## Signs shall be suitable for the service environment of their installed location, including interior conditioned, wet, vandal-prone, and covered-exterior conditions as applicable.
−## Signs in wet or washdown locations — locker rooms, pool enclosures, covered exterior walks — shall use corrosion-resistant substrates and fasteners and shall carry a wet-location rating where the product type requires one. {note}
−
−## Photoluminescent exit signs depend on ambient light to charge; they shall be installed only where the ambient illumination at the sign face is maintained at a minimum of 1 fc during all hours of occupancy.
−
−## A photoluminescent sign in a dim, windowless, or intermittently lit corridor will not charge to its rated luminance and will fail to perform in a power loss; ambient light verification is a precondition of using this product type, not an afterthought. {note}

## Internally illuminated exit signs shall be illuminated continuously during building occupancy and shall meet the illumination requirements of their UL 924 listing; externally illuminated signs shall be illuminated to not less than 5 fc on the sign face.
−## Each illuminated exit sign shall be provided with a backup power source that maintains rated illumination for not less than 90 minutes after loss of normal power and re-energizes to full output within 10 seconds of a power failure.
−
−## The 80% configuration for most projects is an LED internally illuminated exit sign with a red legend, dual 120/277V input, and an integral 90-minute battery; this satisfies nearly all AHJ requirements without special approval and is the default unless project conditions dictate otherwise. {note}
−
−## For sign-face and color selection: IBC does not mandate a legend color and NFPA 101 permits both red and green, but many state amendments and local fire marshals require red — confirm the permitted color with the AHJ before procurement where green is contemplated; double-face signs are used where the sign is viewed from both directions of a corridor or is ceiling- or blade-mounted in an open path, while single-face signs are used against a wall or at a terminal door. {note}

### Where a sign carries a pictogram — accessible symbol, restroom, stairway — the pictogram shall be located in a field above the tactile characters, and the pictogram field shall not contain raised characters or Braille.
