Colloquium Speaker Richard Cook Examines Why Accidents Happen|
Richard Cook, director of the Cognitive Technologies Laboratory at the
University of Chicago, declares that the "holes" in a system, and
not human error, rank as the leading cause of accidents in large complex systems such as healthcare, aviation and transportation.
In last Wednesday's Colloquium, Cook explained that a complex system has many layers of defense against accidents. Each layer contains "holes," or failures; accidents occur on the rare occasions when the holes line up. Why is human performance blamed in 85% of accidents when it is only one of the layers of defense? Cook cited hindsight bias: When an outcome is known, the pathway to that outcome seems obvious. In accidents, human performance immediately beforehand is the obvious point to criticize--but not necessarily the right one.
"I didn't give you a way to prevent accidents in this talk," Cook concluded, "but I might have given you a new way of looking at accidents after they occur."

Fermilab Design: Past, Present and Future|
Fermilab Today begins a series on design at Fermilab, from Robert Wilson's original vision to current updating efforts.
Extending Wilson's Legacy

Founding director Robert Wilson's vision for Fermilab and the colors,
sculpture, landscape and architecture that he and graphic artist Angela
Gonzales chose in the early days of the laboratory have left a strong
legacy of design. Fermilab's Design Task Force is working to preserve
and extend that legacy with guidelines for all aspects of the Fermilab
site--and its Web site.
"Wilson saw a real connection among science, technology and the arts,"
said Ed Crumpley, co-chair of the task force and manager of engineering
in FESS. "He and Gonzales teamed up to develop the overall level of
The task force, created by Fermilab Director Mike Witherell, convened in the spring of 2001 with the goal of
unifying design at Fermilab, including the Web site.
The task force and its
subcommittees have so far addressed colors, typefaces, signs,
Web site design, exhibits and displays in Wilson Hall.

Burning season strikes prairie
'Tis the season to burn.Every year in early spring, prairie restorers wait for a nice day to light the fires that breathe new life into the landscape.
"The goal is to create as much of a natural habitat as possible," said Drew Ullberg, the Kane County Forest Preserve District's director of planning.
For four to six weeks starting in the middle of March, plumes of smoke will rise from prairie projects as the forest preserve district, park districts and Fermi National Accelerator Laboratory perform the annual ritual.
Watch Your Step|
|Most stair injuries can be prevented by simply holding onto the railing. (Click on image for larger version.)|
You're waiting for the elevator on the fifteenth floor of Wilson Hall. You
have coffee in one hand and a notebook in the other. That 9:00 a.m.
meeting is about to start on the eighth floor, and the elevator is taking
forever. You give up waiting and decide to run down the stairs
to save time. Crash.
Since 1982, Fermilab has had 43 recordable work injuries that
in some way involved stairs. Although they accounted for
only 2 percent of the total injuries, the associated losses tend to be
on the high side.
Eighty-eight percent of the occupational injuries occurred while
traveling down stairs and 72 percent were located inside a building.
Slipping, mis-stepping and tripping were the main causes. Carrying something,
slippery surfaces and rushing were contributing factors.
Only two of the five "slippery surface" cases involved ice.
The most common accident locations were Wilson Hall, DZero
and buildings in the Industrial Area.
The best way to prevent stair injuries is to pay
attention to your path of travel, make sure you have good footing,
hold onto the railing and do not rush. Regular cleaning and maintenance
will also help lower the number of injuries that occur on stairs.
Have a great day and let's work safely all week!

- During this period Operations established two stores. Those stores
combined with an existing store provide the experiments with approximately 35 hours and 27
minutes of luminosity.
- The Tevatron suffered a six-house quench and then a multi-house
