We'll forgive the lack of punctuation. But was the situation so urgent "emergency" had to lose its G?
(We also sort of wonder if there are stairs besides the "exit stairs." Are there entrance ones? Are they reminding people to go toward the exit to get out of the building, instead of toward, say, the roof? Sometimes, one can over-explain. Sort of like we're doing right here.)
