Advisory V404.2.4.3 Recessed Doors and Gates.  A door can be recessed due to placement of casework, and other fixed elements adjacent to the doorway.  This provision must be applied wherever doors are recessed.

 

V404.2.4.4 Deck Surface.  Deck surface within required maneuvering clearances shall comply with V302.  Changes in level are not permitted.

EXCEPTIONS:  1.  Doors with coamings providing double ramp access in accordance with V404.2.5.2.1 are permitted to have maneuvering clearances on both sides with running slopes complying with V405.

2.  Doors with coamings providing single ramp access in accordance with V404.2.5.2.2 are permitted to have maneuvering clearances on only one side with running slopes complying with V405.

3.  Slopes not steeper than 1:48 shall be permitted. 

4.  Changes in level at thresholds complying with V404.2.5 shall be permitted.

 

V404.2.5 Thresholds.  Thresholds, if provided at doors and doorways, shall comply with V404.2.5.1.

EXCEPTIONS:  1.  Where doors are required by the administrative authority to have coamings, doors shall not be required to comply with V404.2.5 provided (1) the thresholds are readily removable by employees, (2) the doors are only employee operated, and (3) the weather deck areas accessed by these doors are not open to passengers when the vessel is underway.

2.  Where doors are required by the administrative authority to have coamings and the largest deck is less than 3000 square feet (279m2), doors shall be permitted to comply with double or single ramp access in accordance with V404.2.5.2.

3.  Where doors are required by the administrative authority to have coamings and the administrative authority determines that compliance with V404.2.5.1 is not feasible, doors shall be permitted to comply with double or single ramp access in accordance with V404.2.5.2.

4.  Where required by the administrative authority to meet weathertight door sealing requirements, weathertight doors shall be permitted to have non-beveled thresholds ¾ inch (19 mm) high maximum on the sealing side of the doors, provided the thresholds contrast visually with adjacent deck surfaces either light-on-dark or dark-on-light.

 

Advisory V404.2.5 Thresholds.  Under US Coast Guard regulations and international treaties, certain weathertight doors are required to have raised thresholds (coamings) three or more inches in height that form a watertight barrier at the base of the door.  These coamings help protect the stability of a vessel by reducing the amount of water that may enter the vessel through an open exterior door.  Coamings also improve the survivability of a vessel.  When a vessel has been damaged due to collision or other hazardous action, the coamings allow a portion of the doorway to be submerged without compromising the reserve buoyancy of the vessel.  The draft guidelines set out three configurations of access at doors that are required to have coamings. 

 

In the first configuration, the goal is to work with the applicable administrative authority to allow compliance with door maneuvering clearance (V404.2.4) and threshold (V404.2.5) requirements as specified without using the coaming exceptions.  These clearances and threshold heights would be the same as any accessible door on land.  However, V404.2.5 Exception 4 allows a maximum ¾ inch (19 mm) high non-beveled threshold at weathertight doors where such vertical surfaces are required by the administrative authority to meet door sealing requirements (see Figure V404.2.5).

 

Advisory V404.2.5 Thresholds Exceptions 1 through 3.  Exceptions 1 through 3 permit the second configuration of access which allows readily removable coamings (where permitted by the administrative authority), or double and single ramp access methods.  Exceptions in the maneuvering clearance provisions of V404.2.4 and V404.2.4.4 and ramp provisions of V405.2 and V405.7 permit modification of some requirements to allow installation of either the double or single ramp access methods.  A double ramp access method (see Figure V404.2.5.2.1) has two ramps (maximum slope of 1:12) joining together at the top of a coaming (unless V404.2.5 Exception 4 applies), and the coaming equipped door is required to be automatic.  In general, a single ramp access method (see Figure V404.2.5.2.2) has one ramp on only one side of the door connecting the top of the coaming (unless V404.2.5 Exception 4 applies), and a conforming door threshold on the other side.  The ramp is allowed to have a maximum slope of 1:8 for a 3 inches (75 mm) maximum rise, or 1:10 for a 6 inches (150 mm) maximum rise. 

 

V404.2.5 Exception 4 allows a maximum ¾ inch (19 mm) high non-beveled vertical surface on the exterior side of weathertight doors where such vertical surfaces are required by the administrative authority to meet door sealing requirements (see Figure V404.2.5.2.2).  Although this vertical surface is permitted to be located at the top of the ramps used in the double and single ramp access methods, it is recommended that alternatives be explored with the administrative authority before using this exception in conjunction with either the double or single ramp access methods.  Alternatives may consist of drainage systems which collect leakage where doors seal against ramp surfaces.

