's careful design and construction, it survived Hurricane Ike with minimal damage after the storm made landfall in Galveston on September 13, 2008. Hurricane Ike arrived as a Category 2 storm on the Saffir-Simpson Scale, with sustained winds of 108 miles per hour and a storm surge of 13.5 feet.
