Remarks of Jim Hall, Chairman
National Transportation Safety Board
at the Joint American Petroleum Institute GCMT/USCA Industry
Workshop
New Orleans, Louisiana, June 26, 1997
Thank you for inviting me here today.
You know the Safety Board for its high-profile investigations
like the crash of TWA flight 800 last year, or the derailment
of Amtrak's Sunset Limited in Mobile, Alabama a few years back.
Much of our work involves nuts-and-bolts documentation of wreckage
and accident scenes, but much of our work also involves delving
into more subtle areas of inquiry, sometimes leading us into management
suites, or even corporate boardrooms.
What I'd like to discuss with you today is an area that is only
recently gaining currency in many corners of our transportation
industry, the issue of "Corporate Culture" and its affect
on transportation safety.
Although "corporate culture" has provided either negative
or positive reinforcement on operational safety since the dawn
of the industrial age, I'd like to open this discussion with one
of the most famous examples of the negative influences corporate
culture can exact on safety.
Eighty five years ago, mankind's belief in the infallibility of
its work bore its terrible and inevitable result. The loss of
the RMS TITANIC demonstrated the folly of management overconfidence
in its operation, leading to its failure adequately to prepare
for predictable, if unwelcome, events. But why would the finest
ocean liner the world had ever seen at that time fall victim to
such failures?
Granted, there was a regulatory culture that allowed these things
to happen, but where was the conscience, or just the common sense,
of company management? Just because the TITANIC was allowed to
have so few lifeboats, did no one at the company consider the
ramifications should the lifeboats be needed?
The fact that this calamity occurred on her maiden voyage I think
was the ultimate irony and a monument to individual arrogance,
but at the tragic loss of 1,500 lives. Yes, it was Captain Smith
who refused to reduce his speed, but if investigators had stopped
there, then we would surely have seen a repeat of that catastrophe.
We wouldn't have had the imposition of ice patrols on the Atlantic,
or international requirements for lifeboats to accommodate an
entire ship's complement, for example. The loss of the TITANIC
was a good example that the proximate cause is not the same as
the probable cause; we must dig deeper to get to the true safety
issues.
As you may know, the National Transportation Safety Board is the
nation's independent accident investigation agency, with authority
to investigate aviation, marine, highway, railroad, pipeline and
hazardous materials accidents. Our mission is to learn exactly
what happened in these accidents and why they occurred, to determine
causes and contributing factors. We are mandated to make those
findings public, and, most important, to issue safety recommendations
aimed at eliminating future accidents, deaths and injuries.
These recommendations are directed to carriers, equipment manufacturers,
unions, oversight agencies and professional associations in all
modes of transportation that can set standards or otherwise communicate
our safety messages to their members. We do all this with a very
small staff - 360 people - and a budget of about $40 million.
Our yearly budget would fund the Department of Transportation
for 9 hours of a single day. At an annual cost of 15 cents per
citizen, I think the Safety Board is the best bargain in government.
An accident, which represents a major failure of the operating
system in which it occurred, often results from a combination
of circumstances. These circumstances can range from mechanical
failures to environmental conditions to human errors to organizational
failings. Let me paraphrase one of my former colleagues on the
Board, Dr. John Lauber, who said that the absence of accidents
does not necessarily indicate the presence of safety.
The safer carriers that we see across the transportation modes
have more effectively committed themselves to controlling the
risks that may arise from each and every one of these factors.
The possibility of these factors affecting safety must be anticipated
and safeguards must be systematically developed and implemented.
All other things being equal, the better this is done, the safer
the carrier will be, and the accident statistics will reflect
these conditions.
The Safety Board is in a unique position because for 30 years
we have been the eyes and ears of the American people at accident
sites. We are a national archive - funded by the taxpayer - of
what not to do, to provide lessons so that the same mistakes are
not made over and over again. As the federal government's only
multi-modal accident investigation agency, we have worked with
industries and regulators covering the entire spectrum of our
nation's massive transportation network. We have had the opportunity
to examine the corporate cultures of our largest transportation
suppliers, and many of our smallest.
What is corporate culture? Let me suggest that it might be defined
as stable characteristics of one company or organization that
distinguishes it from another organization. Or, put more plainly,
"the way things are done around here."
Although the Board might not describe "corporate culture"
per se in its reports, it does investigate, and always has investigated,
how culture may have set the stage for accidents. We look at management
practices, policies and attitudes. And while we use the term "management"
broadly, we understand that the best management in the world cannot
overcome the influences of a corporate culture that is bent on
emphasizing other attributes over safety.
As our knowledge and understanding of the role of corporate culture
has improved, our investigations have evolved to encompass more
than just management. It takes the full cooperation and dedication
of every level in an organization to produce an atmosphere where
safety is given pre-eminent status in a corporation's strategic
planning.
