Scope. This Article establishes safety requirements for
the cleaning of all windows of all buildings. Window cleaning includes
operation(s) of washing, wiping or other methods of cleaning windows, window
frames, curtain wall components, building panels, etc.
NOTE: It is recognized because of special site
conditions that certain provisions in Article 6 may be applicable and can be
used in conjunction with equipment and/or practices in this article.
(a) Windows shall not to be cleaned from the
outside or inside unless means are provided to enable such work to be done in a
safe manner as provided in these orders.
(b) Provisions for preventing accidents due
to overhead high voltage lines shall be in conformance with the High Voltage
Electrical Safety Orders, Article 37.
(c) Employers shall provide their window
cleaning employees with safety equipment and devices conforming with the
requirements of these orders, and shall maintain such equipment in safe
condition at all times.
(d)
Employers shall instruct their window cleaning employees in the proper use of
all equipment provided to them, and shall supervise the use of the equipment
and safety devices to insure that safe working practices are
observed.
(e) All employees
cleaning windows shall use safety devices and equipment as required
herein.
(f) Only employees who have
been properly trained to handle such equipment shall be assigned to work from
scaffolds or boatswain's chairs.
(g)
(1) In
every building where window cleaning operations are performed in such a manner
that a person stands on the sill in order to clean the window or works from the
inside where the window opening is of such size that it would be possible to
fall through the open window to the outside, there shall be installed window
cleaning safety anchors or other anchorages approved by the Division. (Title
24, Part 2, Section 2-8502(a).)
(2)
Any window which when fully opened has a clear opening with the lesser
dimension exceeding 18 inches, or any window in which the height to width
relationship presents a hazard, shall be considered as presenting the hazard of
falling through as specified in Section
3282(g)(1) above.
(Title 24, Part 2, Section 2-8502(a)2.)
(3) In every building other than those
described in Section
3282(g)(1),
provisions shall be made for window cleaning by use of elevating platforms,
rolling scaffolds, suspended scaffolds, boatswain's chairs, or ladders, as
specified in these orders. (Title 24, Part 2, Section
2-8502(a)1.)
(h) Lag
screws shall not be used in new or replacement installations. (Title 24, Part
2, Section 2-8502(b).)
(i) All
glass draft deflectors shall be free of sharp edges that could cut workers
removing deflectors in connection with the window cleaning
operations.
(j) Safety equipment,
scaffolds and their components shall not be used with acids or other corrosive
substances, or in corrosive atmospheres except when adequate precautions are
taken to protect the scaffold from damage in accordance with recommendations of
the corrosive substance manufacturer and the scaffold manufacturer.
(k) Special precautions shall be taken by the
user to protect scaffold members, including any wire, fiber, or synthetic rope,
when a heat-producing process is in use. Ropes that have been contacted by the
heat-producing process shall be considered to be permanently damaged and shall
not be used for scaffold support.
(l) Window cleaners shall not pass from one
window sill to another window sill on the outside of a building unless one belt
terminal is connected at all times.
(m) Window cleaners shall not be permitted to
work from any sill on which there is any obstruction or a slippery substance
that might impair their footing.
(n) Washing from the sill shall not be
permitted unless there is a certain minimum standing room on the sill in
relation to its slope. Permissible sill width and slope combinations are shown
in Fig. 1.

SLOPE OF STILL OR SURFACE (DEGREES BELOW
HORIZONTAL)
The chart above shows the relationship between minimum
permissible sill widths and various sill slopes for washing windows from a
standing position on the sill. If the point of intersection of a vertical line
from the slope value with a horizontal line from the sill width value falls in
the unshaded area, washing windows from a standing position on the sill is
permissible. It is not permissible if the intersection falls anywhere in the
shaded area.
(o) No employee
shall be permitted to work from, stand or walk on any surface that is not rated
for such live loading by the building's engineer of record and/or a building
official. (Title 24, Part 2, Section 2-8502(c))
(p)
(1)
(A) Building owners shall provide the
employer written assurance, before use, that all their building's safety
devices and equipment meet the provisions of these orders. The written
assurance shall consider, but not be limited to: window anchors and fittings;
load sustaining capabilities of platforms, building components, hoisting and
supporting equipment; stability factors for carriages, platforms and supporting
equipment; maximum horizontal force for movement of carriages and davits;
design of carriages, hoisting machines, wire rope and stabilization systems;
and design criteria for electrical wiring and equipment.
(B) All safety devices and equipment
considered in the written assurance shall be inspected at least every 12
months. All safety devices and parts of such equipment, including related
building support structures, shall be inspected and where necessary, tested to
determine if they are safe to use or operate. All such tests shall be conducted
as required in Section
3296(b).
(C)
1.
Owners of buildings 36 feet or more in height shall have an Operating
Procedures Outline Sheet (OPOS) where one or more of the following conditions
apply to such buildings:
A. A building does
not have established window cleaning system or procedures meeting the
requirements specified in Articles 5 and 6, or
B. A building's original window cleaning
procedures prepared in accordance with the requirements in Articles 5 and 6
have been changed because of building modifications, or
C. A building has extreme architectural
features, which require the use of complex rigging or equipment, or a building
that uses rigging or equipment not covered by these Orders.
2. An OPOS shall be developed by a person(s)
with knowledge in the design, installation and use of building maintenance
equipment (i.e., possessing Scaffold Inspection Testing certification as
specified in Section
3296). The OPOS shall be written in
a manner that can be readily understood by the employers. An OPOS that requires
structural modifications to the building or existing building maintenance
equipment shall have such modifications designed by a mechanical, structural or
civil engineer currently registered in the State of California with experience
in the design and installation of such equipment.
3. An OPOS shall be developed which at a
minimum shall contain the elements of Appendix A of this
Article.
(2)
Employers shall not permit their employees to use any building safety devices
or equipment prior to receiving copies of the written assurance and, if
required, an OPOS from the building owner as required by Section
3282(p)(1)(A) and
(C) above.
