Abstract

The article reviews structural (organic, combinational and cumulative) threats resulting from the expansion and increase in the complexity of technical systems and the contemporary conditions for the operations of such systems and the introduction of technical innovation. Given the growing social aversion to the proximity of technical instalations and industrial products or the growing distructs of scientific safety certificates, the author of the article seeks the answer to a question of whether social fears of harmful effects of technical factors are justified. Based on a theoretical analyses of technical strategies used in safety assessment in selected domains of technical activity, the author of the article demonstrates that some threats from technical factors are cognitively elusive to normal science. The causes are indicated by cognitive limitations, errors, deficienses and abuses that undeterminine the credibiity of scientific safety certificates and prompt the thourough revision of previous cognitive strategies. The author postulates replacing the expert-laboratory procedures of normal science with post-normal models based on agreements with risk exposed persons.