As I said, the Board recognizes that accidents are not usually
caused by one solitary factor, nor do they occur in a vacuum.
Safety and accident prevention is everyone's concern and responsibility:
One of the earliest Safety Board recommendations on corporate
culture was issued in 1968, our second year of existence, to the
Federal Railroad Administration. Following a review of a number
of railroad accidents, we told the FRA that we believed that the
primary responsibility for improved railroad safety should rest
upon railroad management and labor. Our recognition then that
safety and accident prevention are the responsibility of management,
the individual workforce and government, holds true today.
But how should management fulfill its responsibility to assure
safe operation? One role for management is to develop, nurture
and maintain a healthy and safe corporate culture. In our practice
of accident investigation at the Board, corporate culture issues
fall within the organizational factors area. In the most elementary
terms, we have treated the culture of any given transportation
organization as their collective mindset. Let me give you a specific
situation that defines the sort of mindset I'm referring to.
Consider this scenario: A transit train operator stops the train
between stations and in doing so successfully avoids endangering
the train and its passengers. However, stopping the train without
permission violates an operating procedure. The operator calls
the dispatcher to obtain permission but is told not to stop. He
stops anyway.
But now, by stopping and avoiding the danger, the operator has
no way to prove that an unsafe condition actually existed. The
question is, what action does his superior take? Is the train
operator disciplined reflexively for his disregard of the rules,
or is he recognized for his alertness. I'll talk more about this
situation when I describe an accident where an operator had to
make just such a choice and he elected to conform to established
procedures, with tragic results.
We at the Safety Board acknowledge that there are different ways
to describe corporate culture; let me suggest one possible way
of describing its basic components:
In our practice of accident investigation, we have found this
concept useful.
Unlike some causal factors, it is not easy to identify corporate
culture problems in the early days after an accident. For instance,
it can be apparent soon after a train derailment that perhaps
a broken rail initiated the accident. But it takes additional
information and analysis to conclude that the train derailed because
management had decided to postpone replacement of the defective
rail.
As a matter of good investigative practice, it is never assumed
that any accident operator's actions occurred in isolation. Each
driver, engineer, pipeline operator or ship's officer performs
the job in an environment of policies, procedures, operating limitations
and operating latitudes.
One indicator for recognizing potentially unsafe cultures is management
thinking and practices that are antagonistic or indifferent toward
their employees in safety sensitive jobs. Another indicator is
an organization's practices that vary from the accepted standards
found in the industry. Third, an unsafe culture may exist if it
is determined that an employee's operating performance conformed
to carrier procedures or reflected the accepted values and attitudes
found in the carrier and an unsafe situation still occurred.
Let me give you an example. Years ago our assessment of corporate
culture focused primarily on whether management actively discouraged
their operators -- in aviation, that would be pilots -- from following
the established company and government rules and procedures. Yet,
considering how much we have learned about corporate culture,
it is difficult to accept the fact that accidents occurred because
some companies actually encouraged rule breaking. For example,
on May 30, 1979, a DeHavilland Twin Otter, operated by Downeast
Airlines, a regularly scheduled commuter flight from Boston, crashed
near Rockland, Maine, while the pilot was attempting to land in
restricted visual conditions. Both pilots and all but one of the
16 passengers were killed in the accident.
The investigation found that the visibility was so poor that the
pilot could not have been able to see the airport at the point,
known as the decision height, at which he was required to abandon
the approach if he could not see the airport. Why then did he
attempt to land anyway, given the known hazards and prohibitions
against such attempts? Well, further investigation found a corporate
culture in place at that airline that not only did not enhance
safety but actively discouraged it. The owner of the airline,
who as president directed its day to day operations, conveyed
to the captain and to all pilots his expectations that they would
cut corners in the interest of saving money. In fact, he criticized
and threatened them when they did not.
The lessons of this accident were unmistakable: a management climate
that pressures pilots to ignore flight rules and safe operating
practices, and threatens pilots if they do not conform to these
practices, adversely affects the safety of the operation.
I want to offer you another example of corporate culture providing
a negative influence on safety, the fatal collision on the Washington,
D.C. Metrorail system in the Maryland suburbs. I alluded to this
accident earlier.
For those of you who have not heard about this accident, it was
a collision in January 1996 between two trains on Metro's Red
Line. A moving train struck an unoccupied standing train that
was not in service, killing the operator of the moving train.
This accident provided for our investigators markers of an organizational
culture that considerably detracted from safe rail transit operation.
