An industrial product is conventionally considered safe as long as its failure effects are unlikely to

endanger solely man life and his properties. FMEA (Failure Modes and Effects Analysis) is an

assessment comparative technique adopted by a certain production plant in order to monitor any

progress achieved in its product safety. The present study, however, proposes a more comprehensive

sense of the product safety so broadened as to also avoid detrimental effects on all living creatures and

natural resources in the global Environmental System (ES). Accordingly, the safety measures

traditionally used in the FMEA technique are carefully revised and properly reformulated here in order

to define their new environmental counterparts.

In addition to using the conventional time domain, the study adds three graphical domains suitable to

display the FMEA measures. Thus, successive reductions in safety threats and risks owing to elaborate

design efforts are readily illustrated as a series of changing geometric forms. Each one of such domains

displays both the overall threat as well as its main components; being the occurrence, the detection, and

the severity.

As an application of the suggested approach, the safety of automobiles as an indispensable industrial

product is investigated to estimate its so far known adverse impact on two entities of ES; being man and

air. It is found that the fast-paced knowledge constantly discovers hidden or overlooked automobileinvoked

threats that call for incessant design innovations and strict implementation policy.
