Well-designed safety symbols look simple, but getting there is anything but. This column examines how ISO's graphical symbol standards guide the redesign of shipboard safety icons, from assembly points to radiotelephone markers, and why engineers should build on established symbol elements rather than start from scratch.
Hazard Based Safety Engineering (HBSE) principles have been used to better understand product safety and to help guide the design and evaluation of appropriate safeguards through analysis of sources, causes and mechanisms of harm. UL Applied Safety Science and Engineering Techniques (ASSETTM) takes HBSE to the next level.
This article dispels some of the misconceptions surrounding inductance and to encourage electrical engineers to think more clearly about these physics.
