We saw an essay on Clean Skies that suggests the oil industry could learn from the nuclear industry, in particular, that the oil industry should adopt international standards of practice similar to the nuclear industry’s response to Chernobyl. We totally agree. The one point we would add is that the single most important thing the oil industry could learn from nuclear is the significance of establishing and maintaining an adequate safety culture. Safety culture is the sine qua non of safe, profitable operations in any high-hazard business.
And safety culture has to be real. Beleaguered executives proclaiming that safety is number are simply not convincing when equipment and methods haven’t been tested (or don’t work), and profit has obviously been driving decision-making.
We want to remind the nuclear industry that they are one significant incident away from an even worse political and public relation disaster. As we have said before, the oil industry is not as tightly interwoven in the public mind as nuclear; to date, BP is being vilified in Washington and in the press, but the damage to other companies has been incidental, a temporary stop in issuing drilling permits. The nuclear industry would not get off so relatively easy if an incident of similar magnitude were to occur in their bailiwick.

Why is Nuclear Different?
We saw a very interesting observation in a recent World Nuclear News item describing updates to World Association of Nuclear Operators’ structure. The WANO managing director said “Any CEO must ensure their own facilities are safe but also ensure every other facility is safe. [emphasis added] It's part of their commitment to investors to do everything they can to ensure absolute safety and the one CEO that doesn't believe in this concept will risk the investment of every other.” As WNN succinctly put it, “These company heads are hostages of one another when it comes to nuclear safety.”
I think it's true that nuclear operators are joined at the wallet, but why? In most industries, a problem at one competitor creates opportunities for others. Why is the nuclear industry so tightly coupled and at constant risk of contagion? Is it the mystery and associated fears, suspicion and, in some cases, local visibility that attends nuclear?
Coal mining and oil exploration exist in sharp contrast to nuclear. "Everyone knows" coal mining is dirty and dangerous but bad things only happen, with no wide-ranging effects, to unfortunate folks in remote locations. Oil exploration is somewhat more visible: people will be upset for awhile over the recent blow-out in the Gulf of Mexico, offshore drilling will be put on a temporary hold, but things will eventually settle down. In the meantime, critics will use BP as a punching bag (again) but there will be no negative spillover to, say, Chevron.

“Serious Systemic Safety Problem” at BP
Yes, it’s BP in the news again. In case you hadn’t noticed, the fire, explosion and loss of life last week was at an offshore drilling rig working for BP. In the words of an OSHA official BP still has a “serious, systemic safety problem” across the company. Check the embedded web page for the story.

