It is almost impossible to build a completely safe product or one that will never fail. When there is a failure of the product SAFE EXIT should be provided.

Safe exit is to assure that

i) when a product fails, it will fail safely,

ii)  that  the product  can be abandoned  safely and  iii)  that  the  user can safely escape  the product.

More than the questions of who will build, install, maintain and pay for a safe exit, the most important question is who will recognize the need for a safe exit. This responsibility should be an integral part of the experimental procedure.

Some examples of providing ‘SAFE EXIT’:

•   Ships need lifeboats with sufficient spaces for all passengers and crew members.

•   Buildings need usable fire escapes

•    Operation  of  nuclear  power  plants  calls  for  realistic  means  of  evacuating  nearb y communities

•   Provisions are needed for safe disposal of dangerous materials and products.

Colleagiality & Its Elements

‘Collegiality is a kind of connectedness grounded in respect for professional expertise and in a commitment to the goals and values of the profession and as such, collegiality includes a

Disposition to support and co-operate with one’s colleagues’.

– Craig Ihara

The central  elements  of  collegiality  are  respect,  commitment,   connectedness   and  co- operation.

Respect: Acknowledge the worth of other engineers engaged in producing socially useful and safe products.

Commitment: Share a devotion to the moral ideals inherent in the practice of engineering. Connectedness:  Aware  of  being  part  of  a  co-operative  undertaking  created  by  shared commitments and expertise.

Collegiality, like most virtues, can be misused and distorted.

It should not be reduced to ‘group interest’ but should be a shared devotion for public good.

It is not defaming colleagues, but it does not close the eyes to  unethical practices of the co-professionals, either.