 

Where it is not feasible to comply with the second configuration of access, an exception in V404.2.5.2 allows the third configuration of access to be used.  The third configuration consists of watertight doors with 1¼ inches (32 mm) high non-beveled thresholds on only one side of the doors.

 

The figure shows an elevation view of a door threshold.  On the right side of the threshold is the door which seals against a 3/4 inch high threshold.  A statement is included which says where permitted by V404.2.5 exception 4, non-beveled thresholds ¾ inch (19 mm) high on the sealing side of the door are allowed.  On the left side of the threshold, a ½ inch high beveled threshold is shown.  A statement on this side is included which says thresholds on non-sealing sides shall comply with V404.2.5.1, V302, and V303.

 

V404.2.5.1 Doors without Coamings.  Thresholds shall be ½ inch (13 mm) high maximum.  Raised thresholds and changes in level at doorways shall comply with V302 and V303.

EXCEPTION:  In alterations, existing thresholds more than ½ inch (13 mm) high shall be permitted provided the thresholds do not exceed a height of ¾ inch (19 mm) and have a beveled edge on each side of the thresholds with a slope not steeper than 1:2.

 

V404.2.5.2 Doors with Coamings.  Doors and doorways permitted to comply with V404.2.5.2 shall comply with V404.2.5.2.1 or V404.2.5.2.2.

EXCEPTION:  Where the administrative authority determines space limitations make it not feasible to comply with V404.2.5.2 and watertight doors are provided instead of coaming equipped weathertight doors, the thresholds on the side of the watertight doors containing the door seal are permitted to have non-beveled thresholds 1¼ inches (32 mm) high maximum.

 

V404.2.5.2.1 Doors with Double Ramp Access.  The height of thresholds on both sides of the doors shall be equal to or less than the minimum coaming height allowed by the administrative authority provided the doors are automatic and comply with V404.3.

 

The figure shows an elevation view of a door with a high sill, known as a coaming, at the bottom.  Two ramps, one on each side of the coaming, slope up and join at the top of the coaming -- forming an inverted shallow V.  Three statements are located within the figure which indicates where in the guidelines various provisions and exceptions allow installation of these double ramps.  The first states that no landings are required at the top of the double ramps (V405.7 exception).  The second states that these doors are required to be automatic (V404.2.5.2.1).  The third states that maneuvering clearances are allowed to be sloped (V404.2.4.4. exception 1).  An additional statement is provided in the figure to remind readers that the maximum slope for ramps is 1:12 (V405.2).

 

V404.2.5.2.2 Doors with Single Ramp Access.  The thresholds on the ramped side of the doors shall have a height equal to or less than the minimum coaming height allowed by the administrative authority.

 

The figure shows an elevation view of a door with a high sill, known as a coaming, at the bottom.  On one side of the coaming, a ramp slopes up to the top of the coaming.  Three statements are provided which indicate where in the guidelines provisions and exceptions allow installation of this single ramp on one side of the door.  The first states that no landing is required at the top of the ramp (V405.7 exception) and the second states that maneuvering clearance on the ramp side of the coaming is permitted to be sloped (V404.2.4.4 exception 2).  The third states that the slope is permitted to be 1:8 maximum for a 3 inch maximum rise and 1:10 maximum slope for a 6 inch maximum rise (V405.2 exception 2).  On the other side, a 48 inch minimum maneuvering clearance is shown connecting to the top of the coaming.  From that maneuvering clearance, a ramp slopes down and away from the maneuvering clearance and door.  Two statements are provided on this side of the door.  The first states that if the largest deck is less than 3,000 square feet, the maneuvering clearance is allowed to be 48 inches minimum (V404.2.4 exception 3).  The second states that the maximum slope for the ramp shown on the side of the door with a maneuvering clearance is 1:12 (V405.2).

 

 

The figure shows an elevation view of a threshold at a door with single ramp access.  On the right side of the threshold, a ramp leads up to the threshold and ends ¾ inches below the threshold top.  A door is shown sealing against this ¾ inch threshold.  A statement is included which says “where permitted by V404.2.5 exception 4, non-beveled thresholds ¾ inch (19 mm) high on the sealing side are allowed”.  On the left side of the threshold, a ½ inch high beveled threshold is shown.  A statement is included which says “thresholds on non-sealing sides shall comply with V404.2.5.1, V302, and V303”.

 

V404.2.6 Doors in Series and Gates in Series.  The distance between two hinged or pivoted doors in series and gates in series shall be 48 inches (1220 mm) minimum plus the width of doors or gates swinging into the space.

