Cal. Code Regs. Tit. 8, § 1663 - Float Scaffolds
(a) Scaffolds of this type are to support not
more than three employees and light tools, such as those needed for riveting,
bolting, and welding. They shall be constructed as follows, unless substitute
designs and materials provide equivalent strength, stability, and safety (See
B-38, Appendix).
(1) The platform shall be
not less then 3 feet wide and 6 feet long, made of ¾ inch plywood,
equivalent to Douglas Fir Plywood Association Grade A-A Exterior.
(2) Under the platform, there shall be 2
supporting bearers made from 2-inch by 4-inch "selected lumber," or better.
They shall be free of knots or other flaws and project 6 inches beyond the
platform on both sides. The ends of the platform shall extend about 6 inches
beyond the outer edges of the bearers. Each bearer shall be fastened to the
platform by at least two ½ inch-diameter bolts.
(3) An edging of wood not less than ¾
inch by 1 ½ inches, or equivalent, shall be placed around all sides of
the platform to prevent tools from rolling off.
(4) Supporting ropes shall be 1-inch-diameter
Manila rope, or equivalent, free from deterioration, chemical damage, flaws, or
other imperfections. Rope connections shall be such that the platform cannot
shift or slip. If two ropes are used with each float, they shall be arranged so
as to provide four ends which are to be securely fastened to an overhead
support. Each of the two supporting ropes shall be hitched around one end of a
bearer and pass under the platforms to the other end of the bearer where it is
hitched again, leaving sufficient rope at each end for the supporting
ties.
(5) Each employee working
from a float scaffold shall be provided with and use fall protection in
accordance with the requirements of Article 24.
