hoistways shall be guarded in compliance with this section.
(ii) Where any point on a moving car or
counterweight passes less than eight feet from a floor, scaffold platform or
other work surface or position, such floor, scaffold platform or other work
surface so exposed shall be provided with a partition at least six feet in
height. Such partition shall extend horizontally at least five feet past the
horizontal project of the path of the car or counterweight. Such partition
shall be at least equal in construction to hoistway enclosures as specified in
this section.
(4)
Running clearances. Every hoistway enclosure shall be so installed and
reinforced in all areas subject to external pressure that the running
clearances between car and enclosure cannot be reduced to less than one inch
upon the application of any horizontal pressure of 100 pounds against any point
on such enclosure.
(d)
Hoistway doors.
(1) Every entrance opening in
any hoistway enclosure for a personnel hoist shall be provided with a solid
door at least 78 inches in height which shall extend across the full width of
the opening. Such door shall be provided with a vision panel securely covered
with wire mesh. Such door shall be provided with a lock or latch which is
openable from the hoistway side only and inaccessible from the landing side.
Every such door shall have an underclearance of not more than one-half inch.
Exception:Such entrance door at the lowest landing of any
hoistway shall be provided with a means, accessible only to designated persons,
for unlocking the door from the landing side.
(2) In normal service every hoistway door
shall be locked or latched shut except when in use for passage to or from the
car. No person except the car attendant shall open any such door.
(3) Hoistway entrance doors shall be hung to
provide durability and shall be securely reinforced.
(e) Car enclosures. The car of every
personnel hoist shall be permanently enclosed on all sides and the top except
the side used for entrance or exit. Such enclosure shall be equivalent in
strength to two-inch planking laid tight. The top of every such enclosure shall
be provided with an emergency exit opening fitted with a hinged hatch cover.
Such exit opening shall be not less than 16 inches in its smallest dimension
and not less than 400 square inches in area.
(f) Car doors or gates.
(1) Each landing side of any car used in a
personnel hoist shall be provided with a door or gate at least six feet in
height constructed of material at least as equivalent in strength as the car
enclosure.
(2) Every opening in
such door or gate shall be of such size and shape as to reject a three- inch
diameter ball at any point.
(3)
Every such car shall be equipped with an approved electrical contact so
arranged that the car cannot be operated unless each door or gate is
shut.
(g) Wiring. Wiring
and other electrical equipment shall be of proper quality and properly
installed. Electrical installations shall be in accordance with the 1971
National Electrical Code. Hoistway wiring may consist of heavy-duty
