General requirements.
(1) Roofing brackets.
(i) Required use. Roofing brackets shall be
used whenever work is to be performed on any roof having a slope steeper than
one in four inches unless crawling boards or approved safety belts are used in
compliance with this Part (rule).
(ii) Roofing bracket construction. Roofing
brackets shall be constructed and installed to fit the pitch of the roof and
when in use shall provide a level working platform.
(iii) Roofing bracket installation. Roofing
brackets shall be secured in place by nailing, by securely driving into the
roof the pointed metal projections which are attached to the undersides of
roofing brackets or by means of first grade manila rope or synthetic fibre rope
at least three-quarters inch in diameter which is passed over the ridge poles
and tied.
(2) Crawling
boards.
(i) Crawling board construction.
Crawling boards shall be at least 10 inches in width and one inch in thickness.
Each crawling board shall be provided with cleats which are at least one and
one-half inches in width by one inch in thickness. Such cleats shall be spaced
at equal intervals across the full width of the board and shall be firmly
nailed. Cleat nails shall be driven through and clinched or shall be of the
screw type. Crawling boards shall extend from the ridge poles to the eaves when
used in connection with roof construction, repair or maintenance.
(ii) Crawling board installation. Crawling
boards shall be secured to a roof by ridge hooks or equally effective
means.
(iii) Crawling board
lifeline. A lifeline in compliance with this Part (rule) shall be strung beside
each crawling board.
(b) High and steep roofs. Where any work is
being performed in the construction, repair or maintenance of any roof without
a parapet at least two and one-half feet in height and such roof is more than
20 feet in height measured from the ground or grade level to the exterior edge
of the eaves and the slope of such roof is greater than one in four, a
ground-supported scaffold in compliance with this Part (rule) shall be
provided. Such scaffold shall be installed beneath the work area with the
scaffold platform not more than two feet below the exterior edges of the eaves
of the roof. Such scaffold shall be of sufficient width to extend outward at
least two feet from the exterior roof edge and the scaffold platform shall be
provided with a safety railing constructed and installed in compliance with
this Part (rule). In addition, persons performing such work shall be protected
against sliding by means of roofing brackets or crawling boards installed and
used in compliance with this Part (rule). Such roofing brackets or crawling
boards are not required in cases where every employee engaged in work on such
roof is provided with and used as approved safety belt or harness securely
attached to a lifeline in compliance with this Part (rule).
(c) Protection of persons using roofing
machines. Where persons are using roofing machines on any roof which does not
have a parapet at least three feet in height installed around the perimeter of
such roof, protection from falling shall be provided for such persons as
follows:
(1) If the work area extends to any
edge of the roof, such edge shall be provided with a safety railing constructed
and installed in compliance with this Part (rule) or a ground-supported
scaffold in compliance with this Part (rule) shall be provided. Such scaffold
shall be installed the length of the work area with the scaffold platform level
with the roof edge elevation. Such scaffold shall be of sufficient width to
extend outward from the roof at least two feet. The scaffold platform shall be
provided with a safety railing constructed and installed in compliance with
this Part (rule) and the space between the scaffold platform and the roof shall
not be more than six inches.
(2) If
such work does not extend to any roof edge, portable stanchions located five
feet in from the roof edge and connected by ropes or chains shall be provided.
Such stanchions shall be spaced so that the connecting ropes or chains shall
not be less than 36 nor more than 48 inches above the roof surfaces.
(d) Hot roofing material
transporters, also known as hot luggers. Closed containers or devices used for
transporting molten roofing materials from fill stations to the application
areas on roofs shall be equipped with at least the following safety features in
order to minimize hazards to persons caused by blowbacks of the molten roofing
materials:
(1) Existing transporters. On or
before January 1, 1973, every existing transporter shall be equipped with the
following safety devices:
(i) The fill pipe
cover shall be provided with a safety latch designed and installed to keep the
cover in place at all times except during filling operations.
(ii) On top of every such transporter remote
from the fill pipe there shall be installed an automatic venting device
designed to release any accumulation of gas pressure. Such venting device shall
be inspected daily to assure proper operation.
(2) New transporters. Every transporter
manufactured after January 1, 1973 shall be equipped with the following safety
devices:
(i) The fill pipe cover shall be
provided with a safety latch designed and installed to keep the cover in place
at all times except during filling operations.
(ii) Every such transporter shall be
automatically vented or so constructed as to prevent the accumulation of gas.
Every such transporter shall be inspected daily to assure proper
operation.
(iii) Manufacturers of
hot roofing material transporters shall furnish written operating and safety
instructions with every transporter.