Safety Culture: Cause or Context (part 1)
As we have mentioned before, we are perplexed that people are still spending time working on safety culture definitions. After all, it’s not because of some definitional issue that problems associated with safety culture arise at nuclear plants. Perhaps one contributing factor to the ongoing discussion is that people hold different views of what the essence of safety culture is, views that are influenced by individuals’ backgrounds, experiences and expectations. Consultants, lawyers, engineers, managers, workers and social scientists can and do have different perceptions of safety culture. Using a term from system dynamics, they have different “mental models.”
Examining these mental models is not an empty semantic exercise; one’s mental model of safety culture determines (a) the degree to which one believes it is measurable, manageable or independent, i.e. separate from other organizational features, (b) whether safety culture is causally related to actions or simply a context for actions, and (c) most importantly, what specific strategies for improving safety performance might work.
To help identify different mental models, we will refer to a 2009 academic article by Susan Silbey,* a sociology professor at MIT. Her article does a good job of reviewing the voluminous safety culture literature and assigning authors and concepts into three main categories: Culture as (a) Causal Attitude, (b) Engineered Organization, and (c) Emergent and Indeterminate. To fit into our blog format, we will greatly summarize her paper, focusing on points that illustrate our notion of different mental models, and publish this analysis in two parts.
Safety Culture as Causal Attitude
In this model, safety culture is a general concept that refers to an organization’s collective values, beliefs, assumptions, and norms, often assessed using survey instruments. Explanations of accidents and incidents that focus on or blame an organization’s safety culture are really saying that the then-existing safety culture somehow caused the negative events to occur or can be linked to the events by some causal chain. (For an example of this approach, refer to the Baker Report on the 2005 BP Texas City refinery accident.)
Adopting this mental model, it follows logically that the corrective action should be to fix the safety culture. We’ve all seen, or been a part of, this – a new management team, more training, different procedures, meetings, closer supervision – all intended to fix something that cannot be seen but is explicitly or implicitly believed to be changeable and to some extent measurable.
This approach can and does work in the short run. Problems can arise in the longer-term as non-safety performance goals demand attention; apparent success in the safety area breeds complacency; or repetitive, monotonous reinforcement becomes less effective, leading to safety culture decay. See our post of March 22, 2010 for a discussion of the decay phenomenon.
Perhaps because this model reinforces the notion that safety culture is an independent organizational characteristic, the model encourages involved parties (plant owners, regulators, the public) to view safety culture with a relatively narrow field of view. Periodic surveys and regulatory observations conclude a plant’s safety culture is satisfactory and everyone who counts accepts that conclusion. But then an event occurs like the recent situation at Vermont Yankee and suddenly people (or at least we) are asking: How can eleven employees at a plant with a good safety culture (as indicated by survey) produce or endorse a report that can mislead reviewers on a topic that can affect public health and safety?
Safety Culture as Engineered Organization
The model is evidenced in the work of the High Reliability Organization (HRO) writers. Their general concept of safety culture appears similar to the Causal Attitude camp but HRO differs in “its explicit articulation of the organizational configuration and practices that should make organizations more reliably safe.” (Silbey, p. 353) It focuses on an organization’s learning culture where “organizational learning takes place through trial and error, supplemented by anticipatory simulations.” Believers are basically optimistic that effective organizational prescriptions for achieving safety goals can be identified, specified and implemented.
This model appears to work best in a command and control organization, i.e., the military. Why? Primarily because a specific military service is characterized by a homogeneous organizational culture, i.e., norms are shared both hierarchically (up and down) and across the service. Frequent personnel transfers at all organizational levels remove people from one situation and reinsert them into another, similar situation. Many of the physical settings are similar – one ship of a certain type and class looks pretty much like another; military bases have a common set of facilities.
In contrast, commercial nuclear plants represent a somewhat different population. Many staff members work more or less permanently at a specific plant and the industry could not have come up with more unique physical plant configurations if it had tried. Perhaps it is not surprising that HRO research, including reviews of nuclear plants, has shown strong cultural homogeneity within individual organizations but lack of a shared culture across organizations.
At its best, the model can instill “processes of collective mindfulness” or “interpretive work directed at weak signals.” At its worst, if everyone sees things alike, an organization can “[drift] toward[s] inertia without consideration that things could be different.” (Weick 1999, quoted in Silbey, p.354) Because HRO is highly dependent on cultural homogeneity, it may be less conscious of growing problems if the organization starts to slowly go off the rails, a la the space shuttle Challenger.
We have seen efforts to implement this model at individual nuclear plants, usually by trying to get everything done “the Navy way.” We have even promoted this view when we talked back in the late 1990s about the benefits of industry consolidation and the best practices that were being implemented by Advanced Nuclear Enterprises (a term Bob coined in 1996). Today, we can see that this model provides a temporary, partial answer but can face challenges in the longer run if it does not constantly adjust to the dynamic nature of safety culture.
Stay tuned for Safety Culture: Cause or Context (part 2).

More Drips on the BP Front
In an article dated March 9, 2010 (“BP Faces Fine Over Safety at Ohio Refinery”) the Wall Street Journal reports on more heavy fines of oil giant BP for safety issues at its refineries. OSHA has levied fines of $3 million for violations at the BP refinery in Toledo, Ohio. This follows record monetary penalties for its Texas refinery last year. What is significant about this particular enforcement action? Principally the context of the penalties - the Obama administration is taking a tougher regulatory line and its impact may extend more broadly, say to the nuclear industry. The White House clearly "wants some of the regulatory bodies to be stronger than they have been in the past," accordingly to the article. It is hard to predict what this portends for nuclear operations, but in an environment where safety lapses are piling up (Toyota et al) the NRC may feel impelled to take aggressive actions. The initial steps being taken with regard to Vermont Yankee would be consistent with such a posture.
The other noteworthy item was the observation that BP’s refining business “is already under pressure from plummeting profit margins and weak demand for petroleum products...” Sometimes the presence of significant economic pressures is the elephant in the room that is not talked about explicitly. Companies assert that safety is the highest priority yet safety problems occur that fundamentally challenge that assertion. Why? Are business pressures trumping the safety priority? Do we need to be more open about the reality of competing priorities that a business must address at the same time it meets high safety standards? Stay tuned.
