WAC 296-150C-1180
Commercial coach exits. When
applicable, a commercial coach must comply with International Building Code, Chapter 11 Accessibility and with
the following requirements:
(1) Commercial coaches must have at least two exterior
doors that are remote from each other. Remote means that in:
(a) Single-wide units the doors may not be less than
twelve feet apart; and
(b) Multiwide units the doors may not be less than twenty
feet apart, center to center from each other measured in a
straight line direction regardless of the length of travel
between doors.
Exception:
A commercial coach that is twenty-four feet long or less needs only one exit door, unless it has a dormitory sleeping area.
(2) Exterior doors must be constructed for exterior use. Exterior doors must provide at least a thirty-five inch wide
by seventy-nine inch high clear opening (36" x 80" door). Each swinging exterior door must have a key-operated lock that
has a deadlock latch. A deadlock with a passage set installed
below the deadlock may be used as an acceptable alternate for
each exterior door. The locking mechanism must be engaged or
disengaged by the use of a lever or other device from the
interior of the commercial coach. Locks must not require the
use of a key for operation from the inside.
(3) Every room designed for dormitory sleeping, unless it
has an exterior exit door, must have at least one window which
can be opened from the inside without using tools. This
window must provide a clear opening of at least twenty-two
inches in its smallest dimension and five square feet in area
with the bottom of the opening not more than three feet above
the floor. If a screen or storm window is used it must be
readily removable without using tools.
