ABSTRACT
The "due care" clause of the principle designates things as apprising oneself of the harm that may result from one's actions, taking precautions to avoid such harm, and being ready and willing to make sacrifices in order to reduce the likelihood of harm. There are a number of mechanisms of support for engineers which society may provide. These include effective government regulation, legal remedies, and the activities of professional organizations willing to take strong measures, such as censure, boycott, and strike. The proper response to all this is to point out that discretionary power is not the only form of control. The harm that results from a dangerous product comes about not only through the decision to employ the design, but through the formulation and submission of the design in the first place. Harm could not come about if the engineers had refused to submit the design when they had good reason to believe that it was dangerous.
