PART 112--EMERGENCY LIGHTING AND POWER SYSTEMS--Table of Contents
 
                     Subpart 112.15--Emergency Loads
 
Sec. 112.15-1  Temporary emergency loads.


    On vessels required by Sec. 112.05-5(a) to have a temporary 
emergency power source, the following emergency lighting and power loads 
must be arranged so that they can be energized from the temporary 
emergency power source:
    (a) Navigation lights.
    (b) Enough lights throughout machinery spaces to allow essential 
operations and observations under emergency conditions and to allow 
restoration of service.
    (c) Lighting, including low location lighting if installed, for 
passageways, stairways, and escape trunks in passenger quarters, crew 
quarters, public spaces, machinery spaces, damage control lockers, 
emergency equipment lockers, and work spaces sufficient to allow 
passengers and crew to find their way to open decks and to survival 
craft, muster stations, and embarkation stations with all watertight 
doors and fire doors closed.
    (d) Illuminated signs with the word ``EXIT'' in red letters 
throughout a passenger vessel so the direction of escape to the open 
deck is obvious from any portion of the vessel usually accessible to the 
passengers or crew, except machinery spaces, and except stores and 
similar spaces where the crew are not normally employed. There must be 
sufficient signs so that the direction of escape is obvious, with all 
fire doors in stairway enclosures and main vertical zone bulkheads 
closed and all watertight doors closed. For the purpose of this 
paragraph, an individual stateroom or other similar small room is not 
required to have a sign, but the direction of escape must be obvious to 
a person emerging from the room.
    (e) Illumination to allow safe operation of each power operated 
watertight door.
    (f) At least one light in each space where a person may be 
maintaining, repairing, or operating equipment, stowing or drawing 
stores or equipment, or transiting, such as public spaces, work spaces, 
machinery spaces, workshops, galleys, emergency fire pumprooms, bow 
thruster rooms, storage areas for paint, rope, and other stores, 
underdeck passageways in cargo areas, steering gear rooms, windlass 
rooms, normally accessible duct keels with valve operators, cargo 
handling rooms, and holds of roll-on/roll-off vessels.
    (g) Lighting for survival craft launching, including muster 
stations, embarkation stations, the survival craft, its launching 
appliances and the area of the water where it is to be launched.
    (h) Electric communication systems that are necessary under 
temporary emergency conditions and that do not have an independent 
storage battery source of power.

    (i) Each power operated watertight door system.
    (j) All shipwide communications systems necessary for the 
transmittal of information during an emergency.

    (l) Supply to motor generator or other conversion equipment if a 
temporary emergency power source of alternating current is necessary for 
essential communication systems or emergency equipment.
    (m) Each daylight signaling light.
    (n) Each smoke detector system.
    (o) Each electrically controlled or powered ship's whistle.