 

V404.2.7 Door and Gate Hardware.  Handles, pulls, latches, locks, and other operable parts on doors and gates shall comply with V309.4.  Operable parts of such hardware shall be 34 inches (865 mm) minimum and 48 inches (1220 mm) maximum above the finish deck surface.  Where sliding doors are in the fully open position, operating hardware shall be exposed and usable from both sides.

EXCEPTIONS:  1.  In alterations, existing locks shall be permitted in any location at existing glazed doors without stiles, existing overhead rolling doors or grilles, and similar existing doors or grilles that are designed with locks that are activated only at the top or bottom rail.

2.  Access gates in barrier walls and fences protecting pools, spas, and hot tubs shall be permitted to have operable parts of the release of latch on self-latching devices at 54 inches (1370 mm) maximum above the finish deck surface, provided the self-latching devices are not also self-locking devices and operated by means of a key, electronic opener, or integral combination lock.

 

Advisory V404.2.7 Door and Gate Hardware.  Door hardware that can be operated with a closed fist or a loose grip accommodates the greatest range of users.  Hardware that requires simultaneous hand and finger movements require greater dexterity and coordination, and is not recommended.

 

V404.2.8 Closing Speed.  Door and gate closing speed shall comply with V404.2.8.

 

V404.2.8.1 Door Closers and Gate Closers.  Door closers and gate closers shall be adjusted so that from an open position of 90 degrees, the time required to move the door to a position of 12 degrees from the latch is 5 seconds minimum.

 

V404.2.8.2 Spring Hinges.  Door and gate spring hinges shall be adjusted so that from the open position of 70 degrees, the door or gate shall move to the closed position in 1.5 seconds minimum.

 

V404.2.9 Door and Gate Opening Force.  The force for pushing or pulling open interior and exterior sliding and folding doors, and interior hinged doors and gates, shall be no more than 5 pounds (22.2 N) maximum.

EXCEPTIONS:  1.  Doors on sailing vessels shall not be required to comply with V404.2.9.

2.  Where the administrative authority has determined that forces greater than 5 pounds (22.2 N) are necessary for fire doors, watertight doors or other doors, the maximum opening force shall be permitted to be established by the administrative authority for such doors.

 

Advisory V404.2.9 Door and Gate Opening Force.  The maximum force pertains to the continuous application of force necessary to fully open a door, not the initial force needed to overcome the inertia of the door.  It does not apply to the force required to retract bolts or to disengage other devices used to keep the door in a closed position.

 

V404.2.10 Door and Gate Surfaces.  Swinging door and gate surfaces within 10 inches (255 mm) of the finish deck surface measured vertically shall have a smooth surface on the push side extending the full width of the door or gate.  Parts creating horizontal or vertical joints in these surfaces shall be within 1/16 inch (1.6 mm) of the same plane as the other.  Cavities created by added kick plates shall be capped.

EXCEPTIONS:  1.  Sliding doors shall not be required to comply with V404.2.10.

2.  Tempered glass doors without stiles and having a bottom rail or shoe with the top leading edge tapered at 60 degrees minimum from the horizontal shall not be required to meet the 10 inch (255 mm) bottom smooth surface height requirement.

3.  Doors and gates that do not extend to within 10 inches (255 mm) of the finish deck surface shall not be required to comply with V404.2.10.

4.  In alterations, existing doors and gates without smooth surfaces within 10 inches (255 mm) of the finish deck surface shall not be required to provide smooth surfaces complying with V404.2.10 provided that if added kick plates are installed, cavities created by such kick plates are capped. 

 

V404.2.11 Vision Lights.  Doors, gates, and side lights adjacent to doors or gates, containing one or more glazing panels that permit viewing through the panels shall have the bottom of at least one glazed panel located 43 inches (1090 mm) maximum above the finish deck surface.

EXCEPTION:  Vision lights with the lowest part more than 66 inches (1675 mm) from the finish deck surface shall not be required to comply with V404.2.11.

 

V404.3 Automatic and Power-Assisted Doors and Gates.  Automaticdoors and automatic gates shall comply with V404.3.  Full-powered automatic doors shall comply with ANSI/BHMA A156.10 (incorporated by reference, see “Referenced Standards” in Chapter 1).  Low-energy and power-assisteddoors shall comply with ANSI/BHMA A156.19 (1997 or 2002 edition) (incorporated by reference, see “Referenced Standards” in Chapter 1).

 

V404.3.1 Clear Width.  Doorways shall provide a clear opening of 32 inches (815 mm) minimum in power-on and power-off mode.  The minimum clear width for automatic door systems in a doorway shall be based on the clear opening provided by all leaves in the open position, unless the breakout opening requirement in V404.3.6 applies.

