Emergency lights are standard in new commercial and high occupancy residential buildings, such as college dormitories. Most building codes require that they be installed in older buildings as well.

Famous quotes containing the words emergency and/or light:
“In this country, you never pull the emergency brake, even when there is an emergency. It is imperative that the trains run on schedule.”
—Friedrich Dürrenmatt (1921–1990)
“But seldom the laurel wreath is seen
Unmixed with pensive pansies dark;
There’s a light and a shadow on every man
Who at last attains his lifted mark—
Nursing through night the ethereal spark.
Elate he never can be;
He feels that spirits which glad had hailed his worth,
Sleep in oblivion.—The shark
Glides white through the phosphorus sea.”
—Herman Melville (1819–1891)
