Exit Signs One Foot off the ground it makes sense in Mt Lebanon and other towns who reccomend it.

 If your ever in the Mt Lebanon Pa area or in some other towns you will find a strange sight in Office Buildings where there are 2 exit signs at doors one above and one below  as can be seen in the below picture

Now you might think what sense does it make putting one so low? Well there is a dam good reason and I agree with Mt. Lebanon and other depts who enforce this code 

Your in a building the alarm goes off as you enter the middle of the hallway it is filled with smoke which way do you go? You cant see a thing its all smoke .

You get down on your knees like fire experts recommend and what do you see when you look down the corridor that low hanging sign  because smoke tends to stay off the floor as it starts building .

You make it to safety instead of guessing and guessing wrong . I commend the efforts of Mt Lebanon and other towns who encourage the use of these lowered  exit signs .

Although they can be a pain to install in existing buildings its well worth the effort
