Talk:Exit sign
From Wikipedia, the free encyclopedia
How does that explain anything or is at all helpful?
Red or Green
- In some countries, Exit signs are red, because Emergency vehilces (fire engines) are red.
- In Australia, Exit signs are green, because they are the way to go in an emergency.
Red or Green
I was doing some research for a friend on safety when she asked be about exit signs. I looked at this page, as well as the US Department of Labor (OSHA) for reference material. I noticed that there is a statement on this page that "In the US exit signs are both red and green, both colors being legal." I believe that is incorrect.
According to the US DOL site (http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=10681):
"1926.200(d) Exit signs. Exit signs, when required, shall be lettered in legible red letters, not less than 6 inches high, on a white field and the principal stroke of the letters shall be at least three-fourths inch in width."
So there really is not a legal basis for green exit signs in the US. We may need to update this page to make this correction. Ferrett 11:22, 21 April 2006 (UTC)
Actually, the federal government (including OSHA) has no authority over exit signs, as they are controlled by building codes. Building code laws are a shared responsibility of the states and localities; and most states have one set color. I updated the page to reflect this. Eaglescout1984 16:37 29 July 2006 (GMT)
[edit] Edge-lit exit signs
I have noticed that some exit signs are transparent sheets of plastic that are lit from above by LEDs. They can be read from either side, and the word "exit" never appears backward. Here is a link to a picture: http://www.prolighting.com/edlitexsi.html Can somebody tell me how these work? Thanks, Chris Allington cjalling@oakland.edu
Chris, I speculate you are talking about double-faced edge-lit exit signs. Double-faced exit signs have a special mirror placed in between the two faces. That is why the word "EXIT" does not "bleed through" to the other side. Just for the sake of completeness, I think I should mention that tritium exit signs with two faces use practically the same method, those having two separate exit signs screwed together (at least this is how Emergi-Lite assembles their double-faced tritium signs). I hope this information has been helpful to you! Compdude512 13:34, 26 July 2006 (UTC)
[edit] The edit I made...
I removed this weblink: [1] because it referenced it as a "regular" exit sign. Although this is the standard symbol used on American passenger trains, it is used for emergency exits, usually window exits, in much the same way as "EXIT" is used for most exits in buildings.
I ride Amtrak regularly, and I will make an effort to take a picture of such a sign, and maybe the window sign too. I'll explain it in the caption.
