HAZARD CONTENTS AREA [IBC §1010.1.2].

EXIT CAPACITY

THE EGRESS/EXIT CAPACITY FOR AN EXIT IS DETERMINED BY DIVIDING THE CLEAR WIDTH OF THE EXIT COMPONENT BY THE EGRESS CAPACITY

FACTOR.

HORIZONTAL COMPONENTS OF THE EGRESS PATH ARE MARKED BY APPROVED EXIT OR DIRECTIONAL EXIT SIGNS WHERE THE CONTINUATION OF THE EGRESS PATH IS NOT OBVIOUS [IBC §1013.1]. EXIT SIGNS ARE PLACED SO THAT NO POINT IN AN EXIT ACCESS CORRIDOR EXCEEDS THE RATED VIEWING DISTANCE OR 100 FT, WHICHEVER IS LESS, FROM THE NEAREST SIGN [IBC §1013.1].

THE FACE OF AN EXIT SIGN ILLUMINATED FROM AN EXTERNAL SOURCE SHALL HAVE AN INTENSITY OF NOT LESS THAN 5 FOOTCANDLES (54 LUX) AND

SHALL HAVE A CONTRAST RATIO OF NOT LESS THAN 0.5 [IBC §1013.6.2].

EXIT SIGNS SHALL BE ILLUMINATED AT ALL TIMES. TO ENSURE CONTINUED ILLUMINATION FOR A DURATION OF NOT LESS THAN 90 MINUTES IN CASE OF PRIMARY POWER LOSS, THE SIGN ILLUMINATION MEANS SHALL BE CONNECTED TO AN EMERGENCY POWER SYSTEM PROVIDED FROM STORAGE