At first, it appeared that a train operator simply did not comply
with his training. Then different pictures emerged suggesting
that a superintendent at the train dispatching facility ignored
warnings and did not stop the train. Later still, it appeared
that an executive manager had acted capriciously when he changed
a long-standing operating policy without consideration of the
consequences.
This accident resulted not from singular actions but from an organization-wide
set of beliefs held about the infallibility of the automatic train
control equipment, somewhat reminiscent of the perceived infallibility
of an ocean liner's watertight compartments so many years ago.
The Metro accident occurred shortly after a major snowstorm had
begun and trains had started to overrun station platforms at several
of the above-ground stations. The accumulating snow and ice reduced
the effectiveness of the train's braking system. All trains were
operating in the fully automatic mode; that is, they were being
controlled by the system computer, not by the operator on board
the train or by controllers in the system's central control facility.
Shortly after emerging above ground on its way to Shady Grove
station, train 111 arrived at Twinbrook Station 12 minutes before
the accident. Although the automatic train control directed the
train to stop at the platform, the train did stop, but completely
overran the platform.
At Rockville, too, the train partially overran the station. Because
the operator had to secure the controls to assist passengers at
that station, the train had lost its automated command to operate
at the reduced speed of 44 mph. So, after departure from Rockville,
the train began accelerating automatically beyond that speed,
heading for 75 mph, still within the design limitations of the
rails and signals, at least when weather conditions were favorable.
The operator called the controller to report the over-speed situation
and was told that this was due to his overrunning the previous
station and that he was to continue in automatic operation.
As the train approached the Shady Grove station, the controller,
who could see the location of the train on his monitor, called
the operator and asked if the speed had dropped. Because it had,
the controller later told Safety Board investigators that he had
a feeling the system was doing what it was supposed to do and
didn't believe that he had to put his job on the line by telling
the operator to go into manual mode.
At Shady Grove station, a gap train was parked 470 feet beyond
the platform on the same track that the accident train was using.
A gap train stands by to fill in for unexpected needs, such as
when a scheduled train breaks down. It was parked there despite
an unwritten Metrorail order that these trains were to be kept
on the adjacent inactive track.
You must know what happened next. When train 111 arrived at the
Shady Grove station, it slid past the platform and struck the
standing gap train. The operator was found crushed in wreckage
near the cab door. There were no other injuries.
The Safety Board investigation team was launched that night. Once
the follow-up investigation work began, a fairly clear picture
emerged for what had happened and why. Here are several of the
findings from our investigation that explain the accident and
also have a direct connection to the organizational and management
issues of interest to us today.
It would be tempting to blame the conditions and circumstances
of this accident on one person, the Deputy General Manager. But
this would not have recognized corporate culture as a safety problem.
The logic for substantive causation of this accident only holds
together when we consider the extent to which management and operating
personnel believed the automated train control system would protect
them, and that the system would provide adequate margins of safety
regardless of the quality of the decisions and policies. Again,
I am reminded of the mindset at the White Star Line leading up
to the TITANIC disaster.
We made 20 recommendations to the Metrorail Authority as a result
of the Shady Grove accident. Earlier this year, I met with Metrorail
officials to discuss the actions on the Safety Board's recommendations
from this accident, and it was apparent that major changes in
Metrorail management and in their operating practices were taking
place. Frankly, I was impressed by the aggressiveness of Metrorail
management's actions on many of our recommendations, and at this
time we have every reason to believe there will be an effective
follow-through.
If you look at all of the accidents I've cited, their root causes
go beyond a mere lack of planning or poor personnel decisions.
Each of the accidents were set up by one or more of the following
characteristics:
There are a myriad other accidents that illustrate corporate culture
failings in all modes of transportation; tragedies like the Ledger,
Montana head-on train collision in 1991; the Brenham, Texas salt
dome petroleum storage facility explosion in 1992; the crash of
an FAA aircraft in 1993; and the Fox River Grove grade crossing
accident in 1995. Through our investigations of these and other
accidents, our understanding of the role of management in the
safety of their organization's operations has increased.
We and the transportation community have come to recognize that
management has responsibility for creating and fostering a climate
that encourages safe operations. The purpose of your workshops
today are for you to learn more about how best to ensure that
a climate of safety remains paramount in your organizations' corporate
cultures. I was very interested in this morning's exercise and
I'm sure you all will benefit from the workshop this afternoon
on Lessons Learned from Accidents. Marjorie Murtagh, the Chief
of the Safety Board's Marine Division, will brief you on two major
accidents we investigated.
Your presence here is important, not just because many of you
are leaders of your organizations, but because you will have to
be leaders of the maritime industry. The practice of good corporate
culture is not just good for safety, it is good for business.
But you will have to show the way for others, because it only
takes one or two bad apples to sully the reputation of an entire
industry.
Thank you for inviting me.
