Gday all,
It was asked of me today, by someone of greater than average intelligence and common sense, why the standard colour for Emerg. Exit lights and signage in aeroplanes is red when the Aussie standard for buildings is green??
I still haven't been able to come up with a reasonable answer. I proposed that perhaps red light penetrated smoke better or that perhaps the standard for Emerg. Exit lighting in the USA was red.
Anyone able to offer a reasonable answer
Cheers,
I'm gone!
