communication

It was only two years ago that Hurricane Katrina pounded the Gulf
Coast, leaving utter destruction in its wake. When the levees broke, so
did the communication system within the city of New Orleans.
Infrastructure was gone, 911 service and public safety radio were
eliminated, the state of Louisiana’s high-dollar radio system died, and
cell phone capabilities were limited. Some people resorted to
handwritten messages, which were placed in bottles and dropped from
helicopters to the ground, according to Louisiana State Senator Robert
Barham. Amateur radio provided one of the few remaining communication
systems during and after the hurricane.
The Hospital
Emergency Amateur Radio Team sets up a disaster tent and communication
equipment for the annual field day exercise held last month outside the
ER behind the health science library.
A resulting lesson from Katrina is the need for a reliable
communication system among first responders, emergency management
agencies and local hospitals during disasters. Amateur radio, also
known as “ham” radio, is an independent communication system created
and maintained by federally-licensed volunteers. Dozens of MUSC faculty
members and staff are licensed to carry these hand-held devices and
manage the additional equipment owned by the hospital as a result of a
federal grant. The Hospital Emergency Amateur Radio Team (HEART)
participated in an annual field exercise in late June that tested
capabilities and operations under conditions similar to a catastrophic
event like a hurricane, earthquake or tsunami.
“If we have damaged infrastructure, we have to rebuild; but we also
need some basic communication,” said drill participant John Welton,
Ph.D., R.N., associate professor, College of Nursing.
Dr. Steven Saef,
Emergency Medicine, operates the Morse code key to send out emergency
signals during the communication exercise.
Ham radio operators also use different modes and frequencies and have
access to a wider range of service than Citizens Band (CB) radios that
can be purchased at local hardware stores. In addition to hand-held
devices, two radio repeaters are positioned on top of Rutledge Tower to
extend the reach of broadcasts to other HEART members throughout the
state.
In the event repeater antennas become damaged by high winds, the team
also tested a high-frequency radio that would function as a reserve
communication system, connecting MUSC with other regional and national
personnel. This temporary set-up includes a long wire strung high
across two nearby trees, which is only done when all other means of
communication have failed.
“Amateur radio is a ‘safety net’ for existing public safety radio
systems when they become overwhelmed or damaged. MUSC and other area
hospitals now have the capability to communicate locally and throughout
the state,” said Welton.
The “Field Day” was considered a success, especially the coordination
and participation of campus volunteers. The communication exercise was
part of an overall disaster drill in which tents were erected near the
emergency room and behind the health science library. This spacious
working condition provided proximity to patient care, which would be
beneficial during recovery efforts.
“We set up the tents; we set up the wire in the trees,” said Welton.
“It isn’t pretty, but it works.”
Though the simulation identified several strengths, concerns remain
regarding the ability to maintain electricity for communication and the
availability of operators. A small number of portable generators are
available on campus, and the team is looking into the use of solar
power as an alternative energy source, because it could support the
entire communication effort during an emergency. The presence of radio
operators depends on the type of hazard and the extent of damage. A
second component of the grant is to train hospital and other campus
personnel to get their amateur radio license. Amateur radio is not
meant to replace other emergency communication systems; rather, it is
simply another viable option that’s cost-effective and highly
successful.
For more information on how to obtain a “ham” radio license, or already
licensed operators wanting to join the MUSC HEART program, contact
Welton at weltonj@musc.edu or Brian Fletcher, R.N., Clinical Services
Disaster Preparedness coordinator at the hospital (fletche@musc.edu).
