Summary of Meeting Paper

The 1996 Annual Meeting of the Society for Risk Analysis-Europe

Emergency Awareness in Planning. Karl G. Palmér, The National Board of Civil Emergency Preparedness, Stockholm, Sweden

The vulnerable society

The trend towards largeness of scale, automation, specialization and globalization has led to an increase in complexity. Systems are large and interdependent. Failure of one system causes repercussions in other systems, thus increasing our vulnerability still further.

The number of risks has increased. If we can identify and deal with risks in peacetime, this will stand us in good stead in an emergency or war.

Emergency awareness in planning and development

Therefore Sweden's parliament decided in the mid 80's to introduce emergency awareness as a factor in planning and development. It is the task of the National Board of Civil Emergency Preparedness to get this message across and initiate implementation on a wide front. Thinking in terms of emergency awareness means that in developing the peacetime infrastructure which is crucial to survival in an emergency or war we must seek solutions aimed at:

Risks and threats

The number of risks has increased. A risk may be defined as the probability of a certain (undesirable) event occurring and the consequences this entails. Due to the increase in number of risks and in technical complexity the probability of undesirable events has also increased. But worse still, the consequences of these events are now much more serious than before.

The durability of the peacetime infrastructure

In the old days it was easier to define the difference between peace and war. Today we can perceive threats as lying somewhere along a scale from peace and normality to war and destruction, the ultimate threat being that of a nuclear war.

Costs

It is generally thought that allowing for emergency preparedness factors will involve increased costs. However, this is not necessarily the case. In fact , solutions incorporating the emergency preparedness concept may be cheaper, as expensive or more expensive than conventional solutions. In some cases the emergency preparedness approach results in cheaper solutions because risk assessment brines to light a planning angle that would otherwise have been overlooked.

Often a more durable construction may cut operation and maintenance costs, thus reducing the total costs.

Emergency awareness in planning - when

Three key principles are to be observed in planning for taking emergency awareness.

* Location. What is the most appropriate site for a building or system in the country/county/area or in relation to existing buildings or plants?

* Design. What is the most appropriate design, what materials should be used, how should the different functions be located in relation to one another? Should part of the construction be built for greater security and strength?

* Equipment. What equipment best meets durability and flexibility requirements? Should additional equipment be incorporated as a reserve in the event of stoppages or disruption?

Responsibility

Everybody who is involved in transformation of the society in to future has a responsibility to be aware of risks and threats that should be taken into account. There is a possibility - when making changes in the society - to step by step build a more secure and sustainable society.

The technical development

The technical development and the economical assessments are changing more and more rapidly. This may give us new risks and threats, but very often they give us possibilities to handle old ones. What was technically impossible yesterday, is possible today and a good business tomorrow.

One example is the latest technology for rock drilling. Today's giant drills make it possible to drill tunnels through rock at an increasingly competitive price. The real cost of rock drilling tends to diminish over time, while the cost of concrete structures on land or in the air tends to increase. Therefore, tunnels may in time become an increasingly attractive solution for planners. Tunnels are, incidentally, considerably more durable.

Risk-analyses

Risk analyses are a good help to find the risks involved in a system, a plant or a building. They are basic data in the planning process. In Sweden we are developing several risk analyses in separate sectors of the society.

Results

This concept has now been developed for some years and has reached a rather wide spreading. In Sweden there are a lot of good examples, especially in electricity, telecommunications, transportation systems and much more.

We are living in a time of rapid technical development. That gives us new risks but even -- and may be to a higher decree -- new possibilities to treat risks and threats.