 

V404.3.2 Maneuvering Clearance.  Clearances at power-assisted doors and gates shall comply with V404.2.4.  Clearances at automaticdoors and gates without emergency power and serving an accessible means of escape shall comply with V404.2.4.

EXCEPTION:  Where automatic doors and gates remain open in the power-off condition, compliance with V404.2.4 shall not be required.

 

V404.3.3 Thresholds.  Thresholds and changes in level at doorways shall comply with V404.2.5.

 

V404.3.4 Doors in Series and Gates in Series.  Doors in series and gates in series shall comply with V404.2.6.

 

V404.3.5 Controls.  Manually operated controls shall comply with V309.  The clear deck space adjacent to the control shall be located beyond the arc of the door swing.

 

V404.3.6 Break Out Opening.  Where doors and gates without emergency power are a part of an accessible means of escape, the clear break out opening at swinging or sliding doors and gates shall be 32 inches (815 mm) minimum when operated in emergency mode.

EXCEPTION:  Where manual swinging doors and gates comply with V404.2 and serve the same accessible means of escape, compliance with V404.3.6 shall not be required.

 

Advisory V404.3.6 Break Out Opening.  Break out openings are typically on sliding doors and enable passengers to pass through doorways equipped with automatic doors during emergencies where normal ship’s power is not available.

 

V404.3.7 Revolving Doors, Revolving Gates, and Turnstiles.  Revolving doors, revolving gates, and turnstiles shall not be part of an accessible route.

 

 

V405 Ramps

 

V405.1 General.  Ramps on accessible routes shall comply with V405.

EXCEPTION:  In assembly areas, aisle ramps adjacent to seating and not serving elements required to be on an accessible route shall not be required to comply with V405.

 

V405.2 Slope.  Ramp runs shall have a running slope not steeper than 1:12.

EXCEPTIONS:  1.  In alterations, ramps shall be permitted to have running slopes in accordance with Table V405.2 where such slopes are necessary due to space limitations.

2.  At doors with coamings providing single ramp access in accordance with V404.2.5.2.2, ramp slopes shall be permitted to comply with Table V405.2.

3.  Where ramps connect to platforms of manually powered boarding lifts complying with V414, ramps shall be permitted to have running slopes which do not exceed 1:8 provided the rise of the ramps do not exceed 3 inches (75 mm).

 

Table V405.2 Alternate Ramp Slopes Permitted by Exceptions 1 and 2

Slope1

Maximum Rise

Steeper than 1:10 but not steeper than 1:8

3 inches (75 mm)

Steeper than 1:12 but not steeper than 1:10

6 inches (150 mm)

1.        A slope steeper than 1:8 is prohibited.

 

Advisory V405.2 Slope.  To accommodate the widest range of users, provide ramps with the least possible running slope and, wherever possible, accompany ramps with stairs for use by those individuals for whom distance presents a greater barrier than steps, e.g., people with heart disease or limited stamina.

 

V405.3 Cross Slope.  Cross slope of ramp runs shall not be steeper than 1:48.

 

Advisory V405.3 Cross Slope.  Cross slope is the slope of the surface perpendicular to the direction of travel.  Cross slope is measured the same way as slope is measured (i.e., the rise over the run).

 

V405.4 Deck Surfaces.  Deck surfaces of ramp runs shall comply with V302.  Changes in level other than the running slope and cross slope are not permitted on ramp runs.

 

V405.5 Clear Width.  The clear width of a ramp run and, where handrails are provided, the clear width between handrails shall be 36 inches (915 mm) minimum.

EXCEPTION:  Where the largest deck of a passenger vessel is less than 3000 square feet (279m2) in size, the width of ramp runs and the distance between handrails, if provided, shall be permitted to have clear widths of 32 inches (815 mm) minimum.

 

V405.6 Rise.  The rise for any ramp run shall be 30 inches (760 mm) maximum.

 

V405.7 Landings.  Ramps shall have landings at the top and the bottom of each ramp run.  Landings shall comply with V405.7.

EXCEPTION:  Landings at tops of ramps are not required at doors with coamings providing double or single ramp access in accordance with V404.2.5.2.

 

Advisory V405.7 Landings.  Ramps that do not have level landings at changes in direction can create a compound slope that will not meet the requirements of this document.  Circular or curved ramps continually change direction.  Curvilinear ramps with small radii also can create compound cross slopes and cannot, by their nature, meet the requirements for accessible routes.  A level landing is needed at the accessible door to permit maneuvering and simultaneously door operation.
