Fire signage history and disasters

What exactly is a sign?  At first glance, that might sound like a strange question. Signs are everywhere: telling us where to go, what to do, what not to do, and sometimes what might happen if we ignore instructions. But as my guest, Jeffrey Ludlow Saentz explains, signs are much more than bits of information on walls or beside roads.

Episode Summary
Jeffrey is a signage designer who works on complex buildings and environments around the world — airports, offices, museums, and other places where helping people find their way really matters. He’s also the author of A Sign Is..., a fascinating book exploring the history, meaning, and cultural significance of the signs that shape our everyday behaviour.

In this conversation, we explore why good signage is often invisible, how buildings “speak” to us through wayfinding systems, and what signs reveal about power, trust, and human behaviour. Along the way we discuss hacked traffic signs, casino design, airport navigation, and why something as simple as an arrow carries centuries of history.
