Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
					 During roofing operations the employer shall comply with the provisions of
					 Section 1509 and employees shall be trained
					 and instructed in accordance with the provisions of Section
					 1510 of these orders.
(b) Slopes 0:12 to 4:12--Single-Unit
					 (Monolithic) Roof Coverings.
(1) Employees
					 shall be protected from falls from roofs of a height of more than 20 feet by
					 use of one or a combination of the methods in this section. Whenever felt
					 laying machines or other equipment that is pulled by an operator who walks
					 backwards is being used, this provision shall apply regardless of the
					 height.
(2) Warning lines
					 consisting of rope, wire or similar material, flagged with highly visible
					 material hanging from the warning lines at approximately 6-foot intervals,
					 shall be installed 34 to 45 inches above the roof surface to warn employees
					 that they are approaching the edge of the roof.
(A) The stanchions (portable or fixed)
					 supporting the warning lines shall be designed and installed to minimize tip
					 over or displacement under normal working conditions.
(B) Warning lines shall have a minimum
					 tensile strength of 500 pounds.
(C)
					 The line shall be attached at each stanchion in such a way that pulling on one
					 section of the line between stanchions will not result in slack being taken up
					 in adjacent sections before the stanchion tips over.
(3) Unless conditions prohibit, headers
					 consisting of sheets of roofing or other roofing materials shall also be laid
					 parallel to the edges of the roof to warn employees that they are approaching
					 the edge of the roof.
(4) The
					 warning lines and headers shall be placed no closer than 5 feet from the roof
					 edge.
(5) When using felt-laying
					 machines or other equipment that is pulled by an operator who walks backwards
					 or motorized equipment on which the operator rides, the headers shall be placed
					 no closer than 10 feet and the warning lines shall be placed no closer than 5
					 feet from those roof edges that are perpendicular (or nearly so) to the
					 direction in which the operator is moving and when conditions prohibit the use
					 of headers, the warning lines shall be placed no closer than 10 feet from those
					 roof edges that are perpendicular (or nearly so) to the direction in which the
					 operator is moving.
(6) The warning
					 lines and headers shall be erected either around the complete perimeter of the
					 roof or only in areas of the roof where work is being accomplished, so long as
					 the warning lines and headers are moved as the work progresses in such a manner
					 as to provide continuous warning to employees in the work area when they
					 approach the roof edge. Access paths shall be erected as follows:
(A) Points of access, materials handling
					 areas and storage areas shall be connected to the work area by a clear access
					 path formed by two warning lines.
(B) When the path to a point of access is not
					 in use, a rope, wire, or chain, equal in strength and height to the warning
					 line, shall be placed across the path at the point where the path intersects
					 the warning line erected around the work area.
(7) Employees shall be instructed to stay
					 inside the warning lines and headers except when work must be performed at the
					 roof edge.
(8) Application of
					 materials outside the warning lines shall be closely supervised by a qualified
					 person.
(9) On narrow roofs and
					 roofs of unusual shape where warning lines and headers would be impractical,
					 the application of materials shall be closely supervised by a qualified
					 person.
(10) When a felt-laying
					 machine or any other equipment that is pulled by an operator who walks
					 backwards is being used, the operator shall be no closer than 3 feet to the
					 roof edges that are parallel (or nearly so) to the direction in which the
					 operator is moving. Motorized equipment on which the operator rides shall not
					 be used or stored between the warning line and the roof edge.
NOTE: The provisions of subsection (b) do not apply when
						employees are protected by the use of one or a combination of the following
						methods:
Personal Fall Protection [Section
						1724(f)] .
Catch Platforms [Section
						1724(c)] .
Scaffold Platforms [Section
						1724(d)] .
Eave Barriers [Section
						1724(e)] .
Standard Railings and Toeboards (Article 16). Parapets at
						least 24 inches high; except that at those job sites where feltlaying machines
						or other equipment that is pulled by an operator who walks backwards or
						motorized equipment on which the operator rides is being used, the provisions
						of this subsection shall not apply provided that the parapet is 36 inches or
						more in height at those roof edges which are perpendicular (or nearly so) to
						the direction in which the equipment is moving.
